Chemical Basics
This determines the strength of a reducing agent in a chemical texture service
What is the concentration of thio (thioglycolic acid) in the solution
The two main actions of waving lotion are
What is soften and swell the hair; break disulfide bonds
This type of relaxer uses no lye
What is a thio relaxer
This relaxer is used in soft curl permanent services
What is Thio relaxer
This should always be performed before a chemical texture service
what is consultation/analysis of scalp and hair
This type of bond is broken and rearranged durning chemical texture services
What is a disulfide bond
This determines curl size in a permanent wave
What is rod size
Another term for sodium hydroxide relaxer is

Soft curl perms are designed mainly for this hair type
What is Extremely curly hair
Metal tools should be avoided during chemical texture services because
What is they can react with the chemicals
pH measures. . .

What is spiral wrap
The degree of straightening in a relaxer service is
What is relaxation
The primary purpose of a soft curl permanent
What is to loosen overly curly hair into larger, more manageable curls
This is an important test during a relaxer service to check processing

What is Lanthionization
The chemical used for both soft curl permanents and thio relaxers
What is ammonium thioglycolate
This is essential to restore the hair's pH after a chemical texture service
What is proper neutralization
