Let's get into it.👇
Which formula by The Gel Bottle Inc is right for your clients? 💅

All In One BIAB
Perfect for short to mid-length natural nails

If you love speed, simplicity and a clean natural finish, All In One BIAB is your go-to. This formula is exactly what it says on the tin base, builder and colour in one. That means fewer bottles, fewer steps and quicker appointments, without compromising on strength.
Best for:
-
Short to mid-length natural nails
-
Clients who want a natural, polished look
-
BIAB infills and maintenance appointments
-
Faster services with minimal prep
It’s ideal for salons that want efficiency without sacrificing quality — especially if you’re fully booked and need your system working just as hard as you are.
Original BIAB
The iconic builder for strength and structure

This is the BIAB that started it all and for many techs, it’s still the backbone of their services.
Original BIAB offers more structure and control, making it perfect for clients who need added strength or a more defined apex. It’s a dream for techs who love sculpting and want a product that supports strong, healthy natural nails.
Best for:
-
Clients with weak or bendy nails
-
Creating structure and apex
-
Medium lengths
-
Long-term nail health and retention
If your clients are hard on their hands or regularly struggle with breakage, Original BIAB gives you that extra reassurance.
Hard BIAB
Extra strength for longer lengths

When your clients want length and durability, Hard BIAB steps in.
This formula is designed for those who love longer nails but still want a BIAB service rather than traditional extensions. It delivers extra strength while maintaining that smooth, professional finish The Gel Bottle Inc is known for.
Best for:
-
Longer natural nails
-
Clients prone to breakage
-
Stronger overlays with added durability
-
Advanced BIAB services
Hard BIAB is perfect if you’ve ever thought, “I love BIAB, but I need something stronger for this client.”
ProForm
HEMA-free hybrid for extensions

ProForm is where flexibility meets performance.
This HEMA-free hybrid system is ideal for techs offering extensions, refills and more advanced enhancements without compromising comfort for sensitive clients.

-
Nail extensions and infills
-
Clients with sensitivities

Sculpted shapes and longer lengths
If you want one system that bridges the gap between BIAB and extension work, ProForm deserves a place on your desk.
So… which formula is right for you?
The truth is, most salons don’t just use one.
Many techs mix and match formulas depending on the client, the service and the result they want to achieve. Short and natural? All In One. Need structure? Original. Going longer? Hard BIAB. Building extensions or catering to sensitivities? ProForm.
Once you understand the strengths of each formula, you’re no longer trying to make one product do everything you’re choosing the right tool for the job.
And that’s when your results (and your rebooks) really level up.
