Hi Curious,
I know nothing about Sam-e stuff.

But I was a hairdresser for severals years.

A average person hairs grows about a 1/2 inch a month. Does your scalp feel tight? If it does get in their with the balls of your fingers when shampooing. This can help some with circulation.

Also do you color your perm or hair? What texture is your hair? I am asking this because people can get alot of breakage from the bottom. Usually at least the ends of your hair will feel dry.

Hugs, Roz
