Tips from stylists and hairdressers

Highlighting is a convenient and safest way to highlight gray hair. Professional stylists recommend doing this procedure using shading. However This method is not suitable for all gray-haired women.

In order for unstable tint products to be applied to the strands, the hair must be healthy and not coarse, and the number of gray strands should not exceed 30% of the total hair mass. Tinting agents can add brightness and saturation to the natural color, and gray strands will be slightly lighter than the rest. This method will create an interesting play of color and allow you to rejuvenate your face.

Remember! Tint products should be as close as possible in tone to the natural hair color.

To date there are many highlighting techniques. Thanks to this diversity, every girl can create her own unique look, but some types of coloring are not suitable for everyone.

So we can say with confidence that some coloring techniques will not look at all on gray hair. Here you need to take into account that gray hair can be either light or dark. Therefore, you should choose a technique depending on the shade of your natural hair.

The effect of coloring primarily depends on the correct choice. Even if the hair is a little With gray hair, the shade is selected based on the original hair color:

1. 
   
   
   
   All shades of brown, copper, and gold will harmonize perfectly with dark brown hair, but white shades such as ivory, wheat, platinum, and milk will suit light brown hair with gray hair. Shades such as ash, platinum, and silver deserve special attention. They will highlight gray hair and make it more expressive;
2. highlighting black hair with gray hair requires special skill from the hairdresser, because an illiterate approach in this matter can completely ruin the hairstyle. When highlighting black or very dark hair, cool shades are usually chosen; you can also experiment with bronze tones. Unlike brunettes, brown-haired women with dark hair are recommended to choose warm shades;
3. For light strands, choosing the right shade is quite easy, because they are all very similar to each other. Even if the stylist makes a slight mistake with the choice, it will still look harmonious and natural. Moreover, blonde hair does not have to be dyed; sometimes it can simply be shaded or oxidized;
4. There are not many women on our planet with natural reddish hair color. This is why choosing shades for highlighting redheads is the most difficult thing. For light red hair, peach, caramel, and golden shades are suitable, but in this case, after highlighting, the red hair will look more like blond. But for dark red strands you need to choose reddish and copper shades.

Color options

You can decorate gray hair not only with a well-chosen shade, but also with the right length of curls. So Perfect for women with long and medium dark hair:

1. Venetian highlighting. In this case, dark strands are dyed with a slight indentation from the roots. The result of this technique is strands that are slightly faded under the sun;
2. coloring shatush Suitable for any length. Sometimes the result of this technique is barely noticeable, because it seems as if the sunbeams are playing in your hair;
3. ombre technique It will also look great on hair of any length. Ombre is a transition from a lighter tone at the roots to a darker tone at the ends. This technique will allow you to beautifully highlight gray strands at the roots, as well as leave natural color at the ends. This technique will look best on dark hair.

Don’t forget that the type of highlighting should be chosen depending on the number of gray strands. If the gray hair has only slightly touched the temples or the back of the head, it can be beautifully disguised. But for those whose hair is completely shrouded in gray, there is an excellent technique called “salt-pepper.”

The name of this technique speaks for itself. It represents a smooth transition from a light gray shade (salt) to black tones (pepper). It is perfect for those ladies who have most of their hair gray. Thanks to the right combination of gray and black strands, it will be completely invisible.

Technologies

Highlighting gray strands is done in four different ways. Choose the one that suits you directly.

1. 
   
   
   
   cap. This classic method is now outdated. Now it is used exclusively for dyeing short strands. The process is quite labor-intensive and very lengthy, so repeating it at home will be quite difficult. A special cap with a large number of holes is put on the head. Strands of hair are pulled out through these holes with a crochet hook. The coloring composition is applied exclusively to elongated strands.
2. Foil. This is a more modern color option. It allows you to perfectly color long strands, as well as medium-length curls.
3. Comb. This technique is suitable for curls of absolutely any length. The coloring composition is applied to a wide-toothed comb, after which individual sections of the hair are combed with it.
4. Hands. This technique is also called “frosting”, as well as “glazing”. It is most often used for curly or curly hair.

Let's look at one of the options more specifically. Because highlighting on foil is the most common, let's go a little deeper into the details of this procedure.

