There are many types of hair loss with different symptoms and causes. Androgenic or androgenetic alopecia is the most common form of hair loss. Hair loss occurs in both men and women, but women experience it less often and later in life, usually in the 6th decade of life. In men, it can occur at any time after puberty. It usually starts gradually in the 2nd decade, and is most intense in the 40s.
There are two types of androgenetic alopecia, depending on which regions are affected:
- Male type usually starts with the reduction of hairline, followed by thinning of hair at the crown and the surrounding areas. It can lead to complete loss of hair, beginning above both temples. It more commonly occurs in men but it can also occur in women.
- Female type occurs extremely rare in men, and hair usually thins on the top of the head and does not lead to complete baldness.
Both men and women often struggle to deal with this form of hair loss.
More types of treatment give hope
The goal of the treatment is to stop progressive hair loss and so prevent the development of alopecia (pattern baldness), and stimulate new hair growth.
- finasteride - the first results of the therapy become visible after 3 months, and growth is evident after 6 months. In case of termination of therapy within 12 months, the newly grown hair starts to fall off. The preparation may be used only by men. The most important side effects are possible reduction of libido and erectile disorders, besides the teratogen! Fortunately, the resulting disorders are transient after treatment discontinuation.
- minoxidil 2% and 5% is applied locally, and it leads to hair re-growth after 4-12 months in 40% of men. The application is permanent. Minoxidil is also used for the treatment of female baldness.
- antiandrogens - They block the androgen receptors so they can be used only in women:
- cyproterone acetate,
