The Black Henna Client Who Wants Honey Blonde
A client arrives with a box of 100% natural black henna that she says was applied six weeks ago at a village fair. She wants a global honey-blonde colour for her sister's reception in five days. Her hair is dry, the mid-lengths are rough, and the ends have a faint greenish tint in daylight. She had itching and a red patch behind her ear after a colour two years ago. Your salon uses a 20-volume oxidative colour and a powder lightener. You do a strand test: after 20 minutes the test strand turns greenish-grey, feels gummy and breaks when pulled gently. The client insists that natural henna is safe and asks you to proceed because she has already paid a deposit. Your salon keeps a colour record card and a patch test policy requiring 48 hours.
1. Interpret the strand test and explain the chemistry behind the result in terms the client can understand.

The strand test shows incompatibility. The greenish-grey colour, gummy feel and breakage after only 20 minutes mean the hair cannot withstand oxidative lightening in its current state.
Why: so-called black henna is often not pure plant henna. It may contain metallic salts or indigo, and even pure henna coats the hair and binds to keratin. When a bleach or oxidative colour is applied over metallic salts, the chemicals can react strongly, sometimes producing heat, smoke or burns, and the hair can melt or break. The greenish tint suggests a reaction between the existing pigment and the lightener.
Reasoning: a strand test is done precisely to predict this before the whole head is treated. Ignoring a failed test would risk chemical burns to the scalp, severe hair breakage and a complaint the salon could not defend. The client's belief that natural means safe does not override the test result.
2. State what you will and will not do, including patch testing, and give two safe options.

Will not do: no bleach, no global oxidative colour, no high-lift tint. Proceeding would be negligent given the failed strand test.
Will do: record the strand test result and explain it. Offer a 48-hour patch test for any alternative product, because she has had a reaction to colour before; a previous itch is a warning sign, not proof that every product is safe.
Safe options:
- A trim to remove the most damaged ends, plus intensive conditioning and a glossing treatment that does not lift colour, only after a patch test and strand test.
- Wait until the henna has grown out or is cut out, then reassess with a strand test before any lightening. Temporary spray or root touch-up colour can be discussed after testing.
Reasoning: the only responsible route is to work with the hair's actual condition. A patch test and a strand test protect her scalp and the salon.
3. How would you handle the deposit and the conversation so the client does not feel cheated?
Read the worked answer
Explain the result first, in plain language, and show her the test strand so she can see and feel the gummy breakage. Say clearly that you are refusing the bleach because it could burn her scalp or break her hair, not because you do not want her business. Offer to transfer the deposit to a conditioning and trim service, or refund it according to the salon's written policy; check that policy before promising.
Give her a written note of the strand test result and the advice, and book a review in a few weeks. If she still wants to go elsewhere, do not argue; tell her to ask that salon to do a strand test first. Record the refusal, the deposit decision and her response, and ask her to sign.
Reasoning: transparency and a fair deposit decision reduce the chance of a public complaint. A written record protects the salon if another salon causes damage and she blames you.
