Flashcards in 20. Chemical Texture Services Deck (36):
1

Curl re forming

The chemical texture service that loosens overly curly hair or changes tightly curly or coiled hair into loose curls or waves

2

Cortex

The layer of the hair that provides the strength and elasticity of the human hair

3

4.5-5.5

The natural PH of hair

4

Permanent waving

The size of the curl is determined by the sides of the rod

5

Croquignole perm technique

Basic type of wrapping the hair around a perm rod

6

Reduction reaction

Involved either the addition of hydrogen or removal of oxygen

7

Reduction reaction

Involves either the addition of hydrogen or removal of oxygen

8

Cold waves

Most have a PH between 9.0 to 9.6

9

Neutralizer

One of the three separate components of acid waves

10

Endothermic wave

Activated by an outside heat source

11

Permanent wave solution

Should be rinsed from the hair for at least 5 mins

12

Chemical hair relaxing

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

13

Thio relaxers

Usually have a PH Above 10

14

Hydroxide ions

When left in the hair after a relaxer can be neutralized using an acid balanced shampoo

15

Metal hydroxide relaxers

Type of relaxer that contains only one component an is used exactly as it is packaged with no mixing necessary

16

Potassium hydroxide relaxers

often advertised and sold as no mix no lye relaxers

17

Salt bonds

Type of bond that is relatively weak physical side bonds that are the result of an attraction between negative and positive electrical charges

18

Loop rods

Type of rod also know as circle rod on base

19

On base placement

The hair is wrapped at 45 beyond perpendicular to its base section and the rod is positioned on its base

20

Acid balanced waves

Permanent wave that processes at room temp

21

Chemical solutions

Raise the PH of the hair to alkaline state

22

Elasticity test

Should be performed before perming hair

23

Porous hair

Could be damaged by a highly alkaline permanent waving solution

24

GMTG

The primary reducing a gent in the most acid waves has a low PH

25

True acid waves

Have a PH between 4.5 to 7.0

26

Ammonia free waves

Have very little Odor

27

Permanent waving

Most of the processing takes place with in the 1st 5 to 10 mins

28

Safety precaution

Of permanent waving is to examine the scalp before the perm service

29

Extremely curly hair

The twists are the thinnest and weakest section of the hair strands

30

Relaxers

Extremely alkaline and can melt or dissolve hair if used incorrectly

31

Hydroxide relaxers

If a client has been treated with this it means the hair will not hold a curl when applying a thio relaxer

32

Double flat wrap

Is a perm wrap in which one end paper is placed over the strand of hair being wrapped

33

Soft bender rods

Type of rods usually about 12 inch long with a uniform diameter along the entire length of the rod

34

Thioglycolic acid

Common reducing agent

35

Medulla

Innermost layer of the hair

36

Cuvature permanent wrap

The type of wrap that the partings and bases radiate throughout the panels to follow the cube rather of the head
