What is defined as follows:

Scabies “itch” is a highly contagious skin disease caused by the itch mite burrowing under the skin. Vesicles (blisters) and pustules (inflamed pimples with pus) usually form on the scalp from the irritation caused by this animal parasite. Excessive itching results in scratching the infected areas and makes the condition worse. Practicing approved sanitization and disinfection procedures will help prevent the spread of this disease. A client with this condition should be referred to a physician for medical treatment.
tint removers
Related Term: color prepared commercial products designed to remove artificial pigment from the hair
Related Term: pomade styling product that adds considerable weight to the hair by causing strands to join together, showing separation in the hair
Telogen effluvium has what percentage of hairs in telogen?
Pediculosis capitis
Pediculosis capitis is the infestation of the hair and scalp with head lice. Pediculosis capitis (puh-dik-yuh-LOH-sis KAP-ih-tis) is the infestation of the hair and scalp with head lice. As these animal parasites feed on the scalp, itching occurs and the scratching that usually results can cause an infection. Head lice are transmitted from one person to another by contact with infested hats, combs, brushes, and other personal articles. You can distinguish them from dandruff flakes by looking closely at the scalp with a magnifying glass.
Acquired canities
Acquired canities develops with age and is the result of genetics. Although genetics is also responsible for premature canities, acquired canities may develop due to worry, anxiety, or prolonged illness.

barrel curls
pin curls with large center openings; are fastened to the head in a standing position on a rectangular base
Hydrogen bonds
Hydrogen bonds are very weak side bonds, but there are so many of them that they account for about one-third of the hair's strength. A hydrogen bond is a physical side bond that is easily broken by water or heat. Although individual hydrogen bonds are very weak, there are so many of them that they account for about one-third of the hair's overall strength.
Coarse hair has the largest diameter and is stronger than fine hair. It is stronger than fine hair, for the same reason that a thick rope is stronger than a thin rope. Coarse hair also has a stronger structure. It usually requires more processing than medium or fine hair and may also be more resistant to that processing. It is usually more difficult for hair lighteners, haircolors, permanent waving solutions, and chemical hair relaxers to penetrate coarse hair.
The first stage of hair growth, anagen, is the growth stage. During the anagen (AN-uh-jen) or growth phase,which lasts from three to five years, new hair is produced. The hair actively manufactures new keratinized cells in the hair follicle. During this phase, hair cells are produced faster than any other normal cell in the human body.

Complete body hair loss is called alopecia universalis
pityriasis capities simplex

wave pattern
amount of movement in the hair strand; described as straight, wavy, curly, and extremely curly
A cowlick is a tuft of hair standing straight up.
The cortex is the middle layer of the hair. It is a fibrous protein core formed by elongated cells containing melanin pigment. About 90 percent of the total weight of hair comes from the cortex. The elasticity of the hair and its natural color are the result of the unique protein structures located within the cortex. The changes involved in oxidation haircoloring, wet setting, thermal styling, permanent waving, and chemical hair relaxing all take place within the cortex.
A whorl is hair that forms a circular pattern.
Extremely curly hair
Extremely curly hair tends to be highly oval and even flat.
The cortex, middle layer of the hair, is made up of millions of polypeptide chains. These polypeptide chains are cross-linked together, like a ladder, by three different types of side bonds: hydrogen bonds, salt bonds, and disulfide bonds. These side bonds hold the hair fibers in place and account for the incredible strength and elasticity of human hair. These side bonds are essential to wet sets, thermal styling, permanent waving, and chemical hair relaxing

The ratio of eumelanin to pheomelanin

Form is the outline of the overall hairstyle as seen from all angles. It is three-dimensional and changes as it is viewed from different angles. The silhouette is typically the aspect of the overall design that a client will react to first. Generally, it is best to use forms that are simple and pleasing to the eye. The hair form should be in proportion to the shape of the head and face, the length and width of the neck, and the shoulder line.
