A keratin It is one of the most important ingredients for hair. It is almost synonymous with healthy hair, as well as strengthening and protecting the hair fibre. We are talking about keratin, which is a fibrous and resistant protein already naturally present in our body. It is responsible for the composition of hair and nails. Many people may have already heard of it, but let’s dive deeper to find out exactly how it works and when it is recommended to improve hair health.

At these times it is worth using a wide-toothed comb to gently detangle wet locks, starting from the ends and gradually working upwards.
