Front 1

Acid-balanced waves

Back 1

Permanent waves that have a 7.0 or neutral pH that processes at room temperature, processes more quickly and produce firmer curls than true acid waves.

Front 2

Alkaline waves

Back 2

Aka cold waves; they have a pH between 9.0 and 9.6, use ammonium thioglycolate (ATG) as the reducing agent, processes at room temperature.

Front 3

Base relaxers

Back 3

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

Front 4

Concave rods

Back 4

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

Front 5

Croquignole perm wrap

Back 5

Perm where the hair strands are wrapped from the ends to the scalp in overlapping concentric layers.

Front 6

Disulfide bonds

Back 6

Strong chemical bonds formed when the sulfur atoms on two adjacent protein chains are joined together.

Front 7

Endothermic waves

Back 7

Perm activates by an outside heat source.

Front 8

Exothermic waves

Back 8

Create an exothermic chemical reaction that heats up the waving solution and speeds up the process.

Front 9

Glyceryl monothioglycolate (GMTG)

Back 9

Main active ingredient in true acid and Acid-balanced waving lotions.

Front 10

Hydroxide relaxers

Back 10

Very strong alkalis with a pH over 13.

Front 11

Lanthionization

Back 11

Process by which hydroxide relaxers permanently straighten hair; they remove a sulfur atom from a disulfide bond and convert it into a lanthionine bond.

Front 12

Low pH waves

Back 12

Perms that use sulfates, sulfites, and bisulfites as an alternative to ATG.

Front 13

Peptide bond

Back 13

Aka end bonds; chemical bonds that join amino acids together, end to end in long chains to form polypeptide bonds.

Front 14

Soft curl perm

Back 14

A thio based chemical service that reformats curly and wavy hair into looser and larger curls and waves.

Front 15

True acid waves

Back 15

Have a pH between 4.5 and 7.0 and require heat to process.

Front 16

Viscosity

Back 16

The measurement of the thickness or thinness of a liquid that affects how the fluid flows.

Front 17

Ammonium thioglycolate

Back 17

The main active ingredient or reducing agent in alkaline perms?

Front 18

Glycerol monothioglycolate

Back 18

The main ingredient in Acid-balanced waving lotions?

Front 19

Expand the hair

Back 19

The action of waving lotion is to?

Front 20

Little or no elasticity

Back 20

If hair breaks under slight strain it has?

Front 21

Amino acids

Back 21

Keratin proteins are made of long chains of _________ linked together end-to-end like beads.

Front 22

Acid-balanced

Back 22

Waves that process more quickly and produce firmer curls than true acid waves are considered to be?

Front 23

Disulfide bonds

Back 23

Bonds that are formed when the sulfur atoms in two adjacent polypeptide chains are joined together.

Front 24

Waving lotion

Back 24

The chemical action of ________ breaks the disulfide bonds and softens the hair.

Front 25

Hydrogen, salt, and disulfide

Back 25

Name the 3 types of side bonds.

Front 26

4.5 to 5.5

Back 26

What is the natural pH of hair?
