What is keratin exactly?

As we mentioned above, keratin is a protein naturally found in our bodies. More specifically, it’s a family of structural proteins that makes up a lot of different parts of our bodies. From the outer layer of skin to our hair and our nails, keratin plays a key role in your body’s makeup. Keratin is present in both the outer protective layer of each hair shaft and the inner cortex, too.

Damaged hair has often suffered losses in the keratin department. Hair dye processes and exposure to heat can compromise the structure of each hair shaft. You’ll notice visible differences in hair that’s been damaged and is lacking those proteins. Along with switching up your diet, there are certain products you can incorporate to help strengthen your strands and restore some of that protein.
