11 Restorative Keratin Shampoos That Make Stringy Stands Feel like Silk

Damaged hair got you feeling down? Our best overall keratin shampoo is an essential and well-priced way to repair damage and prevent future breakage. Amika's keratin shampoo brings it back to life with a restorative mix of hydrolyzed keratin, hydrolyzed wheat protein, and avocado oil.

Not only does it provide a luxurious lather, but bond cure technology helps strengthen weak hair — it's also great for fighting frizz! Beyond keratin, there's also a blend of vegan proteins and plant butters that are rich in omega fatty acids, minerals, and vitamins to improve your hair both in the short and long term.

We love that it's the sole refillable beauty option on our list. While not a zero-waste solution, it can help cut down on plastic waste and save you some money. Hear us out: The 9.2-fluid-ounce bottle of keratin shampoo retails for $24 or $2.61 an ounce, while the 500-milliliter (16.9-fluid-ounce) refill costs $39, or $2.32 an ounce, or a saving of $4.64.

This highly rated keratin shampoo is also a favorite of Amazon beauty devotees. To quote one enthusiastic 5-star review: “We boat a lot in the summer, so my hair gets some breakage from the wind and sun. Best shampoo out there for repairing and keeping your hair soft and moisturized. The smell is fantastic, and my hubby loves it too!”

“I can safely say this is by far the best-smelling keratin shampoo on this list. Sure, the thick lather is a welcome treat, but what’s more impressive is that although I have dry hair, this shampoo never strips it of my natural oils, which is a common problem with other shampoos,” says Saunders.

Virtue's keratin shampoo has a secret weapon for treating dry, overworked hair: Alpha Keratin 60ku. This pure form of keratin is identical to the type found in your hair and nails, so it has even stronger healing power.

While we're genuinely impressed by the promising results Alpha Keratin 60ku can provide, there is a trio of other noteworthy ingredients that help enhance your healthy hair results.

Hydrolyzed quinoa is a plant-based protein that boosts your hair color, improves moisture retention, and adds shine. Baobab seed oil acts as an intense emollient for dry, damaged hair. And rounding out this powerful blend is grapefruit extract which is chock-full of vitamin C, an antioxidant that helps revitalize your scalp and leaves your hair shiny.

If your hair has suffered serious abuse from hot tools and dramatic dye jobs, then it's time to bring in this shampoo. The keratin protein- and black rice-enriched formula works well to heal the signs of damaged hair without adding any unnecessary silicones.

It also contains collagen, elastin, and an exclusive ProteInfusion blend that strengthens your hair after one shampoo by gently cleansing and penetrating hair fibers to increase your hair's resilience.

Online reviews appreciate its incredible smell and the unmistakable improvement it gave their hair. The results were so dramatic that one reviewer's boyfriend commented on the smell and appearance of their mane.

It adds the right amount of protein to my hair while maintaining the frizz-free look,” she says.

This weightless Kérastase shampoo also improves manageability and creates soft, smooth hair that is easy to detangle. We love that it's compatible with all hair textures and volumes, especially if your hair poofs up at the slightest sign of humidity.

Need more reassurance? Several Sephora reviewers promise their frizz is finally banished despite living in dry deserts or notoriously humid regions. “Living in a humid, tropical country, controlling my frizz is a must.

It’s a 10's Miracle Shampoo Plus Keratin has all of the keratin goodness your strands crave and none of the unnecessary extra ingredients.

Ulta reviewers consider Miracle Shampoo Plus Keratin a total game-changer in their weekly shampoo routine because their hair looks healthier and less frizzy. “This shampoo has certainly delivered! My hair feels SO soft, and it’s shinier than ever before,” says one Ulta reviewer.

Dealing with overprocessed, weak, or fine hair? Similar to Nexxus, this shampoo is meant for hair that needs a total overhaul. Herbalosophy’s keratin shampoo takes it from dull and brittle to healthy and shiny with an infusion of ingredients like hydrolyzed keratin and protein.

Amazon reviewers say it’s truly worth incorporating this keratin shampoo into your haircare routine. One online reviewer promises this keratin shampoo is exactly as described, while another with color-treated hair says it prevents their strands from turning brassy.

“This is truly some of the best shampoo I’ve used in a while,” says their 5-star Amazon review. “It feels creamy and rich and has a lot of lather. My hair feels clean and healthy after drying. I won’t hesitate to buy this in the future.”

The addition of natural awapuhi extract balances moisture for manageability and adds even more shine. Online reviewers say the powerful combo of ingredients has transformed their dehydrated hair.

To quote one glowing 5-star Ulta review: “I work at a salon, and this is my favorite shampoo to use when shampooing clients! The smell is amazing, and it works so well when cleaning the hair and making it feel incredibly moisturized.” They add it does an excellent job at cleaning hair, and they don’t have any dry or damaged hair after using the shampoo multiple times a week.

After carefully reviewing the key ingredients in this product, it's easy to understand why Penzi says it's her favorite budget keratin shampoo.

Note: Reviewers advise against using this shampoo if you've had a keratin treatment since OGX's shampoo contains sodium chloride that can wash it out prematurely.

Call on Keranique to revitalize thin or thinning hair. For the best results, allow this keratin shampoo to sit on your scalp and wet hair for up to 2 minutes. During that time, it removes buildup and unclogs follicles on the scalp so that healthy strands are free to grow in. Your hair will also get a heavy dose of hydration and, of course, keratin.

Online reviewers genuinely can’t get enough of this keratin shampoo. Ulta and Amazon shoppers love this product for many reasons and use words such as “great feel and smell” and “scalp soother” to describe it.

I had to cut my hair, and this [keratin shampoo] has really worked to restore my hair thickness, with new healthy growth, and restore the hair I have that was damaged from covid,” says their 5-star review.
