But there is something called protein-moisture balance, and it’s a hot topic in the natural hair community.

Why Your Hair Needs Protein

Each hair shaft is made mainly of protein, particularly keratin. Keratin keeps your hair strands strong and elastic.

So why do we need protein if our hair’s already made of it?

While hair cuticles protect our hair strands, this protection can be damaged by various things we do to our hair.

Some of our hair activities that cause cuticle damage are:

Not only that but environmental elements like sun and pollution can affect our hair too.

And when the cuticles get damaged, they open up and can no longer be effective in protecting the inner layer of the hair strands.

As a result, your hair strands will be highly porous. That means moisture and protein can easily get out of the hair shaft.

When that happens, your hair won’t have enough protein and will then be limp and brittle. 

Proper protein-moisture balance is essential for your curls to stay healthy and retain their shape and structure.

How to Know If You Need Curly Hair Protein Products

We know we said you need protein to keep your hair healthy, but you should use curly girl products with protein only when necessary.

So how will you know if it’s already “necessary”?

  • Hair feels limp.
  • The strands are stretchy.
  • Hair feels mushy when wet.
  • Your curls have loose shapes.
  • There is more breakage than usual when you brush your hair.

If you experience those signs, you may need curly girl products with protein. These will help replenish the lost protein and repair the cuticles of your hair.

How to Identify Protein Products

It’s easy to spot protein products for curly hair when the word “protein” is written on the label. You can also look for “strengthening” or “repairing.”

And if those words are not included, what you can do is go straight to the list of ingredients at the back.

Here are the ingredients to look for:

  • Soy
  • Silk
  • Rice
  • Keratin
  • Oat flour
  • Peptides
  • Collagen
  • Amino acids
  • Wheat protein
  • Any hydrolyzed ingredient
  • Milk, yogurt, or dairy-related ingredients

Those ingredients are rich in the nutrient that we need.

In addition, remember that the product ingredients are listed in the order of the highest content to the least.

So if you see the protein ingredient near the bottom of the list, that means the product only has a small amount of that said component.

We know we’re talking about protein products, but we just want to say how much we love that oat is the first ingredient listed in this shampoo.

Beware of Protein Overload

Hold it right there! Don’t get too excited about using all these protein products right away. Did you know that you can have too much protein in your hair?

That is commonly known in the curly hair community as protein overload.

Sure, protein gives your hair fullness and life, but when you overdo using many products with protein, it can give you the opposite. You’ll end up having dull, brittle, and tangled curls.

Though there aren’t many studies that prove or explain how protein overload can damage hair, people with curly hair have observed that using protein treatments excessively does them more harm than good.

Their hair easily breaks and loses its shine.

To prevent this from happening, we advise you to only use protein treatments every two to three weeks if your hair is extremely damaged. Otherwise, use the product only once a month.

As for the regular curly girl-approved protein products, use them alternately with moisturizing products because too much protein can dry your hair like the rest of the population.

Frequently Asked Questions

How Do You Get Protein for Curly Hair?

If you’re wondering how to add protein to curly hair, the first answer would be to use curly girl-approved protein products.

But aside from using hair care products that contain protein, you can also get this hair-strengthening nutrient from your diet. Eat foods rich in protein like meat, eggs, and dairy.

What Protein Makes Hair Curly?

Keratin is the protein that gives hair structure.

When your hair grows through oval-shaped follicles, the strand gets coated with more keratin on one side than the other. This is what gives your hair its curl pattern.

However, we’re not saying that when you use keratin treatments, your hair will curl. It doesn’t work that way. If you have straight hair and you want to have curls, you can get a perm instead.

Use Protein Products for Your Curly Hair Journey

For naturally curly or wavy hair, following the curly girl method is a must. That’s why it’s important that you’re aware of CGM-approved products. Your favorite protein treatment should be safe for your curls.

Remember that without protein, your hair may be weak and have low elasticity. On the other hand, when you have too much moisture than protein in your strands, you may find that your hair has gotten limp and you have loose waves.

So to help restore your gorgeous curls, find the right balance when adding moisture and protein to your hair.
