Hi. I am a 28-year old female and I am beginning to notice thinning of hair on the sides. It is not very evident if hair is let loose. The doctor has advised to use Mintop and Bioexidil serum. However, according to reviews online, once I stop using Mintop, I will lose more hair. But, my doctor says that if discontinued post the hair is in Anagen phase, there should not be any issue. please let me know what is the best approach.
