Q

Q

Also known as piggyback wrap; a wrap technique whereby extra-long hair is wrapped on one rod from the scalp to midway down the hair shaft, and another rod is used to wrap the remaining hair strand in the same direction.

A

Double-rod wrap

23
Q

Also known as end wraps;absorment papers used to control the ends of the hair when wrapping and winding hair on perm rods.

A

End papers

24
Q

Perm activated by an outside heat source, usually a conventional hood-type hair dryer.

A

Endothermic waves

25
Q

Create an exothermic chemical reaction that heats up the waving solution and speed up processing.

A

Exothermic waves

26
Q

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

A

Glyceryl monothioglycolate

27
Q

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

A

Half off-base placement

28
Q

An acid-alkali neutralization reaction that neutralizes (deactivates) the alkaline residues left in the hair by a hydroxide relaxer and lowers the Ph of the hair and scalp; hydroxide relaxer neutralization does not involve oxidation or rebuild disulfide bonds.

A

30
Q

31
Q

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

A

Q

Also known as circle rod; tool that is usually about 12 inches long with a uniform diameter along the entire length of the rod.

A

Peptide bonds

40
Q

A two-step process whereby the hair undergoes a physical change caused by wrapping the hair on the perm rods; the hair then undergoes a chemical change caused by the application of permanent waving solution and neutralizer.

A

A

Polypeptide chains

42
Q

45
Q

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

A

Soft curl permanent

46
Q

Hair is wrapped at an angle other than perpendicular to the length of the rod, which causes the hair to spiral along the length of the rod, similar to the strips on a candy cane.

A

Straight rods

48
Q

The most common reducing agent in permanent wave solutions.

49
Q

Stops the action of a permanent wave solution and rebuilds the hair in its new curly from.

50
Q

Use the same ammonium thioglycolate that is used in permanent waving, but at a higher concentration and a higher Ph.

A

Thio relaxer’s

51
Q

Have a Ph between 4.5 and 7.0 and require heat to process; they process more slowly than alkaline waves, and they do not usually produce as firm a curl as alkaline waves.
