Colour-integrated BIAB kapping (€60 / 60 min) combines strengthening overlay and colour in a single pigmented product. Faster and thinner than classic BIAB + semi-permanent on top (€70 / 75 min). 4-week wear. Smaller palette — pick this service if you want a long-wear solid colour.
BIAB ("Builder In A Bottle") has become Parisian women's favourite overlay: strengthening, smoothing, natural-looking. At You Rêve Paris, we offer two formats. The "colour-integrated" version is less known but can be the right pick depending on your need.

Colour-integrated BIAB: what is it?
It is a pigmented BIAB gel. The colour is already in the product at application time — no need to add a semi-permanent layer on top. Concretely:
- 1 product, 1 or 2 layers depending on opacity.
- 1 final LED cure.
- Top coat for shine.
Result: you save 15 minutes and skip an extra layer — therefore thinner on the nail.
Classic BIAB + semi-permanent: what is it?
The BIAB kapping + semi-permanent at €70 / 75 min splits the two steps:
- Clear BIAB layer strengthening and smoothing the nail.
- OPI semi-permanent layer on top, in the chosen shade.
- Final top coat.
Advantage: full OPI palette (~200 shades). Nail art on top is possible too.

When to pick colour-integrated?
- You want a solid colour — rosy nude, beige, pale pink, white.
- You prefer the thinnest possible finish on the nail.
- You want to save 15 min (and €10).
- No nail art planned on top.

When to pick classic BIAB + semi-permanent?
- You want a specific OPI shade (Big Apple Red, Lincoln Park, etc.).
- You want nail art on top (chrome, fine line, ombré).
- You want the most saturated colour possible.
What about the clear overlay alone?
For reference, clear overlay alone (transparent gel reinforcement, no colour) is at €50 / 50 min. It is the "winter maintenance" pick for those who want to strengthen the natural nail without any colour application. Very clean, very natural.
💡 Tip: Overlay removal is at €20 / 20 min. Factor it into your routine if you change salons or take a break.
How often to replace?
BIAB kapping lasts 4 weeks. At each follow-up, two options:
- Full removal + new application — recommended every 2-3 cycles.
- Infill + semi-permanent at €60 / 60 min — regrowth is buffed, filed, regelled.
