The Porosity Myth Busters: Separating Fact from Fiction

Understanding hair porosity has become a popular topic in hair care discussions, but there’s a lot of misinformation out there. Porosity refers to your hair’s ability to absorb and retain moisture, which can significantly impact how your hair responds to products and treatments. Let’s separate fact from fiction and bust some common myths about hair porosity.

Myth 1: Hair Porosity is Static

Fact: Hair Porosity Can Change

It’s a common misconception that your hair’s porosity is set in stone. In reality, it can change over time due to various factors such as environmental conditions, chemical treatments, and even your hair care routine. Dr. Rolanda Wilkerson, a board-certified dermatologist and hair loss specialist, explains, “Hair porosity isn’t a one-size-fits-all concept. It can vary along the length of a single strand and change due to environmental factors.”

For instance, frequent coloring or bleaching can increase your hair’s porosity by lifting the cuticle layers, making it more prone to moisture loss. Conversely, consistent use of deep conditioning treatments can help reduce high porosity by filling in gaps along the hair shaft.

Personal Anecdote

I used to think my hair was low porosity because it took forever to dry. However, after a year of regular coloring, I noticed my hair began to feel drier and needed more moisture. It was a clear sign that my porosity had changed due to the chemical treatments.

Myth 2: The Float Test is the Only Way to Determine Porosity

Fact: The Float Test is One of Many Methods

The float test, where you place a strand of hair in water to see if it sinks or floats, is widely touted as the go-to method for determining porosity. While it’s a helpful indicator, it’s not foolproof. Ebony Bomani, a licensed cosmetologist and founder of The Mane Choice, notes, “The float test is a helpful indicator, but it’s not the only way to determine your hair porosity. Consider your hair’s overall behavior and response to products for a more accurate assessment.”

Other methods include the strand test, where you run your fingers along a strand of hair to feel for bumps (indicating high porosity), and simply observing how your hair reacts to moisture and products. Does your hair dry quickly? Does it absorb products easily? These are all signs that can help you determine your hair’s porosity.

Personal Anecdote

I tried the float test, but the results were inconsistent. Sometimes my hair floated, and other times it sank. It wasn’t until I started paying attention to how my hair responded to products and moisture that I got a clearer picture of my porosity.

Myth 3: Low, Medium, and High Porosity Require Completely Different Products

Fact: There’s Overlap in Hair Care Needs

While it’s true that different porosity levels can benefit from specific products, there’s significant overlap. For example, all hair types need moisture and protein to some extent. Nayamka Roberts-Smith, a licensed esthetician and founder of LABeautyologist, emphasizes, “Don’t get too hung up on porosity labels. Focus on understanding your hair’s unique needs and finding a routine that works for you.”

For low porosity hair, lightweight, moisturizing products that can penetrate the cuticle are ideal. High porosity hair benefits from heavier, sealing products that lock in moisture. However, all hair types can benefit from regular deep conditioning and avoiding harsh chemicals.

Personal Anecdote

I used to buy products labeled specifically for low porosity hair, thinking they were the only ones that would work for me. But I found that some products meant for high porosity hair, like certain deep conditioners, actually worked wonders for my hair’s health.

Myth 4: Porosity is the Only Factor That Matters

Fact: Hair Density and Texture Also Play a Role

While porosity is crucial, it’s not the only factor determining how your hair responds to products. Hair density (the number of strands on your scalp) and texture (the thickness of each strand) are also important. Penny James, a trichologist, explains, “While porosity plays a role in moisture absorption, other factors like hair density and texture also influence how your hair responds to products.”

For example, fine hair might get weighed down by heavy products, regardless of porosity, while thick hair might need richer formulas to feel hydrated.

Personal Anecdote

My hair is fine but high porosity. I initially used heavy creams and oils to combat dryness, but they made my hair limp and greasy. Switching to lighter, more hydrating products made a huge difference.

Myth 5: There’s a Magic Bullet for Porosity Issues

Fact: Consistent Healthy Hair Habits Are Key

No single product or treatment will magically fix all your porosity-related issues. Consistent healthy hair habits are crucial for maintaining the balance your hair needs. Kerry E. Yates, a trichologist, states, “There’s no ‘magic bullet’ for porosity. Healthy hair habits, like regular deep conditioning and minimizing heat styling, are essential for all hair types.”

Regular trims, protective styles, and minimizing chemical treatments can also help maintain your hair’s health and manage porosity issues.

Personal Anecdote

I used to hop from product to product, looking for a quick fix for my high porosity hair. It wasn’t until I committed to a consistent routine of deep conditioning and protective styling that I started seeing lasting improvements.

Research Insights

Longitudinal Study on Hair Porosity Variability

A longitudinal study on hair porosity variability could provide valuable insights into how hair porosity changes over time. By tracking individuals with different hair types and textures, researchers could determine how environmental factors, chemical treatments, and hair care practices influence porosity fluctuations.

Impact of Hair Porosity Misdiagnosis

Another important area of research is the impact of hair porosity misdiagnosis. This study could examine the consequences of using unsuitable products based on incorrect porosity assessments. It would assess the impact on hair health, moisture balance, and overall satisfaction with hair care routines. The study could also explore strategies for accurate porosity determination and personalized product recommendations.

Practical Tips for Managing Different Porosity Levels

Low Porosity Hair

  • Use Lightweight Moisturizers: Products with humectants like glycerin or honey can penetrate the cuticle without weighing down your hair.
  • Apply Heat: Use a steamer or warm towel to help products absorb better.
  • Clarify Regularly: Remove product buildup that can prevent moisture absorption.

Medium Porosity Hair

  • Balance Moisture and Protein: Alternate between moisturizing and protein treatments to maintain strength and hydration.
  • Regular Deep Conditioning: Keep your hair soft and manageable with weekly deep conditioning treatments.
  • Protective Styles: Minimize manipulation with styles like braids or twists to prevent breakage.

High Porosity Hair

  • Use Heavier Products: Butters and oils can help seal in moisture and reduce frizz.
  • Protein Treatments: Strengthen your hair with regular protein treatments to repair damage.
  • Avoid Excessive Heat: High porosity hair is more prone to damage, so limit heat styling and always use a heat protectant.


Understanding hair porosity is a valuable tool in your hair care arsenal, but it’s not the only factor to consider. By debunking these common myths and focusing on healthy hair habits, you can create a routine that works for your unique hair needs. Remember, it’s not about fitting your hair into a specific porosity box but about finding what makes your hair look and feel its best.

“Hair porosity isn’t a one-size-fits-all concept. It can vary along the length of a single strand and change due to environmental factors,” says Dr. Rolanda Wilkerson. Embrace your hair’s uniqueness, and give it the care it deserves.
