Which item protects the client's skin from chemicals when applied around the hairline?

• A. Tail comb
• B. End papers
• C. Cotton strips
• D. Plastic cap

Answer: (C)

The concept here is creating a protective barrier to keep chemicals away from the skin during processing. Cotton strips are placed along the hairline to shield the skin from waving lotion and neutralizer, absorbing any drips and preventing irritation or chemical burns. The other items have different roles: a tail comb is for sectioning the hair, end papers protect the hair ends, and a plastic cap helps retain heat during processing—not to protect the skin. So cotton strips are the best choice for safeguarding the skin at the hairline.
