You’ve probably heard about keratin as an anti-frizz method or a way to boost your hair’s health, but does keratin treatment straighten hair?

Keratin treatment is a popular way to get frizzy, thick hair to lie smooth and straight. If your hair can be a bit wild and unmanageable, a keratin treatment might be your solution.

Does Keratin Treatment Make Hair Straight?

Keratin isn’t a straightening treatment like rebonding but yes, It helps your hair look straighter. For wavy and curly hair, you can get straighter hair using keratin treatments.

The keratin treatment adds keratin to your hair that makes the hair smoother, shiny, frizz-free, and strengthened. So, the hair looks straighter but it doesn’t necessarily straighten hair as it does in treatments like relaxer or rebonding.

The keratin within the treatment isn’t what truly straightens the hair. Think of it as the healthy base for the chemicals that help the hair stay that way. It’s the heat styling and professional care that straighten the hair.

Keratin is a protein found naturally in nails and hair, so adding a treatment to your hair will help improve your hair’s overall health and texture. Many hair products have keratin as an advertised ingredient for this reason.

You can get various hair treatments at a salon or perform at home, but the most common one is the Brazilian Blowout. This is done at a salon by a professional who applies a keratin formula to your hair for 20-30 minutes.

Once the formula has been processed and rinsed, your hair is blow-dried and straightened using a flat iron. Afterward, you leave your hair alone entirely for a few days, and you should have a straight, glossy finish to your hair.

The longevity of the blowout varies from person to person since we all live different lives and have varying hair types.
