Q

Acid-Balanced Waves

A

perms with 7.0 or neutral pH; because of their higher pH, they do not require the added heat of a hairdryer, process more quickly, and produce firmer curls than true acid waves; always follow the manufacturer’s instructions when using

Alkaline Waves

A

also known as cold waves; have pH between 9.0 and 9.6, use ammonium thioglycolate (ATG) as the reducing agent, and process without the addition of heat according to the manufacturer’s instructions

Q

End Papers

A

also known as end wraps or perm papers; thin, absorbent papers that control the hair’s ends when winding hair on perm rods

21
Q

Exothermic Waves

A

create an exothermic chemical reaction that heats up the waving solution and speeds up processing

22
Q

Glyceryl Monothioglycolate (GMTG)

A

main active ingredient in true acid and acid-balanced waving lotions

23
Q

Half Off-Base Placement

A

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

24
Q

Hydroxide Neutralization

A

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

25
Q

Hydroxide Relaxers

A

used to relax the hair; contains a very strong alkali with a pH over 13; the hydroxide ion is the active ingredient in all hydroxide relaxers

26
Q

Keratin-Based Smoothing Treatments

A

also called Brazilian keratin treatments, semipermanent treatment that smooths curly and wavy hair textures and eliminates frizz for up to 12 weeks

27
Q

Lanthionization

A

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

28
Q

Loop Rod

A

also known as circle rod; tool that is usually about 12 inches (30.5 cm) long with a uniform diameter along the rod’s entire length

29
Q

Low-pH Waves

A

perms that use sulfates, sulfites, and bisulfites as an alternative to ammonium thioglycolate

30
Q

Lye Relaxers

A

also known as sodium hydroxide or caustic soda; used to break the disulfide bonds and loosen curls

31
Q

Metal Hydroxide Relaxers

A

ionic compounds formed by a metal (sodium, potassium, or lithium) that is combined with oxygen and hydrogen

32
Q

No-Base Relaxers

A

relaxers that do not require application of a protective base cream

33
Q

Normalizing Lotion

A

conditioners with an acidic pH that restore the hair’s natural pH before the final neutralizing shampoo for hydroxide relaxers

34
Q

Off-Base Placement

A

base control in which the hair is wrapped at 45 degrees below base section’s center so the rod is positioned completely off its base

35
Q

On-Base Placement

A

base control in which the hair is wrapped at a 45-degree angle beyond perpendicular to its base section, and the rod is positioned on its base

36
Q

Panels

A

perm sections; size, shape, and direction vary based on wrapping patterns

37
Q

Partial Perm

A

permanent waves that curl only specific areas of the head

38
Q

Permanent Waving

A

adds wave or curl to the hair; also used to loosen curls; two-step process whereby the hair undergoes 1) a physical change caused by wrapping the hair on perm rods the hair then undergoes and 2) a chemical change caused by the application of permanent waving solution and neutralizer

39
Q

Relaxer Retouch

A

application for hair that has received a chemical relaxer service

40
Q

Single Flat Wrap

A

perm wrap that is similar to double flat wrap but uses only one end paper, placed over the top of the base panel of hair

41
Q

Sodium Hydroxide Relaxers

A

also known as lye relaxer or caustic soda; used to break the disulfide bonds and loosen curls

42
Q

Soft Bender Rods

A

also known as flexible foam rod; a tool about 12 inches (30.5 cm) long with a uniform diameter along the rod’s entire length

43
Q

Soft Curl Permanent

A

also called chemical curl reformation service; this thio-based chemical process loosens very curly hair into larger soft curls or waves

44
Q

Spiral Perms

A

utilize the spiral wrap technique in which hair is wrapped around the rods vertically until it fills the length of each rod like stripes on a candy; as long as the angle remains constant, any overlap will be uniform along the length of the rod and the strand of hair

45
Q

Spiral Wrap Technique

A

used in spiral perms; the hair is wrapped around the rods vertically until it fills each rod’s length like stripes on a candy cane

46
Q

Straight Rods

A

perm rods that are equal in diameter along their entire length or curling area

47
Q

Thio-Free Waves

A

perm that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine

48
Q

Thio Neutralization

A

relies on an oxidation process to stop the action of the relaxer solution and rebuild the hair into its new form

49
Q

Thio Relaxers

A

use reduction and oxidation to break the disulfide bonds and then reform them to a more relaxed hair texture, use the same ammonium thioglycolate (ATG) that is used in permanent waving, but at a higher concentration and a higher pH (above 10)

50
Q

True Acid Waves

A

have a pH between 4.5 and 7.0 and require heat to process; they process more slowly than alkaline waves and do not usually produce as firm a curl as alkaline waves

51
Q

Virgin Relaxer

A

application used for hair that has not had a previous chemical relaxer service
