Low Porosity vs. High Porosity: Which One Are You?

What Is Hair Porosity and Why Does It Matter?

Hair porosity refers to how well your hair can absorb and retain moisture. It plays a major role in how your hair reacts to products, humidity, and even heat styling.

There are three porosity types—low, medium, and high—but most people fall into low porosity or high porosity without realizing it.

How to Tell Hair Porosity: The Float Test

The hair porosity test is simple and can be done at home:

1. Start with clean, dry, product-free hair.

2. Drop a strand into a glass of water.

3. Wait 2–4 minutes.

Results:

• If your hair floats, you likely have low porosity hair (moisture has a hard time entering).

• If it sinks quickly, you likely have high porosity hair (moisture enters easily but escapes just as fast).
