How can stylists prevent chemical burns during a perm?

Applying protective barriers like petroleum jelly around the hairline is essential for preventing chemical burns during a perm. This practice creates a physical barrier between the potent chemicals in the perm solution and the sensitive skin on the scalp and hairline. The chemicals used in perm formulations can be harsh and may cause irritation or burns if they come into direct contact with the skin. By generously applying a protective substance, the stylist minimizes the risk of skin reactions, allowing the perm process to proceed safely.

Encouraging the use of protective barriers is standard protocol in chemical hair treatments. This not only enhances the client's comfort but also demonstrates the stylist's professionalism and care. While the other options may contribute to different safety measures or outcomes, using a protective barrier is the most direct and effective method for safeguarding the skin from the harsh chemicals used in perms.
