BIAB has become one of the most popular nail treatments in Australia, and it is easy to see why: it looks natural, lasts for weeks and feels strong. But many people who decide to take a break from it find that the nails underneath have become thin, bendy and prone to peeling and breaking. If that sounds familiar, this guide explains why it happens and what actually helps, from a doctor who has spent years working on exactly this problem.
What BIAB is, and why it feels so good
BIAB stands for "Builder In A Bottle", a builder gel originally made by The GelBottle Inc. The name is now often used for builder gels in general. It is applied like a gel polish but in a thicker layer, then hardened under a UV or LED lamp. The result is a strong, flexible coating that protects the nail while it is on, which is why many people find their nails seem to "grow" better with it.
The catch is that the strength belongs to the coating, not to your nail. Underneath, the nail plate is not being strengthened, and it can be weakened by how the coating is applied and removed.
Why your nails feel weak after BIAB
There are three common reasons, and most people have a mix of them:
- Filing and buffing. Each application usually starts with buffing the nail surface so the gel grips, and removal often involves filing or an electric file. Over months, that can take off layers of the nail plate, leaving it thinner and more bendy.
- Removal. Even the maker of BIAB warns that incorrect removal can cause peeling or thinning, and that you should never force or pick off product that hasn't fully lifted. Peeling it off yourself takes the top layers of nail with it.
- Dehydration. Acetone used for soak-off removal has the effect of striping out water and natural oils from the nail, which makes it more brittle for a while.
The good news is that in most people this is damage to the nail plate, not to the nail's "root" (the matrix), so it is recoverable if given enough time for new nail to grow.
How to come off BIAB with the least damage
- Have it removed professionally if you can, and ask for a gentle soak-off or for the technician to leave a thin layer rather than filing down to the nail.
- Never pick or peel it off. It is tempting, but it is the single most damaging thing you can do.
- Don't rush. If it hasn't softened, it needs longer, not more force.
- Rehydrate straight away. Afterwards, your nails will be at their driest and most fragile.
Your recovery plan
Keep them short for now
Thin nails are more likely to bend and tear when they are long. Filing them short and slightly rounded, with a glass file rather than clippers, reduces snags while they recover.
Protect them from water and detergents
Repeated wetting and drying makes nails swell and shrink, which loosens their layers. Wear gloves for washing up and cleaning, and dry your hands well.
Strengthen the nail you have
This is where a treatment that works on the nail itself, rather than coating it, helps. Dr Tom's cream and intensive care liquid use hydrolysed keratin from sheep's wool, small enough to absorb into the nail plate and create new keratin bonds between the keratin fibres in your nail, to strengthen the nail structure from within. In independent lab tests by Lincoln Agritech, test nails treated with the combination were 78% stronger after two weeks. It works on the nail you already have, so it can start working the day your BIAB comes off.

Be patient with the rest
Fingernails grow roughly 3 mm a month, so the nail that was under BIAB is gradually replaced over several months. Strengthening the existing nail makes that period much easier, helping provide sufficient strength to the damage section of the nail, whilst the fresh new nail gradually replaces it as it grows out.
Can you go back to BIAB later?
Yes, if you want to. Many people use BIAB on and off. If you do, ask for gentle preparation and removal, take regular breaks, and keep strengthening your natural nails in between, so each round starts from a stronger base.
If you develop itching, redness or swelling around the nails after gel or BIAB treatments, stop and see your GP. It can be a sign of an allergy to ingredients in the gel, which is worth knowing about before your next appointment.
Frequently asked questions
How long does it take for nails to recover after BIAB?
Your nails can feel stronger within days to weeks with the right care. Fully replacing the nail that was under the BIAB takes several months, because that is how long a nail takes to grow out.
Is BIAB better or worse for nails than acrylics?
BIAB is generally gentler than acrylics, but the damage people notice comes mostly from preparation and removal, which can happen with either.
Should I take a break from BIAB?
If your nails are thin, peeling or sore, a break of a few months gives them a chance to recover.
Can I use Dr Tom while I still have BIAB on?
No, the Dr Tom products absorb into the natural nail and so need to be applied to bare nails to get the strengthening benefit. They are ideal for strengthening and rehabilitating the natural nails between periods of having an artificial coating on the nails (like polish, BIAB or acrylics).
Do you deliver in Australia?
Yes. Australian orders are dispatched from Sydney, and prices are in Australian dollars.
The bottom line
BIAB protects your nails while it is on, but preparation and removal can leave the nail underneath thin and weak. Remove it gently, keep your nails short and dry, and strengthen the nail you have while the new one grows. The Dr Tom Nail Strength Combo is designed for exactly this, and comes with our money-back promise if you don't see a benefit after consistent use.
