Which practice most effectively reduces frizz when styling straight hair?

• A. Let hair air dry with no product.
• B. Use a rough towel dry and apply oil only.
• C. Use a smoothing iron at any temperature with no protection.
• D. Smooth with tension, apply heat protectant, use a smoothing device at appropriate temperature, and finish with a shine product.

Answer: (D)

Frizz is best controlled by smoothing the hair while protecting and sealing the cuticle. The combination of smoothing with gentle tension, a heat protectant, and a smoothing device set to an appropriate temperature targets three key needs: it minimizes friction so the cuticle lies flat, shields strands from heat damage that can lift the cuticle, and then seals the surface for a sleek finish. Finishing with a shine product helps lock in that smooth surface and adds a protective, humidity-resistant layer. Air drying with no product leaves moisture to swell the cuticle and ends up creating frizz. Rough towel drying introduces physical friction that roughs up the cuticle. Oil alone without heat protection doesn’t guard against heat damage and can weigh hair down. A smoothing iron used at any temperature without protection can damage the cuticle, often making frizz worse once the hair cools.
