Testing your hair porosity is important in determining how to care for your natural hair. Porosity is how your hair absorbs water. Learning your hair porosity will provide an in-depth look on healthy the cuticle layer of your hair is. With the knowledge about hair porosity you can use appropriate hair products and correct the overall health of your hair.
Wash and condition hair. Dry hair with a towel or T-shirt. Do not add any products to your hair.
Separate hair strands and gather one strand. Capture the hair strand with your index finger and thumb.
Run your index finger and thumb up the hair shaft. Start at the end of the hair and run down to the root.
Determine hair porosity. Overly porous hair catches down the hair shaft. Normal porous hair is smooth down the shaft, and low porous hair feels slick.
Take the time to repeat Step 3 over and over again, and then determine your hair porosity.
