Alopecia thallium is a rare genetic disorder that causes hair loss on the scalp and body. This disease first became known in 2013, when it was discovered in four women from Germany.
Among the characteristic symptoms of the disease are hair loss, increased oiliness of the scalp, partial plucking of hair and changes in hair color. In some cases, patients experience curvature of the nails and changes in the nail plate.
Alopecia thallium can be diagnosed with a biopsy of the skin or hair follicles, which shows the absence of a hair follicle. Sometimes genetic testing may also be needed.
The cause of the disease is still unknown. However, scientists suggest that it is associated with a mutation in the gene that is responsible for regulating hair growth. Some studies also indicate a connection between thallium alopecia and vitamin D deficiency in the body.
There is currently no treatment for this disease. Patients are advised to monitor the condition of their scalp and hair, and also avoid exposure to sunlight.
