Relaxer Two Weeks After Highlights
A 17-year-old client wants a relaxer four weeks before her school prom. She had foil highlights two weeks ago and her natural hair is wavy and medium density. At the nape there is a 3 cm area of broken hair, and the mid-lengths feel rough and porous. She has a 1 cm graze on the scalp near the hairline, caused by combing. A strand test shows high porosity and poor elasticity. She used a box relaxer five months ago and says her hair "went frizzy" afterwards. She wants smooth, straight hair and has brought a photograph of a sleek, blunt style. She is willing to sign anything to have the service today.
1. Explain what is happening at hair-structure level and why a relaxer now is high risk.
Read the worked answer
Hair is mainly keratin arranged in a cortex surrounded by a cuticle. Relaxers are strongly alkaline and break disulfide bonds in the cortex so the hair can be straightened. Lightener also damages the cuticle and cortex and leaves the hair more porous. Applying a relaxer over recently highlighted hair means the alkaline product can penetrate unevenly, break more bonds and cause further cuticle loss.
The graze is a separate contraindication: a broken scalp surface allows chemical irritants and infection to enter. The strand test - high porosity and poor elasticity - shows the hair is already structurally compromised. The previous box relaxer adds overlap risk. The likely outcome is breakage at the nape and mid-lengths, not the sleek result in the photograph.
2. Would you proceed? Set out a safe plan for the next four weeks and explain how you would manage the client's expectations.

Do not proceed with the relaxer today. Explain clearly that the graze must heal and the hair needs strengthening; a chemical straightener now could cause irreversible breakage. Offer a patch test and strand test for future reference, but do not use the client's willingness to sign a disclaimer as consent to unsafe practice.
For the next four weeks: treat the hair with protein and moisture treatments, trim the broken nape area, and avoid heat and further chemicals. For the prom, offer a blow-dry, roller set or heat-free styling with a protectant. If she still wants straightening later, reassess elasticity and porosity, wait until the scalp is fully healed and the highlighted hair has grown or been trimmed, and perform a strand test. Do not promise a relaxer on a fixed date; explain that chemical services are decided by hair condition, not by the calendar.
3. What aftercare and home-care advice should be given, and what should be recorded?
Read the worked answer
Advise a gentle sulphate-free shampoo, a moisturising conditioner and a weekly deep treatment, applied mainly to mid-lengths and ends. Detangle with a wide-tooth comb, avoid tight ponytails and heat tools, and use a heat protectant if styling. She should not use a home relaxer kit, and should wait for professional assessment before any further colour or straightening.
Record the consultation, the scalp graze, the strand-test result, the refusal of service, the styling alternative offered and the client's response. Note that she was advised not to treat the hair chemically at home. If she reports burning, broken areas or scalp pain, advise her to see a pharmacist or GP.