1. First of all, you need to prepare your work area, remove all unnecessary items, and cut the foil.
2. It is best to start coloring with a parting. Use the thin tip of a comb or a special hook to pull out a strand and place it on the foil.
3. Now you need to treat the strand with a coloring solution.
4. After applying the paint, the strand must be completely wrapped in foil so that the paint does not transfer to other curls.
5. A similar procedure should be repeated with each strand, at equal distances.

Remember! The back of the head should be painted last.

That's all. The foil highlighting procedure is completely completed. Everything turned out to be not as difficult as it seemed at first.

How long does the result last?

This coloring lasts much longer than regular hair coloring. The fact is that gray hair and growing roots are not so noticeable during highlighting, so the procedure should be repeated much less often.

We should not forget that you can extend the life of your hairstyle. To do this, you need to use shampoos and balms for colored hair, hide your beautiful strands during the scorching sun, severe frost, try to wash your hair as little as possible so that the dye does not wash out.

Possible mistakes

Most often, mistakes during highlighting occur when the procedure is carried out independently, at home. However, sometimes hairdressers make some mistakes.

Yes, mostA common mistake is choosing the wrong tone. The hairstyle in this case looks very ugly, and sharp transitions are striking. Fixing this is not always easy or safe. If the result of home highlighting looks really ugly, stylists will suggest repeating the procedure to even out the shades.

However, this may not be safe for your hair at all. The dye, no matter what it is, negatively affects the structure of the hair, dries it out and makes it brittle. That is why the staining procedure cannot be carried out too often.

One more A common mistake is uneven strand width. This problem will also have to be corrected by repeating the procedure. In this case, the strands can only be made thicker. Their width will depend on the widest curls on your head.

The different width of the indentation from the roots is also very noticeable, especially on hair of dark shades. You can correct the situation in any beauty salon. During the correction, the stylist will try to align the indentation in the root zone as much as possible.

How to fix?

Sometimes even some masters get absolutely terrible results. If you have had unsuccessful highlighting, or you simply don’t like the result, The best option would be to dye your hair. However, this is not at all easy to do because due to the different shade of the curls, the new color will fall unevenly, and this will only aggravate the situation.

If you want to correct the results of unsuccessful highlighting, it is best to contact a salon where experienced hairdressers work. They know how to turn the situation to your advantage. First, you need to dye the lightest strands in darker colors to even out the overall shade of your hair, and then you can completely recolor all the strands.

Rules of care

In order for your hair to always look beautiful, you need to provide it with proper care. It will allow you to maintain not only a beautiful appearance, but also healthy hair.

It should be remembered that after such a procedure, the hair requires much more attention than even after regular dyeing. After highlighting, you may even feel that your curls have become weaker and thinner than they were before. In order to maintain their health, it is recommended to use various masks and balms marked “for colored hair.”

If you do not have the opportunity to purchase nourishing masks or balms, you can prepare your own from the ingredients that you find in your own kitchen. For example, prepare a nourishing mask from eggs or wash your strands with chamomile decoction.

In order for your hair to remain beautiful for much longer, try to avoid re-coloring until it is completely restored.

Conclusion

The highlighting procedure is very multifaceted. It will help not only hide gray hair, but also highlight it favorably. So, dear women, gray hair is not a death sentence. This is another opportunity to look original!

Gray hair causes women a lot of inconvenience, shaking their faith in their irresistibility and forcing them to look for ways to hide such unwanted “silver” in their strands. One of the effective methods that helps to cope with the problem is highlighting on gray hair. Like coloring, it has its own nuances, because giving whitened curls the desired shade is not so easy. Thanks to the recommendations of experts and detailed master classes on video, you will be able to effectively solve the problem and forget about gray hair for a certain time.

Can it be done on gray hair?

Gray hair does not only appear in women whose age is usually delicately called mature. The formation of silver strands is due to many factors, including genetic predisposition. That's why The first gray hair can occur before the age of 30.

A few hairs, especially on light brown hair, will not be so noticeable if you style it well. But hair turning gray strand by strand can be a problem. If “silver” covers less than half of all curls, you should resort to highlighting.

Attention! Early gray hair can signal problems with internal organs: liver disease, thyroid dysfunction, gastritis left to chance.

Numerous women's forums contain varied reviews about the procedure, noting that with its help it is possible to effectively disguise gray hair on dark, light, and light brown hair. The correct options for highlighting gray hair, taking into account the original color of the hair, help with this.

If you need to expressively emphasize the presence of “silver” on your head, ash, gray and other cold tones will be optimal. But they are not suitable for every woman, which means that in each specific case you will have to look for an individual solution. To hide gray hair, you can use shades that are close to natural or bright colors.

Stylists do not recommend using highlights if more than half of your hair has already turned white. 40–50% is a borderline value, but for dark curls the figure is reduced to 1/3 or 30% gray on the entire head. In this case, full coloring will be optimal, otherwise the hairstyle will look sloppy. If the hair has completely turned grey, highlighting is also possible, but with further tinting of the hair.

Advantages and disadvantages

Advantages of the procedure:

1. disguises whitened strands;
2. highlighting gray hair makes the image more expressive;
3. helps to emphasize the advantages of appearance;
4. gives extra volume to hair;
5. ennobles gray hair if it covers all curls;
6. does not require frequent correction - you can visit the salon every 3-4 months;
7. considered a gentle technique;
8. optimal for hair of various lengths.

Flaws:

1. gray hair does not have a natural pigment, so it does not absorb artificial dye well;
2. the result of the procedure can be disastrous, especially if highlights are applied to recently dyed hair;
3. requires the use of an aggressive composition that will not be quickly washed out;
4. dark curls need preliminary lightening;
5. sometimes yellowness appears, which is not so easy to remove;
6. strands can become dry and brittle, so they need special care;
7. There are restrictions and contraindications, including damaged, weak curls.

Price

When planning to go to the hairdresser, get ready to pay about 3-4 thousand rubles for highlighting on gray hair. Much will depend not only on which city you want to undergo the procedure (the most expensive services are in megacities), but also on a number of other factors.

These are the qualifications of the master, the length of the strands, the number of shades, and the chosen technique. Classic highlighting will cost less than the fashionable “salt and pepper”.

Not every technology can be applied at home. It is still better to entrust complex coloring to a professional. On your own or with an assistant, you can try the traditional method of highlighting (on a cap, foil, comb). In this case, the cost of the procedure will be equal to the cost of clarifier (about 200 rubles), paint (about 400 rubles), additional materials, and tools.

Types of highlighting suitable for gray hair

Classic. Hair is dyed evenly along its entire length, choosing thin strands. An option for women who have little gray hair.

Salt and pepper. This type of highlighting is suitable for those with ash-colored hair, as well as those whose curls have already become significantly whiter. The technology involves painting in several tones, from light gray to charcoal black. A combination of contrasting colors will perfectly hide gray hair. The method is used by women of different ages.

Coloring. Another method in which several shades are combined. They can be dark, light, bright, pastel. Such highlighting on gray hair is applicable in most cases, regardless of whether the blonde, brown-haired, or brunette liked it. The main thing is to successfully choose a palette of colors so as not to look vulgar, unkempt or too colorful.

Shatush. A smooth transition from dark roots to light, as if burnt out, ends is most often used on dark strands, but is also possible on light ones. The only condition is that the amount of gray hair should not exceed 30%.

Highlighting with edging. In this case, use any tone to highlight an area 1–2 centimeters wide along the edge of the hairline. The remaining curls are highlighted using the usual method. This is the optimal solution for cases where gray hair is unevenly distributed over the head and is concentrated in one area: on the back of the head, temples.

Features, which dye to choose

Quite often, women who want to hide gray hair do full coloring with henna or basma. If you believe the reviews, these natural dyes do a good job, but make highlighting difficult. Pigments penetrate deeply into the hair structure, protecting it from further interference. This is also true for strands recently dyed with chemical compounds (especially rich dark colors). That's why The best basis for highlighting gray hair is natural hair. Or wait at least a month after painting.

Attention! You should do the same if you have had a perm.

The choice of shade depends on your color type (taking into account the shade of your skin and eyes) and should be close to your natural color. The permissible deviation is 1–2 tones so that the growing roots are not too noticeable. For highlighting at home, you should use a permanent permanent dye. The main disadvantage is that it contains ammonia, which negatively affects the structure of the hair shafts. But it lasts a long time and covers the “silver” of the hair well. If you are not going to update your hair more often than once every 2-3 months, a long-lasting composition is the best option for any type of highlighting.

If there are not so many white hairs, you can get by with a semi-permanent dye without ammonia. Many cosmetic brands offer such products. A number of manufacturers also produce special tint balms that can be used at the final stage of highlighting gray hair - for tinting.

