Our picks for the best protein hair treatments
Olaplex is a pretty well-known name when it comes to haircare. The hair perfector is a protein treatment you can use once a week or as often as three times per week, if your hair is pretty damaged. It’ll strengthen your hair and cut back on strand breakage. Plus, you’ll notice an overall improvement to your locks after use.
The brand recommends you pair it with the bond-building hair treatment for best results. Doing so is worthwhile, though, because it means your hair could get up to three times stronger, according to the brand. The hair perfector is also free of gluten, nuts, parabens, phthalates, phosphate, and sulfate. Olaplex is also focused on formulating products while cutting back on its carbon footprint by reducing packaging.
Size: 3.3 fl oz | Hair type: All
Palmer’s makes an affordable protein pack that helps repair your damaged, dry strands. It’ll give you a boost of moisture after you wash and condition your hair. Just leave it on for two or three minutes and rinse it off for smoother, shinier hair.
The pack may be a bit small for those with extra luscious or long locks, though, and the brand recommends you use its conditioner for best results. However, it’s a great option for an inexpensive protein treatment without a significant commitment to a full bottle.
Size: 2.1 oz | Hair type: Dry or damaged
Yes, GK Hair’s protein treatment is a splurge. However, if you plan to use it often, it comes in a jumbo size, which can be worthwhile. And it’s salon-quality, so stylists use it on their clients. It contains keratin, which gives damaged or frizzy hair a smoother look.
This treatment also produces longer-lasting results — as long as six months after applying it. That definitely makes this a splurge-worthy pick if you’ve got damaged hair in need of some TLC.
Size: 10.1 fl oz | Hair type: All
Noticing that your strands are breaking off easily? Reach for this masque with nourishing shea butter and Jamaican black castor oil, which will give you more elasticity. That also means a bit less shedding, along with softer, shinier hair.
You’ll need to wait at least 10 minutes for this treatment to work its magic, and you’ll have to sit under a dryer. However, that’s a great reason to pamper yourself for a few extra minutes this weekend.
Size: 12 oz | Hair type: Multiple
If your main concern is damaged hair that needs some repairing, try this treatment from Aveda. Though not ideal for people with dry hair, it offers a deeply repairing protein treatment that smells amazing. After using it, you’ll walk away with less frizz and stronger hair.
Made with quinoa protein, organic jojoba, and organic castor oil, it also has that luxurious Aveda scent. It’s cruelty free, and you’ll only need about two minutes to apply it before reaping the benefits.
Size: 4.2 oz | Hair type: Damaged
L’Oréal is an icon in the beauty industry, and its products are pretty easy to find on drugstore shelves. We’re big fans of this fact and the price of the brand’s protein treatment. It’s a conditioner you just apply and leave in, making it super convenient to use.
Don’t apply too much, though, as some reviewers have noted a little goes a long way. And that little bit of product translates to heat protection and up to 97% less breakage, according to the brand.
Size: 5.1 fl oz | Hair type: Damaged
Coloring and highlighting hair can equate to damage over time, which is why this protein hair treatment is so great. It’s color-safe, and it doesn’t have any sulfates, parabens, phthalates, or gluten.
One packet provides up to three applications, so it won’t last terribly long. Still, the price is quite reasonable, and you only need to leave it in your hair for 10 minutes or less. It’ll deeply condition your hair and restore its smoothness and shine. It’ll also add hydration while repairing damage, thanks to the keratin. It even reduces static — a major plus since winter is on the horizon.
Size: 1.75 oz (pack of 12) | Hair type: All
If you’re not interested in adding an extra step or two to your haircare routine, this set is for you. Vegamour is a vegan company, and this kit includes a shampoo and conditioner containing a vegan keratin formulated by the brand. The shampoo coats your hair with protein while the conditioner locks in moisture and keeps your hair shiny.
It’s on the more expensive end of the spectrum, and some reviewers described the texture as sticky. Nonetheless, it’s a great protein hair treatment that could cut back on your signs of shedding by up to 76% after five months of use.
Size: 2 bottles (8 fl oz each) | Hair type: Multiple
For hair in need of hydration, try this protein treatment from Thank God It’s Natural (Tgin). It strengthens your hair while also smoothing your strands. The protein works to build up your hair so it breaks less, and you don’t lose as much of it.
Plus, it adds much-needed hydration to your scalp and boosts hair growth. It’s not a gluten-free product, but it steers clear of parabens and sulfates. To use it, just leave it on your hair for about three minutes and rinse — simple, fast, and effective.
Size: 12 oz | Hair type: Multiple
Many protein hair treatments need to be applied and rinsed off after you’ve already washed and conditioned your hair — but not this one. Use this treatment before you shampoo to avoid having to hop back into the shower to rinse out your treatment.
The Curlsmith salve will make your hair stronger while also repairing any existing damage. Plus, you can use this whether you have hair that’s porous or not. The brand includes specific frequency instructions depending on your hair type, making it a more personalized experience.

How to pick the right protein hair treatment for you
We spoke with Dr. Cory Gaskins, M.D., with Skin CV to learn more about protein hair treatments. When selecting the best product for you, Dr. Gaskins suggested to take certain factors into account like how porous your hair is, its elasticity, and whether or not it’s dry.
Hair type
- Porous. With highly porous hair, you can get away with more frequent protein treatments.
- Elasticity. This addresses how easily your hair breaks, which impacts how often you should try treatments.
- Moisture. People with dry hair shouldn’t get protein treatments as often.
FAQs
What’s the best professional protein treatment for hair?
You’ll want to consider a few factors about your hair before settling on a treatment. For instance, Dr. Gaskins told Glowsly that “if your hair is very dry, you may have to get this treatment as infrequently as possible: from a few weeks to every other month because protein treatments can be quite drying.
Are protein treatments good for your hair?
“Protein treatments can help to restore damaged hair by filling in the gaps in the cuticle. This can help to make your hair look and feel smoother and shinier,” Dr. Gaskins said. However, using protein treatments too often could make your hair dry or even brittle.
What’s the best protein pack for hair growth?
According to Dr. Gaskins, “The best protein pack for hair growth is the keratin K31 treatment. This treatment is designed for bleached or damaged hair, and it works by infusing protein into the hair shaft. The result is stronger, healthier hair that can better withstand damage.”
