What Is Keratin?
Keratin- (noun) a fibrous protein forming the main structural constituent of hair, feathers, hoofs, claws, horns, etc.
Keratin is a strong protein that makes up our hair, nails, skin and teeth. Humans are not the only ones who produce keratin, most animals do as well. Due to the cysteine disulfide, keratin is almost non-dissolvable. Depending on the concentration of cysteine disulfide, the bond can create extremely hard cells such as hooves, teeth, and horns or the cells can become softer as in hair and skin. There are high levels of cysteine disulfide (a sulfur-containing amino acid) which give a distinct sulfurous odor when the keratin is burned.
Keratinocytes are living cells that make a large part of your skin, hair, nails etc. and this is what forms keratin. Every day you shed several thousands of keratin cells. The cells slowly push their way upward and will quickly die. These dead keratin cells form a protective layer around the healthy, new keratin cells. If the external layer of keratin becomes damaged, it could possibly result in unhealthy looking and flaky or cracked hair. Eating such foods as gelatin or regularly conditioning and moisturizing the hair can help to protect the outer layer of keratin.
All in all, the thicker the layer of keratin, the healthier the hair and/or nails are. Again, the outside dead cells are protecting the new living keratin cells at the core. By keeping the external layer of keratin moisturized it will prevent from splitting and/or cracking. This applies to your hair, skin and nails.
