Hair porosity refers to how well your hair can absorb and retain moisture. How porous your hair is has a lot to do with which no poo method will work best for your hair. Figuring out your hair porosity will allow you to maximize the benefits from your conditioning products.
How Porous Is My Hair?
It’s super easy to test the porosity of your hair.
Method #1: The Float Test
- Fill a glass or bowl with room temperature water.
- Take a couple strands of your clean hair and put them in the water. Clean hair is important. If you have oils or products on your hair, it will alter your results.
- Watch it for 2-4 minutes.
- If your hair sinks immediately, it has high porosity. Your hair absorbed the water quickly and sank quickly.
- If your hair is still floating 4 minutes later, it has low porosity. I have low porosity hair (see my float test pic below).
- If your hair is slowly sinking, you have normal porosity.
Method #2: The Slide Test
- Grab a strand of hair on your head.
- Starting from the end of your hair, slide your fingers up the hair shaft towards your scalp.
- If you have a bumpy ride, you have high porosity hair. If your hair felt smooth, you have low porosity hair.
Method #3: The Spray Bottle Test
- Take a small section of your hair and pin the rest back.
- Spray that section with a little water, just enough to mist it.
- If the water sits on top of your hair or beads up, you have low porosity hair.
- If your hair absorbs the water quickly, you have high porosity hair.
- If the water sits on your hair for several minutes then is absorbed, you have normal porosity hair.
NOTE: The “how to care” tips below are not set in stone rules. Everyone is different. For example, I have low porosity hair but my hair responds well to a coconut oil hair mask. Coconut oil is a heavy oil and does not do well on most low porosity hair in general. All of the tips below are “in general.”

Traits of low porosity hair:
- Cuticles are closed, so moisture does not enter easily / resistant to moisture
- Products sit on your hair
- Does not absorb hair color or treatments easily
- Water beads up on hair
- Hair takes a long time to dry
- Looks healthy but doesn’t have much elasticity or volume
How to care for low porosity hair:
- Use heat to open the cuticles to let the moisture in (hot water, heated deep conditioners, etc.). If you aren’t opposed to the hair dryer, you can use it to heat your conditioner while it is on your hair. Or wrap a hot towel around your head (heat the towel in your clothes dryer).
- Use lighter products. Argan oil and grapeseed oil are good light oils.
- Reducing build up is key. Build up on low porosity hair makes it more difficult for the moisture to make it’s way to your hair. Washing with clay and apple cider vinegar is a good way to remove build up on low porosity hair (see the no poo methods for more info).
Traits of high porosity hair:
- Absorbs too much moisture, but is unable to retain it
- Looks and feels dull and dry
- Generally damaged and over processed with torn cuticles (but not always)
- Tangles easily because the cuticles get caught on each other
- Hair dries quickly
- Tends to be frizzy
How to care for high porosity hair:
- Egg washes are great for high porosity hair. The protein in the egg restores and strengthens the cuticles. But do not do it too often. Too much protein will cause your hair to become stiff and break. See more under “egg wash.”
- Aloe vera gel and coconut oil are great for high porosity hair
- Heavy products and cream work well for high porosity hair
- High porosity hair benefits well to deep conditioning products to help restore and heal the damaged cuticles
Traits of normal porosity hair:
- Absorbs and retains the perfect amount of moisture
- Shiny, healthy, lots of volume
How to care for normal porosity hair:
- Keep doing what you are doing! Your hair is healthy and happy. Unless you are transitioning to a no poo, nontoxic method. In general, your transition will be relatively quick and easy.
