Everything You Need to Know About Keratin
Keratin is a fibrous substance that is found in the outer layers of the skin as well as the hair and nails. It is necessary for these to be strong and healthy, which is why many products today are fortified with keratin supplements.
The fibers of keratin bind together and make skin, hair and nails stronger and more radiant and resilient; it is a key component of the structure of hair and nails. When you have a lack of keratin in your system, your skin may seem sallow and dull, your hair may be weak and break easily, and nails may be brittle and split.
Keratin is a commonly used ingredient in hair straightening products, as pulling natural curl out of hair will put tension on the ends and the hair shaft. If the hair is not strong enough, those straightening treatments will cause it to break or split.
A keratin treatment may also be used for those with thin and brittle hair that splits at the ends; it will give hair an outer layer of protection from breakage.
Keratin is also often founds in nail treatments to make nails stronger and to avoid splitting and breaking. If your nails tend to split or chip, try a product with keratin to give them an added layer of strength and protection.
Many products that use keratin will be using a synthetic form of this protein; it may also be derived from certain forms of silk. These synthetic forms are safe and healthy and will help to give your hair and nails the strength they need to grow long and strong.
