Define Glyceryl Monothioglycolate (GMTG)
the main active ingredient in true acid waves
Define
Guanidine Hydroxide
relaxer requiring the mixing of two products; advertised as ‘no-lye’ for
sensitive skin
Define
Hydrogen Bonds
physical side bond (cross bond) easily broken by water or heat; reforms when hair cools and/or dries
Define
Hydroxide Relaxer
relaxers with a high alkaline (pH) content; available in varying formulations
Define
Hydroxide Neutralization
also called an acid / alkali neutralization reaction; it neutralizes any remaining alkaline residue left by the hydroxide relaxer and helps

substance that has mass and occupies space; it has physical and chemical properties and exists either as a solid, liquid or gas
Define
Miscible
when a substance is able to be mixed with another substance
Define
Neutralizer
chemical solution that stops the waving process of a permanent wave; rebuilds the bonds into their new form
Define
Neutralizing
also known as Rebonding, is chemically restoring disulfide bonds to harden into a new shape
Define
Neutralizing Shampoo
used to help to remove any remaining chemicals left in the hair after a chemical relaxer and to restore hair to normal acidic pH
Define
New Growth
