Henna, an Old Keratin Smoothing, and a Request for Bone-Straight
A client with tightly coiled 4C hair books a silk press. At consultation she mentions three things in passing: she applied a henna-and-indigo gloss she bought online about three weeks ago, she had a "keratin smoothing" treatment at another salon roughly three months ago (she does not know the ingredients), and she has a box of no-lye relaxer at home that she wants the culturist to apply today so the press "takes better." She has a wedding in five days. Her hair is currently dry, with visible mid-shaft breakage and a slightly rough cuticle feel in the crown. She is impatient and says a friend's stylist "just did it" with no problems.
1. Explain the chemical risks that make this a high-risk service, and what you would refuse or postpone.

Reasoning: The risk here comes from unknowns stacking on each other, not from one product.
- Henna compounds: Pure henna is a plant dye, but imported or "compound" henna preparations may contain metallic salts and other additives. Those can react unpredictably with relaxers and other alkalis, producing heat, discoloration, and severe breakage. You cannot verify what was in an online product.
- Unknown keratin smoothing: These treatments vary widely; some involve formaldehyde-releasing ingredients or protein/aldehyde systems that leave the hair's chemistry changed. Without the ingredient list or the prior stylist's protocol, you cannot predict compatibility.
- Relaxer on top of both: A no-lye relaxer is strongly alkaline and swells and restructures the fiber. Applying it over an unidentified smoothing treatment and a henna gloss, on hair already showing mid-shaft breakage, risks irreversible damage right before a wedding. Refuse applying the relaxer today. You may offer the silk press alone if a strand test is acceptable, and you should say why the refusal protects her event rather than spoiling it.
2. If the client accepts a modified plan, describe the pre-service testing and the press protocol you would use, with the reasoning behind each step.

Pre-service: Obtain the henna product name or a photo of the label if possible, and ask her to request the smoothing treatment record from the other salon. Perform a patch test on skin and a strand test on a shed or hidden section at least 24–48 hours ahead where time allows; a strand test is the only practical way to observe an unpredictable reaction before it is on her whole head. Note her breakage and rough cuticle in the record.
Press protocol:
- Clarify gently to remove buildup, then condition with attention to mid-shaft porosity; do not over-proteinize hair that already feels rough and dry.
- Dry thoroughly - moisture trapped under heat is what causes "bubbling" and steam damage.
- Apply a heat protectant and use the lowest effective temperature, tested on the strand first. Fine, porous, or chemically altered hair scorches at temperatures healthy virgin hair tolerates.
- Work in small sections, one or two passes, and stop at the first sign of smoke or a burnt smell.
- Skip flat-ironing the most fragile mid-shaft if it is already compromised. Document settings and products. Offer a trim of the damaged ends rather than promising repair.
3. The client insists: "My friend had no problem - just do it." How do you respond, and what belongs in the record?

Response: Client autonomy means she can choose to have the service elsewhere; it does not obligate you to perform a service you judge unsafe. Say it plainly and without moralizing: "I can't predict how that relaxer will react with the henna and the smoothing treatment, and if it goes wrong five days before your wedding there is no fix. I'll do the press today, or I'll help you find a stylist who will do the chemical service after a strand test."
Offer a concrete alternative and a timeline - for example, relaxing weeks after the wedding once the hair has been assessed and the prior products identified. Do not perform the service "under protest" with a signed waiver; a waiver does not make an unsafe chemical decision defensible, and it does not transfer the professional duty of care.
Record: date, the products disclosed by the client, the unknown keratin treatment, the condition observed (dryness, mid-shaft breakage, rough cuticle), the risks explained, the service declined and why, alternatives offered, the client's decision, and a signed acknowledgment of the consultation. Write it contemporaneously, in neutral language.
