Which action performed before a perm may cause scalp irritation?

• A. Brushing Hair
• B. Washing Hair
• C. Conditioning Hair
• D. Heat Styling

Answer: (A)

Mechanical irritation of the scalp from brushing before a chemical service can lead to irritation during processing. Brushing vigorously creates friction that can rub and abrade the scalp, producing tiny injuries or heightened sensitivity. When the perm solution is applied, those irritated areas are more prone to burning, stinging, or inflammation. To minimize this risk, detangle gently with a wide-tooth comb and avoid aggressive brushing right at the scalp. Washing or conditioning are normal prep steps and are generally not irritating when done softly, and heat styling isn’t part of the prep during a perm, though it can dry or stress the scalp. The key idea is that mechanical irritation from brushing can predispose the scalp to discomfort during chemical processing.
