What mineral is essential in hair care products to strengthen hair?

Keratin is a fundamental protein that forms the structure of hair, skin, and nails. It is critical in hair care products because it helps to strengthen the hair by filling in damaged areas and restoring the natural protective layer. When hair is processed, it can become weak and brittle, and the inclusion of keratin in products like shampoos, conditioners, and treatments works to rebuild the hair's integrity.

Additionally, keratin treatments can provide a smoothing effect, making the hair look shinier and healthier. By replenishing the keratin in the hair, these products can improve manageability and resilience, ultimately leading to stronger hair. While other minerals and nutrients can contribute to overall health, keratin directly addresses the structural components necessary for hair strength and wellbeing.
