not true acid waves, as they have a ph between 7.8 and 8.2 and use glyceryl monthioglycolate(GMTG)as the primary reducing agent acid-balanced waves process at room temperature,do not require the added heat of a hair dryer,process more quickly, and produces firmer curls than true acid waves.
alkaline waves or cold waves)
have a ph between 9.0 and 9.6, use ammonium thioglycolate(ATG)as the reducing agent, and process at room temperature.
compunds made up of carbon,oxygen,hydrogen, and nitrogen.
perms use alkanolamines instead of ammonia, and are popular because of their low odor.
active ingredient or reducing agent in alkaline permanants.
base cream or protective base cream
oily cream used to protect the skin and scalp during hair relaxing.
position on the rod in relation to its base section, determined by the angle at which the hair is wrapped.
the position of the rod in relation to its base section, and is determined by the angle at which the hair is wrapped. rods can be wrapped on base, half off base, or off base.
relaxers that the application of protective base cream to the entire scalp prior tothe application of the relaxer.
subsections of panels into which hair is divided for perm wrapping;one rod is normally placed on each base section.
basic perm wrap
perm wrap in which all the rods within the panel move in the same direction and are positioned on equal-size bases; all base sections are horizontal, with the same length and width as the perm rod.
perm wrap in which one end paper is folded in half over the hair ends like an envelope.
bricklay perm wrap
perm wrap similar to actual tecnique of bricklaying; base sections are offset from eachother row by row.
chemical hair relaxing
rearranges the structure of curly hair into a straighter or smoother form.
chemical texture services
hair services that cause a chemical change that permanently alters the natural wave pattern of the hair.
perm rods that have a smaller diameter in the center that increases to a larger diameter on the ends.
middle layer of the hair, located directly beneath the cuticle layer. The cortex is responsible for the incredible strength and elasticity of human hair.
perms in which the hair strands are wrapped at an angle perpendicular to the perm rod,in overlapping concentric layers.
curvature perm wrap
perm wrap in which partings and bases radiate throughout the panels to follow the curvature of the head
chemical side bonds that are formed when the sulfur atoms in two adjacent protein chains are joined together.
double flat wrap
perm wrap in which one end paper is placed under,and one is placed over, the strand
