Hello, I just joined the forum and have many questions. I have been taking percocet(ENDOCET)for over 2 years, and am very concerned.I am 26 and my hair is starting to thin out, and was wondering if the percocet has anything to do w/ it.It was always a little thin but is now more noticable. Every doctor I ask ( including 2 hair specialists, my physician, and dermatologist) say it does not cause hair loss. So I figured this might be the best way to find out. I have been reading many posts here and it seems very informative. I had some test on everything from a to z. Including thyroid, liver, kidneys, testosterone. Everything seemed average for my age. I also started taking propecia 3 weeks ago and cut down on the percs (from 4 aday to 1 every other day). Can someone help me? Thanks in advance.
