If you’re looking for a damage-reversing treatment for your hair, the K18 Leave-In Repair Hair Mask is a great option. There’s a lot of debate on whether K18 rivals the efficacy of Olaplex. While it definitely has a higher price point, it’s argued to be one of the best treatments for extremely dry and damaged hair.

The Thank God It’s Natural Miracle Repairx is one of the best protein treatments for damaged, curly, and brittle locks. It contains avocado oil, jojoba oil, cocont oil and several other nourishing oils. Its protein source is hydrolyzed wheat protein and it uses glycerin for extra hydration.

This protein treatment is best for curly, dry and damaged hair because it removes buildup while restoring protein so the mane becomes soft and healthy.

The treatment is highly-rated and well-loved with many fans online who swear by it. It adds plenty of slip and defines curls. It reduces breakage and is ideal for hair that needs moisture, especially in the cold months.

It does contain fragrance but users say it smells amazing so it shouldn’t be a problem unless you’re quite sensitive to scent. It’s affordable, too, and you get 12 ounces of product in the tub.

This product is better for thick hair as some people with fine hair have remarked that it left their hair frizzier. It contains oils but is not moisturizing enough, according to some users.


EVO Mane Attention Protein Treatment

The EVO protein treatment is another addition to the best protein treatments to consider. It’s an intense protein reconstructor,another term for a bond repair conditioner. It contains glycerin, macadamia seed oil, jojoba seed oil, shea butter, hydrolyzed quinoa, and hydrolyzed soy protein.

You can also find fragrance and dimethicones on the list, which isn’t promising if you’re a fan of the curly girl method.

This promises to be a treatment for “hair that’s been put through the wringer” and users have professed that it is a lifesaver for damaged, chemically-treated hair. It turns brittle, frizzy hair into the soft, silky strands of your dreams and cuts down on blow drying time.

This product has your back if you’re maintaining blonde locks. It makes hair more manageable and combable and offers UV protection.

However, since it contains silicones, this may leave hair feeling heavy, especially if you have fine hair. The scent may be a hit or miss, depending on your taste.

I love the hygienic packaging (no more dipping dirty fingers in a tub) and it only takes 5 minutes of use to soften the locks.

Aphogee uses a unique two-step process for their protein treatment. This is one of the best treatments for natural hair.

The hair protein treatment is used to prepare the locks before a perm, bleaching, straightening or relaxing session. You can also use it to encourage the hair to retain color before dyeing or to restore your curl pattern.

It contains hydrolyzed collagen, magnesium and activated proteins and reduces breakage for 4 to 6 weeks after use.

The hair protein treatment is applied to towel dried hair using a wide tooth comb. Afterward, the treatment is left on the locks and blow dried with a regular blow dryer or a hooded dryer until the hair hardens like uncooked ramen. Then, you rinse it off and follow up with a conditioner.

The packaging has a flip top opening that evenly disperses product. Many people with African-American and damaged hair loved this salon service product and while it’s not the most afforable, it’s worth every penny.

Aphogee can improve the product by removing the orange color, which can tint light hair. You also have to apply conditioner after as it’s not moisturizing. It also has a strong scent that is quite unpleasant for some.

If you’re looking for a deep conditioning treatment, this is one of the best ones to buy. It contains shea butter, glycerin, coconut oil, mafura oil, baobab oil, and reparative proteins. All these ingredients will brign life back to dry, damaged hair.

It doesn’t end there, though, because this also has antioxidant manuka honey and yogurt powder and extract. The deep conditioning treatment has strengthening properties, perfect for brittle, vulnerable strands. It repairs breakage and split ends while softening the locks.

Manuka honey gives a healthy shine while yogurt adds a dose of moisture. Mafura oil takes care of damage control and revives your hair.

This repairing treatment has a thick consistency that’s perfect for types 2A to 3C hair. It melts into the locks upon application. It rinses out well despite its creamy texture so you don’t get nasty product buildup that’s a nightmare for fine hair.

I really like that it’s an affordable protein treatment but sadly, it only contains 8 ounces of conditioner and you need quite a lot. It’s also lighter on the protein so it’s not good for hair that has extensive damage.


Redken Extreme CAT Anti-Damage Protein Reconstructing Treatment

Another well-loved protein treatment is the Redken Extreme CAT Anti-Damage Protein Treatment. It contains hydrolyzed wheat protein, which is second on the ingredient list.

This is a hair mask treatment that softens brittle and damaged locks without weighing them down. It uses patented taurine technology and cationic proteins which reconnects bonds so the cuticle lies flat, lending a healthy, smooth appearance to the mane.

The rinse-off treatment gives noticeable results after rinsing and prevents further breakage. It also contains ceramides and lipids that will strengthen the hair from the inside and shield it from damage.

You can use this ahead of hair dyeing to prep the locks. It is meant to be applied after shampoo but before conditioner.

Redken has other products in the Extreme range, which can be helpful if you want to have a complementing set of treatments. The bottle contains only 5 fluid ounces, which makes the price a bit steep.

