Wraps
perm wrap in which one end paper is folded in half over the hair ends
bookend
have pH between 9.0 and 9.6, use ammonium thioglycolate as the reducing agent
alkaline waves
perm rods that are equal in diameter along their entire length
straight rods
active ingredient or reducing agent in alkaline permanents
Ammonium thioglycolate
thin, absorbent papers that control the hair’s ends when winding hair on perm rods
end papers
perm wrapping pattern in which all the rods within a panel move in the same direction on equal-sized bases
basic wrap
perm that uses an ingredient other than ATG as the primary reducing agent
thio-free waves
tool that is usually about 12 inches long with a uniform diameter along the rod’s entire length
active ingredient in a no-lye based relaxer
Calcium hydroxide
oily cream used to protect the skin and scalp during hair relaxing process
Base cream
hair is wrapped around the rods vertically until it fills each rod’s length
spiral wrap
thio-based chemical process loosens very curly hair into larger soft curls or waves
soft curl perm
flexible foam rod
soft bender rods
main active ingredient in true acid and acid-balanced waving lotions
Glyceryl monothioglycolate
conditioners with an acidic pH that restore the hair’s natural pH before the final neutralizing shampoo
Normalizing lotions
hair is wrapped on one rod from the scalp to midway down the hair shaft, and another wraps the remaining hair
piggyback
perms that use sulfates, sulfites, and bisulfites as an alternative to ATG
Low pH waves
perm rods that have a smaller diameter in the center increasing to a larger diameter on the ends
concave rods
process by which hydroxide relaxers permanently straighten hair
lanthionization
process that permanently rearranges curly hair’s structure into a straighter or smoother form
hair relaxing
base sections are offset from each other row by row
bricklay
perms with neutral pH
Acid balanced waves
the rod’s position in relation to its base section
Base placement
measurement of a liquid’s thickness or thinness
viscosity
services that cause a chemical change that alters the natural wave pattern of the hair
chemical texture
