Frequently Asked Questions

Everything you need to know

We're here to answer your questions about our services, booking process, and what to expect.

Our BIAB and hard gel overlays typically last 3-4 weeks with proper care. The longevity depends on your natural nail growth and daily activities. We recommend booking infills every 3-4 weeks to maintain the strength and appearance of your nails.

BIAB (Builder in a Bottle) is a flexible, soak-off gel that strengthens natural nails while maintaining flexibility. Hard gel is a more rigid overlay that provides maximum durability and is ideal for extensions or clients who need extra strength. Both are excellent choices—we'll recommend the best option during your consultation.

Yes, we offer sculpted hard gel extensions with single-colour luxe finishes. Extensions are perfect for clients wanting length or rebuilding damaged nails. Our extensions are meticulously shaped and finished to look natural and elegant.

You can book directly through Booksy by clicking any 'Book Now' button on our site. Choose your service, preferred artist (Ruth, Kate, or Yulia), and your preferred date and time. We're currently taking new clients and have availability throughout the week.

Your first visit includes a consultation where we discuss your nail goals, assess your natural nails, and recommend the best treatment. We'll guide you through our luxury experience, from the initial prep to the final high-gloss finish. Expect to feel relaxed, pampered, and leave with nails you'll love.

We maintain hospital-grade sanitation standards. All tools are sterilised, and we use single-use files for every client. Our workstations are immaculately cleaned between appointments, and we follow strict hygiene protocols to ensure your safety and comfort.
