If Your Hair Could Talk, It Would Say: "Hey, I Need Proteins!" And no, not the kind from your post-workout shake, but the ones that help your hair stay strong, shiny, and resilient.
Are you wondering what exactly this protein balance is and why your hair needs it? Don’t worry, we’ll explain everything in detail in this article:
- The role of proteins in the hair fiber
- Signs of an imbalance (deficiency or excess of proteins)
- Different proteins used in cosmetics and their benefits
- The importance of restoring a good balance between proteins and hydration
Proteins & Hair: Why Are They Important?
Your hair is largely made up of keratin, a protein that provides strength and structure, making up about 85 to 90% of its composition. However, between blow-drying, straightening, coloring, and even pollution, this keratin gets damaged, leaving your hair weak, limp, or brittle. In short, it's crying out for SOS!
To prevent this, your hair needs a boost—but not just any boost! It requires the right balance between hydration and proteins. Trust me, once you find the perfect equilibrium, your hair will regain its strength and stay in top shape!
How to Tell If Your Hair Lacks (or Has Too Much) Protein?
Your hair is just like you—it needs variety! Too much protein makes it stiff, rough, and brittle, while too little protein leaves it limp, elastic, and lacking volume.
If your hair stretches too much before breaking, it means it's weakened and lacks structure, much like an over-worn sweater that starts losing its shape. In this case, it needs protein. This issue is especially common in chemically treated hair (bleaching, straightening, perms), which has undergone damage to its natural keratin.
If your hair is dry and breaks easily, it’s like modeling clay left out in the open—it hardens, becomes fragile, and crumbles easily. This is likely due to an excess of protein, meaning your hair needs more hydration.
The goal is to find the right balance—for hair that is strong yet flexible, shiny but not stiff, and healthy without being overloaded.
Which Proteins for Which Needs?
Not all proteins are the same! Depending on their molecular size, origin, and solubility, they have different effects on the hair.
❖ Hydrolyzed Proteins (Small Molecules, Deep Penetration)
- Hydrolyzed Keratin : Strengthens the hair structure and restores damaged cuticles.
- Hydrolyzed Collagen : Improves elasticity and moisture retention.
- Hydrolyzed Silk Proteins : Provide softness, shine, and protection against humidity.
Best for: Highly damaged, colored, or chemically treated hair.
❖ Intact Proteins (Large Molecules, Surface Action)
- Wheat Proteins: Create a protective film and increase hair’s mechanical resistance.
- Rice Proteins: Boost volume and hair density.
- Oat Proteins: Improve softness and reduce hair porosity.
Best for: Adding volume and protecting normal to dry hair.
How to Build the Foundations of an Effective Treatment?
Now that you understand why this step is essential, the next challenge is adjusting it wisely. Spoiler alert: it’s not an exact science! Everything depends on your hair type, its current condition, and what you put it through.
Listen to Your Hair: The Signs Don’t Lie
Don’t Neglect Hydration
A protein treatment alone isn’t enough—it must always be paired with proper hydration. Think of a brick wall (proteins): without cement (hydration), it’s at risk of collapsing! After a protein treatment, apply a hydrating mask to keep your hair soft and prevent the dreaded "straw-like" effect.
Yes, Your Diet Affects Your Hair Health!
The proteins in your hair (keratin, elastin, collagen) are formed from amino acids, so consuming enough of them in your diet is essential.
Foods to Prioritize:
- Lean meats and fish (chicken, salmon, sardines)
- Eggs (rich in biotin and complete proteins)
- Nuts and legumes (almonds, lentils, chickpeas)
- Dairy products and protein-rich alternatives (Greek yogurt, cheese, fortified plant-based milk)
- Marine or bovine collagen supplements (boosts hair structure and growth)
Tip: A diet rich in zinc, iron, and B vitamins (found in leafy greens, seeds, and seafood) also helps your body absorb and utilize proteins more effectively for healthier hair.
Protect Your Hair to Prevent Protein Loss
Even if you use the best protein treatments, they won’t be effective if your hair loses proteins too quickly due to bad habits.
How to Preserve Your Hair as Much as Possible
✔ Must-Do Tips:
- Use a heat protectant before any heat styling.
- Avoid washing too frequently to maintain natural protein levels.
- Sleep on a satin or silk pillowcase to reduce friction and prevent breakage.
Tip: You can also seal in hydration with a light oil (argan, jojoba, or grapeseed) to keep your hair from drying out between protein treatments.
Find Your Balance: Alternate Between Protein and Hydration Treatments
Keeping your hair balanced is like managing your diet—you can't live on fast food alone, but you also can't survive on just salads. It’s all about a smart mix! The key is to maintain a steady protein intake without overloading your hair.
