Thai Clinic AppA colour formula is the record of what went onto a client's hair at one appointment: which shades in which ratio, which developer, how long, and what came out. It is written once per colour and read before the next one. The same shape of note exists in a massage studio — the oil, the pressure, the area that hurt — even though nobody there calls it a formula.
What a hairdresser writes down
A line like “7/1 + 9/0 in 1:1, 6 % developer, 35 minutes, roots only” is a complete colour formula: the shades from the manufacturer's chart, their ratio, the developer, the time and where it went. Every stylist has her own shorthand. What matters is that a colleague can read it six weeks later and mix the same thing, or see what to change if the result was too warm. Hairdressing software advertises this as a feature because the formula so often lives in one stylist's notebook and leaves with her.
A massage studio rarely needs one — but has the same pattern
A Thai massage has no formula to write down, and it would be odd to pretend otherwise. What a studio does have is the same pattern: what was done last time is the first thing the therapist wants to know this time. Which oil, and whether it caused a reaction. How much pressure the guest asked for, and whether she asked for less halfway through. Which area was worked on, which herbal compress was used, what the guest said at the end. Those are the studio's formula, and they fail in exactly the same way: written on an index card or remembered by one therapist, they are missing the moment somebody else takes the appointment.
Why the note belongs to the visit, not to the guest record
A guest's preferences change: the pressure that was right in January is too much after a back injury in June. One field on the guest record is overwritten each time and loses what came before; a note on the recorded treatment keeps every visit with its date, so the last one is at hand and the one before it is still there. A limit is worth stating plainly: software stores text. The note is only as good as what the therapist writes down, and no tool should be expected to choose the oil or the pressure for her.
In Thai Clinic App the formula — or the oil, the pressure, a note on what was done — is a field of your own on the recorded treatment, created once under customizing. Every recorded treatment then carries its value, and the guest's history shows it with the date, the therapist and the price of that visit, so a colleague finds it where she looks for the treatment, not on a card in a drawer. When the next treatment is recorded for that guest, the last value of the field is already filled in — as last time — and can be kept as it is or overwritten with what was done this time. Nothing is suggested or checked by the software: it keeps what you write and shows it at the next visit. A hairdresser using the same software keeps the colour formula in exactly this field.
Frequently asked
Does a massage studio need a colour formula?
No. Nobody mixes colour there. What a studio does need is the same kind of note — the oil, the pressure, the area worked on — and it goes into the same kind of field on the recorded treatment: shown in the guest's history, and offered again when the next treatment is recorded.
Does the app suggest the oil or the pressure?
No. It stores the text the therapist writes and shows it at the next visit — in the history and as the prefilled value for the next recorded treatment. What is done on the mat stays the therapist's decision.
Why not simply a note on the guest record?
A note on the record holds one value and loses the previous one when it is overwritten. A field on the recorded treatment keeps every visit with its date, and the latest value is still the one offered first — which is what you want when a preference changes.
