Hair Removal (Waxing, Sugaring, and Threading)
What the exam tests
Hair removal questions test hair growth cycles, wax and sugar technique, threading, contraindications, and infection control.
Core rules
- Hair grows in anagen (active), catagen (transition), and telogen (resting) phases; waxing is most effective in anagen.
- Soft wax is applied thin and removed with strips; hard wax is applied thicker and removed without strips; sugar is water-soluble and less heat-dependent.
- Threading uses twisted cotton thread to trap and lift hair; it suits short hairs and sensitive areas but still requires clean technique.
- Test wax temperature on your wrist or inner arm; never double-dip applicators.
- Clean and disinfect surfaces; use gloves; dispose of strips and spatulas.
- Contraindications: isotretinoin, recent retinoid or acid use, recent peels, sunburn, active infection, varicose veins, compromised skin, and blood thinners (relative).
- Aftercare: soothe, avoid heat, friction, and sun; advise against picking.
Worked example
A client used tretinoin two days ago and wants a brow wax. Reasoning: retinoids thin the stratum corneum and increase tearing. Reschedule, document, and advise waiting per the prescriber’s guidance-often about a week or more.
Traps
Double-dipping; waxing over a mole or broken skin; ignoring recent exfoliation; and applying wax too hot.
