Glossary of terms in detail

Epicranius

The Epicranius is the muscle of the scalp. The frontal portion, at the forehead, is responsible for raising the eyebrows and wrinkling the forehead. The occipital portion, at the base of the skull, draws the scalp backwards.

Epidermis

The protective outer layer of skin.

Erythema

Is a flushing of the skin due to dilation of the capillaries in the dermis. May be physiological or a sign of inflammation or infection.

Extensions

Hair extensions are bunches of strands or strips of hair, chemically treated human hair or synthetic, which are thermally bonded onto strands (or meshes) of the clients' own hair. Hair extensions add density or colour to natural hair.

Folliculitis

Inflammation of the hair follicles in the skin. Most commonly caused by infection.

Fragilitis Crinium

Is an abnormal fragility or brittleness of the distal tips of the hair shafts.

Frechet

A frechet device is a silicone strip with titanium hooks at either end. It has the ability to stretch to 200% of its original size. It comes in 4 sizes (3,4,5,6), according to the width of area to be removed. It should be removed within 30-40 days. The objective of the frechet is to stretch the hair-bearing scalp without causing any deformation of the head. As the hair-bearing scalp stretches, the bald area is loosened and can then be excised and sutured up. The process is a gradual one and the number of procedures required, depends upon the size of the area of bald scalp.

Galea Aponeurotica

The Galea Aponeurotica is a flat sheet of fibrous tissue that caps the skull and links the two parts of the Epicranius muscle.

Highlighting

Highlighting is the term given to the process of lightening individual strands of hair as opposed to a full head colour. The colour can be applied using either a highlighting cap, through which strands of hair are pulled and coloured; a highlighting gun, which passes colour down individual strands of hair; foils or strips in which individual strands of hair are coloured and then wrapped to separate.

Inflammation

The body's response to injury, which may be acute or chronic. It involves heat, pain, redness, swelling and loss of function of the affected area.
