Yes, natural keratin is beneficial for hair, skin, and nails. Your body naturally produces keratin, a protein that strengthens and supports these structures. However, the "goodness" of keratin depends on the context. Natural keratin, as a component of your body, is essential for healthy hair, skin, and nails. Conversely, keratin treatments, while using keratin, can have varying effects depending on the product and application.
Benefits of Natural Keratin:
