What is the purpose of barrier cream in perm services?

• A. To hold perm rods
• B. To protect the skin from chemicals
• C. To accelerate processing
• D. To lighten hair

Answer: (B)

Barrier cream creates a protective layer on the skin around the hairline and ears to shield it from the chemicals in perm solutions and neutralizers. Perming uses strong reducing agents that can irritate or burn skin on contact, so this cream helps prevent burns and dermatitis by keeping those chemicals away from the skin. It’s applied to the skin, not the hair, and doesn’t affect the rods or the processing time. It also won’t lighten the hair. The cream’s main job is skin protection, contributing to a safer, more comfortable perm service.
