Porosity, Density, Elasticity Tests

Porosity:  Determines how your hair absorbs water. Knowing hair porosity will allow you to assess how healthy the cuticle of your hair strand is. Use this knowledge to help decide what products would be best for your hair.

  • Test Your Porosity:
  1. On freshly washed clean hair (without product), gather one strand of hair
  2. Place it into a bowl of water
  3. Observe the hair for up to one minute to see if it floats. Hair should not sink. If it does, the hair is porous.