There are special products for gray hair, covering up to 100% of the head. These are pinkish, ashy, pearlescent shades. Tonics and shampoos help fight yellowness in early whitened strands.

A short haircut is a good solution to hide gray hair, even if it covers more than half of your hair.

It is more convenient to highlight long hair with foil, and for short and medium hair, a cap is preferable. A small amount of “silver” on the curls can be hidden by dyeing with a comb. Also Hairdressers advise rescheduling the procedure if the hair is severely damaged, split, or breaking. Treat them, and then do highlighting.

Highlighting technique

You can apply highlights to hide gray hair in different ways. Choose the one that suits you, taking into account the length of your curls, and also seems more convenient for implementation at home:

Through the cap

1. Comb all curls thoroughly;
2. put on a cap (preferably reusable), secure it well;
3. using a special hairdressing hook or crochet hook, pull strands of the required thickness through the holes;
4. put on a waterproof cape or an old robe. Don't forget gloves.

11. remove the cap and rinse your hair again. It is more convenient to start removing the product from the back of the head.

Using foil

A modern way to highlight gray hair using foil:

2. Having put on a hairdresser's peignoir/old robe/T-shirt, prepare a coloring composition;
3. loosen the hair at the back of your head, form thin strands. You can choose them from large curls in a checkerboard pattern;
4. Apply a thin strip of dye to the matte part of the piece of foil. Take care of the workpieces in advance by cutting strips of the required length and width. On each, make a bend 0.5–1 centimeter wide to maintain a distance from the root zone;
5. place the strand on the foil;
6. paint, moving from edge to top;
7. fold the strip, tucking the edges and bottom. You can instead take a similar piece of foil or film;
8. secure the resulting envelope with a bobby pin;
9. in the same way, process all the strands on the back of the head, then on the temples and crown;
10. At the same time, secure with clips those hairs that you do not dye. This will allow you not to get confused and complete the work consistently;
11. After the required time, rinse off the composition in the same sequence in which you applied it. Unwrap each strand and rinse it on the foil, then move on to the next;
12. After removing all the strips, rinse your hair well;
13. Apply balm/mask to your curls.

With a comb

The method of highlighting gray hair with a comb is simple, but the result can be unpredictable if the strands are colored unevenly. Therefore, during the first procedure, do not change the base color by more than 1-2 tones. You can find out the types of combs for highlighting hair, which one is better and more convenient, on our website.

Sequencing:

1. comb your curls;
2. form several parts, secure each with a hairpin;

5. do not rub wet curls with a towel, but only lightly blot them;
6. try to use curling irons, hair dryers, and straighteners less;

How to get rid of gray hair?

If gray hair only makes men look good, then for women its appearance becomes a real tragedy. To hide age-related changes from strangers, experts recommend beautifully coloring your strands. The best option would be highlighting for gray hair - a fresh, original and rejuvenating solution.

Features of the procedure

Is it possible to highlight gray hair? It is possible, but only if the amount of gray hair does not exceed 40%. This is the only way to get the expected effect - all the white hairs will be hidden behind the total mass of multi-colored hair.

Highlighting on gray hair is performed in four ways:

1. Using a cap is a classic method that is considered somewhat outdated and is used only on short hair. The process is very labor-intensive and quite lengthy - a special rubber cap dotted with many small holes is put on the client’s head. Using a hook, strands are pulled through them, onto which a coloring composition is then applied.

1. Using foil is a more modern method that allows you to color medium and long hair with high quality. In this case, individual curls are smeared with a coloring composition and wrapped in foil.

1. Using a comb - this method is suitable for any length. When using it, paint is applied to the teeth of a comb (they should be quite sparse) and combed from roots to ends.
2. Hand highlighting (“frosting” or “glazing”) is most often used on curly or curly hair (both long and short). With this type of highlighting, the paint is applied in such a way as to emphasize the natural vibrancy of the hair and give it additional volume.

Of course, highlighted hair needs to be constantly tinted. The procedure will need to be repeated no later than in 3-4 months. You shouldn’t delay it any longer - your hair will be untidy.

Advice! If gray hair is actively visible only in one area (the back of the head, temples or forehead), you need to even out the shade. To do this, the problem area is first painted with a base color, and only then highlighted.

