If a person realizes that he or she is losing a lot of hair for a long time, he or she should first look for the cause in a possible iron and ferritin deficiency or a lack of folic acid or a thyroid dysfunction.

In order to make the best possible evaluation of the problem, the dermatologist after taking a complete history will ask for a complete blood count and will also ask for the necessary tests, such as a complete blood count that will include a test for iron, ferritin, folate, T3, T4, TSH, anti-thyroid antibodies.

Women usually have to undergo additional hormonal tests. In addition, but also as a follow-up to the treatment recommended by the dermatologist, we can do more specific tests. The hair chart, which determines the percentage of the different hairs (anagen, catagen, telogen and dystrophic) helps us mainly in monitoring the progression of the disease after treatment.
