Test Flashcards
The cortex layer of the hair structure is responsible for the hairs length and texture.
True or False
False
Salt bonds can be broken by water where as disulfide bonds are broken by changes in pH.
True or False
False
In Permanent waving the size of the rod determines the size of the curl.
True or False
True
The single flat wrap uses one end paper folded in half over the hair ends like an envelope.
True or False
False
The process of chemically altering the natural wave pattern of hair is:
Chemical Texture Service
The range of numbers used in the pH scale is:
0-14
Chemical hair texturizers temporarily raise the pH of the hair in order to
Soften and swell
In the restructuring process, coarse, resistant hair with a strong compact cuticle requires a chemical solution that is:
Highly Alkaline
Chemical side bonds formed when two sulfur-type chains are joined together are:
Disulfide Bonds
Hydrogen bonds are easily broken by water or heat and are re-formed when the hair is:
Dry
In permanent waving, the shape and type of curl are determined by the shape and type of rod and the:
Wrapping Method
Rods that are equal in diameter along their entire length or curling area are:
Straight rods
The wrapping technique that provides the most control over hair ends is the:
Dbl flat Wrap
All perm wraps begin by sectioning the hair into:
Panels
In permanent waving, panels of hair are divided into smaller subsections called:
Base Sections
Caution should be used with on-base rod placement to avoid additional:
Stress and Tension
The angle at which a permanent wave rod is positioned on the head is referred to as:
Base Direction
The two methods of wrapping the hair around a perm rod are:
Croquignole and Spiral
In the croquignole method of wrapping, the hair is wound from:
Ends to scalp
Once in the cortex, the waving solution breaks the disulfide bonds through a chemical reaction called:
Reduction
In permanent waving, the reduction reaction is due to the addition of:
Hydrogen
The most common reducing agents used are:
This
