An oily barrier to protect the scalp before performing a chemical service
base cream
what are the protein building blocks of hair
amino acids
thickness of liquids and how it effects the flow
viscosity
type of relaxer that requires a base cream
base relaxer
stops the waving process of a permanent wave, rebuilding the bonds of the hair into it's new form
neutralizer
to chemically alter naturally curly/wavy hair in to a straighter form
chemical relaxing
when two substances can be mixed with eachother
miscible
when two substances cannot mix with eachother
immiscible
this kind of side bond can only be broken by a chemical
disulfide bonds
mixture of two or more types of matter that are blended but not chemically joined
physical mixture
strongest type of relaxer
sodium hydroxide
combination of ammonia and thioglycolic acid that creates a reducing agent
ammonium thioglycolate
these bonds connect polypeptide chains side by side
crossbond or side bond
in a physical mixture, two or more types of matter are ______________ but not chemically joined
blended
What is the scale that measures acidity and alkalinity of liquids?
Potential Hydrogen (pH)
the hair's ability absorb liquids
porosity
helps remove chemicals remaining in the hair after a chemical relaxer and restores hair to it's normal pH
neutralizing shampoo
a mixture of two or more types of matter that are blended but not chemically joined
physical mixture
spiraling chains of amino acids joined by a peptide bond is...
polypeptide chain
these bonds connect to amino acids that form polypeptide chains
peptide bonds
used to neutralize any remaining alkaline residue left by a hydroxide relaxer. (helps to restore the pH)
hydroxide neutralization
how do you drape your client when servicing a chemical texturizing service?
1. Sanek
2. Towel
3. Cape
4. Towel
combining a thio relaxer and a thio permanent wave in a two step process...
soft curl reformation
no lye relaxer with ammonia used to first relax then rearrange into a larger curl pattern
thioglycolate relaxer
weak side bonds affected by a change in the pH of the hair
salt bonds
