Toothpaste from Hair

The primary focus of the discussion centers on the effectiveness of a new toothpaste made from hair, which "mimics the structure and function of natural enamel." Users express skepticism about its true repair capabilities versus merely providing a protective layer, comparing it to existing products like novamin.

Another recurring theme in the discussion is the comparison with other innovative dental treatments. One user questions, "How does this compare with nano-hydroxyapatite?" suggesting that while the hair-based toothpaste is intriguing, existing solutions may offer more established benefits.
