chemical texture

chemical texture services

the process of chemically altering the natural wave pattern of hair is

0-14

The range of numbers used in the pH scale is:

soften and swell the shaft

Chemical hair texturizers temporarily raise the pH of the hair in order to:

highly alkaline

In the restructuring process, coarse, resistant hair with a strong compact cuticle requires a chemical solution

disulfide bonds

Chemical side bonds formed when two sulfur-type chains are joined together are:

dried

Hydrogen bonds are easily broken by water or heat and are re-formed when the hair is:

wrapping method

In permanent waving, the shape and type of curl are determined by the shape and type of rod and the:

straight rods

Rods that are equal in diameter along their entire length or curling area are:

double flat wrap

The wrapping technique that provides the most control over hair ends is the:

panels

All perm wraps begin by sectioning the hair into:

base sections

In permanent waving, panels of hair aré divided into smaller subsections called:

base direction

The angle at which a permanent wave rod is positioned on the head is referred to as:

ends to scalp

In the croquignole method of wrapping, the hair is wound from

reduction

Once in the cortex, the waving solution breaks the disulfide bonds through a chemical reaction called

hydrogen

b. normalization

In permanent waving, the reduction reaction is due to the addition of:

thioglycolic acids

The most common reducing agents used are

ammonium thigolycolate

The active ingredient or reducing agent in alkaline permanent waves is

9.0- 9.6

Most alkaline permanent waves have a pH between:

glyceryl monothioglycolate

The main active ingredient in true acid and acid-balanced waving lotions is:

activator

All acid waves have three components consisting of the permanent waving lotion, neutralizer, and

7.8 and 8.2

Most acid waves used in salons have a pH value between:

processing

Exothermic waves create a chemical reaction that heats the waving solution and speeds up:

endothermic

Waves that are activated from an outside heat source are considered:

thio neutralization

The process that stops the action of permanent wave solution and rebuilds the hair into its new form is:

bricklay

Base sections are offset from each other row by row, to prevent noticeable splits, in which wrapping pattern?

piggyback

The double-rod wrap technique is also called the:

chemical hair relaxing

The process of rearranging the basic structure of curly hair into a straighter or smoother form

hydrogen ion

The active ingredient in all hydroxide relaxers is the:

lanthione bond

Hydroxide relaxers remove a sulfur atom from a disulfide bond, converting it into a(n):

metal hydroxide relaxers

Relaxers that contain only one component and are used without mixing are:

lye relaxers

Sodium hydroxide relaxers are commonly called

potassium hydroxide relaxers

Relaxers are often marketed and sold as no mix-no lye relaxers are:

guanidine hydroxide relaxers

Relaxers that contain two components and must be mixed immediately prior to use are

no base relaxers

Hydroxide relaxers that do not require the application of a protective base are

hydroxide

The difference in the strength of most chemical hair relaxers is determined by the concentration of

insufficiently relaxed

During a relaxer strand test, hair that is pressed to the scalp and continues to curl is

back of head

The application for chemical relaxers should be started in the most resistant area, usually the

normalizing lotion

Conditioner with an acidic pH that restores the hair's natural pH after a hydroxide relaxer is

soft curl permanent

A combination of a thio relaxer and a thio permanent wrapped on large rods is a

thio relaxers

Hair that is treated with hydroxide relaxers must not be treated with
