 liver spots, are benign lesions that occur on the sun-exposed areas of the body

coloring matter or pigment of the skin

also known as a wart, is an hypertrophy of the papillae and epidermis

oil glands of the skin connected to hair follicles

Half off-base placement results from wrapping the hair at an angle of 90 degrees to its base section (Figure 17-31). At this elevation of the hair, the rod is positioned half off its base section. Half off-base placement results in medium volume and movement.

Base control refers to the position of the perm rod or tool in relation to its base section and is determined by the angle at which the hair is wrapped.

Base direction refers to the directional pattern in which the hair is wrapped.

AKA balyage, is the process of painting a lightener or color directly onto clean, styled hair.

the use of the positive pole ( anode) to introduce an acid-pH product, such as an astringent solution, into the skin.

 infuses alkaline (negative) products into the tissues from the negative toward the positive pole.

temporary haircolor: washes out with one shampoo

semipermanent haircolor: washes out or fades within a few weeks

Demipermanents darken the natural hair color when applied. They are available in gel, cream, or liquid forms. Because they contain aniline derivative, a patch test is required before application.  demipermanent: lasts longer than a semipermanent, but not as long as a permanent haircolor

These perms have a pH range between 4.5 and 7.0 and use glyceryl monothioglycolate (GMTG)

Modern acid waves are acid-balanced waves that have a 7.0 or neutral pH. Acid-balanced waves process at room temperature and do not require the heat of a hair dryer for processing. Although GMTG is the primary reducing agent in acid-balanced waves, these waving products usually contain some ATG.

The main active ingredient or reducing agent in alkaline perms is ammonium thioglycolate (ATG)

Egyptian henna, and other plants were used to color the hair.  Henna is still used as a professional haircoloring product, but should be used with caution.

Are permanent haircoloring products

require the use of an outside heat source to activate chemical reactions and processing

all exothermic waves (ek-soh-THUR-mik WAYVZ) have three components:• permanent waving solution• activator• neutralizerThe activator in an exothermic wave, however, contains an oxidizing agent (usually hydrogen peroxide) that causes a rapid release of heat when mixed with the waving solution.

Elevation, also known as projection (pruh-JEK-shun), is the result of lifting the hair section above 0 elevation, or natural fall. This projection of the hair while cutting produces graduation or layers and is usually described in terms of degrees
