What is the difference between BIAB and gel polish?

Gel polish is a thin coloured layer. BIAB is a thicker builder gel that adds strength to the nail itself, and it can be worn clear, nude or with colour on top.

BIAB or gel extensions: which should I choose?

Choose BIAB if you want to grow and protect your own nails. Choose gel extensions if you want extra length or a set shape straight away.

How long does BIAB last?

Around three weeks. After that we infill the regrowth, so you do not need a full removal every time.

Does removing BIAB or gel damage nails?

Not when it is removed properly. Peeling it off is what thins the nail. Removal in the salon is quick, and it is free when your set was done with us.

Is BIAB good for weak nails?

Yes. It adds a strong layer over the natural nail, so weak nails can grow longer without splitting.

BIAB, short for Builder In A Bottle, is a thicker gel that is brushed over your own nails. It gives them strength, so soft or bendy nails can grow without snapping. Gel extensions are for when you want more length or a different shape than your natural nails can give you.

Both last around three weeks before an infill or a fresh set. If you are not sure which one you need, tell us how your nails are now and what you would like them to look like, and we will suggest the right option before we start.

What BIAB Does For Your Nails

BIAB is a builder gel, thicker than normal gel polish, brushed over your own nails and cured under a lamp. It gives weak, soft or bendy nails a strong layer so they can grow without breaking. It can be left clear or nude for a natural look, or finished with colour.

Because it is infilled as your nails grow, you do not need to remove it completely every few weeks, which is better for your natural nail.

Gel Nail Extensions

Gel extensions add length and shape your natural nails cannot give you yet. We sculpt the extension to the shape you want, such as almond, square or oval, then finish with colour or nail art. Bring a photo of the length and shape you like.

Gel Manicures

If you are happy with your natural length and just want colour that lasts, a classic gel manicure is £28 and a deluxe gel manicure, with scrub and paraffin wax, is £32.

Aftercare

Use cuticle oil every day, wear gloves for washing up and cleaning, and do not pick or peel your nails. Book removal or an infill at around three weeks. Removal is free if your set was done with us.
