What is the difference between BColour and Gellak?
Both systems share the same professional-grade performance, so where does the real difference lie? Let's start with what they have in common before breaking down what sets them apart.

BColour: the fastest 1-layer colour gel in a bottle
If you're searching for a time-saving colour gel, BColour is designed for you. It's an ultra-opaque colour gel in a bottle that delivers full coverage in just one layer. No extra steps, no wasted time.
Business advantage of BColour
Less application time = more appointments per day = higher turnover, without working longer hours. If you're running a tight schedule, BColour directly impacts your salon's profitability.
Gellak: classic colour gel in a jar for maximum precision
Prefer working with a separate brush? Love applying two thin layers? Gellak gives you the traditional jar experience with maximum precision. Ideal for nail art and clients who want a fully customised result.
Gellak is perfect if you frequently perform nail art, prefer gradual layering, want maximum control over product pick-up, or are accustomed to classic jar systems. It offers precision and familiarity without compromising on performance.
Business advantage of Gellak
Maximum brush control and gradual layering give you the precision to deliver flawless, custom results. For salons that build their reputation on detail, nail art and a personalised client experience, Gellak is the natural choice.
Bottle vs jar: which colour gel is faster?
A 1-layer bottle system is faster, and the reason is straightforward.
BColour requires only one application layer, one curing cycle, and has no sticky layer to remove. This can significantly reduce total service time per client. However, speed is not always the deciding factor. Some professionals prefer the control and technique of a separate brush, and that is exactly where Gellak excels.
Which colour gel is more profitable for a salon?
Profitability depends on your salon model, your average service time and the type of appointments you fill your day with. And that's exactly where the choice between BColour and Gellak becomes clear.
Choose BColour if...
→ You want higher daily client turnover
→ You prioritize time efficiency
→ You focus on speed-based services
→ You work with tight appointment schedules
Choose Gellak if...
→ Your salon focuses on custom finishes
→ You perform detailed nail art
→ Your workflow is brush-based
→ You value control over product application
Both systems deliver the same high-end professional result that ProNails is known for. The difference lies not in the finish or the quality, but in how you get there and the workflow that suits your salon best.
