oily cream used to protect the skin and scalp during hair relaxing
relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer
CHEMICAL HAIR RELAXING
process or service that rearranges the structure of curly hair into a straighter or smoother form
an acid alkali neutralizaton reaction that neutralizes the alkaline residues left in the hair by a hydroxide relaxer and lowers the ph of the hair and scalp, hydroxide relaxer neutralization does not involve oxidation or rebuild disulfide bonds
very strong alkalis with a ph over 13; the hydroxide ion is the active ingredient in all hydroxide relaxers
process by which hydroxide relaxers permanently straighten hair, they remove a sulfur atom from a disulfide bond and convert it into a lanthionine bond.
METAL HYDROXIDE RELAXERS
ionic compounds formed by a metal (sodium, potassium or lithium ) which is combined with oxygen and hydrogen.
NO BASE RELAXERS
relaxers that do not require application of a protective base cream
conditioners with an acidic ph that restore the hairs natural ph after a hydroxide relaxer and prior to shampooing
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.
use the same ammonium thioglycolate that is used in permanent waving but at a higher concentration and a higher ph (above 10)
the measurement of thickness or thinness of a liquid that affects how the fluid flows
