Protein and Low Porosity Hair: What You Need to Know

October 10, 2025 Michelle Duff

When it comes to low porosity hair, protein is a double-edged sword. While some hair types thrive on regular protein treatments, low porosity hair often reacts differently — and not in a good way. If your strands feel stiff, dry, or resistant to moisture after using certain products, you may be dealing with protein sensitivity.

🧬 What Is Protein Sensitivity?

Protein sensitivity occurs when your hair becomes dry, brittle, or hard after using products that contain proteins. For low porosity hair, this is especially common because:

The cuticles are tightly sealed
Proteins can't easily penetrate the strand
Excess protein builds up on the surface, causing stiffness and breakage

Not all low porosity hair is protein-sensitive, but many people with this hair type experience negative results when protein is overused.

⚖️ Low Porosity and Protein: Finding the Balance

It’s not about avoiding protein entirely — it’s about knowing when and how to use it.

✅ Use proteins sparingly

Look for hydrolyzed proteins that are broken down into smaller particles (e.g., hydrolyzed wheat or silk protein). These are easier for low porosity hair to handle — but still only occasionally.

❌ Avoid heavy protein masks and treatments

Especially ones with keratin or collagen. These can overload your strands quickly and lead to dryness or breakage.

💧 Focus on moisture first

Hydration should be the main goal in your low porosity hair routine. Protein should never replace regular moisturizing steps.
