perms use alkanolamines instead of ammonia and have a low odor
Term
ammonium thioglycolate
Definition

active ingredient or reducing agent in alkaline permanents

 

Term
base control
Definition
position of the rod in relation to its base section determined by the angle at which the hair was wrapped
Term
base cream or protective base cream
Definition
oily cream used to protect the skin and scalp during hair relaxing
Term
base direction
Definition
angle at which the rod is posistioned on the head,also the direction in which the hair is wrapped
Term
base placement
Definition
the position of the rod in relation to its base section, on base half off base and off base
Term
base relaxers
Definition
relaxers that require the application of protective base cream to the entire scalp prior to the relaxer
Term
base sections
Definition
subsections of panels into which the hair is divided for perm wrapping
Term
basic perm wrap
Definition
perm wrap in which all the rods within a panel move in the same direction and are positioned on equal size bases
Term
bookend wrap
