Shampoo Selection for an Irritated, Flaking Scalp
A 28-year-old client arrives with visible white flakes on her dark shirt, an itchy scalp, oily roots, and dry, heat-straightened ends. For three weeks she has used a charcoal clarifying scrub daily and a new peppermint ‘tingling’ shampoo, and she now wants a scalp scrub plus a hot-oil treatment before her color service. Her hairline is mildly red, but there are no open sores, thick silvery plaques, or pus. She uses topical benzoyl peroxide for acne and says her scalp ‘needs to breathe.’ The shop has a fragrance-free mild shampoo, a pyrithione zinc shampoo, a moisturizing conditioner, a silicone scalp brush, and a steamer. The barber must decide whether the scrub and hot oil are appropriate today, what cleansing and conditioning approach will calm the scalp without over-drying the ends, and what to tell her about proceeding with color if the redness persists.
1. Are the scalp scrub and hot-oil treatment appropriate today? Explain your reasoning.

Not in the requested form. The pattern-white flakes, itchy scalp, oily roots, mild hairline redness, and three weeks of daily clarifying scrub plus a tingling peppermint shampoo-suggests irritation or over-cleansing and possibly seborrheic dermatitis rather than simple dry scalp. A gritty scrub can further irritate inflamed skin, and hot oil or a steamer can worsen heat and occlusion on an already red scalp. The barber should skip the scrub and hot oil today, use gentle cleansing, and avoid vigorous massage or essential-oil ‘detox’ products. Because there are no open sores, pus, or thick plaques, a mild service is reasonable, but persistent or spreading flakes need medical referral. Document the observation and recommendation.
2. Recommend a shampoo/conditioner plan and application technique that addresses the oily roots and dry ends.

Use a mild, fragrance-free or low-surfactant shampoo on the scalp, diluted if needed, and stop daily use of the charcoal clarifier. A pyrithione zinc shampoo can be used two to three times weekly if the flaking is mild and the client is not allergic; otherwise alternate with the mild shampoo. Apply shampoo mainly to the scalp, massage with fingertips-not nails-for under a minute, and rinse with lukewarm water. Apply conditioner from mid-shaft to ends only; keep it off the inflamed hairline. Blot, do not rub, with a towel. Recommend reducing heat styling and spacing washes. If redness, itching, or flakes worsen, refer to a dermatologist; barbers do not prescribe medicated treatment.
3. The client still wants color today. What is your decision and what do you tell her?
Read the worked answer
Postpone the color if the scalp is still visibly red or irritated. Color on compromised skin increases stinging, chemical burn risk, and uneven results, and the benzoyl peroxide she uses can make skin more sensitive. Explain that the scalp needs to calm down first; offer a conditioning service and rebook the color in several days. If the redness has resolved and she insists, do a patch test at least 24–48 hours ahead per manufacturer and shop policy, protect the scalp, use a gentle formula, and avoid overlapping lightener on the scalp. Do not promise a result on irritated skin. Document the advice and her choice.
