Lash infills
explained.

In plain English

A lash infill is a maintenance appointment that refreshes a suitable existing extension set as the natural lashes grow and shed.

What the term means.

An infill involves more than putting extensions in visible gaps. Existing attachments are assessed, and unsuitable or excessively grown-out extensions may need professional removal before suitable lashes are refreshed.

The appropriate booking depends on the remaining coverage, time since the previous visit and style already applied. A short maintenance slot cannot necessarily rebuild a very sparse set. Share details of a change of artist or style before selecting an appointment.

Maintenance time versus a new full set

These are industry definitions. Product names, profiles and availability vary; your artist selects the actual system and construction for your appointment.

A common question.

Is the infill interval the same as retention?

Retention describes attachment performance. Maintenance also reflects natural growth and how full you want the set to appear, alongside the studio's booking rules.
