Type 4 natural hair is characterized by its tight curls and coils. It is
often divided into subtypes:
4A: Tight, defined curls
4B: Z-shaped curls with less definition
4C: Extremely tight coils with minimal definition
Hair Porosity and Its Impact
Hair porosity refers to your hair's ability to absorb and retain
moisture. Understanding your hair's porosity is essential for healthy
hair growth. There are three porosity types:
Low Porosity: Hair cuticles are tightly packed, making it hard for
moisture to penetrate.
Normal Porosity: Hair cuticles are moderately spaced, allowing for
adequate moisture absorption.
High Porosity: Hair cuticles are widely spaced, leading to quick
moisture loss but easy moisture absorption.
Knowing your hair's porosity can help you choose the right products and
care routine for optimal hair health and growth.
How to Calculate you Hair Porosity
Gather Your Supplies
For this experiment, you'll need:
A clean glass of water
A strand of your hair
Step 2: Fill the Glass
Fill the glass with room temperature water. Ensure it's not too hot or too cold.
Step 3: Place Your Hair
Gently place a strand of your hair on the surface of the water.
Step 4: Observe and Wait
Observe how your hair reacts:
If it sinks immediately, your hair may have low porosity.
If it floats for a while before sinking, your hair may have normal porosity.
If it stays afloat, your hair may have high porosity.
