I was on Zoloft for a few years and a lot of pain meds, and they definitely affected my hair. It got a lot straighter and much dryer. I don't take nearly so many pain meds now, and after a month on the cg method, It is only just getting back to curly. I used to be 3a before, and my hair is now 2c/3a, so I am much happier with it. I just didn't know what to do with straightish hair, and I hated it, so it always ended up in a ponytail.
