Porosity and Protein: The Delicate Dance (and How to Get It Right)

Hair care can sometimes feel like a science experiment, with a dizzying array of products, treatments, and techniques to choose from. But two crucial factors can make all the difference in achieving healthy, strong, and vibrant hair: porosity and protein. Understanding how these elements interact is essential for maintaining optimal hair health. In this guide, we’ll delve into the delicate dance between porosity and protein and how to strike the perfect balance for your hair type.

What Is Hair Porosity?

Understanding Hair Porosity

Hair porosity refers to your hair’s ability to absorb and retain moisture. It’s determined by the state of your hair cuticles, which can be tightly closed, slightly open, or very open. There are three levels of porosity:

  1. Low Porosity: Cuticles are tightly closed, making it difficult for moisture to penetrate but once it does, it stays in.
  2. Medium Porosity: Cuticles are slightly open, allowing moisture to be absorbed and retained more easily.
  3. High Porosity: Cuticles are very open or damaged, allowing moisture to enter easily but also escape quickly.

How to Determine Your Hair Porosity

A simple way to test your hair porosity at home is the “float test.” Take a few strands of clean, dry hair and place them in a glass of water. Observe what happens:

  • Low Porosity: Hair floats on top.
  • Medium Porosity: Hair hovers in the middle.
  • High Porosity: Hair sinks to the bottom.

Personal Anecdote: When I first did the float test, I was surprised to find my hair floating on top, indicating low porosity. It explained why heavy creams always left my hair greasy and weighed down. Adjusting my hair care routine to focus on lighter, more penetrating products made a world of difference.

The Role of Protein in Hair Care

Why Protein Matters

Protein is the building block of your hair, providing strength and structure. Hair is made of a protein called keratin, which needs to be replenished regularly, especially if you use heat styling tools, chemical treatments, or color your hair.

Signs of Protein Deficiency and Overload

  • Deficiency: Hair feels weak, limp, and overly stretchy. It may break easily and lack volume.
  • Overload: Hair feels stiff, dry, and brittle. It may snap when you try to stretch it.

Balancing Porosity and Protein

Low Porosity Hair

Characteristics: Tightly closed cuticles, resistant to moisture absorption.

Challenges: Product buildup, difficulty in moisture penetration.


  • Use lightweight, water-based products: These penetrate the hair shaft more easily.
  • Incorporate humectants: Ingredients like glycerin and aloe vera attract moisture to your hair.
  • Apply heat: Use steamers or warm towels to help open the cuticles and allow products to penetrate.
  • Clarify regularly: Remove product buildup to keep hair clean and receptive to moisture.

Expert Insight: “For low porosity hair, it’s important to use protein sparingly and focus on moisture.” – Shari Harbinger, Co-founder of DevaCurl.

Medium Porosity Hair

Characteristics: Cuticles are slightly open, allowing for balanced moisture absorption and retention.

Challenges: Maintaining the balance between moisture and protein.


  • Alternate products: Use moisturizing and protein treatments in a balanced routine.
  • Deep condition regularly: Keep hair hydrated without weighing it down.
  • Use lightweight oils: These help seal in moisture without adding too much weight.

Expert Insight: “Medium porosity hair is the sweet spot. It’s versatile enough to handle a variety of products and styles, but it’s important to maintain a balance of moisture and protein to keep it healthy and happy.” – Ayanna Pressley, Natural Hair Influencer (Source: The Cut).

High Porosity Hair

Characteristics: Cuticles are very open, often due to damage, allowing moisture to enter and leave quickly.

Challenges: Dryness, frizz, and breakage.


  • Use heavy creams and butters: These help seal the cuticle and retain moisture.
  • Incorporate protein treatments: Strengthen the hair shaft to reduce breakage.
  • Layer products: Apply leave-in conditioners, oils, and creams to lock in moisture.
  • Avoid excessive heat: High porosity hair is already prone to damage, so minimize heat styling.

Expert Insight: “Protein treatments can be beneficial for high porosity hair, as they help to strengthen and repair the hair shaft. However, it’s important to use them in moderation, as too much protein can lead to dryness and breakage.” – Aishia Strickland, Natural Hair Expert and Founder of Aishia Strickland Hair (Source: Essence).

Research Insights

The Impact of Protein Treatments on Different Hair Porosity Levels

This study would investigate how various protein treatments (e.g., hydrolyzed proteins, keratin treatments) affect hair with different porosity levels (low, medium, high). It would assess the impact on hair strength, elasticity, and overall health to determine the most suitable protein treatments for each porosity level.

The Relationship Between Porosity, Protein, and Hair Damage

This study would examine the correlation between hair porosity, protein levels, and different types of hair damage (e.g., breakage, split ends, dryness). It would aim to identify optimal protein-to-moisture ratios for different porosity levels to minimize hair damage and promote overall hair health.


Understanding the delicate dance between porosity and protein is essential for maintaining healthy, strong, and vibrant hair. By identifying your hair’s porosity and incorporating the right balance of moisture and protein, you can achieve your best hair yet. Remember, your hair’s needs may change over time due to environmental factors and treatments, so be prepared to adjust your routine accordingly.

With the right knowledge and products, you can master the art of balancing porosity and protein, ensuring your hair remains healthy, hydrated, and full of life. Happy hair care!
