I'm a 26 y/o male. Noticed hair loss early and my dermatologist told my I should use 5% minoxidil or finasteride. Started using %5 minoxidil 16 months ago every night, focusing on my right temple area to decent results. This past month my right temple area started thinning extremely fast all of a sudden and was wondering: Is it a shedding phase or should I be worried? Thanks P.S. The attached image shows the affected area, will post a better one later.
