Hair removal chapter 11

anagen

first stage of hair growth during which new hair is produced

axilla

the correct professional and anatomical term for the underarm; the region between the arm and the thoracic wall

blend ( for electrolysis )

modality of electrolysis combining alternating current (AC) and direct current (DC )

candelilla

hard wax used to modify the melting point and provide increased strength to hard depilatory wax

carnauba

hard wax used to modify the melting point and provide increased strength to hard depilatory wax

catagen

second transition stage of hair growth; in this phase, the hair shaft grows upward and detaches itself from the bulb

depilation

process of removing hair at the skin level

depilatory

substance, usually a caustic alkali preparation , used for temporarily removing superfluous hair by dissolving it at the skin level

electrolysis

removal of hair by means of an electric current that destroys the hair root

epilation

removes hair from the follicles; waxing or tweezing

galvanic electrolysis

direct current utilized in electrolysis

glabella

the area between the eyebrows at the top of the nose

gum rosin

an addictive in soft wax

hair bulb

swelling at the base of the follicles that provides the hair with nourishment; it is a thick, club shaped structure that forms the lower part of the hair root

hair follicle

mass of epidermal cells forming a small tube or canal; the tube like depression or pocket in the skin or scalp that contains the hair root

hair papilla

cone shaped elevations at the base of the follicle that fit into the hair bulb; the papillae are filled with tissue that contains the blood vessels and cells necessary for hair growth and follicle nourishment

hair root

anchors hair to the skin cells and is part of the hair located at the bottom of the follicle below the surface of the skin; part of the hair that lies within the follicle at its base, where the hair grows

hair shaft

portion of the hair that extends or projects beyond the skin, consisting of the outer layer ( cuticle ), inner layer ( medulla ), and middle layer ( cortex ); color changes happen in the cortex

lanugo

hair on a fetus; soft and downy hair

laser hair removal

photo epilation hair reduction treatment in which a laser beam is pulsed on the skin using one wavelength at a time, impairing hair growth, an intense pulse of electromagnetic radiation

rosin

resin used in the manufacture of soft wax

sugaring

ancient method of hair removal; original recipe is a mixture of sugar, lemon juice and water that is heated to form a syrup, molded into a ball, and pressed onto the skin and then quickly stripped away

syndrome

group of symptoms that, when combined, characterize a disease or disorder

telogen

also known as resting phase, the final phase in the hair cycle that lasts until the fully grown hair is shed

terminal hair

longer coarse hair that is found on the head, face and body

threading

also known as banding; method of hair removal; cotton threading is twisted and roll along the surface of the skin, entwining hair in the thread and lifting it out of the follicle

trichology

scientific study of hair and its disease and care

thermolysis

uses alternating current (AC) that is applied and emitted from the probe, inserted into the follicle of the hair to be eliminated, to destroy the dermal papillae

vellus hair

also known as lanugo hair, short and fine, unpigmented downy hair that appears on the body, except for the palms of the hands and the soles of the feet

vermillion border

border of the lip line

hypertrichosis

excessive hair growth of terminal hair in areas of the body that normally grow only vellus hair ( lower back, eyelids, abdomen ). genetically inherited and not stimulated by male androgens

hirsutism

excessive hair growth on the face, chest, underarms, and groin, especially in women. caused by excessive male androgens in the blood.
