I saw some of your pictures of triangular alopecia and it seems to be what I’m experiencing except that it is not congenital and I am a 53 years old. Could it be menopause? Is there is anything I could do about it?
Triangular alopecia is not related to menopause. Triangular alopecia is an entity in and of itself, which both men and women may get and could appear almost any time, but usually is congenital. It can be treated with a hair transplant surgery very successfully.
Triangular alopecia has many appearances, but the common thread is that the hair loss is on the front/side of the scalp. These pictures from Google Image Search give some good examples of the diversity of its presentation.
