Many times people go natural to get away from the chemicals, not realizing that the “natural” products they are turning to are higher alkalinity and completely destroying porosity(the ability to retain moisture) Products that are high on the PH scale can open/swell the cuticle and keep it open. This leaves the cortex vulnerable to the environment, heat, products oils...etc... if the cuticle isn’t sealed back down it can’t actually hold moisture.
This is not to say that you should not go natural. It is merely pointing out that natural is not automatically healthier if you are using highly alkaline products.
Porosity is simply the hair’s ability to retain moisture.
The Ph of the hair will determine your hairs porosity.
Healthy hair and scalp ph sits at between a 4.5 and a 5.5
Chemical processes like relaxers and high lift color are high on the ph scale. Some reaching as high as 9-11...this means that it is fully swelling the cuticle to get to the cortex and rearrange and/or break hair bonds.
Using higher alkaline products on your hair on a regular basis, can be just as damaging as using the previously mentioned chemicals.
All roads lead back to balance and sealing that balance in. if the PH is raised, it must be regulated to stay healthy.
Here’s an article that will give you a little more clarification on PH
