End paper, or Porous end wrap
What are 3 ways to use end paper when wrapping?
Bookend wrap, single/flat wrap , double wrap
The two layers of hair that are mostly affected by chemical hair services.
Cuticle, and Cortex

Name at least 3 types of rods used in rodding?
Straight, Bender, Concave, Circle / loop rods.
Name 3 types of rodding patterns
Bricklay wrap, Piggy-Back wrap, Curvature wrap, Basic wrap
Describe the characteristics of a Water Wrap vs. Lotion Wrap
Water Wrap: Hair is moistened with water
Lotion Wrap: Waving solution applied, pre-softens hair, "jump starts" processing action
What is the purpose of a Chemical Relaxer?
To relax curly or wavy hair into straighter looking hair.
A Curl Reformation is also known as (3)
Soft curl perm, Jheri curl, or simply a curl.
What is the purpose of a permanent wave?
To chemically restructure natural hair into a different wave pattern. OR To turn straight or wavy hair into a curly form.
What does the hair look like when the wave has reached its peak?
Forms the perfect letter "S".
Chemical texture services involve which two principle actions on the hair?
Chemical and Physical
Are Hydroxide Relaxers and Thio Relaxers compatible with each other? Yes or No
No.. Hydroxide and Thio relaxers are not compatible and crossing over products will result in hair breakage.

What is the purpose of a Curl Reformation?
To restructure very curly hair into a larger curl pattern.
9.0-9.6 pH, contains ATG ammonium thioglycolate, for resistant hair types, fast processing time, produces a strong curl.
Alkaline Perm, (Cold Wave)
pH 7.0 or neutral, process at room temparature, contains ATG and GMTG
Acid-Balanced Waves
Explain the difference between Endothermic and Exothermic
Endothermic Waves= requires perm activation from an outside heat source like a dryer, etc. (external)
Exothermic Waves = perm creates a chemical reaction that heats solution and speeds up processing time (internal/ mixing)
Explain the difference between Base Relaxers and No-Base Relaxers
Base Relaxers = require the application of of a base cream to the entire scalp prior to relaxer application.
No-Base Relaxer = contain a base cream that melts at body temperature and does not require the application of a separate protective base.
What is the purpose of a Chemical Blowout
Partially straightens the hair with the intent that it will be picked out and cut.
pH between 4.5 to 7.0, contains GMTG glyceryl monothioglycolate, produces softer curl, slower processing time, delicate hair types, requires outside / external heat (Endothermic)
True Acid Waves
Contains an oxidizing agent (usually hydrogen peroxide), releases heat when mixed
Exothermic Waves
Process of stopping chemical action, rebuilds the disulfide bonds broken during processing, most common is Hydrogen Peroxide
Neutralizer or Neutralization
A "preliminary strand test" for chemical relaxer services should include what 3 components or purposes.
1. Degree of porosity
2. Degree of elasticity
3. Hair reaction to the chemical and processing time

When doing a curl reformation, you can mix brands and systems when it comes to neutralizer and waving lotions. You do not have to use the manufactures recommended neutralizer with the waving lotion.
True / False?
FALSE!! Always use the manufactures recommended neutralizer with waving lotion. NEVER mix brands or systems.
