SALON KERATIN TREATMENTS are unrivaled in their ability to smooth and straighten hair, but they can cost upward of $300. The good news: There are plenty of at-home versions that'll save you time, money, and (bonus!) may also be better for your hair.

That said, the ones you do in your bathroom might not be quite as strong as those professional, salon-quality versions. “At-home [keratin] treatments are not as powerful, as they coat the hair rather than altering the structure of the hair, so they generally only last a week at most,” says celebrity hairstylist Andrew Fitzsimons.

But if you're more interested in making things easier on your wallet, these are the best at-home keratin treatments for smoother, softer hair.

No. 6 Bond Smoother Reparative Styling Creme

Pros

  • Top-rated among hairstylists
  • Great for all hair types

Cons

  • Doesn't actually include keratin

Rather than keratin, this treatment uses its own bond building technology to restore damaged hair along with sunflower seed, grape seed, and coconut oil to smooth and hydrate.

Rave Review: "This product gave me results after the first use! It noticeably reduced frizz when I blow dried my hair. Love it and use it every time. It does have a scent but nothing strong and I don’t mind it."

Recovery Shampoo

Pros

  • Gives the hair softness and volume
  • Great smell

Cons

  • May leave a residue on the hair

Every product in this line boasts an Alpha Keratin 60ku protein that's "identical to the keratin that makes up 90% of hair." Promising to "repave and refill keratin" with each use so your hair gets stronger and healthier over time.

Rave Review: "I have dealt with fine hair all my life and not much of it. I have been using this for almost 2 years now and I have more hair than I have ever had in my life. The keratin is donated from human hair so it bonds with the hair better than any other product. I have a full ponytail and my hair is growing. I did at first have ingrown hairs on my scalp but then it all came in. I recommend this to everyone dealing with hair loss, over processed hair, etc. You will not regret this purchase."

Leave-In Molecular Repair Hair Mask

Pros

  • Works in under 5 minutes
  • Repairs damage

Cons

  • Expensive

K18 found a peptide that could "reconnect broken keratin chains and stay put" (aka: It won't wash away with water or shampoo). The best part about this mask if that you use it in place of conditioner so you're not actually adding a step at all.

Rave Review: "My hair has been highlighted and color treated for 20 years and always bounced back after each treatment with shine. The last time I got highlights my hair got absolutely fried and my hair felt like straw in a way that I never experienced before. I tried coconut oil, other hair treatments, and nothing. I texted my colorist and told what had happened and she immediately responded with this recommendation. I have used it once and i immediately felt the difference—my hair was shiny again and back to its normal state!"

Rave Review: "It really works! I have dark, thick, wavy hair, currently with blonde highlights. My Brazilian wore off months ago and was having trouble with my rebellious long freezy bangs.

I don’t have a lot of breakage and my ends don’t get split or frail. It only takes a very small amount of this on the ends of my hair to do the trick. Highly recommend!"

How do at-home keratin treatments work?

At-home keratin treatments work wonders by harnessing the power of keratin, an important protein for hair health. "This transformative protein rebuilds and repairs lackluster hair, replenishing each strand with intense moisture and radiant shine," says Brittney Shockey, salon lead at Stonedrift Spa in Galena, Illinois. "The treatment works its magic by coating each individual strand, effectively smoothing down the hair cuticles and delivering a glossy, frizz-free finish."

What should I look for in an at-home keratin treatment?

When purchasing an at-home keratin treatment, Fitzsimons suggests looking for formulas that are formaldehyde-free. “Formaldehyde is a harmful gas that is considered to be a carcinogen,” he warns. “If you have thicker strands, you should also look for a formula that adds moisture and shine, while damaged hair could use more softening and smoothing ingredients."

How to give yourself an at-home keratin treatment?

Before performing an at-home keratin treatment, hairdresser, and founder of ARKIVE Headcare, Adam Reed emphasizes the importance of knowing that the process can easily damage hair if done incorrectly.

“It’s a long and complicated process that I would always recommend having a professional do to minimize any risk,” he says. But, if you still prefer to perform the treatment yourself, just remember that it’s vital to properly prepare your hair. Before you do anything, you should shampoo your hair thoroughly. After applying the treatment, you should leave it on for up to 30 minutes, but if you experience any burning, rinse it out immediately.

After rinsing the hair, add a deep conditioner. “Then look after it at home with a treatment like K18 and Arkive The Prologue Hair Primer,” Reed notes.

What are the potential side effects of keratin treatments?

Like any other hair process, keratin treatments also have risks when not done correctly. Some treatments can be too harsh for specific hair types and can leave hair completely damaged and brittle, which leads to more frizz and dullness. "Individuals with fine, thin hair, or heavily damaged, bleached hair are advised to avoid keratin treatments," says Shockey.
