To prevent scalp irritation during chemical services, which actions should be avoided?

• A. Shampoo
• B. Brush
• C. Massage
• D. All of the above

Answer: (D)

During chemical services the scalp is more vulnerable, so the goal is to minimize any irritation from both chemicals and mechanical action. Shampooing the scalp during processing can spread chemicals and disrupt the treatment, potentially causing irritation or over-processing. Brushing the scalp introduces friction and can create microabrasions, which increase sensitivity and the risk of irritation. Massaging the scalp can elevate circulation and heat and may drive chemicals deeper or onto areas that should remain less exposed. Because each of these actions can provoke irritation when chemicals are on the scalp, all of them are best avoided during chemical services.
