Hair treated with keratin protein, otherwise known as the “Brazilian blowout,” has exploded into popularity. Stylists claim that it can make frizzy, wavy and unmanageable hair smooth and shiny for up to three months. But the treatment is not without its pitfalls, and it requires care on your part to keep hair looking smooth and straight.
What Is Keratin?
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.
Keratin can be derived from the feathers, horns, and wool of different animals and used as an ingredient in hair cosmetics. 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.
Benefits and results.
People who use keratin on their hair report that their hair is smoother and easier to manage as a result. The effects vary greatly depending on whether your hair is healthy to begin with, what the natural thickness of your hair is, and what kind of keratin treatment you use.
Keratin works by smoothing down the cells that overlap to form your hair strands. The layers of cells, called the hair cuticle, theoretically absorb the keratin, resulting in hair that looks full and glossy. Keratin also claims to make curly hair less frizzy, easier to style, and straighter in appearance.
How to Care for Keratin Protein Treated Hair.
▪️ Avoid getting your hair wet for three days after the treatment. This means no washing, swimming and sweating as well as staying out of the rain. Water and moisture can wash away some of the protein treatment, leaving marks in the hair.
▪️ Leave your hair down and straight for the first few days after your treatment. The keratin is still malleable, so if you put your hair in a ponytail or use a hair clip, it can leave dents in the hair. If you want to tie your hair up, wait until the keratin has been on the hair for at least three days, and then use a soft hair tie for short periods of time.
▪️ Purchase a shampoo and conditioning set that is sodium lauryl sulfate or sodium laureth sulfate-free. Both forms of Sodium Lauryl Sulfate (SLS) are powerful detergents that strip hair of its natural oils. When used with a keratin protein treatment, SLS shampoos can remove the protein and your treatment will not last as long.
▪️ Sleep on a silk pillow at night. Traditional cotton pillowcases can create friction in the hair, rendering your treatment frizzy and short-lived. Silk creates very little friction, which means a longer-lasting keratin protein treatment.
▪️ Blow-dry your hair after washing, but avoid using hair products after the initial shampoo. You don’t need root-lifting sprays, mousse, hair spray or gels to style your hair after a keratin treatment. The weight of the protein will hold your hair in the right style without the need for products, and excessive use of products could make your hair look dull and dirty. Instead, blow-dry and run a flat iron over the hair to manipulate your strands into the right style, and your keratin treatment will last longer.
Possible risks and side effects.
Salon keratin treatments contain large amounts of formaldehyde. Some employees at hair salons even reported nosebleeds and respiratory problems from handling the keratin treatment products and inhaling their fumes repeatedly over time. These levels of formaldehyde exceeded the national safety standard for chemical exposure by five timesTrusted Source. For that reason, pregnant women should avoid getting this treatment. People with a sensitivity to formaldehyde or respiratory problems should also avoid keratin treatments.
