Hair porosity refers to the general ability of the hair strands to absorb and retain moisture . There are three main categories of hair porosity that most hair types fit into , which are low , medium and high porosity . For doing the test ;

1 Fill a glass of water & drop a few strands of hair in it . Now observe :

- Hair floats to the top = Low porosity .

- Hair floats in the middle = Medium porosity .

- Hair sinks to the bottom = High porosity .

The other ways is - You can also test your porosity level by running a finger down a strand of your hair . Low porosity hair will feel smooth , whereas high porosity hair will feel rough and bumpy because the cuticles are open !

It is important to remember that there are no “good” or “bad” hair types, every hair is different and the key is knowledge of your hair type and knowing how best to care for the hair that you have !
