base placement - ANSRefers to the position of the rod in relation to its base section; base is
determined by the angle at which the hair is wrapped.
on base placement - ANSBase control in which the hair is wrapped at a 45-degree angle
beyond perpendicular to its base section, and the rod is positioned on its base. (greater volume)
half of base placement - ANShair is wrapped at a 90° perpendicular to its base section rod is
positioned half off its base section minimize stress and tension on hair
off-base placement - ANSBase control in which the hair is wrapped at 45 degrees below the
center of the base section, so the rod is positioned completely off its base. (least volume)
Base direction - ANSAngle at which the rod is positioned on the head (horizontally, vertically, or
diagonally); also, the directional pattern in which the hair is wrapped.
base sections - ANSSubsections of panels into which hair is divided for perm wrapping; one rod
is normally placed on each base section.
Base - ANSfoundation of curl . area closest to the scalp panel of hair which roller is placed
stem - ANSbetween the base and first arch (turn) gives curl definition and mobility hair between
scalp and the first turn of the roller
circle - ANSforms a complete circle the wave size of a curl will determine width/wave and
strength
No stem curl - ANS(Betty boo) on base of curly , tight firm long lasting minimum mobility
Half stem curl - ANSCurl placed half off the base; permits medium movement and gives good
control to the hair.
full stem movement - ANSgreatest mobility placed completely of base near scalp will be flat and
almost straight give hair strong define direction
Exothermic - ANSproduces heat (alkaline) heats up waving solution
Endothermic - ANSAbsorbs/require heat (acid) use hooded dryer (less damaging)
ammonia-free waves - ANSPerms that use an ingredient that does not evaporate as readily as
ammonia, so there is very little odor associated with their use.
, thio-free waves - ANSPerm that uses an ingredient other than ATG as the primary reducing
agent, such as cysteamine or mercaptamine. (Still damaging )
low-pH waves - ANSPerms that use sulfates, sulfites, and bisulfites as an alternative to
ammonium thioglycolate (atg) they have a low pH. Weak don't provide strong curl
hair density - ANSThe number of individual hair strands on 1 square inch of scalp.
hair porosity - ANSThe ability of the hair to absorb moisture
Hair elasticity - ANSThe ability of the hair to stretch and return to its original length
Low porosity - ANSWhen the cuticle is tight and the hair is resistant, it is difficult for moisture or
chemicals to penetrate. What term describes this condition?
High porosity - ANSWhen the cuticle is lifted and the hair is overly porous and takes color
quickly the hair would be said to have
Average porosity - ANSThe cuticle is slightly raised. The hair is normal and processes in an
average amount of time. (Normal)
Curl rearranger - ANSreduces peptide bonds so hair can relax and become straight; thio-based
product (Thio based) (atg)
Curl booster - ANSassists hair to assume new shape of rod when wrapping hair in perm rods;
milder form of thio
curl activator - ANSHelps new curl configurations retain their shape and provides moisture;
applied frequently after every shampoo
Instant Moisturizer - ANSHelps replace natural moisture and oils lost during chemical processes
How many steps are in curl reformation - ANS2 steps
How many times do you unwind a curl for a curl test - ANS1/1.2
exterior length - ANSBottom
Interior length - ANSOn top
Volume indentation - ANSBrush is positioned underneath
indentation - ANSBrush is positioned on top of hair strand
