6.3.1. Tweezing, Threading, and Depilatory Creams

💡 First Principle: Tweezing, threading, and depilatories are manual or chemical methods that remove hair at or near the surface without requiring heat. They have a narrower application range than waxing and are most appropriate for small, targeted areas.

Tweezing:

• Removes individual hairs by gripping the hair shaft close to the skin and pulling in the direction of growth
• Best for: Eyebrow shaping, stray hairs
• Infection control: Tweezers are multi-use metal tools — must be cleaned and disinfected between clients
• Never tweeze inside the nose or inside the ear canal
• Precision tool — slower than waxing but allows exact shaping control

Threading:

• Uses a twisted cotton thread to trap and pull multiple hairs simultaneously
• Popular for eyebrow shaping, upper lip, and facial hair
• No products applied to skin — suitable for clients who cannot use waxing products
• Requires specialized skill; relatively low risk of skin trauma when done correctly
• Not appropriate over active acne or irritated skin

Depilatory creams:

• Chemical hair removal using alkaline chemicals (thioglycolate compounds) that break down the disulfide bonds in keratin, dissolving the hair shaft at the skin surface
• Results last slightly longer than shaving (hair removed at/just below surface vs. above)
• Not permanent — does not affect the follicle
• Requires patch test due to significant allergic reaction risk
• Contraindicated on broken skin, irritated skin, near eyes, or any area with sensitivity
• Contact time must be followed exactly — leaving on too long causes chemical burns

⚠️ Exam Trap: Depilatory creams remove hair at the skin surface level — they do not affect the follicle. Results are temporary, similar to shaving. The exam may ask about the mechanism to distinguish depilatories from electrolysis or laser.

Reflection Question: A client asks for threading instead of waxing because she's nervous about the heat. What other factors should you assess before confirming threading as the right choice?
