Placing the client under a heated dryer may be necessary for which treatment?

• A. To dry the hair quickly after a haircut
• B. To test the humidity level
• C. For a deep conditioning treatment
• D. To set a temporary hair color

Answer: (C)

Placing a client under a heated dryer is most effective for a deep conditioning treatment because the heat opens the hair cuticle and helps the conditioning agents penetrate and lock in moisture. This warmth accelerates the conditioner’s absorption, which improves softness, elasticity, and manageability compared with applying conditioner without heat. While a dryer can dry hair after a haircut or be used in other contexts, those tasks don’t rely on heat to activate conditioning ingredients. Humidity testing and color setting involve different steps and tools, so they’re not the best match for this purpose.
