Scalp Lesions Before a Relaxer Service
Marisol, 34, books a virgin relaxer and a single-process color for a wedding in three days. During the consultation she mentions she applied a box dye two weeks ago. At the hairline and nape you see several red, raised, tender bumps; one is open and weeping. Her hair is dry and porous, snaps when wet, and she admits to daily clarifying shampoo and no conditioner. She has a general service consent but no medical history form. She says the bumps are 'just from the dye' and asks you to 'work around them.' She is taking an acne medication and cannot remember the name. The salon policy says chemical services require a patch test 48 hours ahead, but she is a walk-in. Another stylist says she can squeeze her in after a haircut.
1. What are the red flags, and can you proceed with the relaxer and color today? Explain your decision and what you would say to Marisol.

Do not proceed. The open, weeping bumps are a break in the skin barrier, and a high-pH relaxer or oxidative color over that area can cause chemical burns, infection, and scarring. You are not permitted to diagnose the bumps, but you can recognize that the scalp is not intact and refer her to a physician. The recent box dye is an unknown formulation, and the salon's 48-hour patch-test policy has not been met; a patch test does not make an open scalp safe. The possible acne medication is also a red flag: if it is isotretinoin, healing is impaired and sensitivity is increased, so you need the exact medication and physician clearance. The hair's wet-stretch result (snaps) shows poor elasticity, so even without the scalp issue the hair is a poor candidate for same-day relaxer plus color. 'Working around' the lesions is unsafe because product, rinse water, and fumes migrate. Offer only a gentle shampoo/style if the scalp can tolerate it, or reschedule after the skin heals, the medication is identified, and a patch test and strand test are done. Document the refusal and referral.
2. Once the scalp has healed, how would you determine whether her hair can tolerate a relaxer, and what would you change about the service plan?

First obtain medical clearance and the exact medication history; confirm the scalp is intact and free of tenderness. Do a 48-hour patch test per salon policy, then a strand test on a hidden section using the exact relaxer and developer. Assess elasticity with a wet strand: if it stretches and does not return, the cortex is compromised. Check porosity along the shaft, because the box dye and daily clarifying shampoo have likely created uneven porosity. Do not relax and color on the same day; separate them by at least two weeks, and do not overlap the relaxer onto previously colored hair. Use the mildest relaxer that will do the job, apply to new growth only, and protect previously processed hair with a barrier. Add a protein/conditioning schedule and stop daily clarifying shampoo. If the strand test is questionable, refuse the relaxer and offer a conditioning/trim plan. Re-test before every chemical service because her history is cumulative.
