Whats Your Type?
Hair that has been bleached, colored, permed, or relaxed.
What is chemically treated?
Measures the acidity or alkalinity of a substance by measuring the quantity of hydrogen ions it contains.
What it the pH scale?
Tough exterior layer of hair that protects it from damage.
What is the cuticle layer?
Has a pH of at least 13 and is the main reducing agent in all hydroxide relaxers.
What is the hydroxide ion?
Never preform a chemical service if these are present on the scalp.
What are abrasions?
Refers to the number of hair strands per Sq. In. on the scalp.
What is hair density?
Hair services that cause a chemical change in the hairs natural curl pattern.
What are Chemical texture services?
Responsible for the incredible strength and elasticity of human hair.
What is the cortex?
The measurement of thickness or thinness of a liquid that affects how the fluid flows.
What is viscosity?
Never preform this service before a relaxing treatment.
What is a shampoo?
Used to describe the hairs ability to stretch and return to its natural shape.
What is porosity?
Compounds made up of carbon. oxygen, hydrogen, nitrogen, and sulfur.
What are amino acids?
Innermost layer of the hair often called the pith or core.
What is the medulla?
Relaxers that are neutralized by an oxidizing agent such as hydrogen peroxide.
What are thio relaxers?
An allergic reaction caused by repeated exposures to chemicals while working in the salon.
What is contact dermatitis?
Refers to the hairs ability to absorb moisture.
What is porosity?
Also known as end bonds, Chemical bonds that join amino acids end to end in long chains.
What are peptide bonds?
Weak physical side bond that is a result of an attraction between opposite electrical charges and is broken by changes in pH.
What are salt bonds?
Combines the use of a thio relaxer with a flat iron.
What are Japanese straightening systems?
Recommended by the manufacturer to determine weather or not it is safe to preform a texture service on a clients hair.
What is a preliminary test strand/curl?
Classifies hair as straight, wavy, curly, or extremely curly.
What is wave pattern?
Long chains of amino acids joined together by peptide bonds.
What are polypeptide chains?
Weak physical side bonds broken by water and heat.
What are hydrogen bonds?
Removal of a sulfur atom from the hair; the process by which hydroxide relaxers permanently straighten hair.
What is lanthionization?
Over lapping of relaxers or preforming a Thio relaxer over a hydroxide relaxer will cause this.
What is extreme breakage?
