I seriously doubt I'll switch unless they change the formula.
This is one of the few relaxers on the market that dosen't turn my scalp in into raw meat and dosen't make my hair break like crazy. (lye does this to me, and its just not ever pretty)
The only other no-lye that I used was At One (who seems have done something with their formula) which was ok even though it burned but not really bad.
Phyto has never burned my head. To me that says a heck of a lot. I've never had hard hair or lifeless hair, or a ton of hair in the sink while washing it out either.
in fact, like a lot of the ladies have said, the difference between the phyto hair and the other relaxed hair is really significant!
So its a little expensive, but,I may as well get the best for the health of my hair and scalp.
