My dermatologist said that it is stress-induced and also can have genetic component. I asked my parents and my mom told me that after she got pregnant with my youngest sister, she had extreme hair loss also and had a bald patch like mine so I guess it's genetic and stress-induced for me. I had weekly steroid injections with my dermatologist and she gave me several medicines to take home - Kairfoll shampoo, Kairfoll serum and Hair Grower solution.
This is my bald patch after 1 month of treatment:
After 5 months, this is a photo of my scalp:
Thanks to my dermatologist, Dr. Margaret Corcoran, for treating my 'Alopecia Areata.' Now I can have my hair down again and not be embarrassed about showing a bald patch when the wind blows it in the wrong direction. LOL! ;)
