High porosity hair has gaps and holes in the cuticle, which allow too much moisture into your hair and releases moisture quickly. It is the result of chemical, mechanical, or heat damage.

Color treating your hair requires that the hair’s cuticle be lifted in order to alter the melanin in the strands, and even though the cuticle is closed after the hair is rinsed and conditioned, the damage is already done. When your hair breaks easily with minimal effort, it is a sign of improper protein and moisture balance, so this will require incorporating protein-rich products into your regimen.
Soggy and limp strands that hyperextend while wet are evidence of worn elasticity. This occurs when there is damage to the cortex, which cannot happen unless there is damage to the cuticle as well. Using heat styling tools too frequently also damages the cortex by melting the keratin in the hair and chipping the cuticle.
Style your hair however you want, but know the risks and how to take care of your hair accordingly.
