11 Feb How to Choose the Right Nail Service: Gel Polish, BIAB, or Extensions?

Gel Polish, Builder Gel, or Acrylic Extensions — Which Is Right for You

When I first started doing nails, gel polish didn’t even exist. Most manicures ended with me carefully helping clients put their coats on or fixing smudges after they’d touched something too soon. Then gel polish arrived, and it changed everything. Instantly dry, glossy, and long lasting, it completely transformed how we worked.

Over the years, very few innovations have had the same impact, but builder gels have come close. They’ve bridged the gap between natural nails and traditional extensions, creating something strong, flexible, and much kinder to the natural nail.

I have always loved having beautiful nails, but mine are naturally weak. They never held extensions well, and gel polish would peel off within days. Builder in a Bottle, often known as BIAB, changed that for me. It gave strength, structure, and flexibility without feeling thick or heavy.

In our Durham salon, BIAB has become one of our most requested treatments. It has helped so many clients grow their natural nails and find a system that truly lasts.

What’s the Difference Between Gel Polish, Builder Gel, and Acrylic Extensions

Gel Polish

Gel polish is the lightweight option. It is applied like normal polish but cured under a lamp to create a flexible, chip resistant layer that lasts around two to three weeks. It is perfect for people with strong natural nails who want a thin, glossy finish that stays perfect for longer than traditional polish.

However, gel polish alone does not strengthen weak nails. It simply coats the surface. If your nails tend to bend, peel, or break easily, you may benefit from something with more structure underneath.

Builder Gel and BIAB

Builder gels are thicker, more durable versions of gel polish. They are made to reinforce natural nails or add gentle structure. When cured under a UV or LED lamp, they form a strong yet flexible layer that protects your nails without the heaviness of acrylic.

BIAB, short for Builder in a Bottle, is one of the best known versions of this system. It behaves slightly differently from older gels because it flexes with your nail rather than lifting or cracking. It can even be infilled rather than soaked off every time, which keeps your nails healthier in the long term.

If your goal is to grow your own nails while keeping them neat and strong, BIAB is the perfect middle ground. It provides protection, strength, and a flawless high gloss finish that lasts weeks.

Acrylic Extensions

Acrylic is the most traditional nail enhancement system and still one of the strongest. It involves mixing a liquid monomer with a polymer powder to create a paste that hardens as it is exposed to air. The result is a solid structure that can be shaped, sculpted, and filed into longer lengths.

Acrylics are ideal for those who want dramatic extensions or more sculpted nail designs. However, they are also more rigid and less flexible than builder gels, which means they can feel heavier and require more careful maintenance.

How They Compare

Builder gel and BIAB sit comfortably between gel polish and acrylics. They are more flexible than acrylic, stronger than gel polish, and kinder to your natural nails.

In our Durham salon, we find most clients prefer BIAB because it lasts longer, allows natural nails to grow, and feels light and comfortable. Acrylics still have their place for clients who want long or sculpted designs, but builder systems have become the go to for long term nail health and strength.

How to Keep Your Nails Looking Perfect

Whatever system you choose, good aftercare is key. Use cuticle oil every day to keep your nails hydrated and flexible. Wear gloves when cleaning or washing up, and avoid picking at lifted edges. Regular maintenance every two to three weeks keeps your nails strong and balanced.

If you have ever had problems with peeling, lifting, or breakage, we can help you find the right solution. Every nail type is different, and the right product makes all the difference to how long your nails last.

Which Option Is Best for You

Nail technology has come a long way from the days of basic polish and smudged finishes. Whether you choose gel polish, builder gel, or acrylic extensions, the secret is choosing the right system for your nail type and lifestyle.

For most of our clients in Durham, builder gels like BIAB have become the perfect balance between strength, flexibility, and a beautiful, natural looking result that lasts.
