Show answer & explanationAnswer & explanation
Correct answer: B. Protect the client's scalp and hairline with a protective base cream.
Sodium hydroxide relaxers are highly alkaline and can cause severe burns if they come into direct contact with the skin. Applying a protective base cream is crucial to shield the scalp and hairline from chemical irritation.
Why the other options are wrong
- A. Metal combs can react with chemicals or scratch the scalp, increasing the risk of irritation or injury during a chemical service.
- C. Processing under a hooded dryer can intensify the chemical reaction, potentially leading to over-processing and scalp burns.
- D. Applying relaxer directly to the scalp can cause irritation or chemical burns due to its high alkalinity.
