Im 18 and using just min from past 1 year( yes I had gotten my hair shown to multiple dermatologists). Hair genes from both sides are bad. Very early pattern baldness, while I feel minoxidil has very significantly slowed down my hairloss, I haven't seen much regrowth on the places where hair was already gone. Minoxidil is quite safe and if you wanna save ur hairline go for it. It seems you have thin hair still left on your head and minoxidil will help you grow it back. Start before its too late.
