Milady Sophomore Final Exam
The process of permanently altering the natural wave pattern of hair is described as
Chemical Texture Services
The two methods of wrapping hair around a perm tool are
Spiral & Croqinole
Once in the cortex the waving solution breaks the disulfide bonds through a chemical
reaction called
Reduction
In the reconstructing process, coarse, resistant hair with a strong compact cuticle requires
a solution that is
Highly alkaline
An acid with a low pH that is the primary reducing agent in acid waves is
Glycerol monothioglycolate
Waves that are activated from an outside heat source are considered
Endothermic
The process of stopping the action of permanent waves and hardening the hair into its new
form is
Neutralization
In permanent waving the size of the curl is determined by the
Size of the rod
The most common reducing agents used are
Thioglycolate acid
The wrapping technique that provides the most control over hair ends and keeps them
evenly distributed over the entire length of the rod is a
Double flat wrap
Hair that has too many disulfide bonds broken and will not hold a firm curl is considered
Over processed
, The main active ingredient or reducing agent in alkaline permanent waves is
Ammonium thioglycolate
A correct permanent wave service alters only what bonds
Disulfide/"side bonds"
The key to ensuring complete penetration of permanent waves is
Saturation of the cortex
Most alkaline permanent waves have a pH between
9.0 and 9.6
In permanent waving the shape and type of curl are determined by the shape and type of
rod and the
Wrapping method
Most acid waves have a pH value between
7.8 and 8.2
Acid permanent waves have 3 components
Waving lotion, activator, and neutralizer
Endothermic perms are activated by an
Outside heat source
The process of stopping the action of permanent waving and hardening the hair in to a new
form is
Neutralization
Before applying a neutralizer to the hair
Rinse for 5 minutes
Chains that are formed by peptide bonds that are linked together are
Peptide
In permanent waving the reduction reaction is due to the addition of
Hydrogen
Chemical services performed on overly porous hair requires a solution that is
Low pH
Waves that create a chemical reaction that heats up the solution and speeds up processing
is
Exothermic
