Is BIAB Good for Your Nails?

Builder in a Bottle, BIAB, isn’t new. But it’s having a moment. Once a niche salon service, BIAB is now a staple for nail techs and beauty lovers who want durability without bulk. If you walk past any nail bar, you’ll often see a sign advertising that they offer BIAB as a service. The question many clients will want to know, though, is simple: Is it good for your nails?

The short answer: when applied and removed correctly, BIAB can protect your natural nails and even help them grow.

But let’s unpack that properly.

What is BIAB?

BIAB is a type of soak-off builder gel developed to strengthen natural nails. It sits somewhere between gel polish and hard gel. Unlike acrylic, which requires separate primers and powders, BIAB is a self-levelling product applied directly from the bottle and cured under a lamp.

Think of it as a tough but flexible base that allows natural nails to grow underneath.

“The real strength of BIAB lies in how it supports the natural nail without overwhelming it. When used properly, it can give clients weeks of chip-free wear—and help reduce breakage,” says Charli Jepson, Head of Education at Glitterbels.

The Pros - why BIAB has become so popular

1. Strength and flexibility

BIAB is designed to bend slightly with the nail rather than snap. That makes it more forgiving than traditional acrylic, particularly for clients who are hard on their hands. Caveat: clients should realise that BIAB nails are not indestructible and, as with any manicure, care should be taken to protect both the design and the natural nail. 

2. Promotes nail growth

The protective layer gives natural nails the chance to grow undisturbed. Regular BIAB users often find their nails are longer and stronger over time.

3. Softer removal process

Because it’s a soak-off gel, there’s no need for aggressive filing to remove it, so long as you know what you’re doing (why not check out our range of online Builder Gel course here). 

4. Minimal lifting

When applied well, BIAB bonds to the nail plate securely. That reduces lifting and helps avoid moisture getting trapped (which can lead to bacterial issues).

Where BIAB can go wrong 

Like any nail system, BIAB isn’t miracle-proof. The health of the natural nail depends heavily on the skill of the technician and the quality of aftercare.

1. Over-filing is a risk

Poor prep work or overzealous removal can thin the natural nail plate. That’s not a BIAB issue, that’s an education issue. 

2. Incorrect removal causes damage

Peeling or picking off BIAB can strip away layers of the natural nail. Clients need education here. Soak-off or professional removal is a non-negotiable - DIY’ing removal of any manicure is not recommended. 

3. Not always breathable

Some clients worry about nails “breathing”. Nails don’t need to breathe, but if you’ve had damage or trauma, taking breaks between applications may help.

“Any system can damage nails if misused. What we see with BIAB is that in the right hands, it’s one of the safest options for clients wanting both strength and style,” says Jepson. “Our HEMA-Free Builder Gel is a smart choice for clients who are allergy sensitive”. 

How BIAB Compares to Acrylic and Gel

Who Should Try BIAB?

• New clients who want to move away from acrylic.
• Busy professionals need longevity without maintenance.
• Nail biters or those with weak nails—BIAB can act as a tough rehab programme for poor nail health.
• Minimalists who prefer a clean, natural look.
• BIAB can be used alone for a sheer, natural finish, or as a base under gel colour or art. It adapts to your style and your lifestyle.

How to Keep BIAB Nails Healthy

• Don’t pick. Ever.

Peeling ruins the nail plate. If lifting occurs, get it repaired professionally.

• Use cuticle oil.

Daily application keeps nails and skin hydrated, preventing brittleness.

• Book infills, not removals.

BIAB is designed to be filled and rebalanced, not removed every time.

• Stick to 2–3 week appointments.

Overgrown nails risk lifting and snapping.

• Choose trained professionals.

Clients should only be booking BIAB treatments with trained professionals, just like you. 

Final Verdict: Is BIAB Good for Your Nails?

Yes, if applied and maintained correctly. BIAB doesn’t damage the natural nail; poor technique does. When used by a qualified nail tech with proper aftercare, BIAB is arguably one of the best options for strength, flexibility, and nail health.

For clients looking to move away from harsh systems or give their nails a protective boost, though here at Glitterbels HQ are slightly biased, it’s a strong “yes” from us.

Not when applied and removed properly. It’s often used to improve nail health by reducing breakage and encouraging growth.
