Processing & Wave Formation
The wave has reached its peak when it forms this letter.
What is "S"?
Also known as a soft-curl,Jheri curl, or simply a curl; process is used to restructure very curly hair into a larger curl pattern.
What 4 things should you look for when examining the scalp?
What is cuts, abrasions/scratches, open sores, scalp disease?
The hair is composed of these three layers.
What is Cuticle, Cortex, and Medulla? (CCM)
These are the most commonly used perm rod.
What are Concave rods?
Frizziness indicates that the processing time has reached its absolute maximum; beyond this point the hair becomes this.
What is Overprocessed?
Process that chemically rearranges the basic structure of overly curly hair into straighter hair form.
What is Chemical Hair Relaxing?
Name the 6 hair analysis to determine a texture service.
What is porosity, texture, elasticity, density, length, direction of growth?
What layer of the hair is rearranged and restructured during chemical texturizing services?
What is the Cortex?
These are known as base control; what degrees are they rolled and what effect do they give?
What is On-base (full volume, 90 degrees), half-off-base (medium volume, 90 degrees), and off-base (little volume, 45 degrees)
Name at least 3 signs that the hair has been over processed.
What is weak curl formation, curly appearance when wet but completely frizzy when dry, elasticity of the hair is damaged and unable to contract back into the wave formation, feels harsh after dried
Is a combination of a thio-based chemical relaxer and a permanent wave.
What is a curl reformation?
If you notice signs of abrasions or scalp disease present what must you do?
What is do not proceed with service and refer the client to a physician?
Chemical texture sevices involve two principle actions of the hair, what are they?
What is physical and chemical?
What are the two most common types of relaxers?
What are thio and hydroxide relaxers?
Helps determine how the client's hair will react to the permanent wave process.
What is Test Curl?
Process used to chemically restructure natural hair into a different wave pattern.
What's permanent or chemical waving
Hair porosity is classified as?
What is resistant, normal, porous?
Most thio relaxers have a pH of?
What is above 10?
This is the main active ingredient/reducing agent in alkaline perms.
What is ATG (ammonium thioglycolate)?
Name at least 3 aspects a test curl can enable the barber observe.
What is wave formation, degree of wave formation, time when peak of wave formation is reached, identify resistant areas, appropriate product selection?
Name at least 8 things a permanent wave requires.
What is permanent wave rods, end papers, perm solution, neutralizer, cotton coils, gloves, towels, roller clips, clarifying shampoo, plastic tail comb, hair pick, barrier cream, spray bottle, hair clips, timer, chemical cape
This type of hair requires a more alkaline solution to raise the cuticle and permit uniform saturation for processing.
What is resistant hair?
These are strong alkalis that can swell the hair up to twice its normal diameter.
What are Hydroxide relaxers?
This is used as the primary reducing agent in true acid waves.
What is glycerol monothiglycolte (GMTG)?
