Types of Hydroxide Relaxers

The process of rearranging the basic structure of extremely curly hair into a straight form is called:

• thermal hair relaxing

• chemical hair waving

• chemical hair relaxing

• permanent waving

Chemical hair relaxing is very similar to:

• permanent haircoloring

• permanent waving

• hair pressing

• thermal waving

Most relaxers contain the same ingredients used in:

• permanent haircolors

• temporary haircolors

• depilatories

• epilators

Hydroxide relaxers remove one atom of sulfur from a disulfide bond and convert it into a Lanthionine bond in a process called:

• reduction

• neutralization

• lanthionization

• oxidation

The disulfide bonds that are broken by hydroxide relaxers:

• can never be re-formed

• are re-formed by lanthionization

• are changed into hydrogen bonds

• are re-formed by neutralizer

The neutralization of hydroxide relaxers involves the use of:

• oxidizing neutralizer

• acid-balanced shampoo

• high -pH shampoo

• hydrogen peroxide

Sodium hydroxide relaxers are commonly called:

• no-lye relaxers

• lye relaxers

• no-mix no-lye relaxers

• low-pH relaxers

A chemical relaxer that straightens the hair completely but with much less scalp irritation than other hydroxide relaxers is:

• guanidine hydroxide relaxer

• sodium hydroxide relaxer

• lithium hydroxide relaxer

• low-pH relaxer

Chemical relaxers marketed as mild alternative relaxers are:

• guanidine hydroxide relaxer

• sodium hydroxide relaxer

• lithium hydroxide relaxer

• sulfites

Mild strength relaxers are recommended for fine, damaged, or:

• medium - curly hair

• medium - texture hair

• color - treated hair

• coarse, extremely curly hair
