What are the three components of permanent waving?
Waving solution, activator, and neutralizer
Hair services that cause chemical change within the natural wave and curl pattern
Chemical Texture Services
smaller diameter in center and larger diameter on the ends.
Concave rods
Thin, absorbent papers used to control the ends of the hair when wrapping and winding hair onto perm rods
end papers or end wraps
4.5-5.5
Endothermic chemical reaction is one that...
absorbs heat from its surroundings
A colorless liquid with a strong, unpleasant odor, is the most common reducing agent in permanent wave solutions.
Thioglycolic Acid
Equal diameter along entire length
Straight rod
one end paper is placed under and another is placed over the strong of hair being wrapped
double flat wrap
Which perm waves process at room temperature?
cold wave
What is the most common neutralizer?
Thio neutralization
Active ingredient in alkaline perms
Ammonium Thioglycolate (ATG)
Also known as a circle rod
Loop rod
mostly uses only one end paper placed over the top of the strand of hair
single flat wrap
Which type of perm is recommended for extremely porous hair
true acid wave
In permanent waving, most the processing takes place within in
the first 5-10 minutes
Active ingredient in acid perms.
Glyceryl Monothioglycolate (GMTG)
soft bender rod
one end paper folded in half over the hair ends like an envelope
bookend wrap
True acid waves have a pH between
4.5-7.0
When should you perform an elasticity test
before the service
Stops the action of the waving solution and rebuilds the hair into its new curly form.
Thio Neutralization
what is the most common type of rod?
concave rods
What is Stacie's favorite kind of wrap?
Bookend
