Services
Services
Hair services that cause a chemical change within the hair’s natural wave and curl pattern
Chemical Texture Services
Long chains of amino acids joined together by peptide bonds
Polypeptide Chains
The most common type of perm rod
Concave Rods
Is a process that rearranges the structure of curly hair into a straighter or smoother form
Chemical Hair Relaxing
Natural pH of hair
4.5 to 5.5
Loosening overly curly hair; changing tightly curly or coiled hair into loose curls or waves
Curl Re-forming
Also known as end bonds, are chemical bonds that join amino acids together, end-to-end in long chains, to form a polypeptide chain.
Peptide Bonds
Equal in diameter along their entire length or curling area.
Straight Rods
Use the same ATG that is used in permanent waving but at a higher concentration and a higher pH
Thio Relaxers
When does most of the processing take place in permanent waving?
Within the first 5 - 10 minutes
Adding wave or curl to the hair
Permanent waving
Long, coiled polypeptide chains
Keratin proteins
Usually about 12 inches long with a uniform diameter along the entire length of the rod
Soft Bender Rods
The measurement of the thickness or thinness of a liquid that affects how the fluid flows.
Viscosity
What is the pH range of the acid waves found in today's salons?
7.8 and 8.2
Removing curl or waves; leaving the hair smooth and straight
Relaxing
Compounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur
Amino Acids
Also known as circle rod, is usually about 12 inches long with a uniform diameter along the entire length of the rod
Loop Rods
What is the active ingredient in all hydroxide relaxers?
Hydroxide ion
Keratin straightening treatments eliminate up to ______ % of frizz and curl?
95%
List 1 of the 5 reasons why you should study chemical texture services
1. Allow stylists the opportunity to offer clients options to change the texture of their hair

5. Without understanding, cosmetologists could damage hair, cause hair loss, and harm their clients and themselves.
What are the 3 types of side bonds? Which one is the strongest, easily broken by change in ph and easily broken by water/heat?
1. Disulfide—the strongest of the three side bonds
2. Salt—easily broken by changes in pH
3. Hydrogen—are easily broken by water or heat
What are the 3 types of end papers? Describe each one
1. Double Flat Wrap—one end paper is placed under and another is placed over
2. Single Flat Wrap—uses only one end paper, placed over the top
3. Bookend Wrap—one end paper folded in half like an envelope
What are the 4 types of hydroxide relaxers?
1. sodium hydroxide
2. potassium hydroxide
3. lithium hydroxide
4. guanidine hydroxide
A properly processed permanent wave should break and rebuild approximately _____% of the hair’s disulfide bonds
50%
