🗑
|
||||
| The three main layers of the hair shaft are the cuticle, medulla, and | cortex
🗑
|
||||
| Swelling the hair raises the cuticle layer and allows for | penetration
🗑
|
||||
| For chemicals to penetrate a healthy cuticle hair layer, they must | have an alkaline pH
🗑
|
||||
| The fibrous protein core of the hair, formed by elongated cells containing melanin pigment, is the | cortex layer
🗑

🗑
|
||||
| The five main elements that make up the chemical composition of human hair are carbon, oxygen, hydrogen, and | nitrogen and sulfur
🗑
|
||||
| The chemical bonds that hold together the amino acid molecules | peptide bonds
🗑
|
||||
| An end bond is also known as a | peptide bond
🗑
|
||||
| When peptide bonds hold together a very long chain of amino acids, it is called a | polypeptide chain
🗑
|
||||
| The three tupes of cross-links that form the bonds between the polypeptide chains are hydrogen bonds, salt bonds and | disulfide bonds
🗑
|
||||
| A week type of physical side bond that is easily broken by water or heat is a | hydrogen bond
🗑
|
||||
| A salt bond is easily broken by use of | strong aklaline or acidic solutions
🗑
|
||||
| Bonds that must be chemically separated are | disulfide bonds
🗑
|
||||
| Hydrogen chemical hair relaxers break disulfide bonds and during rinsing convert them to | lanthionine bonds
🗑
|
||||
| The natural hair pigment found in the cortex layer of the hair is | melanin
🗑
|
||||
| Two different types of melanin are eumelanin and | pheomelanin
🗑
|
||||
| Natural wave patterns are the result of | genetics
🗑
|
||||
| Asians tend to have | extremely straight hair
🗑
|
||||
| extremely curly hair grows | in long twisted spirals
🗑
|
||||
| to help minimize tangles in extremely curly hair when washing you should use | a detanglinig rinse
🗑
|
||||
| Extremely curly hair may often break or knot easily due to | low elasticity
🗑
|
||||
| Four important factors to consider in hair analysis are texture and porosity | elasticity and density
🗑
|
||||
| The thickness or diameter of the individual hair strand is the | hair texture
🗑
|
||||
| Hair texture is classified as | coarse, medium, or fine
🗑
|
||||
| The measurement of individual hair strands on one square inch of the scalp is | hair density
🗑
|
||||
| The ability of the hair to absorb water or oil is | porosity
🗑
|
||||
| Chemical services performed on hair with low porosity require | more alkaline solutions
🗑
|
||||
| Hair with high porosity is often the result of | over-processing
🗑
|
||||
| The ability of the hair to stretch and return without breaking is | elasticity
🗑
|
||||
| Wet hair with normal elasticity will stretch up to | 50 percent
🗑
|
||||
| When shaping and styling hair, consider the hair's | natural growth pattern
🗑
|
||||
| Dry hair and scalp can be caused by | inactive sebaceous glands
🗑
|
||||
| Oily scalp and hair can be treated by properly shampooing with | normalizing shampoo
🗑
|
||||
| Hair that is not pigmented and almost never has a medulla is | vellus
🗑
|
||||
| Long, soft hair found on the scalp, legs, arms, and bodies of males and females is | terminal
🗑
