15 Best Protein Treatments For Natural Hair, According To Experts

 

Meet the key to stronger, shinier hair.

If your type-4 hair is feeling weak and brittle, chances are you need to introduce a protein treatment into your haircare routine. Why? Because protein treatments are your first line of defense against breakage and split ends, especially when you're working with already-dry hair (hi, 4a, 4b, and 4c). Protein treatments for hair help strengthen your coils by filling in any holes, gaps, and cracks along your damaged cuticle, leaving you with healthier, softer, and more resilient hair over time.

But before you run out and grab the first protein treatment you can find, it’s important to understand that (1) all protein treatments are not created equal, and (2) using them incorrectly can actually lead to more damage and breakage. So to save you from a game of trial-and-error, I spoke to two hair experts—hairstylists Debra Gomes and Leigh Hardges—to break down everything you need to know about using a protein treatment on your natural hair, plus the 15 best formulas for every coil and curl type to try right now.

Our top picks for best protein treatment for natural hair of 2023:

 

Now keep scrolling for the full list of the 15 best protein treatments for natural hair that’ll help get your hair back on track.

BEST STRENGTHENING PROTEIN TREATMENT FOR NATURAL HAIR
Verb Reset Repairing Hair Mask

Pros:

  • Clean formula contains natural, plant-based ingredients

Cons:

  • Some reviewers complain about the consistency

This protein treatment from Verb is one of Gomes's favorite picks—she says she uses it on herself and on her clients—since it's "packed with lots of nutrients, vitamins, and oils for your hair that help repair and replenish the damaged cuticle," she says. Leave it on damp, freshly washed hair for five to seven minutes and the formula's quinoa protein, green tea extract, and honey will work to hydrate and strengthen.

THE REVIEW: “Since bleaching my hair, I have used so many deep-treatment conditioners and this one is my favorite," reads a review. "It makes my hair feel so soft and silky.”

BEST PROTEIN TREATMENT FOR DRY, DAMAGED NATURAL HAIR
Briogeo Don't Despair, Repair! Deep Conditioning Mask

Pros:

  • Can be used by all hair types and textures

Cons:

  • On the pricey side

Another one of Gomes's go-tos (and a winner of our 2022 Readers' Choice Beauty Awards), this protein treatment will actually transform your dry, thirsty hair. The combo of rosehip oil, amino acids, biotin, and almond oil immediately moisturize your curls and strengthen your hair. “If your curls are lacking definition, adding consistent protein treatments to your routine will really help,” says Gomes.

THE REVIEW: "I’ve tried so many hair masks and this is the only one that I’ve ever truly been able to see a drastic difference in the moisture and strength of my hair," says a tester. "I have very dry ends, and it’s nearly impossible for me to keep them from getting frizzy or dried out, but this mask really helps.”

BEST SHINE-ENHANCING PROTEIN TREATMENT FOR NATURAL HAIR
Palmer's Coconut Oil Formula Moisture Boost Protein Pack

Cons:

  • Single-use packaging is more wasteful than other types of packaging

Strength and shine are the name of the game with this protein treatment for natural hair. With hydrating ingredients (hi, coconut oil and vitamin E) and rich proteins (like hydrolyzed silk and keratin), this formula is a no-brainer for anyone wanting to restore their hair to a super shiny and soft state. It's v reasonable too: $21 scores you a pack of 12 masks.

THE REVIEW: "I've tried literally everything to help smooth my curls and enhance their shape and nothing worked until I came across this," reads a review. "I use this treatment and then dry my hair with a diffuser and the amount of shine and you can see is incredible."

THE REVIEW: “My hair loves this conditioning mask and the smell is so divine," one tester's review reads. "I love that it's thick but not heavy—it rinses out well and doesn't leave hair heavy or with a residue.”

THE REVIEW: “I have fine, relaxed afro hair and have been struggling with damage but this seems to bring life back to my dry lifeless hair," writes one reviewer. "And you can't beat the price point."

What does a protein treatment do for natural hair?

Think of a protein treatments as intensive hair therapy—they’re filled with hydrating and strengthening ingredients (like hydrolyzed proteins, amino acids, and natural oils) that help temporarily fill in the cracks and gaps in your damaged hair cuticle so it's stronger and more resilient. With continued use, protein treatments can make hair become stronger and less vulnerable to splitting and snapping.

How can I tell my hair needs protein?

If you’re using moisturizing masks left and right to no avail, it’s time to up the ante. Hardges describes the feeling of hair that needs protein as “mushy when wet.” Additionally, if your hair easily snaps during combing and detangling, it may be time to introduce a protein treatment to your routine.

How often should I use a protein treatment?

“No more than once a month,” says Hardges. This is because too much protein can actually have the opposite effect on your hair. When protein starts to build up on the hair, it won’t allow for moisturizing and nourishing ingredients to penetrate the hair shaft; this can lead to dryness, brittleness and breakage.

What’s the difference between a protein and keratin treatment?

While keratin is a type of protein, a keratin treatment is one that’s offered in-salon and is more intense than the protein treatments that you use at home. Keratin treatments are meant to smooth the hair in a way that changes the texture, which cannot be done at home.

The in-salon keratin formulas also have much more than just protein in them and those chemicals are the ones that are responsible for the change in hair texture. You can find at-home keratin treatments (there’s one on this list, in fact), but they perform in the same way as the other at-home protein treatments, which just help to repair damage and strengthen strands.

How to choose a protein treatment for natural hair:

Hone in on your hair type

Some formulas will be way too heavy or way too light for certain hair types. For instance, 4A and up curls will need thicker, more moisturizing formulas while those on with more fine and wavy hair will want something lighter that won’t weigh hair down.

Pick your protein properly

Hardges recommends plant proteins for at-home use. In addition to plant protein, opt for a formula that also contains moisturizing agents, like oils and butters, too. Proteins and moisture go hand in hand, says Gomes, so you really want something that’s going to offer that two-pronged approach.

Remember, high price doesn't equal high quality

There are plenty of A+ protein treatments out there (many of them listed above) that come at price point that doesn't break the bank. Sometimes the simplest, least complicated formula is the one that your hair needs. So, don’t be fooled by the idea that more expensive is better, because that’s not always the case.
