The Relaxer Touch-Up After a Box Dye and a Scab
A 34-year-old client, Danielle, arrives at 2 p.m. for a relaxer touch-up before a party at 6 p.m. She had a box dye applied 10 days ago, has a 1-inch scab at her nape from scratching, and used a 'natural' henna gloss two months ago. Her hair feels rough, porosity is high, and a wet strand stretches and snaps. She wants 'bone straight' hair and says she cannot reschedule. The shop has sodium hydroxide relaxer, neutralizer, a keratin smoothing treatment, and a bond-repair mask. You have 45 minutes before your next client. The shop's relaxer kit has no patch-test record for her, and she reports burning during her last relaxer.
1. Should you proceed with the relaxer today? Justify your decision.

No. There are multiple contraindications. The scab at the nape is an open skin injury; applying sodium hydroxide over it can cause a chemical burn, infection, and scarring. The box dye 10 days ago means her hair has already been through an oxidative chemical process, and relaxing too soon increases overlapping damage and breakage. The henna gloss is a wild card: some henna products contain metallic salts that react unpredictably with relaxers, causing heat, discoloration, or severe breakage. Her wet strand snaps, indicating poor elasticity, so the hair cannot safely withstand more chemical processing. She has no patch-test record and reports burning last time, which raises the risk of sensitivity. The 45-minute window is also insufficient for a safe application, smoothing, processing, rinsing, and neutralizing. Reschedule.
2. What tests and timeline would you require before a future relaxer?
Read the worked answer
Wait until the scab is fully healed, ideally with a physician's clearance if it was a chemical burn. Wait at least four to six weeks after the box dye, and longer if the hair remains fragile. The henna is the biggest issue: because you cannot verify its purity, the safe course is to let it grow out and be cut off rather than assuming shampoo will remove it. Do a patch test 24 to 48 hours before any relaxer, and do a strand test for elasticity and porosity. If the wet strand still stretches and snaps, do not relax. If the strand test is acceptable, use a scalp base, protect the previously relaxed ends, follow the manufacturer's processing time, and neutralize thoroughly. Never promise 'bone straight'; explain that overprocessing causes breakage and that relaxed hair still needs conditioning and trims.
3. What service can you safely provide today, and how do you explain the limits?
Read the worked answer
Offer a deep-conditioning or bond-repair treatment, a trim of split ends, and a blow-dry or heat-free style that will look polished for the party. Avoid the keratin smoothing treatment today if it contains a chemical straightener or formaldehyde-releasing ingredient, because her scalp is compromised and her hair is already chemically treated. Explain clearly: 'Your scalp has an open area, your hair is showing poor elasticity, and the henna makes the relaxer unpredictable. If I proceed, you could lose length or get a chemical burn. I can condition and style it today, and we can plan the relaxer after your scalp heals and the henna grows out.' Give her a written plan with dates and a patch-test appointment.
