Lash Refill vs Full Set: Which to Book

· Updated · Iris

Whether to book a lash refill or a full set depends on how many days have passed and how much of your current set remains. Book a refill within 1–22 days with roughly 40% or more extensions left; book a full set if you are new, switching styles, or past 23+ days.

What does a lash refill include?

A refill replaces extensions that shed with your natural cycle and refreshes growth areas. The artist removes loose or twisted extensions, cleanses, and rebuilds density so the set looks freshly mapped again. Refills work best when you return on the studio schedule — 1–8, 9–15, or 16–22 days — while enough of the original set remains.

Iris Lash refill day windows

Pricing and eligibility follow days since your last full set or refill. Earlier fills cost less and keep lashes fuller.

  • •1 Week Ago — 1–8 days ($45–$60 depending on style)
  • •2 Weeks Ago — 9–15 days ($60–$95 depending on style)
  • •3 Weeks Ago — 16–22 days ($65–$110 depending on style)
  • •23+ days — new full set required

When is a full set the better choice?

Choose a full set if you are new to extensions, switching styles, coming from another salon with a mixed curl or map, or you have waited 23+ days so most lashes are gone.

  • •New client - full set
  • •Style change - full set
  • •About 40%+ extensions remaining within 1–22 days - refill
  • •Sparse / 23+ days - full set

Pricing and Scheduling Your Lash Appointment

Check the pricing menu for current refill and full-set rates by style and timing, and review the store policy refill schedule. If you are unsure which to book, message the studio a clear photo of your current set first.

Frequently Asked Questions

Most clients refill every 1–3 weeks using our windows: 1–8 days, 9–15 days, or 16–22 days. Returning on schedule makes each visit shorter and usually costs less than waiting for a full rebuild.

Yes. Changing styles — for example classic to volume — is best done with a full set so the mapping and curl are consistent rather than mixed.

If you are unsure, send the studio a clear, well-lit photo of your current lashes and they will recommend a refill or full set before you book.
