Client and service
What belongs on a hair color formula card?
A useful formula card identifies the client and service date, records exact shades and quantities, names the developer and mix ratio, notes the technique and processing time, then separates today’s observed result from the adjustment planned for next time. Record allergies or sensitivities clearly, but do not use the card as medical advice.
Why separate result and next-time notes?
The result describes what happened today. The next-time note turns that observation into a specific adjustment. Keeping both prevents an old plan from being mistaken for a finished result.
