Learn the ins and outs of this naturally-occuring protein.

Over the past few years, keratin has been one of the buzziest ingredients in the hair industry. You may even be wondering, “What is keratin?” 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 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. When hair losses too much of this protein, it becomes damaged. Along with switching up your diet, there are certain products you can incorporate to help strengthen your strands and restore some of that protein. Keep scrolling to learn more about this protein and find out what products to use to achieve the benefits.

Like we mentioned above, damaged hair is often the result of a loss of keratin. Hair dye processes and exposure to heat compromises the structure of your hair shaft. They’re two of the most common ways keratin in lost. You’ll notice visible differences in hair that’s been damaged and is lacking proteins versus healthy strands.

First things first: Do no harm. If you’re planning on continuing your heat-styling ways, you’ll want to start prepping your strands with a heat protectant. We love using TRESemmé Keratin Smooth Heat Defense Spray. This helps add shine and softness while shielding your hair from the damaging effects that hot tools can have on your strands. Plus, the protein and African Marula oil help fight frizz and any pesky flyaways.

On a day-to-day basis, you’ll want to find a way to incorporate a keratin-infused product into your routine to promote the health of your hair. Suave Professionals Keratin Infusion Smoothing Hair Serum is one of our favorites. It’s a lightweight formula that will add shine to your strands while fighting frizziness.

Last but not least is Nexxus Keraphix Damage Healing Masque. This mask combines Black Rice extract, keratin, collagen and elastin to deeply condition your hair and leaves it more aligned, flexible and smooth. We recommend using this mask once a week when your hair needs a little extra TLC. The extra dose of protein is truly a lifesaver for damaged strands.
