Revolution in Dentistry: Toothpaste Made from Human Hair to Restore Enamel Invented
British scientists have developed an innovative product capable of regenerating damaged teeth
A breakthrough in dentistry has been made at King's College London that could change the way we look after our teeth forever. Scientists have discovered that keratin, a protein found in human hair, can form a protective coating identical to natural tooth enamel.

The discovery promises to revolutionise the treatment of dental caries and tooth sensitivity, offering a fundamentally new solution where traditional dentistry has failed.
“Unlike bone, tooth enamel does not naturally regenerate,” explains researcher Sherif Elsharkawy. “But keratin coating could be the first truly effective regeneration method.” When exposed to minerals in saliva, keratin forms a crystalline structure that not only protects the tooth, but also continues to attract calcium ions, gradually repairing damaged areas.
The technology is environmentally friendly — the raw materials are biological waste (hair and skin), and the production itself excludes the use of toxic resins used in modern dentistry. As researcher Sarah Gamea notes, "keratin coatings look more natural than traditional fillings, precisely matching the color of the teeth."
In the next 2-3 years, the innovation may appear in the form of a toothpaste for home use or a professional gel for clinical use. This opens up new prospects for millions of people suffering from increased tooth sensitivity and caries, offering a solution that works in harmony with the body's nature, rather than simply masking the problems.
“We are at the threshold of a new era in dentistry,” concludes Dr. Elsharkawy. “Soon, a simple haircut may become the source of material to restore your smile.”
