Face Analysis and the Golden Ratio: A Guide for Hairdressers

The harmonic canon isn't a screen to show: it's one step inside a flow that starts with a photo and ends in the protocol. Its value lies in how it connects to everything else.

The flow, not the screen

Capture comes first and it's the step that decides the quality of everything after: front-facing photo, head straight, even light, gaze level with the lens. A crooked photo produces wrong proportions, and a reading built on wrong measurements is worse than no reading.

The reading is then shared, not handed over. You show two or three ratios — not all of them — and say what they mean: where a length will move the eye, which line a layer will highlight. That's the moment the client goes from spectator to participant.

The step that closes the flow is translation into the plan. A proportion recorded that doesn't appear in the reasoning behind the proposal and in the protocol stays a useless piece of data: it looked like technology, it changed nothing in execution.

Important: the photo lives only inside the consultation session and the reading doesn't produce a score for the face.

Where the value of the analysis is most often lost

The chart is qualitative and shows how far skipping each step cancels the benefit of the analysis.

Isolated analysis and analysis in the flow

The table compares what changes depending on whether the reading stays a moment of its own or is connected to the rest of the consultation.

Connecting it to the rest

01

Take care with capture

Front-facing, even light, head straight.

02

Share the reading

Two ratios, not the full output.

03

Translate into the proposal

The measurement has to justify a choice.

04

Carry it into the protocol

The criteria, not the numbers.

How to connect it to the rest

  • Take care with capture: it decides the reliability of everything.
  • Show two ratios, not the whole output.
  • Carry the criteria into the protocol, not the numbers.

Carrying criteria rather than numbers is what makes the protocol readable. «Length below the jaw so as not to underline the angle» is an executable instruction; a list of decimal ratios isn't, and it will be ignored in the back room.

At the next visit the previous reading becomes the starting point. There's no need to redo it if nothing has changed: what's needed is to compare what was decided with how it turned out, which is a far more advanced conversation than the initial one.

Where Saloria fits in

From discourse to guided consultation

Saloria integrates proportional readings into the flow, translating them into understandable cut and colour suggestions. It doesn't replace management software, doesn't promise realtime AR and doesn't turn look plan into certainty. It brings method to the moment when client and professional decide the look together.

Frequently asked questions

Does the analysis need redoing at every visit?

No. Proportions change slowly: the reading is redone after a significant change or after some time, not at every appointment.

What happens to the photo?

It's used during the session and deleted according to the configured retention, with consent collected before the shot.

How much data should you show the client?

Two or three ratios, tied to concrete consequences. The full output turns the consultation into a measurement exercise.
