CHEMISTRY OF PERMANENT WAVING
PERM TOOLS
APPLICATION AND PROCESSING
100
these are subsections of panels
What is base sections
100
another name for a basic wrap
What is straight set
100
polypeptide chains are long chains of amino acids joined together by these bonds
What is peptide bonds
100
straight rods are equal in this measurement
What is diameter
100
The length of time required for the hair to absorb the waving lotion and for the hair to re-curl
What is processing time
200
base control refers to the position of the tool in relation to this
What is base panel
200
this wrap creates movement that curves within sectioned out panels
What is curvature
200
the main active ingredient in acid-balanced waving lotions
What is glycerol monothioglycolate
200
these rods have a small diameter in the center and gradually increase diameter at the ends.
What is concave
200
the chemical action of this product breaks the disulfide bonds and softens the hair
What is waving lotion
300
in this base placement, the hair is wrapped 45 degrees BEYOND perpendicular to it's base section
What is on-base
300
this perm wrap is used to prevent noticeable splits and to blend the flow of hair
What is brick lay
300
These bonds are formed when the sulfur atoms in 2 adjacent polypeptide chains are joined together
What is disulfide
300
End wraps are absorbent papers used to control this part of the hair strand while winding the hair on a perm tool
What is the ends
300
waves that process more quickly and produce firmer curls than TRUE ACID waves
What are acid-balanced
400
in this base placement, the hair is wrapped at 90 degrees perpendicular to it's base section
What is half-off base
400
this wrap is done at an angle that causes the hair to spiral up the rod like the grip on a tennis racket
What is spiral
400
the main active ingredient or reducing agent in an alkaline perm
What is ammonium thioglycolate
400
this wrap you place one end paper on top of the hair and hold it flat
What is single-flat wrap
400
once processed, the hair is rinsed for this length of time prior to neutralization
What is 5 minutes
500
in this base placement, the hair is wrapped at a 45 degree angle BELOW perpendicular to it's base section and creates the least amount of volume
What is off-base
500
this method of wrapping a perm is best for very long hair
What is piggy-back or double tool technique
500
known as a perm activated by an outside heat source
What is endothermic
500
in this wrap, one end wrap is folded in half over the hair like an envelope
What is book-end wrap
500
in neutralization,this is when the disulfide bonds are reformed
What is immediately
