Techniques

Fill

Rebuilding the grown-out gap at the base of an enhancement, leaving the rest in place.

Every two to four weeks the nail grows and a bare strip appears at the cuticle. A fill files back the old product, adds new product into the gap, and rebalances the shape — cheaper and quicker than taking the whole set off.

A full set is priced differently from a fill for this reason, and a set left too long usually needs the former.

Also called: infill, backfill, touch up
