hi Hi, bootsie, I remember you from another forum. If I remember correctly you were losing hair after using retin a, did that ever stop? i am also shedding hair after using topical retin a, and have been shedding for the last 18 months. I have a lot of regrowth but the new growth also falls out. i have been to many doctors and even though they say it is not due to using retin a, i know it is.
