Relaxers
Relaxers with a high alkaline (pH) content; available in varying formulations
Hydroxide Relaxers
also known as 'No-Lye Relaxers,' do not require a base cream to be applied to the skin or scalp
No-Base Relaxer
Also known as 'End Bonds,' connect amino acids (end to end) that form polypeptides
Peptide bonds
Consists of 2 or more types of matter;
Physical Mixture
Sodium Hydroxide relaxers of _____ alkaline content
High
Sodium Hydroxide (Lye)
Known as 'thio relaxers' by industry standards, are chemical compounds with the additive ingredient ammonia; considered to be a 'no-lye' relaxer, suitable for soft curl reformation
Thioglycolate Relaxers
The layer of hair that contains melanin
Cortex
Outermost layer of the hair;
Cuticle
The process of removing one sulfur atom and replacing it with a disulfide bond
Lanthionization
a very strong alkaline ingredient used in chemical relaxers; typically marketed as no-mix, no lye
Potassium Hydroxide/ Lithium Hydroxide
A combination of ammonia and thioglycolic acid that creates a reducing agent used in permanent waves and relaxers
Ammonium Thioglycolate (AGT)
Chemically altering naturally curly or wavy hair into straight
Chemical Relaxer
The ability of hair to absorb any liquid
Porosity
A texture service that restructures overly curly hair into loose curls or waves
Soft Curl Deformation
A relaxer requiring the mixing of 2 products; advertised as 'no-lye' for sensitive skin
Guanadine Hydroxide
a mild, alternative relaxing containing a low pH compatible with thio relaxers
Ammonium Bisulfite Relaxer
The study of hair, its care, disorders and diseases of the hair
Trichology
The capability of the hair strand to stretch and return to its previous form without breaking;
Elasticity
when a substance is not able to mix with another substance
Immiscible
Requires a protective base cream to be applied to the hairline and scalp; when a relaxer is labeled 'base relaxer,' it means the relaxer is too strong to be applied without the application of a base cream.
Base Relaxer
Chemically restoring disulfide bonds to harden into a new shape;
Neutralizing
Measurement of how thin or thick a liquid is;
Viscosity
Disulfide bonds connect 2 sulfer atoms located in the amino acid is called;
Cysteine
Any illness caused by overexposure to certain ingredients and or products
Occupational Disease
