Relaxers
Relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer
base relaxers
Perms that uses sulfates, sulfites, and bisulfites as an alternative to ammonium thioglycolate
low-pH waves
The measurement of the thickness or thinness of a liquid that affects how the fluid flows
viscosity
Wrapping techniques that uses zigzag partings to divide base areas
weave technique
Base control in which the hair is wrapped at an angle of 90 degree or perpendicular to its base section
half off- base placement
Very strong alkalis with a pH over 13
hydroxide relaxers
A two step process whereby the hair udergoes a physical change caused by wrapping the hair on perm rods; the hair then undergoes a chemical change caused by the application of permanent waving solution and neutralizer
permanent waving
Weak physical side bonds that are also the result of an attraction between opposite electrical charges
hydrogen bonds
perm rods that are equal in diameter along their entire length or curling area
straight rods
Base control in which the hair is wrapped at a 45 degree below the center of the base section
off- base placement
Ionic compounds formed by a metal which is combined with oxygen and hydrogen
metal hydroxide relaxers
A thio based chemical service that reformats curly and wavy hair into looser and larger curls and waves
soft curl permanent
Long coiled polypeptide chains
keratin proteins
Process by which hydrogen relaxers permanently straighten hair
lanthionization
Base control in which the hair is wrapped at a 45 degree angle beyond perpendicular to its base section
on-base placement
Relaxers that do not require application of a protective base cream
no-base relaxers
Perms that uses an ingredient other than ATG as the primary reducing agent, such as cysteamine or mercaptamine
thio- free waves
Also known as circle rod; tool that is usually about 12 inches long with a uniform diameter along the entire length of the rod
loop rod
Also known as end bonds; chemical bonds that join amino acids together
peptide bonds
Hair that 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
Spiral perm wrap
Use the same ammonium thioglycolate that is used in permanent waving
thio relaxers
Have a pH between 4.5 and 7.0 and require heat to process; they process more slowly than alkaline waves
true acid waves
Conditioners with an acidic pH that restore the hair's natural pH before the final neutralizing shampoo
normalizing lotions
Long chains of amino acids joined together by peptide bonds
polypeptide chains
Perm wrap that is similar to double flat wrap but uses only one end paper
single flat wrap
