The hair of your dreams awaits. Laser Hair Growth Spa
If frizz didn't exist, many of us would be happy campers. Sometimes, battling frizz can feel like a full-time job, especially when factors like humidity work against you, and buying a plethora of products to ward off frizz sometimes doesn't seem worth the trouble. Sure, the market is brimming with several quick fixes that can momentarily smooth down flyaways, like hair oils or leave-in conditioners. But odds are, if you’ve been battling frizz your whole life, you’ve heard something about keratin.
Keratin treatments are an in-salon service that reduces frizz and adds shine to your hair; they can be pricey, and when done incorrectly, potentially damaging. However, whether you opt for a salon treatment or not, you can still get the smoothing, healing, and repairing benefits of keratin right in your shower. “If you’ve got frizzy locks and are afraid to take the leap and get a full-on keratin treatment at the salon, then a keratin shampoo is a great way to start,” says Clayton Hawkins, Los Angeles-based celebrity hairstylist who counts Olivia Rodrigo and Dove Cameron as clients. Ahead, find the 13 best keratin shampoos that can alleviate frizz.
Getting a keratin treatment will make you feel like you're on top of the world. However, maintaining your treatment to prolong that feeling comes with work, specifically a proper at-home hair routine. Gussi's "protection plan" line was specifically designed to follow up the brand's own at-home keratin treatment. This shampoo adds sheen and fights frizz.
An Amazon reviewer said: “I can have the best of both worlds rocking nice curls or getting a smooth straight blow out without feeling like I’m severely damaging my hair. I was doubtful, but after 2 uses and being able to have frizz free days, I believe that this is very helpful and so much better than using products for permanent results. It was easy to use and really impressed with the results it delivers.”
The “morpo-keratine” technology in this product restores the flexibility of the hair to help create voluminous body with structure.
An Amazon reviewer says: “I started using this shampoo several months ago. My hair look healthier, shinier, and more alive. A bit pricey though but I'm happy with the outcome. It does work.”
One of Amazon’s top-reviewed shampoos, Purebiology’s RevivaHair Growth Stimulating & Anti Hair Loss formula, is packed with active ingredients to treat thinning or damaged hair. The natural extracts in the cleanser include biotin and keratin, which work in tandem to stimulate hair growth.

An Amazon reviewer says: “I purchased this at the recommendation of my hairstylist, who swears by it! The shampoo doesn't foam up as much as others, but I did notice a difference in my hair thickness and strength. Will continue to use, as hair turnover takes time to really see the full impact.”

An Ulta reviewer says: “I love the way it cleanses my hair! Has it feeling refreshed, and softer.”
Previously, if you’ve had a Brazilian keratin treatment, there wasn’t a need to use a keratin-based shampoo or conditioner, but this product works with the treatment to maintain the health of your hair and leave it feeling full and healthy longer.
An Amazon reviewer says: “I wash my hair once a week and these products keep the frizz at bay the entire time. Even when it's raining or humid out…..NO FRIZZ! I highly recommend Pure Brazilian.”
If keratin alone isn’t enough to get your hair back on the road to good health, the extra oomph of super-moisturizing coconut oils will take you the distance. The other notable ingredient is avocado oils—you hear that, millennials?
An Amazon reviewer says: “This is my go-to rescue for my dry breaking hair. It really works.”
The keratin used in Virtue’s shampoo is identical to the keratin produced by the human body. This cleanser also works to rid strands of excess oil, dirt, and build-up in a gentle way that won’t damage or strip vibrancy from color-treated hair.

“Keratin helps to rebuild the protein structure of your damaged hair,” says Hawkins. “Over time, it should leave your hair silky and smooth.” It's something our body creates naturally. “Our hair, skin, and nails are made up of keratin,” says Lam. “The more do to our hair–such as coloring or heat styling it—the more it can weaken and appear dull.”
“If you’ve got frizzy locks and are afraid to take the leap and get a full-on keratin treatment at the salon, then a keratin shampoo is a great way to start,” says Hawkins. If you already have a keratin treatment, “Keratin shampoos help protect your investment by prolonging the smoothness of the cuticle,” says Perteet.
Even if you have un-treated hair, keratin shampoos can still help keep frizz at bay. “If you have frizzy/coarse hair texture, keratin shampoo is a great option to help smooth your hair,” says Rasmussen. “Over time it creates a coating on the hair that will help fill in the pores in your hair to make it smooth and shiny.”
