Hair Removal (Waxing, Tweezing, and Related Methods)
What this domain tests
Hair removal questions test wax type and temperature, hair growth cycles, contraindications, and sanitation.
Core rules
- Hair cycles: anagen, growth; catagen, transition; telogen, rest. Waxing is most effective when hair is in anagen and about 1/4 inch long.
- Soft wax is spread thin and removed with a strip; hard wax is applied thicker, sets, and is removed without a strip, making it useful for sensitive areas.
- Test wax temperature on yourself or a strip; never double-dip a stick into the pot. Use disposable spatulas and gloves.
- Contraindications: isotretinoin, recent retinoid use, recent peels or laser, sunburn, open lesions, active infection, varicose veins, moles, and fragile or bruised skin.
- Aftercare: soothe, avoid heat, friction, and sun; advise against tight clothing and exfoliate gently after healing.
Worked example
A client on tretinoin wants a lip wax. Refuse waxing and explain why; offer tweezing only if skin is intact. Reasoning: retinoids reduce epidermal thickness and healing, so wax can avulse skin and leave a wound.
Traps
Waxing over a mole; double-dipping; applying wax with the hair growth and removing with it; ignoring a recent chemical peel; using hot wax on inflamed skin.
