I'm really distressed about hairloss I feel lots of gap areas when I apply oil, especially in my crown area. My dad has lost bit hair in the front although not bald in the crown area although my granddad was bald in crown. People say I totally look fine but when I take pictures I see lots of gap upclose. I'm taking iron tabs and multivit. I really don't wanna get bald at as young as 25 what can I do to get thicker and fuller hair. I have seen biotin, finasteride, rogain. But i'm scared of sidedefects if I discontinue. Please help me here.
