Hair relaxer is a type of chemical used to straighten hair permanently.

It’s used by people, usually women, who want to straighten their naturally curly hair without having to use hot combs or pressing irons.

It may also be used by women who are seeking a means of thinning out hair that is very thick or making it more manageable.

Chemical relaxers, which either contain lye or a no-lye chemical formula, work to soften the hair and change its natural structure to a straighter form.
