Texture Services
Remove curl or wave leaving hair smooth and straight
What is a relaxer
What bonds are broken by water and heat
Hydrogen Bonds
Relaxers raise what layer of the hair shaft
The cuticle
Potential Hydrogen
What type of shampoo is needed after a relaxer
Neutralizing shampoo
Adds wave or curl to the hair; also used to loosen curls
Permanent waving
How are hydrogen bonds reformed?
Once the cuticle is raised the hair becomes open so that the relaxer can reach the __________.
Cortex
What is the number range for the pH scale
o - 14
What is density
The number of hairs per square inch
Smooths curly and wavy hair textures and eliminates frizz
Keratin based smoothing treatment
How are disulfied bonds broken?
Chemicals
Hydroxide relaxers are acidic. True or False
False
Hydroxide relaxers are alkaline
If a substance has a pH above 7 it is considered acidic
True or False
False
a pH above 7 is alkaline
Is hair with high porosity considered acidic or alkaline

Disulfied bonds can be broken by water
True of False
False
Disulfied bonds are only broken by chemicals
What substance has a neutral pH balance of 7
Rain water
Why should a chemical relaxer never be combined with a permanent color service on the same day?
Because of the bonds that are broken. Relaxers and permanent color both breaks down the disulfide bonds and the disulfide bonds can not be reformed.
