EXAM Questions and Answers
1. base placement
Answer 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.
2. on base placement
Answer 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)
3. half of base placement
Answer 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
4. off-base placement
Answer 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)
5. Base direction
Answer Angle at which the rod is positioned on the head (horizontally, vertically, or diagonally); also,
the directional pattern in which the hair is wrapped.
6. base sections

,Answer Subsections of panels into which hair is divided for perm wrapping; one rod is normally
placed on each base section.
7. Base
Answer foundation of curl. area closest to the scalp panel of hair which roller is placed
8. stem
Answer between the base and first arch (turn) gives curl definition and mobility hair between scalp
and the first turn of the roller
9. circle
Answer forms a complete circle the wave size of a curl will determine width/wave and strength
10. No stem curl
Answer (Betty boo) on base of curly, tight firm long lasting minimum mobility
11. Half stem curl
Answer Curl placed half off the base; permits medium movement and gives good control to the
hair.
12. full stem movement
Answer greatest mobility placed completely of base near scalp will be flat and almost
straight give hair strong define direction

, 13. Exothermic
Answer produces heat (alkaline) heats up waving solution
14. Endothermic
Answer Absorbs/require heat (acid) use hooded dryer (less damaging)
15. ammonia-free waves
Answer Perms that use an ingredient that does not evaporate as readily as ammonia, so there
is very little odor associated with their use.
16. thio-free waves
Answer Perm that uses an ingredient other than ATG as the primary reducing agent, such as
cysteamine or mercaptamine. (Still damaging )
17. low-pH waves
Answer 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
18. hair density
Answer The number of individual hair strands on 1 square inch of scalp.
19. hair porosity
Answer The ability of the hair to absorb moisture
