What is keratin?

Keratin is a term that anyone who is serious about their hair will have heard about and acknowledged at once stage. Without doubt, keratin is an essential part of hair health today. It’s a protein that is involved in the make-up of your hair, your skin, and your nails. Without enough keratin, your body is not going to be able to make the best hair, skin, and nails that it can. This is a vital part of modern health, then. It’s why so many people look to get keratin into their system via supplements. Let's take a further look at what keratin can do to improve the condition of our hair.

Keratin For Hair: Benefits

As mentioned above, keratin is a proven essential protein for the health and condition of our hair. Without enough keratin, you would be very lucky to have nails or skin that isn’t increasingly damaged. That’s why we recommend that if you intend on improving your hair that you get some keratin. Just some of the benefits that can be derived from getting more keratin for hair include:

  • By smoothing out our hair cuticles, keratin plays a part in making our hair look full and developed. 
  • Keratin has been linked to making our hair smoother and easier to keep in good condition.
  • The active components found within keratin are linked with stronger hair.

However, please be aware that keratin treatments have been sold as a ‘wonder solution’ for a few years now without enough evidence. You need to keep that in mind, as it’s important to remember that if your hair was already thin and in poor condition beforehand that a keratin treatment won’t always solve the problem for you. 

Keratin Side Effects

Keratin treatments are known to introduce large quantities of formaldehyde into the body. These are normally much higher than what the safety levels would suggest you should have in your body. Therefore, you should keep that in mind and if you have any sensitivity to formaldehyde, or you are pregnant, you should avoid going for the treatment.

It’s become a strong solution for sealing hair cuticles, but you should speak with a medical professional about your hair before investing in keratin treatments. It’s linked to improving our hair, but more research is needed to fully understand what it can and cannot do for us.
