If you’ve ever looked down at your nails and noticed one of them narrowing oddly at the tip, sometimes even feeling a little tight or uncomfortable, you’re not alone. A question that comes up frequently in salons and online forums is: “What is this strange shape happening to my nail?” More often than not, it’s something called a pinched nail, and it’s especially common after gel removal.
This seemingly small change can feel alarming, particularly if it’s a new development. The good news? It’s usually reversible once you understand the underlying causes — and that’s exactly what we’re unpacking today. Whether it appeared suddenly or was masked by a product like builder gel o BIAB, a pinched nail after gel removal is your nail’s way of telling you it needs a little extra care.
¿Qué es exactamente una uña pinzada?
Una uña pellizcada se refiere a placa para clavos that appears to taper unnaturally at the free edge, creating a tight, sometimes concave shape that hugs the fingertip more than usual. It can look like the nail is being squeezed from the sides, hence the term pinched. Some people describe it as a claw-like or “sucked in” appearance at the tip, while others notice discomfort or even slight pressure under the nail.
It’s not always a cause for panic, but it is a sign that your nails are trying to tell you something.
Por qué a menudo se ve una uña pellizcada después de la eliminación del gel
This might sound familiar: you soak off your gel, buff lightly, and suddenly notice your nail looks… different. Tighter. Narrower at the tip. That’s the pinched nail showing up, and it’s incredibly common right after removing gel polish or gel overlays.
Why? Because gel products, especially those with a rigid structure like builder gels or hard gels, bond closely with the nail.
Eliminarlos implica una mezcla de acetona and physical filing, two things that, when paired, can wreak havoc on the nail’s natural moisture and structure. Acetone shrinks and dehydrates the nail plate, while filing thins it, especially around the edges. This combo weakens the sidewalls, and without that support, the nail can start to collapse inward, mimicking the look of a pinched nail. Even if you’ve been super careful, small bits of overfiling across several appointments can add up. And the thinner the free edge becomes, the more prone it is to curling or “pinching” once the gel is gone and the nail is left unsupported.
This is why many people notice a pinched nail only after gel is removed — not because it appeared suddenly, but because the gel had been masking the shape change all along.
Cómo la contracción del gel y la respuesta del hiponiquio pueden alterar la forma de las uñas
Behind the free edge of the nail plate lies the hyponychium, one of the important guardian seals, what you may not be aware of is a lot of BIAB’s or Builder Gels shrink when they cure, how much they shrink depends on the ingredients, but know that they all do to some extent and if you have filed into the lateral nail folds and weakened the nail plate the structure of the nail is compromised and the nail plate will change shape. The other part of the problem is due to the pressure on the free edge the hyponychium will be irritated and part of its defense when its irritated is to call in the troops and thicken a little, causing more pressure on the underside of the free edge. How do we know this? During the Covid-19 pandemic a lot of our consumers removed their own nail product as this couldn’t be infilled, so 2 things happened:
- Llenaron demasiado en un esfuerzo por eliminar el producto
- They couldn’t get their nails redone and el hiponiquio tuvo tiempo de recuperarse.

Causas comunes de una uña pellizcada
Now that we’ve tackled the gel connection, let’s look at other factors that can trigger or worsen a pinched nail:
1. Exceso de perfil en las paredes laterales
Possibly the biggest offender. Over time, repeated filing — even gentle — can thin the sidewalls, especially when removing enhancements like Plexigel. Once those side areas lose structure, the nail’s free edge is left vulnerable and can start curling inwards as it grows.
2. Deshidratación por inmersión en acetona
Acetone, while great for product removal, pulls moisture from both the nail plate and surrounding skin. If you’ve ever felt that chalky, tight sensation post-soak, you know the feeling. Prolonged exposure, especially if followed by buffing, can temporarily (or permanently) warp the nail shape.
3. Anatomía natural o traumatismo repetitivo
Algunas personas son naturalmente más propensas a sufrir un pinzamiento de uñas debido a su lecho ungueal shape. But if it’s something you’ve only recently noticed, look at lifestyle habits. Typing, picking, tapping, or even frequent exposure to pressure under the free edge can distort growth over time.
4. Cambios en el hiponiquio
The hyponychium, the sensitive skin under the free edge, can shift or recede if irritated. This may happen due to overfiling, chemical exposure, gel shrinkage during curing or friction. When this skin detaches or becomes inflamed, the nail may grow in tighter, adding to that pinched look.
Cómo cuidar y prevenir una uña pellizcada
If you suspect you’re dealing with a pinched nail, don’t panic. It’s often reversible with a little care and patience.
1. 1. Tómate un descanso
Aléjate de las mejoras y da a tus uñas la oportunidad de recuperarse. Un mes sin geles ni quitaesmaltes permitirá que la lámina ungueal crezca con normalidad y recupere su forma natural.
2. Rehidratar, Rehidratar, Rehidratar
Nails need moisture just like skin. Apply a good quality nail & skin oil behind the free edge at least 4 times a day. Rinse your hands a few times a day with an Allantoïne & Ureum rinse, this will help recondition the nail and surrounding tissue, and finish with a little of your favorite lotion, if it contains Allantoïne and Ureum that’s an added bonus and your nails and nail area will love you for it.
3. Minimizar nuevos traumas
During this recovery period, Keep nails trimmed short to prevent catching or bending. Be gentle when typing, opening containers, or using your nails as tools (just don’t!).
4. Evite limar las zonas finas
Skip the sidewalls entirely when buffing or shaping for now. Focus only on gentle surface smoothing if needed — and avoid pressure.
5. Seguimiento de patrones
If it’s spreading to other nails or worsening, it could signal an underlying health or nutritional issue. Keep an eye out and consider speaking to a pro if you’re concerned.
Reflexiones finales
A pinched nail might start as a subtle cosmetic change, but it’s often a message from your body or your habits, that something needs adjusting. Whether it’s overfiling, dehydration, trauma, product shrinkage or just the aftermath of gel removal, paying attention early can help you course-correct and avoid long-term damage.
