How long to book for colour, balayage and highlights
Book colour by the real time in the chair: roots, full colour, balayage and colour corrections each need their own slot. How to set lengths without overruns.
7 min read
Book colour by the time the client really spends in your chair, not by the name of the service. Roots, a full colour, foils, a balayage and a colour correction are different jobs: give each its own service and its own slot length, add the processing time and the finish, and keep long colours for the parts of the day where an overrun won't wreck everything after them. Ask for details (length, previous colour, photos) before the appointment so a "quick colour" doesn't turn into a three-hour correction.
Why colour days run late
Cuts are predictable. Colour isn't, and it's usually colour that pushes a salon day back. The same few reasons come up again and again:
- One word, many jobs. "Colour" can mean a root touch-up or a full head on long, thick hair. Booked in the same slot, one of them will overrun.
- Processing time forgotten. The slot covers the application but not the time the colour sits, the rinse, the toner and the blow-dry.
- Hair history unknown. Box dye, old henna or previous highlights change everything, and you only find out once the client is sitting down.
- Hair length and density. The same balayage on a chin-length bob and on hair to the middle of the back aren't the same appointment.
Split colour into separate services
The first fix is on your menu. Instead of one "colour" service, list the jobs you actually do, each with its own time. The durations below are starting points to adjust to your own speed, products and clientele; what matters is that each one is written down and used every time.
| Service | Typical slot | What the slot includes |
|---|---|---|
| Root touch-up | 1 h 30 | Application, processing, rinse, blow-dry |
| Full colour | 2 h | Full application, processing, finish |
| Half head of foils | 2 h | Sectioning, foils, processing, toner, finish |
| Full head of foils | 2 h 30 – 3 h | As above, on the whole head |
| Balayage | 3 h | Painting, processing, toner, cut or finish |
| Colour correction | Consultation first, then half a day or more | Depends on the hair's history |
For long or very thick hair, create a separate "long hair" version of the service with a longer slot, rather than hoping the standard one will stretch.
Count every step, not just the application
Time one of your colours from start to finish: consultation at the chair, sectioning, application, processing, rinse, toner, treatment, cut if included, blow-dry. The total is your slot. If you usually take another short client during processing time, that's fine, but plan it deliberately: open a short slot for a cut or a blow-dry inside the colour client's processing time, rather than assuming it will fit.
Ask for details before the appointment
Many colour surprises can be spotted in advance. When clients book online, ask them in the service description to add a short note with:
- their hair length (short, shoulder, long);
- what's on their hair now (natural, salon colour, box dye, henna, highlights);
- what they want, ideally with a photo sent by message after booking.
If the note mentions box dye over highlights or a big change from dark to light, call the client before the day and move them to a colour correction consultation. It's a two-minute conversation that saves an afternoon.
Offer a consultation for big changes
For colour corrections, going much lighter, or first-time balayage on long hair, a short free consultation is worth its time. You see the hair, do a strand test if you need one, agree on the result and the number of sessions, and then book the real appointment at the right length. Clients also appreciate knowing the price range before they commit to a long session.
Place long colours in the day
A three-hour balayage starting at 4 pm on a Saturday leaves no room for anything to go wrong. Many hairdressers keep long colour services for the morning or early afternoon, and leave the end of the day for cuts and blow-dries that are easier to predict. You can make that a rule simply by opening balayage slots only in the mornings, and cut slots later.
Check and adjust
For a few weeks, note when each colour client actually leaves compared with the end of their slot. If balayages keep finishing thirty minutes late, lengthen the slot. If root touch-ups always finish early, shorten it and gain a slot a day. The goal is a column of bookings that matches reality, so your last client isn't the one paying for everyone else's overrun.
Should roots and full colour be separate services?
