Hair Removal Techniques (Waxing, Tweezing, Depilatories)
Hair growth and waxing
Hair has anagen (growth), catagen (transition), and telogen (resting) phases. Waxing works best in anagen. Soft wax is applied thin in the direction of hair growth and removed against the growth with firm support; hard wax is applied thicker, allowed to firm, and removed against the growth. Test temperature on your wrist or a small area.
Contraindications and patch tests
Avoid waxing over isotretinoin, recent retinoid use, recent chemical peel or laser, sunburn, active infection, open skin, varicose veins, moles, and irritated skin. Diabetes, blood thinners, and pregnancy require caution and possibly medical clearance. Patch test depilatories and tint 24–48 hours before. Depilatories use thioglycolate to break disulfide bonds; follow the timer exactly and never leave product on irritated skin.
Tweezing and aftercare
Tweeze in the direction of growth, one hair at a time, with clean tools. After waxing, soothe, avoid heat, friction, and tight clothing for 24 hours, and recommend SPF. Ingrown hairs are reduced with gentle exfoliation and avoiding tight clothing.
Traps
Questions reverse the direction rule, skip patch tests, or allow waxing over a recent peel. “Hard wax is always better” is false; selection depends on area and hair. Do not wax over a mole or broken skin.
Worked rule
If a client used a retinoid two days ago, reschedule; if they use it nightly, stop waxing and refer for a plan.
