Lash extensions are a subscription business disguised as an appointment business. The first set is the acquisition; the infill cycle every two to three weeks is where the revenue actually lives. Software for a lash studio has to be built around that cycle or it is just a calendar.
Quick answer
Lash and brow studio software manages the infill cycle that lash businesses run on: booking full sets and infills as distinct services with different durations and prices, tracking each client's infill interval and prompting rebooking before retention drops, recording patch tests and allergy history, and paying per-artist commission. LABÉAU covers all of it with WhatsApp reminders, rebooking prompts, per-artist commission and LHDN/IRAS e-invoicing from RM174.92/month; GlossGenius and Fresha suit solo artists overseas, while TunaiPro is a cheaper single-outlet Malaysian option.

Full sets and infills are different products
A full set takes two to three hours; an infill takes forty-five minutes to ninety, depending on how much has shed and how long the client left it. Pricing, duration and profitability differ completely, and a client who books an infill after five weeks is really booking a partial set.
The system should treat them as separate services with their own durations and prices, and should be able to price an infill by elapsed time since the last visit rather than by a single flat rate — because the artist's time genuinely varies with it. Studios that price all infills identically subsidise their least disciplined clients with their most loyal ones.
The infill interval is the business
Lash retention is measured in weeks and the economics follow it exactly. A client on a consistent two-and-a-half week cycle is worth roughly twice a client who drifts to five weeks and needs a near-full set each time at infill pricing.
That makes rebooking at the chair the highest-value habit in the studio, and the lapsed-client prompt the second. Both should be automatic: the next appointment offered before the client leaves, and a WhatsApp nudge at the point their own cycle says they are due — not a blanket monthly newsletter.
Full set, infill and removal as separate services with their own durations.
Per-client infill interval tracked, with a rebooking prompt at checkout.
Patch test and allergy history recorded and surfaced before treatment.
Per-artist commission, including different rates for sets and infills.
Photo records of each set so a different artist can match the style.
Patch tests are a record-keeping obligation
Adhesive reactions are the main clinical risk in lash work, and the defence is a recorded patch test with a date attached. Kept on a form in a drawer, it is unfindable at the moment it matters; kept on the client record, it is checked in the two seconds before the appointment starts.
The same record should carry known sensitivities and any previous reaction. This is not bureaucracy for its own sake — it is the difference between a documented process and a conversation about what someone remembers.

The bottom line
Build the studio around the infill cycle: separate services, per-client intervals, rebooking at the chair and an automatic nudge when someone is due. LABÉAU does that alongside per-artist commission, patch-test records and local e-invoicing from RM174.92/month.

Most lash clients need an infill every two to three weeks, depending on natural shed rate and aftercare. Past about four weeks the appointment becomes closer to a partial full set in both time and materials, which is why studios that price every infill identically end up subsidising the least frequent clients at the expense of the most loyal ones.
Many do, and the economics support it — the artist's time genuinely scales with how much has shed. Tiering infill prices by elapsed weeks (for example under two weeks, two to three, over three) is transparent, defensible to clients, and rewards the booking discipline you want to encourage.
Yes. Adhesive reaction is the main clinical risk in lash work and a dated patch test on the client record is the practical defence. Kept on the record it is checked in seconds before treatment; kept on a paper form it is unfindable at the moment it matters. LABÉAU stores patch test and allergy history on the client profile.
A solo artist with no staff, no packages and no e-invoice obligation may be well served by a low-cost calendar tool. Once you employ or contract other artists on commission, sell prepaid sets, or come into LHDN or IRAS scope, you need commission rules and compliant invoicing — which is where LABÉAU from RM174.92/month or TunaiPro from around RM69 become the practical options in Malaysia.
