Keratin is the type of protein that makes up your hair, skin, and nails. Keratin can also be found in your internal organs and glands. Keratin is a protective protein, less prone to scratching or tearing than other types of cells your body produces.

Since keratin is the structural building block of your hair, some people believe that keratin supplements, products, and treatments can help strengthen your hair and make it look healthier.

Salon keratin treatments
Sometimes called the Brazilian keratin treatment, this time-intensive method of using keratin involves several steps. First, a cream that contains formaldehyde is applied to your hair before it’s blown dry and straightened in a salon. Once the treatment is applied, you’re instructed to keep your hair dry for several days. When you visit the salon to have the chemicals washed out, another treatment is applied to “set” the straightening effect. This treatment claims to last for 12 weeks.

Keratin treatments do have some benefits. By applying keratin to your hair cuticle and sealing it in with heat, your hair takes on a glossier appearance. But before getting a treatment like this, it’s critical to understand the chemicals involved. Some people may find that after they get a keratin treatment once, they have to keep getting the treatment so that the heat damage from processing their hair this way doesn’t show. Keratin treatments also expose hair salon employees to high levels of chemicals that are toxic over time.
