What do nails really cost? The whole bill

Nails are not a one-off purchase. They are a subscription with irregular instalments, which is exactly why the question "what does a set cost" so often leads nowhere. What matters is not the price of one appointment but which items come up how often, and how they relate to each other.

Those relationships turn out to be remarkably stable across cities, countries and currencies. The absolute figures are not. So this article puts the structure of the bill first; the amounts you collect yourself, from two salons near you.

Almost every price list carries two numbers: one for a full new set and one for an infill. Both are quoted for the standard case — short to medium length, one colour, no dramatic extension past the fingertip, no design. Everything beyond that either sits further down the list or is not on it at all.

The base price normally includes preparing the natural nail, the product itself, building, shaping and filing, one colour or a plain top coat, and the oil at the end. That is more work than it sounds. Most of the appointment is preparation and filing rather than the build, which is why what you are paying for here is time far more than material.

What is almost never included is removing someone else's work — a set that was not built in this salon. That is not a trick, it is a time problem: if nobody knows what product is on the nail, the work has to be slower and more careful.

And one item is missing from every list even though it explains most of the difference: the length of the slot. Two salons with identical list prices may set aside sixty minutes or ninety for the same service. The price per appointment is then the same and the price per hour is not — and the hour is what you actually mean when you compare.

The underlying structure is the same wherever you book. The new set is the most expensive single item and the reference point for everything else; the infill sits well below it; repairs, removal and surcharges land as fractions in between.

For a sense of scale: in US salons a full new set usually runs somewhere between 60 and 100 dollars and an infill between 45 and 70, with city centres sitting at the top of both. Treat those as ranges to ask about rather than as quotes — rates vary sharply by region.

Now the sum nobody works out. At one appointment every two and a half weeks you are looking at a good twenty visits a year. Three of them are new sets, the rest infills. Over twelve months that adds up to roughly sixteen times the price of a single new set. That is the number that actually matters, and it appears on no price list anywhere.

Something very practical follows from that. A salon that is two dollars cheaper on the infill saves you more across the year than one that is ten dollars cheaper on the new set. When you compare, look at the line that comes up most often, not the line that looks biggest.

The surcharges are not small print. They all follow the same principle: they buy extra time and extra product. Knowing which of them apply to you turns a vague range on the phone into a firm number.

• Length: Past the fingertip, pricing is usually tiered in two or three steps. Each step needs more product and more reinforcement at the stress zone.
• Shape: Round and oval are the default. Ballerina, stiletto and sharp edges carry a surcharge because they are slower to file and forgive fewer mistakes.
• Overlay with no extension: A builder layer on your own nail sits between gel polish and a full set — in what it does and in what it costs.
• Nail art: Nearly always charged per nail rather than per appointment. Two accent nails barely register; ten elaborately worked ones can come close to doubling the appointment.
• Repairs: A single nail between two appointments is its own line item. It is small, but on some hands it happens regularly, and then it belongs in the annual sum.
• Removal: Charged when nothing new is being built, or when the product came from another salon. Within the same appointment as a rebuild it is often included.

What barely moves the price, by contrast, is the choice between gel and acrylic. The two systems sit at almost the same level nearly everywhere. The difference comes from length, shape and design, not from the material.

A low entry price is not automatically a bad deal. It only becomes expensive when it is made possible by one of three things — and all three can be spotted in advance.

The first is time. A set with sixty minutes booked instead of ninety saves those minutes somewhere, and what gets cut is almost always the preparation, because nobody can see it afterwards. You see it three weeks later, as lifting edges. Every lifted nail is either a repair or a new set brought forward, and both cost more than the half hour that was saved.

The second is scope. If the advertised price excludes removal and you arrive with product still on your nails, the appointment ends up being two items long. That is entirely fair as long as it is said beforehand. Which is why the question belongs on the phone, not at the till.

The third is the tie-in. A very cheap first appointment is betting that you come back for infills — and the infill is the line that comes up twenty times a year. So always look at both numbers before you book. A salon that gives the first visit away and prices infills above the local norm is the more expensive one over twelve months.

These five questions take under two minutes on the phone and spare you the surprise at the till. None of them is awkward, and a good salon answers all of them without hesitating.

• Does that price cover the length I want? Give a rough length or a shape when you ask — that is what decides the tier.
• Is removal included? And does it change anything that the set was built somewhere else?
• Is nail art charged per nail or per appointment? Ask what two accent nails come to while you are at it — that is the common case.
• What does a repair between appointments cost? And can I get a slot for one at short notice?
• How long is the appointment booked for? The answer tells you more about how the salon works than any number on the list.

And when you are weighing up two salons: compare the infill and the time booked for it. That is the item that repeats, and the time is what you are really paying for.
