Chapter 20: Chemical Texture (Relaxers & Curls)

_________________________________________ is the process of rearranging the structure of curly hair into a straighter or smoother form.

The chemistry of relaxers and permanent waving is:

• exactly the opposite

• exactly the same

What are the three most common types of hair relaxers?

These relaxers use the same ATG that is used in permanent waving but at a higher concentration and a higher pH.

• sodium hydroxide

• Japanese thermal straightners

• thio relaxers

The __________________________________ used with thio relaxers is usually hydrogen peroxide.

This combines the use of a thio relaxer with a flat iron.

• sodium hydroxide straightener

• Japanese thermal straightener

• ammonium thioglycolate straightener

The hydroxide ion is the active ingredient in all ___________________________________ _________________________.

Hair that has been treated with a hydroxide relaxer is unfit for ___________________ ______________________ and will not hold a curl.

Sodium hydroxide relaxers are commonly called _____________ __________________.

An oily substance used to protect the skin and scalp during hair relaxing:
