What is the purpose of applying base cream around the hairline and scalp?

• A. To protect the skin from chemical burns at the hairline and on the scalp during treatment.
• B. To color the scalp.
• C. To moisturize the hair.
• D. To speed up processing.

Answer: (A)

The main concept is protecting the skin from chemical burns by using a base cream as a barrier around the hairline and scalp during chemical treatments. Placing a barrier cream along the hairline and scalp keeps the chemical away from the skin, reducing the risk of irritation or burns that can occur when strong solutions are applied close to sensitive areas. It also helps prevent staining of the skin in those areas and makes cleanup easier.

This isn’t about coloring the scalp, moisturizing the hair, or speeding up processing. Those functions aren’t achieved by base cream; its purpose is safety and comfort by creating a protective shield between the chemicals and the skin.
