What are relaxers made of?

Answer 1

The main ingredient in a Sodium Hydroxide relaxer is Lye. A good relaxer for a sensitive scalp is Guandine which is a Hydrogen relaxer, and a Thio relaxer, which will remove some of the curl, but not completely relax the hair.

Answer 2

It depends on the relaxer. Some are made of lye, others of a chemical called sodium hydroxide. All relaxers have strong chemicals in them and should not be attempted to used by anyone but a professional to prevent breakage, hair loss, skin burns, or even blindness.
