I've started to take accutane when 15 years old, i had a very severe acne and I took it for 3 years in more or less high doses and with some pauses. I've had general hairloss on the top of my head after a few months, the doctor said it would stop and it would also regrow, but we paused the treatment and it stopped and so we started the treatment again and it began again, but the doctor said we couldn't stop each time and that it will regrow. A few months later my hair was so thin that you could see the skin of my head, we stopped again and the hairloss also stopped but we didn't wait for something to grow because acne was back, so to make it short accutane had me lose practically all of my hair on the top of my head from front to back and when I stopped the treatment nothing ever grew back. The doctor said that in that case it was not related to accutane but that my genes made this happen but I'm convinced it accutane which had me become bald at only 18 years.
