Unlike most nail strengtheners that rely on marketing claims, Dr Tom Nailcare is backed by science. Using what we believe to be a world-first lab testing method, independent lab tests performed by Lincoln Agritech showed test nails were 30% stronger in 10 days (cream) and 78% stronger in 2 weeks (cream + liquid)

There are average results, not maximum claims, giving you honest expectations of what a nail strengthener can really deliver.

Dr Tom Cawood is a hospital consultant physician and published lab scientist with over 40 peer-reviewed papers. As a lifelong classical guitarist, he experienced years of weak, breakable nails that stopped him from playing guitar. Frustrated with nail strengtheners that didn't work, he used his medical and research background to create a solution that really delivers results. Today, his formula is trusted by musicians, nurses, hairdressers, and anyone who wants stronger natural nails without polish or artificial coatings.

Our nail strengthener is made with hydrolysed wool keratin that absorbs into the nail, not just coating the surface like most competitors. We use carefully chosen, biodegradable ingredients including NZ wool keratin, with no solvents, toxins, or artificial coatings. This keeps nails strong, flexible, and healthy naturally — without needing polish, gel, or varnish. The absorption difference means your nails strengthen from within, delivering lasting results that don't wash off or chip away like surface coatings.

This nail treatment delivers hydrolysed wool keratin into the nail, where it binds to the nail's keratin fibres, reinforcing it from within and helping it stay strong and flexible, not just coating the surface with temporary hardeners. Every ingredient targets a specific repair need — wool keratin helps strengthen the nail, moisturisers help keep it flexible, protective compounds prevent further deterioration. Zero harsh solvents that cause more damage. Zero toxins. Zero artificial polymers that create brittle layers over weak nails. The treatment penetrates to where damage exists, strengthening from within your nail's own structure. The effects happens at the foundational level because the keratin absorbs into the nail; results don’t chip or peel off like coatings.

This nail repair kit combines two treatments in one comprehensive system for maximum repair results. Using what we believe is a world-first lab testing method developed from New Zealand sheep's wool keratin, independent testing showed test nails were 78% stronger in 2 weeks with cream plus liquid. Used separately, the cream alone made lab nails 30% stronger in 10 days. We report average outcomes, not maximum claims, so you can better appreciate what this comprehensive kit can achieve for severely damaged nails. This complete system approach delivers results that individual products cannot match when used together.
