POROSITY and CURLY HAIR: How does it affect my curly hair?

POROSITY is another way of describing the hair's internal structure 
and its ability to absorb, hold or lose water.
More damage more porosity Less damage less porosity.

Most curly hair looks better when it's wet as water contains the most numerous bonds H2 O2 but are also the weakest in the hair and that is why it looks good when it's wet. When the water evaporates the hair appears puffy and frizzy.

Unruly curly hair being more porous means more water is absorbed adding more weight, holding down the curls, having more control. This type of curl, requires styling products that are thicker and have more weight to maintain the control. Some products even add oils to increase weight along with polymers to set the style and create a humidity barrier.

Fine softer weaker curls that have too much porosity means, it will absorb too much water making the hair hang limp. For this type of curl, look for styling products which contain magnesium sulfate which tends to dry and tighten the curls squeezing out water reducing weight and increasing the curl. Simply by replacing the water with protein treatments can fill these voids with a structure allowing the hair to become less porous.

Getting the balance is not that hard, if you understand the concept. Porosity can be you hairs best friend or worst enemy.

Therefore, styling products can seal the hair to maintain the moisture inside the hair which it loves.
