I've been taking Ritalin for over a year and just randomly for no apparent reason, my hair started to fall out too! Luckily I have long thick hair to began with so it wasn't as bas as It could have been. The odd thing about it- It only happended for like one month. I wondered if It could have something to do with the brand of methylphenidate I was taking. I usually go to the same pharmacy every month, however, the month my hair started falling out I actually went to a different drug store and was given methylphenidate from a different manufactor that time. The next month I went back to my normal pharmacy and no more problems. Do yall take name brand adderall or generic?
