The tests below are not an exact science but can help give you an idea of your porosity and hair width in order to better understand how to care for your hair.
Drop a strand of freshly washed (product free) shed hair in a glass of lukewarm water. After 2 minutes check to see if it is still floating towards the top of the water, hovering in the middle or sank to the bottom of the glass. If it:
- Floats = Low Porosity
- Hovers = Medium Porosity
- Sinks = High Porosity
Hair Width Test
Take a piece of shed hair and compare it to a piece of tread for a thickness comparison. If your hair is:
- Thinner = Fine
- Equal = Medium
- Thicker = Coarse
