Ten Effective Protein Deep Conditioning Treatments For Curly Natural Hair

(Last Updated On: March 5, 2022)

As a curly hair queen, you may start to notice excessive breakage in your natural hair. After reading many blog posts and watching countless YouTube videos, you come to realize that you have a protein deficiency in your natural hair. And now you’re on a search for the best protein deep conditioner to use to help rid your hair of this problem.

This is why in this post, I will be recommending ten highly rated protein deep conditioning treatments that are formulated to repair your hair, stop breakage, and even mend split ends in some cases.

However, before I get to recommending products, I’d first like to answer some frequently asked questions relating to the importance of protein deep conditioning treatments on natural hair.

How do I know if my hair needs protein?

All hair is made up of about 90% protein called Keratin. Overtime, due to frequent manipulation such as washing, heat styling, and other hairstyling routines, your hair will start to lose some of its protein structure.

As a result, you will start to notice your hair feeling weak, dry, and breaking excessively. When you start to experience more breakage than normal, it means your hair needs a protein treatment.

Your hair might also need a protein treatment if it feels brittle and dry. Sometimes dry hair might be due to hair damage that can only be repaired with a protein treatment, and not just with a moisturizing deep conditioning treatment.

What is the role of a protein deep conditioning treatment?

Protein deep conditioning treatments are formulated with hydrolyzed (broken down) proteins that are meant to fill in cracks and holes on your hair cuticles. They also supplement your hair with any nutrient it may be lacking so that your hair can feel nicer to the touch and continue to grow healthily.

How often should you do a protein treatment on natural hair?

If your hair is severely damaged right now and you’re finding it hard to retain length due to excessive breakage, you can do protein treatments every two weeks. You can space out the treatments every three weeks or once a month when your hair starts to recover.

The reason for this is that you don’t want to have a protein overload, whereby your hair has too much protein. You want to ensure that you maintain a healthy protein-moisture balance.

Is a protein treatment the same as a deep conditioner?

Yes, a protein treatment is a type of deep conditioner you apply to deep condition your hair in order to repair and refortify your hair. There are however a few protein treatments on the market that are stronger than a regular protein deep conditioning treatment. An example of such treatments is the Aphogee Two-Step protein treatment or the Green Beauty Channel Protein Treatment.

How do I know how much protein is in a product?

The majority of the products in this post isn’t enough to classify them as a proper protein treatment. If the protein is listed in the middle or towards the end of the ingredients list, then it means there’s little amount of protein in the product. These products are mainly moisturizing deep conditioners with some proteins in it to help with protein retention and strengthening of the hair to reduce breakage and damage.

Can I do a protein treatment and moisture deep condition treatment on the same day?

Depending on the type of protein treatment you used in your hair, you can get away with skipping the moisture deep conditioning treatment altogether. The reason is that most of the protein deep conditioners I am going to be recommending below are also formulated with moisturizing formulas that will soften and moisturize your hair after deep conditioning.

However, if the product recommends doing a moisture treatment afterward, you should immediately deep condition your hair after a protein treatment, to restore moisture back to your hair.

Can you leave protein treatments in your hair overnight?

I wouldn’t recommend leaving protein treatments in your hair overnight, as some protein treatments are potent and can result in hair damage if you leave them in for too long. I suggest following the recommended time frame on the packaging in order to get the best results from your hair treatment.

How long should you let a protein treatment sit in your hair?

I recommend about 30 minutes or whatever time frame that’s recommended by the product manufacturer.

Do I need heat to deep condition my hair?

If you will be applying a protein deep conditioner in your hair, it’s recommended that you use heat, as heat helps to speed up the absorption of proteins and other hair benefiting nutrients into your hair. If you don’t have a hooded dryer, you can use a cordless deep conditioning cap, thermal deep conditioning cap, hair steamer, winter hat, or a hair towel to generate and trap some body heat on your scalp.

What happens if my hair has too much protein?

If your hair has too much protein, you will start to experience hard hair, lifeless hair, and even breakage. This is known as protein overload. There’s nothing you can do at this point but to shampoo your hair frequently in order to get some of the protein out overtime. You can also counter the “toughness” of your hair with regular deep conditioning with a moisturizing deep conditioner such as the ones recommended in this blog post.
