Nobody quotes a client for gel, which is exactly why it drifts. Consumables priced by the tub and consumed by the installation are the classic silent margin leak in a braiding studio — and the fix costs one afternoon of measurement.
1. Turn the Tub Into a Unit of Service
Weigh a full tub. Then dispense in a fixed portion — a level 5g scoop or a calibrated pump — and count how many portions the tub returns. That converts a container price into a cost per portion, which is the only figure you can attach to a service line.
Do it separately for gel and for wax. They are consumed at very different rates: gel goes across the whole head, wax is usually concentrated at the hairline, parts and the finishing edges.
2. Realistic Consumption per Service
Track consumption across three service types you actually sell — for example a full-head loc retwist, a boho braid installation, and a touch-up. Record portions used, not "a bit". After ten clients you will have a per-service average that is stable enough to price against.
The point is not to charge the client for gel. The point is to know that your quoted price includes a known consumable cost, so a supplier price rise is a decision you make rather than a surprise you absorb.
3. Cheap Gel Is Expensive Rework
A low-cost gel that flakes at the hairline generates complaints, and a complaint costs you far more than the difference between two tubs. Flaking, white residue and weak hold all show up two to five days after the appointment — which is precisely when the client decides whether to rebook.
When you switch gel, run a side-by-side on two clients with similar hair density and texture in the same week, and judge on day three and day seven. Hold that survived the first wash matters more than hold in the chair.
4. Put It in the Quote Sheet
Once you know cost per installation, add one line to your internal quote sheet for consumables. Most studios find it is a small percentage of the service price — but it is a percentage that compounds across every chair, every week, and it is the first place a price rise should be absorbed rather than passed to the client.
