I was on accutane for two 6 month stints, and my hairline rapidly receding from a NW0.5 (which I think I was naturally) to NW2.5! I've wasted a lot of money on snake oils and gimmicks, and I wouldn't pretend to know what the exact science is behind some treatments, but the main thing I took away...
no way mate! your hairline looks okay at this point. I didn't like the idea of counteracting the effects of a strong drug with another strong drug (propecia), plus I read a lot of male pattern baldness treatments don't really work for accutane sufferers. I accelerated to a NW2.5 within 6 months of coming off...
