The buzz around the admittedly splurge-y Virtue Recovery Shampoo is due to one key ingredient: Alpha Keratin 60ku, a human keratin protein trademarked by Virtue that has impressive damage-repairing and hair-strengthening benefits. According to the brand, studies for the ingredient have shown 95% less split ends, a 22% increase in hair thickness, and hair color that's 138% more vibrant, while studies for the shampoo itself showed softer, more manageable hair and less damage. The sulfate-free formula also contains other moisturizing and shine-enhancing ingredients, like baobab seed oil and grapefruit extract.

The difference this shampoo has made is remarkable! Well worth the price to me to have my shiny, healthy hair back. Love it!”

In Palmer's Coconut Oil Formula Conditioning Shampoo, coconut oil and monoï oil work together to restore softness and moisture to curly hair that's become dry or damaged. Other key ingredients include vitamin E, which helps prevent against breakage, and keratin protein for even more strengthening benefits. But perhaps best of all is the great value you get with this shampoo: For just $10, you'll get not one but two big bottles, so you'll be stocked for ages.

Formulated with fine hair in mind, this shampoo from OUAI — celebrity hairstylist Jen Atkin’s wildly popular product line — nourishes and adds volume to hair that’s thin, weak, limp, or just in need of a boost. Strengthening ingredients like keratin, panthenol (aka vitamin B5), and biotin help to repair damage and split ends (and though the science is iffy, anecdotal evidence points to biotin helping with hair growth), while chia seed oil offers further moisturizing benefits. When you run out, don’t throw out the bottle — instead, invest in the eco-friendly refill pouch so you can keep topping up your bottle whenever it gets low.

Key Ingredients Keratin, Biotin, Panthenol, Chia Seed Oil Sulfate-Free? Yes Cruelty-Free? Yes

Olaplex is best known for their iconic No. 3 Repairing Treatment, the product that put the brand on the map (and launched them into countless luxury salons across the globe). But their Bond Maintenance shampoo, and its matching conditioner, are just as deserving of your attention. Both products harness Olaplex’s unparalleled bond-building technology — which is the only bond builder with a patent — to repair split ends and strengthen damaged hair that’s become weak, brittle, and dry. In turn, they also help promote smoother, shinier hair that looks and feels healthier.

You can use both products as frequently as you want, or you could alternate with a less-expensive repairing shampoo/conditioner if you want your bottles to last you longer.

Key Ingredients Bis-Aminopropyl Diglycol Dimaleate Sulfate-Free? Yes Cruelty-Free? Yes

Relevant review: “I’m in shock at how quickly this stuff worked. I’d heard about Olaplex for a while, so I finally caved and bought it. For the first time in idk how long, my hair didn’t feel like straw as soon as I took it out of the towel after my shower. My ends are almost back to a normal state and don’t feel as dry. I’ve used this stuff once and I’m in awe. My hair is shiny and smooth for the first time in a long time.”

If it’s not in your budget to splurge on Olaplex, you can try L’Oreal’s bond-building shampoo and conditioner instead. Though it doesn’t use the same technology as Olaplex, it does work similarly in that it helps to repair broken bonds that have become weakened due to things like dyeing your hair and frequently using hot tools. Also like Olaplex, it strengthens your hair so it’s less susceptible to future damage — though unlike the salon-favorite brand, L’Oreal’s two-piece set rings up at less than $15 on Amazon.

Key Ingredients Aloe, Sunflower Seed Oil, Rosemary Leaf Extract Sulfate-Free? Yes Cruelty-Free? No

Relevant review: “I can’t say enough good things about this line! You’ll think it is high end hair products & it’s so affordable…it leaves my hair silky smooth & smelling great! Great for any hair type but it really helps my frizzy hair & smooths my split ends.”

“I bleach my hair, so I’m always dealing with damage to some extent. Pureology’s Strength Cure shampoo helps mitigate that damage, however — considering how often I chemically treat my hair, it should be in a lot worse shape,” says Elite Daily beauty editor Adeline Duff. “Not only does this shampoo smell great, keep my wavy hair smooth, and cut down on both frizzies and split ends, but it also ensures my color stays vibrant between salon visits, thanks to the brand’s signature AntiFade complex, which can be found in all their products.”

Pro tip: For best results, follow up with the matching leave-in conditioner.
