How It Works

From NZ wool to stronger nails.
Science-backed nail care that strengthens from within.

Most nail products coat the nail.

Ours strengthens it from within.

Dr Tom contains a specialised form of keratin, derived from New Zealand wool.

This keratin absorbs into the fingernail and binds to the nail's keratin fibres, reinforcing it from within.

This makes your nails stronger, more flexible and helps prevent breaking or peeling.

In lab testing, the formula increased nail strength by 30% in 10 days. Real users reported nails that were smoother, stronger, and visibly healthier.

Most products coat the nail,
ours goes deeper


  • Absorbs into the nail rather than sitting on top

  • No solvents, no polish, no removers needed

  • Two formulas that work beautifully on their own - and even better together.
    The intensive liquid and strengthening cream both help strengthen your nails. Used together, they combine targeted strengthening with deep hydration and care.

  • Use as often as you like - we recommend at least once a day

Behind The Science
The Nail Struggle: What I Tried Before

Before developing my own formula, I tried everything – nourishing oils, nail varnish-based hardeners, acrylics, even glued-on fakes.

  • Oils helped a little, but didn’t prevent breakage.
  • Varnish-based products flaked off and took layers of nail with them.
  • Nail polish removers only made things worse.
  • Acrylics helped short-term but damaged my nails long-term.

Each attempt left my nails weaker and me even more frustrated.
Creating a Way to Test Nail Strength

There was no reliable lab method to test nail-strengthening products. So we made one.

With support from a local university and Callaghan Innovation, we:

  • Developed keratin-based test nails (from NZ sheep’s wool).
  • Standardised their size and thickness.
  • Used tensile testing machines to measure flexibility and breakage strength.

This method gave us measurable, scientific data – a game-changer for product development.
How 30/95 Works

40 people tested the product:

  • 95% of guitarists said it was effective or very effective.
  • 93% of all testers (including a nurse, teacher, and hairdresser) had positive results.
  • One guitarist needed longer to see results, but it worked in the end.

Why It’s Called 30/95

Simple, 30% stronger nails in the lab. 95% of guitarists found it effective.

That balance of science and real-world results is what sets it apart.
