Why the difference matters
In lash and nail studios the same client can come in for two different services: a fill or a new set. The first is shorter and cheaper, the second longer and more expensive. The trouble starts when a client books a fill and, once in the chair, it turns out they really need a new set.
At that point the master has to choose: run late for the next client, rush the work, or explain that today they can't do what's needed. All three are uncomfortable for everyone. Most of these situations can be prevented with a simple rule and a clear service menu.
Write down a clear rule for when a fill becomes a new set
The most common measure is time since the last visit. For example, many studios accept lash fills within two to three weeks and nail fills within three to four weeks. Your numbers may differ. What matters is that they're written down and the same for every master.
Besides time, you can add a second measure, for example: if less than half of the set is left, it's a new set. Word the rule so clients can judge it themselves:
- "Fill: up to three weeks after your last visit."
- "If it's been more than three weeks, or your last set was done elsewhere, choose a new set."
- "Not sure? Message us and we'll help you choose."
Don't forget clients coming from another studio. Many masters prefer not to fill someone else's work, and that's also worth saying up front.
Make them separate services on your menu
If your menu only says "Lashes" or "Gel manicure", the client doesn't know what to pick, and you don't know how much time to hold. It's better to have separate services, each with its real duration and price:
- Fill: a shorter duration and a lower price.
- New set: the full duration.
- Removal: on its own, or as part of a new set when the client comes from another studio.
Keep the names short and clear, without trade jargon. Set durations by how long the service really takes, not by your best day. If your masters work at different speeds, reflect that on the menu too.
Help clients choose correctly when they book
A rule doesn't help if the client never sees it. Put it where people book: in your Instagram bio, next to your booking link, in your saved stories. A short line like "More than three weeks? Choose a new set" works better than a long explanation.
When a client books by message, don't just ask "What would you like?" Ask "When was your last visit, and with whom?" The answer already tells you which service to book.
What to do when the chair reveals a new set is needed
Even with good rules, it will happen sometimes. What matters is that every master handles it the same way and the client doesn't feel punished. Agree on three steps in advance:
- Check the schedule. If the next slot is free, do a new set and charge for it, telling the client before you start.
- If the next slot is taken, offer to do what's possible today and book the new set for the nearest convenient time.
- Explain calmly, pointing to the written rule rather than the master's personal opinion.
If it keeps happening with the same client, book them for a new set next time yourself, or agree on a shorter gap between fills.
Book the next fill before the client leaves
The easiest way to get a client back at the right time is to book the next visit today. The master knows when the fill is due and can offer two or three times within your rule straight away. That way a fill stays a fill, and your day stays predictable. We've written about this in more detail: how to book the next visit before the client leaves.
