What type of wax may cause an allergic reaction and should be patch tested on the client before use?

• A. Soft wax
• B. Hard wax
• C. Gel wax
• D. Beeswax

Answer: (A)

Patch testing before waxing is essential to identify allergic reactions to wax ingredients. Soft wax is a warm, pliable formula that often contains rosin (a resin) and fragrances to improve grip and scent. Rosin is a common contact allergen, and in susceptible clients it can trigger redness, itching, swelling, or a rash where the wax is applied. Because soft wax often includes these ingredients, it carries a higher risk of triggering an allergic reaction, so testing a small area first helps prevent a full-session reaction. While other wax types can also cause sensitivities, the combination of rosin and additives in soft wax makes patch testing especially important for this option.