The treatment is a spray, so it’s not moisturizing at all. It’s meant to be used as a first step before a conditioner. Application is a bit tricky since it’s a liquid and some have noted that it’s best applied on towel dried hair, which is an extra step some may find inconvenient.

While the results are not overnight, users have said their hair is remarkably healthier and softer after consistent use.


A Buying Guide to Protein Hair Treatments

Is a protein treatment good for hair?

Protein treatments are good for some types of hair. It’s not a must-do treatment for all hair types because some people just don’t need more protein on their mane. Just because your hair feels dry doesn’t mean it needs protein. Oftentimes, it just needs moisturizing ingredients to replenish lost oils.

However, if you are dealing with the issues below, consider getting a protein treatment at home or in the salon.

Signs that you need a protein treatment

  1. You have decreased hair elasticity.
    To check your hair’s elasticity, do the stretch test. Take a hair strand and pull it in opposite directions with your fingers. You may need to pluck out a strand to do this properly.
    Healthy hair stretches but snaps back into its original length but if your hair is damaged or dry, it will not regain its shape and may even break off.
  2. You have colored hair.
    Color-treated hair is susceptible to damage because of its high porosity. Your locks are also more damage-prone if it has gone through bleaching, exposure to pool chlorine, and chemical treatments such as perms and relaxers. These treatments leech off protein from your hair, leaving it more vulnerable through cracks on the hair surface.
  3. You’re experiencing hair loss and breakage.
    If you have more hairfall than usual with the strand broken off, instead of being uprooted from the follicle, that’s a sign that your hair needs strengthening via protein. Use it if deep conditioners don’t help.
  4. You have limp and lifeless strands.
    Flat hair that doesn’t hold curls or waves well will benefit from a protein treatment. Protein plumps up stringy hair so it doesn’t look as lifeless.
  5. You have high porosity hair.
    You can check if you have porous strands by filling a bowl with some water and placing a strand of hair on it. Porous hair will sink into the bottom.
    Highly porous strands have gaps that lets it absorb too much water, leading to frizz, tangles and breakage.

What are the benefits of protein treatments?

A protein treatment will strengthen hair, just as eating protein-rich foods help us grow stronger. They benefit damaged hair by increasing elasticity and making the cuticle smoother.

A protein treatment also promotes hair growth, adds volume, reduces frizz, enhances shine and defines curls. It can even benefit a dry scalp.

It imparts all these benefits by infusing hydrolyzed proteins into the cuticle and fortifying the surface of the hair strand. Protein acts as a shield from further stressors and damage by patching up cracks on the cuticle.

What’s in a protein treatment? How can I tell if a hair product contains protein?

Protein treatments are labelled as strengthening or repairing masks or conditioners. They contain ingredients like minerals, essential fatty acids, amino acids, vitamin E, and hydrolyzed proteins.

The most common protein treatment ingredients are wheat, silk, keratin, oat, rice and collagen. Look out for the keyword “hydrolyzed” because it signifies that the protein has been turned into smaller particles for faster absorption.

Other protein treatments are more straightforward and include protein on the label or on the ingredients list.

How often should I do a protein treatment on my hair?

The frequency of a protein treatment depends on your hair type and the treatment itself.

Homemade treatments are applied once or twice a month. Professional, salon-quality protein treatments are used less often, around every four to six weeks.

Less intense treatments can be used every one or two weeks.

Go slow, at first and work your way up to a frequency that feels right for your hair.

Check the manufacturer’s instructions for guidance.

Take care not to overuse protein treatments. There is such a thing as too much protein. If you overdo it, your hair will feel brittle and dry and may break off easily.

You have to stay vigilant about your hair conditioner after using a protein treatment and reduce the frequency if your hair condition doesn’t improve.

What’s the right way to use a protein treatment?

A protein treatment is applied on clean and freshly conditioned hair and washed it off. You may use it as a hair mask and leave it on for a longer period or about an hour.

Usually, though, a protein treatment soaks in for twenty to thirty minutes before it’s rinsed out. Fine hair types can even skip the conditioning step and use the treatment right after shampooing.

There are also other forms of protein treatments, including shampoos and leave-on creams.

How to Choose the Best Protein Treatment for Hair

Hair Type

You need to assess if you need a protein treatment and why you need one in your haircare routine. Look through the aforementioned signs of damaged and lackluster hair to check if you’re a good candidate for a protein treatment.

If you’re experiencing breakage, you also need to find out the cause. Sometimes, it may be due to a nutritional deficiency instead of lack of protein.

Product Type

You should then determine what form of protein treatment you’d like to apply to your hair. Most protein treatments come in a hair mask delivery system but there are other forms as well.

Ingredient List

Look for the sources of protein in the formula by checking the ingredients list. The inclusion of hydrolyzed protein, amino acid, or any protein is a good sign.

Make sure there’s enough protein in the formula, as well. If it’s in the first six ingredients on the list, it’s a significant amount to get you good results.


The treatment should strike a balance of protein and moisture to avoid overdrying your strands. Too much protein is actually bad. You should not use pure protein on your hair because it will be too intense.


As always, consider the price of the product compared to the amount you’re getting (also known as cost per ounce or mL). Make sure the ingredients are of high quality, regardless of cost.
