Hair Removal (Excluding Electrolysis)
Core Concepts
Hair removal methods include waxing (soft and hard), sugaring, threading, tweezing, shaving, depilatories, and laser or light devices where permitted. Know the hair growth cycle: anagen (active growth), catagen (transition), and telogen (resting). Waxing is most effective when hair is in anagen and about ¼ inch long; shorter hair may not be gripped. Distinguish vellus hair (fine, unpigmented) from terminal hair (coarse, pigmented). Hair grows at an angle, so apply wax in the direction of growth, hold skin taut, and remove against the growth with a firm, parallel pull.
Contraindications include isotretinoin within the past 6–12 months depending on protocol, prescription retinoids, recent chemical peels or laser, sunburn, active infection, open lesions, varicose veins, and moles or raised lesions-wax around them, never over. Clients with diabetes, circulatory issues, or compromised immunity need caution and possible medical clearance. Patch-test depilatories 24 hours before use and follow manufacturer timing.
Sanitation is central: never double-dip a wax stick or spatula, use disposable applicators, wear gloves, and disinfect tools and the work area. Post-care includes soothing lotion, avoiding heat, friction, and sun for 24 hours, and advising about ingrown hairs. Threading uses twisted cotton thread to trap hair; sugaring uses a water-soluble sugar paste.
Traps
A common trap is waxing over a mole or double-dipping. Another is assuming all hair removal is safe during pregnancy or with retinoid use; check contraindications and refer when unsure.
Worked Example
For an upper-lip wax, cleanse, powder, test temperature on your wrist, apply a thin strip in the direction of growth, hold skin taut, and remove against growth. Never reapply wax to the same area in one session.
