Builder in a bottle, overlays, infills

BIAB and builder gel

Builder gel overlays that strengthen your natural nails so they grow instead of snapping, infilled every three to four weeks rather than removed, in sheer nudes or any colour on top.

BIAB is the treatment for people whose nails break at the corner every time they get past the fingertip. It is a thin, flexible layer of strength, and it is most of what we do.

Builder in a bottle is a thicker gel applied in a thin layer over your natural nail with an apex (a slight dome in the middle) that gives it strength where it bends. Your nail grows underneath, protected, and every three to four weeks we file the overlay back, fill the regrowth and reshape, rather than taking it all off. Over a few months most people end up with the long natural nails they had given up on.

It comes in sheer pinks, nudes and milky whites that look like very good natural nails, or with a gel colour or nail art on top. We also do a short-nail BIAB for people who want strength without length.
