If you’re someone who struggles with frizzy hair or breakage-prone hair, you probably have come across keratin treatments on your quest for a good hair day. But what is keratin, exactly, and what does it have to do with good hair?
Keratin is a protein that already exists naturally in your hair (and nails, for that matter).
A keratin treatment has become the catch-all term to refer to a hair-smoothing treatment. The exact results vary based on what type of keratin treatment you do.
There are also keratin hair products, such as keratin shampoos, conditioners, and masks, that add keratin to back into protein-depleted hair. This results in reduced breakage and smoother hair.
That depends. A stylist can consult with you to determine if a professional treatment is right for you. Our comprehensive guide to keratin treatments can help too. Where it gets tricky is with at-home keratin treatments.
If you have frizzy hair, an at-home treatment like the Tresemmé 7 Day Keratin treatment can be a good option if you don’t mind that results only last about a week. It’s significantly cheaper than a salon treatment and, apart from the flat ironing, shouldn’t damage your hair.
If you have breakage stemming from hot tools or bleaching, a keratin shampoo or mask can be beneficial as the added protein helps rebuild the structure of your hair. However, you absolutely must add a moisturizing conditioner or mask afterward. If you don’t, your hair will feel like straw.
You bet. When you have a protein overload, your hair feels dry and brittle—again, like straw. The solution is getting rid of products designed to add protein and focusing on moisturizing products instead. (A professional deep-conditioning treatment is a good idea, too.)
Look at the ingredients in your hair products. If your hair feels like straw, stop using anything that contains:
Another way to tell is to look at the hair product name. If the words “anti-breakage” or “strengthening” appear, it most likely contains protein.