Advantages of the method

Those who regularly highlight gray hair have never regretted their decision, because this procedure has several important advantages:

1. Gentle effect - does not affect the roots, is carried out only on individual strands;
2. No age restrictions - suitable for both young girls facing the first manifestations of “growing up” and mature ladies;
3. Versatility - can be performed on hair of any length;
4. Giving hair extra fullness and volume.

Types of highlighting gray hair

Have you decided to change your image and are already rushing to the salon? There they can offer you the following highlighting options for gray hair.

Salt and pepper

The name “salt and pepper” speaks for itself - it represents a smooth transition from light gray (salt) to black (pepper) tone. This is the only right solution for those who have gray hair covering most of their hair. Thanks to the stylish combination of light and dark strands, it will become invisible. This option can be safely used on hair dyed in an ashy tone.

Advice! Salt and pepper looks so unusual that it is happily used not only by mature ladies, but also by middle-aged women who do not yet suffer from a lot of gray hair, but who love to experiment with their appearance.

Classic highlighting

To effectively hide a small amount of gray hair, use classic highlighting. By this we mean uniform coloring of the hair along the entire length. The width of the strands can be varied. But remember one thing - to make your hair look more natural, choose the thinnest strands possible. In this case, the difference between the dyed curls and the base color is almost invisible.

Highlighting with edging

Gray highlighting with edging involves highlighting a zone of 1-2 cm along the marginal hairline. To dye this edging, use dye of any color; the rest of the hair is simply highlighted in the usual way.

Important! When choosing shades for highlighting, it is necessary to take into account the characteristics of the color type (skin + hair + eyes). It is advisable to choose tones that are close to your native color. Then the gray hair growing at the roots will not be so noticeable.

Tips to help you choose the most beautiful highlights for gray or graying hair:

Contraindications to the procedure

There are a number of cases in which highlighting is simply impossible. We can include among them:

1. The use of natural dyes - henna or basma. If you have constantly tinted your hair with these products, changing your color to a different color will be quite problematic. Natural pigments penetrate so deeply into the hair structure that it is almost impossible to remove them from there;
2. Thin, damaged hair - as a result of dyeing, it can break off even in the middle of the length;
3. Pre-dyeing in dark chestnut or black. Most likely, only the root zone will be colored, and the rest of the length will remain unchanged.

There is only one way out here - be patient and wait for your shade to grow, and also get serious about restoring the strands.

Important! If you are thinking about how to do highlighting on gray hair at home, we hasten to give you advice - coloring of completely gray hair can only be done by a good hairdresser. Otherwise, the strands may acquire a yellowish or even red tint.

How to properly care for highlighted curls?

For your hair to look as beautiful as in these photos, it needs to be properly cared for. A list of the most important rules can help you with this.

1. Rule 1. To wash your hair, use cosmetics (shampoos and balms) marked accordingly.
2. Rule 2. Secure their effect with indelible fluid gels. The substances included in their composition smooth out colored hair, give it a bright shine, emphasize contrast and maintain lipid balance.
3. Rule 3. Don’t forget about folk remedies. Once a week, lubricate your hair with any vegetable oil - corn, olive, burdock or sunflower. After 1-1.5 minutes, rinse off the oil mask with shampoo - the curls will become shiny, smooth and manageable.
4. Rule 4. Do not comb wet hair - this will cause it to stretch and become thinner.
5. Rule 5. Limit the use of irons, curlers and other thermal devices.
6. Rule 6. Regularly rinse your hair with chamomile decoction - it will allow the highlights to remain bright and eliminate unwanted yellowness. An alternative would be a special tonic with a small percentage of oxidizing agent (1.5-1.9%). It gently colors the strands and does not harm their structure.
7. Rule 7. Lightened curls, deprived of protection in the form of natural pigments, do not tolerate weather conditions well. To protect them from frost and heat, wear hats and regularly use anti-ultraviolet products.
8. Rule 8. Do not rub your wet head with a towel - give preference to natural drying of the strands. This takes longer, but does not harm their structure.
9. Rule 9. If you cannot do without a hairdryer, direct the air flow along the hair growth. This will allow the scales to close and enhance the gloss effect.
10. Rule 10. Do not resort to highlighting on gray hair ahead of schedule - although this procedure is considered gentle, you should not get carried away.
