Questions And Correct Answers
base placement
Refers 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
Base 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
hair 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
Base 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
,Angle 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
Subsections of panels into which hair is divided for perm wrapping; one rod is normally
placed on each base section.
Base
foundation of curl . area closest to the scalp panel of hair which roller is placed
stem
between the base and first arch (turn) gives curl definition and mobility hair between
scalp and the first turn of the roller
circle
forms a complete circle the wave size of a curl will determine width/wave and strength
No stem curl
(Betty boo) on base of curly , tight firm long lasting minimum mobility
,Half stem curl
Curl placed half off the base; permits medium movement and gives good control to the
hair.
full stem movement
greatest mobility placed completely of base near scalp will be flat and almost straight
give hair strong define direction
Exothermic
produces heat (alkaline) heats up waving solution
Endothermic
Absorbs/require heat (acid) use hooded dryer (less damaging)
ammonia-free waves
Perms 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
, Perm that uses an ingredient other than ATG as the primary reducing agent, such as
cysteamine or mercaptamine. (Still damaging )
low-pH waves
Perms 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
The number of individual hair strands on 1 square inch of scalp.
hair porosity
The ability of the hair to absorb moisture
Hair elasticity
The ability of the hair to stretch and return to its original length
Low porosity
When the cuticle is tight and the hair is resistant, it is difficult for moisture or chemicals
to penetrate. What term describes this condition?
