Ok so after carefully examining my hair for the past 3 months Ive come to the crushing conclusion that Im thinning in the NW4-5 area. Its diffuse and in relatively early stages. I can still wear my hair in many ways without it being that noticeable. Still its leaning more to the noticeable side and I fear that if I dont do something about it soon, people might start noticing. Anyway at an early stage can taking finasteride be enough. Is it possible to regrow some of the hair ive lost. BTW Im 24 and I think Ive lost about 30% of my original density.
