Does My Hair Need Protein or Not? The Ultimate Guide for Curly Hair

Curly hair is beautiful, unique, and versatile. But to keep your curls looking their best, balance in your hair care routine is essential. Many women with curls focus mainly on hydration, which makes sense, since dryness is often a challenge. However, there is another crucial element your hair can’t live without: protein.

Protein for your hair plays a key role in the health of your curls. In this blog, we’ll explain everything you need to know: what protein does for your hair, how to tell if you need it, which protein hair products are best, and how to use them correctly within your CG routine.

What is Protein Exactly?

Hair protein is a natural building block of your hair. Your hair is mainly made up of keratin, a type of hair protein that provides structure, strength, and elasticity. Without enough protein, your hair loses these properties  and curly hair shows the effects quickly.

When your hair is damaged by heat, coloring, brushing, weather conditions, or even over-moisturizing, tiny cracks form in the hair shaft. Protein hair products help fill in these gaps and restore strength to your strands.

Why is Protein So Important for Curls?

Curly hair is more fragile than straight hair. Due to its natural curl pattern, the outer layer (cuticle) often remains slightly open, allowing moisture to escape more easily and making hair more prone to damage.

What many don’t realize is that a lack of protein in your hair can be just as problematic as a lack of moisture. In fact, limp curls, poor definition, or excessive frizz are often caused by protein deficiency, not dehydration.
A good protein treatment for curly hair can make the difference between dull, lifeless strands and bouncy, healthy curls.

How Do You Know if Your Hair Needs Protein?

The classic question: Does my hair need protein? The answer lies in learning how to “read” your hair.

These are the signs of protein deficiency:

• Your curls look limp and have lost their bounce

• Your hair feels overly soft or stretchy

• Little to no curl definition, even after styling

• Hair breaks easily when brushing or combing

• Persistent frizz, even in humid weather

• Products seem to stop working effectively

If you notice several of these, it’s time to add protein products into your routine, such as a protein hair mask or a protein refresh spray.

How Do You Know if You Have Too Much Protein?

Just like with hydration, it’s all about balance. Too little protein makes your hair weak and limp, but too much can make it dry, stiff, and brittle.

Signs of protein overload include:

• Hair feels dry or straw-like

• Curls are hard to style and lack softness

• Hair looks dull, stiff, or without shine

• More breakage than usual

If this happens, pause protein use, deeply hydrate your hair, and then reassess.

The Balance Between Protein and Moisture

The so-called protein-moisture balance is essential for healthy hair. Think of it like a scale:

• Too much moisture = soft, limp, shapeless hair

• Too much protein = stiff, dry, brittle hair

The secret is alternating strengthening and hydrating products. For example: after an intensive protein hair mask, always follow with a deep moisturizing treatment. This keeps curls both strong and supple.

Types of Protein Hair Products

Not all proteins are the same – each has different benefits. Here are the most common ones in CG-approved products with protein:

Choose a CG-approved conditioner with protein, a gel, or a refresh spray with protein, depending on your hair type and porosity.

How to Use Protein Hair Products

An effective protein treatment for curls doesn’t have to be complicated. Follow these steps:

1. Evaluate your hair type & condition – fine or coarse, low or high porosity, natural or chemically treated

2. Start gently – try a protein refresh spray and observe the results

3. Add deeper treatments – use a protein mask once a week

4. Always hydrate after protein – with a moisturizing mask like our Intense Moisture Deep Conditioner

5. Adjust with the seasons – summer often requires more hydration, winter more protein for breakage prevention

Common Mistakes with Protein Use

• Using protein too often without hydrating

• Combining products that cancel each other out

• Ignoring porosity or hair type

• Stopping too soon if hair feels dry at first

• Assuming all curls need lots of protein – it varies per person
