Deck 2 Flashcards
What are metal hydroxide relaxers?
Ionic compounds formed by a metal (sodium, potassium, or lithium) which is combined with oxygen and hydrogen.
What are no-base relaxers?
Relaxers that do not require application of a protective base cream.
What are normalizing lotions?
Conditioners with an acidic pH that restore the hair’s natural pH after a hydroxide relaxer and prior to shampooing.
What is off-base placement?
Base control in which the hair is wrapped at 45 degrees below the center of the base section, so the rod is positioned completely off its base.
What is on-base placement?
Base control in which the hair is wrapped at a 45-degree angle beyond perpendicular to its base section, and the rod is positioned on its base.
What are peptide bonds?
Also known as end bonds; chemical bonds that join amino acids together, end to end in long chains, to form polypeptide chains.
What is permanent waving?
A two-step process whereby the hair undergoes a physical change caused by wrapping the hair on perm rods, and then the hair undergoes a chemical change caused by the application of permanent waving solution and neutralizer.
What are polypeptide chains?
Long chains of amino acids joined together by peptide bonds.
What is a single flat wrap?
Perm wrap that is similar to double flat wrap but uses only one end paper, placed over the top of the strand of hair being wrapped.
What are soft bender rods?
Tool about 12-inches long with a uniform diameter along the entire length.
What is a soft curl permanent?
Combination of a thio relaxer and a thio permanent that is wrapped on large rods to make existing curl larger and looser.
What is a Spiral perm wrap?
Hair is wrapped at an angle other than perpendicular to the length of the rod, which causes the hair to spiral along the length of the rod, similar to the stripes on a candy cane.
What are straight rods?
Perm rods that are equal in diameter along their entire length or curling area.
What is thio neutralization?
Stops the action of a permanent wave solution and rebuilds the hair in its new curly form.
What are thio relaxers?
Use the same ammonium thioglycolate (ATG) that is used in permanent waving, but at a higher concentration and a higher pH (above 10).
