Ch 18 Chemical Texture Services

Front 1

Compunds made up of carbon, oxygen, hydrogen, and nitrogen

Back 1

Amino Acids

Front 2

Perms use alkonolamines instead of ammonia, and are popular because of their low odor

Back 2

ammonia-free waves

Front 3

active ingrediient or reducing agent in alkaline permanents

Back 3

ammonium thioglycolate (atg)

Front 4

Oily cream used to protect the skin and scalp during hair relaxing

Back 4

base cream or protective base cream

Front 5

Position of the rod in relation to its base esction, determined by the angle at which the hair is wrapped

Back 5

base control

Front 6

Angle at which the rod is psitioned on the head; also, the directional pattern in which the hair is wrapped.

Back 6

base direction

Front 7

The position of the rod in relation to its base section, and is determined by the angle at which the the hair is wrapped.

Back 7

base placement

Front 8

Relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer

Back 8

base relaxers

Front 9

Subsections of panels into which hair is divided for perm wrapping; one rod is normally placed on each base section.

Back 9

base sections

Front 10

Perm wrap inwhich all the rods within a panel move in the same direction and are positioned on equal-size bases; all base sections are horizontal, with the same length and width as the perm rod

Back 10

basic perm wrap

Front 11

Perm wrap in which one end paper is folded in half over the hair ends like an envelope

Back 11

bookend wrap

Front 12

Perm wrap similar to actual technique of bricklaying; base sections are offset from each other row by row

Back 12

bricklay perm wrap

Front 13

Rearranges the structure of curly hair into a straghter or smoother form

Back 13

chemical hair relaxing

Front 14

Hair services that cause a chemical change that permanently alters he natural wave pattern of the hair

Back 14

Front 15

Perm rods that have a smaller diameter in the center that increases to a large diameter on the ends

Back 15

concave rods

Front 16

middle layer of the hair, located directly beneath the cuticle layer. The cortex is responsible for the incredible strength and elasticity of human hair.

Back 16

Cortex

Front 17

Perms in which the hair strands are wrapped at an angle perpendicular to the perm rod, in overlapping concentric layers

Back 17

Croquignole Perms

Front 18

Perm wrap in which partings and bases radiate throughuot the panels to follow the curvature of the head

Back 18

Curvature Perm Wrap

Front 19

Chemical side bonds that are formed when the sulfur atoms in two adjacent protein chains are joined together. Disulfide bonds can only be broken by chemicals and cannot be broken by heat or water.

Back 19

Disulfide bonds

Front 20

Perm wrap in which one end paper is placed under, and one is placed over, the strand of hair being wrapped.

Back 20

double flat wrap

Front 21

Perm wrap in which two rods are used for one strand of hair, one on top of the other

Back 21

Piggyback

Front 22

Perm activated by an outside heat source, usually a conventiional hood-type dryer

Back 22

Endothermic waves

Front 23

Absorbant papers used to ontrol the ends of the hair when wrapping and winding hair on perm rods

Back 23

end papers

Front 24

Creates Exothermic chemical reaction that heats up the waving solution and speeds up processing

Back 24

Exothermic waves

Front 25

Main active ingredient in true and acid-balanced waving lotions

Back 25

Glyceryl monothriglycolate

Front 26

Base control in which the hair is wrapped at an angle of 90 degrees to its base section and the rod is positioned half off its base section

Back 26

half off base placement

Front 27

Weak physical side bonds that are the result of an attraction between opposite electrical charges; easily broken by water, as in wet setting, or heat, as in thermal styling, and re-form as the hair dries o cools

Back 27

Hydrogen bonds

Front 28

The neutralization of hydroxide relaxers is an acid-alkali neautralization reaction that neutralizes the alkaline residues left in the hair by the hydroxide relaxer and lowers the pH of the hair and scalp. Hydroxide relaxer neautralization does not invovle oxidation or rebuild disulfide bonds.

Back 28

Hydroxide neutralization

Front 29

Very Strong Alkalis with a pH over 13. The hydroxide ion is the active ingredient in all hydroxide relaxers.
