Relaxers that require the application of protective base cream to the entire scalp prior to the application of the relaxer.

Hair services that cause a chemical change that altars the natural wave pattern of the hair.

Use the same ammonium thioglycolate that is used in permanent waving, but at a higher concentration and a higher pH (above 10).

Oily cream used to protect the skin and scalp during hair relaxing.

Create an exothermic chemical reaction that heats up the waving lotion and speeds up processing.

A process or service that rearranges the structure of curly hair into a straighter or smoother form.

Perms that use an ingredient that does not evaporate as readily as ammonia, so there is very little odor associated with their use.

Compounds made up of carbon, oxygen, hydrogen, nitrogen, and sulfur.

Perm in which the hair strands are wrapped from the ends to the scalp in overlapping concentric layers.

Perm rods that have a smaller diameter in the center that increases to a larger diameter on the ends.

Perm wrap in which partings and bases radiate throughout the panels to follow the curvature of the head.

Active ingredient or reducing agent in alkaline permanents.

Perm wrap in which one end paper is folded in half over the hair ends like an envelope.

Base control in which the hair is wrapped at an angle of 90 degrees or perpendicular to its base section, and the rod is positioned half off its base section.

Weak physical side bonds that are also the result of an attraction between opposite electrical charges; they are easily broken by water (wet setting) or heat (thermal styling), and they re-form as the hair dries or cools.

Perm wrap that is similar to double flat wrap but uses only one end paper, placed over the top of the strand of hair being wrapped.

Perm wrap in which one end paper is placed under and another is placed over the strand of hair being wrapped.

Position of the tool in relation to its base section, determined by the angle at which the hair is wrapped.
