25
cuticle:exterior of the hair
cortex:middle layer of the hair
medulla:innermost layer of the hair, may be missing in fine hair
potential of hydrogen:pH literally means this
polypeptide chains:long chains of amino acids linked together peptide or end bonds
cortex:is made up of millions of polypeptide chains cross linked by the three side bonds
disulfide bonds:strong chemical side bonds formed when the sulfer atoms in two adjacent protein chains are joined together
salt bonds:weak physical side bonds that are the result of an attraction between negative and positive electric charges
salt bonds:are easily broken by changes in pH, and reform when the pH has returned to normal
hydrogen bonds:weak physical side bonds that are also the results of an attraction between opposite electrical charges
hydrogen bonds:easily broken by water or heat, reformed as hair dries or cools
texture:describes the diameter of a single hair strand, classified as coarse, medium or fine
resistant hair:has a tight, compact cuticle layer that resists penetration
concave rods:most common perm rod, smaller center diameter
straight rods:equal diameter along the entire length, uniform curl
base section:each subsection of the quad is sectioned into these
base direction:refers to the angle at which the rod os postioned on the head
reduction:the waving solution breaks the disulfide bonds through a chemical reaction called _________
thiol:the reducing agent used in permanent waving solutions are _____ compounds
thioglycolic acid:colorless liquid with a strong, unpleasant odor, is the most common reducing agent
ammonium thioglycolate:the addition of ammonia to thiogycolic acid produces a chemical called _______ _____________
glyceryl monothioglycolate:also known as GMTG, is an acid with low pH, the primary reducing agent in all acid waves
exothermic waves:create an exothermic chemical reaction that heats up the solution and speeds up the processing
endothermic waves:are activated by an outside heat source like a hood dryer
basic perm wrap:all rods within the panel move in the same direction
curvature perm:rods follow the curve of the head
weave technique:uses zig zag pattern to divide base sections
spiral perm:the hair is wrapped at an angle other than perpendicular to the length of the rod
thio relaxers:break disulfide bonds and soften hair, just as perms
hydroxide relaxers:hydroxide ion is the active ingredient in all _________ ________
no mix no lye:lithium hydroxide and potassium hydroxide relaxers are often advertised and sold as __ ___ __ ___ relaxers
base cream:oily substance used to protect the skin and scalp during hair relaxers
base relaxers:require the application of the protective cream to the entire scalp
cortex:middle layer and gives the hair the majority of it's strength and elasticity
eighty:a healthy cortex contributes about ______ percent to the overall strength of the hair
melanin:the cortex contains the natural pigment called _______ that determines hair color
high porosity:the cuticle is lifted, the hair is overly porous and takes color quickly, also tends to fade faster
eumalanin:give black and brown to hair color
pheomelanin:gives blonds and reds to hair color
contributing pigment:lies under the natural hair color and must be taken into consideration when selecting haircolor
primary colors:pure colors that cannot be achieved from mixing colors
temporary haircolor:the pigment in ________ _________ are large and do not penetrate the cuticle layer
aniline derivatives:contain small, uncolored dyes that combine with hydrogen peroxide to form larger, permanent dye molecules within the cortex
metallic haircolor:contain metal salts and change hair color gradually by progressive build up
hydrogen peroxide:is the most commonly used developer used in haircolor
developer:is an oxidizong agent that when mixed with a oxidation haircolor, supplies the necessary oygen gas to develop the color molecules a create a change in natural hair color
volume:measures the concentration and strength og hydrogen peroxide
nonmetallic:use a ___________ mixing bowl
single process:lightens and deposits color in a single application, virgin and retouch are examples
virgin:haircoloring refers to the first time hair has ever been colored
double proess:by first decolorizing the hair with a lightener and then using a separate product to deposit the desired the tone
prelightened:lifting or lightening the natural pigments before the application of a toner
oil lighteners:the mildest type, one or two levels of lift, also used on facial and body hair
cream lighteners:strong enough for high lift blonding, but gentle enough to be used on the scalp
presoftening:raises the cuticle layer of gray or resistant hair to allow for better penetration of color
two levels:formulate ___ ______ lighter than the natural hair color the ensure a natural result with gray or salt and pepper
soap cap:to brighten haircolor, refresh reds with a ____ ___ of equal parts shampoo and the remaining color formula before rinsing
