Lock in smoother, longer-lasting wear from your favourite nail colour while also noticeably strengthening nails, boosting condition and protecting from breakage. All it takes is a sweep of our dual-action base coat and strengthening nail treatment.

Oxygenated, 12-free and vegan-friendly, our nail care icon harnesses Hexanal - a patented active that’s proven* to reduce nail fragility, brittleness and splitting:

  • 90% felt nails were stronger & healthier 
  • 90% felt nails were repaired & regenerated 
  • 85% felt nails were harder 

Wear alone or underneath Nailberry polish and say hello to a healthier manicure!

*Results based on user trials. 20 participants applied Hexanal 2x weekly for 3 weeks.

Directions for use

Apply one thin coat for a breathable base coat or two coats twice weekly as an intense repair treatment. Our wide, tapered brush ensures your nail is flawlessly coated from base to tip in this fortified formula.

Superb Base Coat!

This goes on smoothly and I am confident that my nails are being looked after with the quality ingredients. My manicure lasted really well and it is great that it can be used to benefit your nails whether or not you add colour.

No more yellow nails!!

No more spending the winter growing out yellowed toenails. A joy to have the choice of wearing or not wearing varnish during ’sanda’l season as toenails remain a healthy and white colour between applications.

Looks like tipex and melts in the heat, most mornings my toes were stuck to my duvet and that created a bumpy texture
As it’s the only varnish I took away with me I ended up having to redo it every morning
Also not breathable- still had issue with nail infection
£19 for a nail varnish and it didn’t do what it said on the tin - will stick to my £3. 99 from boots
