Burning Scalp During a Relaxer Retouch
At 4:15 p.m. on a Friday, a three-stylist salon is fully booked. The ceiling extractor fan has been out of service for two weeks; the manager has propped open the fire door. A client arrives for a sodium hydroxide relaxer retouch. She mentions she had a "little sting" with a previous relaxer, but no patch test is done. The relaxer is applied to the scalp and ends; eight minutes later she complains of intense burning and the scalp looks red and weepy around the hairline. The salon has one shampoo bowl, two stained towels and a box of nitrile gloves that staff wear only when mixing. A junior stylist wants to rinse the relaxer immediately; the senior stylist says to wait because "the timer has four minutes left". Two other clients are in the salon.
1. What should be done in the first ten minutes, and who should take charge?

The senior stylist should take charge and stop the service at once. The client's report of intense burning plus red, weepy skin is a chemical burn, not normal tingling, so the timer is irrelevant. Put on clean nitrile gloves, move the client to the shampoo bowl and rinse the scalp with copious lukewarm running water for at least 10–15 minutes, parting the hair so water reaches the hairline and nape. Do not scrub or apply vinegar or other homemade neutralisers; the priority is dilution and removal. Shampoo gently if the salon protocol allows, then blot with a clean disposable towel. Do not apply another chemical or tight style. Record the product name, batch, mixing strength and time applied. Advise the client to seek medical assessment the same day, give written aftercare and arrange follow-up. Meanwhile, another staff member should ventilate the room, remove contaminated towels and keep the other clients away from the wet area. The junior stylist's instinct to rinse immediately is correct; delaying to complete the timer increases tissue damage.
2. Identify the root causes in this salon and propose controls that would prevent recurrence.
Read the worked answer
The immediate cause is that a strong alkali was left on a client with a previous reaction and no patch test. Contributing causes are a broken extractor fan, use of a propped fire door as ventilation, gloves worn only when mixing, insufficient clean towels and only one shampoo bowl for a fully booked salon. Controls should be layered. Engineering: repair the extractor and keep it serviced; do not rely on a fire door for routine ventilation. Procedural: carry out a patch test at least 48 hours before any relaxer and ask about previous reactions; check the scalp for abrasions, sores or tenderness and decline service if present; follow the manufacturer's maximum processing time and never leave a client alone with burning. PPE: gloves for mixing, application and rinsing; apron and eye protection as needed. Administrative: train all staff to recognise burns, keep Safety Data Sheets, stock enough clean towels and schedule chemical services so the shampoo bowl is free. The salon should also review staffing levels so a junior is not left to manage a reaction while the senior protects the timer.
3. What should be documented, and what should the client be told before leaving?
Read the worked answer
Documentation should be factual and completed before the client leaves: client details, date and time, product name and batch, developer strength, application and rinse times, staff involved, the client's earlier reaction report, the lack of patch test, observed symptoms, first aid given, referral advice and any follow-up appointment. Keep the signed consultation record and any incident report required by the salon's insurance or local health authority. A photograph may be taken only with consent and stored confidentially. The client should be told clearly that this was an adverse reaction, that she should see a doctor if swelling, weeping, dizziness or spreading redness occurs, and that she must not have another relaxer or colour until medically cleared and a patch test is done. Give written aftercare: keep the area clean, avoid heat, scratching and tight hairstyles, and do not apply oils or medicated creams unless prescribed. Explain that the salon will investigate and that a senior staff member will follow up. Avoid blaming the client or promising that no scar will form; be honest, apologetic where appropriate and professional.
