Hair removal techniques (waxing, threading, and related methods)
What this domain tests
Hair removal techniques tests waxing, threading and related methods, including hair growth, skin assessment, hygiene, technique and aftercare.
Core rules
- Hair grows in cycles. Anagen hairs are actively growing and best removed by waxing; telogen hairs are resting. Repeated waxing can reduce density over time but does not stop growth permanently.
- Assess skin and hair, check medications and allergies, and patch test tinted or chemical products. Avoid waxing over active infection, open lesions, sunburn, recent peels or lasers, varicose veins and moles without medical advice.
- Warm wax is applied in the direction of hair growth and removed against it, supporting the skin. Hot wax is applied against growth and removed in the direction; it is useful for coarse hair and sensitive areas.
- Threading uses twisted cotton to trap hairs; it suits facial hair but requires good tension and hygiene.
- Use disposable spatulas and strips; never double-dip. Clean and disinfect tools; wear gloves where appropriate.
- Advise on aftercare: avoid heat, friction, perfumed products and sun exposure briefly; exfoliate later to reduce ingrown hairs; report persistent redness or infection.
Worked example
A client on isotretinoin asks for a lip wax. Because the drug can make skin fragile and impair healing, waxing is typically contraindicated during treatment and for a period afterwards. Explain, decline, and offer a review when the prescriber confirms skin stability.
Traps
Waxing over a mole; double-dipping; removing warm wax in the wrong direction; and ignoring recent retinoid use.
