Cosmetology and Beauty Therapy

Both waxing and tweezing pull the hair from the root, which can stimulate the follicle to produce thicker, darker hair over time. Shaving only cuts the hair at the surface.

When an ingrown hair is removed, the epidermis often heals over the follicle opening, which can trap the hair again or lead to further inflammation.

A fissure is a crack in the skin that can penetrate the dermis, often caused by extreme dryness or cold, such as chapped lips or hands.

Mild redness and swelling (erythema and edema) are normal, temporary responses to the heat or chemical destruction of the hair follicle during electrolysis.

Thermolysis is considered a monoterminal modality because it uses a single electrode to deliver high-frequency current to the follicle.

Hair follicle shape determines the texture of the hair shaft. A round follicle produces straight hair, while oval or flatter follicles result in wavy or curly hair.

An ulcer is an open sore on the skin or mucous membrane. Keloids and cicatrix are types of scar tissue, and urticaria refers to hives.

An ingrown hair is typically a minor mechanical issue. Freeing the hair allows it to grow normally and the skin to heal without further intervention.

During menopause, hormonal shifts often lead to terminal hair growth in androgen-sensitive areas, most commonly the chin and upper lip.

Scleroderma is a chronic disease characterized by the hardening and thickening of the skin and connective tissues.

Terminal hair growth in women is primarily driven by androgens. An excess of these hormones can lead to hirsutism.

A scale is an accumulation of epidermal flakes, often seen in conditions like psoriasis or dry skin.

Insulated probes are designed to protect the surface of the skin from thermal damage by concentrating the heat at the tip of the probe, thus reducing trauma to the epidermis.

A naevus (or nevus) is the technical term for a birthmark or a mole, which is a localized malformation of skin tissue.

The three standard modalities used in electrolysis are galvanic (direct current), thermolysis (alternating current), and the blend (a combination of both).
