Waxing and Hair Removal Techniques
What this domain tests
Waxing questions test hair biology, wax chemistry, temperature control, patch testing, contraindications, direction of removal, aftercare and infection control.
Core rules and concepts
- Hair cycle: anagen (growth), catagen (transition), telogen (rest). Waxing disrupts anagen hair best; regrowth timing varies.
- Strip wax is applied thinly in the direction of hair growth and removed against it; hot wax is applied thicker, sets around hair and is removed without strips, often for sensitive areas.
- Test wax temperature on the inner wrist; never double-dip spatulas.
- Patch test 24–48 hours before first treatment, especially with tinting or sensitive skin; follow product instructions.
- Contraindications: active infection, open wounds, recent isotretinoin, retinoids on the area, recent chemical peel or laser, sunburn, fragile skin, uncontrolled diabetes and allergy to rosin.
- Aftercare: avoid heat, friction, tight clothing, chlorinated pools and sun for 24–48 hours; advise exfoliation after 48 hours and SPF.
Worked example
A client using topical tretinoin on the upper lip asks for waxing. Reasoning: retinoids thin the stratum corneum and increase skin stripping risk. Refuse waxing on that area, document advice, and suggest trimming or consultation with their prescriber; resume waxing only after the advised washout period.
Traps that cost marks
- Double-dipping.
- Waxing over a changing mole.
- Using strip-wax technique on hot wax.
- Ignoring recent isotretinoin.
- Failing to give aftercare or record patch test results.
