"How much is it?" - the question that cannot be answered and must be

Refusing to publish is itself an answer

A client who finds no prices concludes one of two things, and neither is the one you want: that it is expensive, or that there is something to hide. Meanwhile the salon down the road has published a range, and the comparison is happening whether you take part or not. The question is not whether to publish but what the honest publishable unit is.

Publish the structure, not a single number

"Colour from X, and here is what moves it: length, density, and whether there is existing colour or lightening to work around" is both true and useful. It tells a client whether they are in the right place, it tells them why a consultation exists, and it cannot be quoted back at you as a promise. Most salons already know these factors perfectly well and have simply never written them down in the order a client would ask.

Separate the price question from the suitability question

A good share of price enquiries are not really about money - they are about whether the treatment is right for this person at all, asked in the only vocabulary they have. "How much is microneedling" from someone who should not have microneedling is a question about suitability. An answer that gives a number and nothing else has answered the wrong question and may have sold the wrong treatment.

What software should and should not say about price

It can repeat what you have published, including the structure and the factors - that is accurate and it is available at ten in the evening when the client is actually looking. It should not estimate a specific client's price from a description of their hair or skin: that is a judgement made in person under light, and a number produced at a distance becomes an expectation you have to argue with at the chair. Whether price is mentioned at all should be a setting you control.
