What to expect

Week 1 to 2: Nails start to feel harder and less bendy as Miracle Base Coat builds strength. In our consumer trial, 90% of people experienced less breakage within this window.
Week 2 to 4: With weekly application, nails should feel more resilient and break less often. Daily Self Love Oil keeps them hydrated and flexible rather than brittle.
Ongoing: Real, lasting strength comes as healthier nail grows out and replaces older, weaker nail. Fingernails take 4 to 6 months to grow out fully, so this set works best as an ongoing routine, not a one-off fix.

If your nails feel brittle or their condition worsens at any point, stop use and get in touch.

FAQs

People with healthy nails that are naturally soft, bendy or prone to breakage, and who want to strengthen them over time.

Anyone with damaged, brittle, peeling or splitting nails should start with the Ultimate Nail Rescue Set first, and move to this set once nails are healthy again. It is also not suitable for nails with a fungal or bacterial concern, or for children, as solvent-based products are not recommended for them. Always read the ingredients, patch test first, and stop use if any reaction occurs. Speak to your GP or podiatrist if you have concerns.

They do different jobs. The Ultimate Nail Rescue repairs and rehydrates nails that are damaged, peeling or splitting, often after gels or salon wear. The Strong Nails Set hardens nails that are inherently soft or weak. In short: Rescue fixes what is damaged, Miracle makes what is weak stronger. If your nails are damaged, start with Rescue, then move to this set for ongoing strength.

Yes. Once your nails are healthy again, the Strong Nails Set is a natural next step to keep them hard and resilient and reduce future breakage.

No. Many traditional nail hardeners rely on formaldehyde, which can leave nails brittle. Miracle Base Coat uses plant-derived Hexinal instead, so it strengthens without the brittleness.

It should not. Hardeners that over-harden are usually formaldehyde-based. Hexinal strengthens while keeping nails flexible, and using Self Love Oil daily keeps them hydrated. If your nails ever start to feel brittle, stop use and get in touch.

In our 2-week consumer trial, 90% of people experienced less breakage in that time. You apply Miracle Base Coat once a week, so give it a few weeks of consistent use. Lasting strength builds as healthier nail grows out.

Use a non-acetone remover before each weekly reapplication.

Yes, it works on both fingernails and toenails.
