High porosity hair is damaged hair. The water glass won’t actually tell you much. Easier way to tell is how healthy your hair is. Low porosity hair is not damaged, shiny, and has a healthy cuticle (under a microscope.) Medium porosity is slightly damaged, has less shine and hydration. High porosity hair is damaged, breaks easily, dry, frizzy, etc. And depending on the natural texture of your hair and the thickness of your cuticle different treatments, products, and routines will work better for you. But if you want to improve your hair, do minimal protein, do lots of hydration, less heat, less processing/styling, eat a healthy diet with healthy fats, keep your scalp clean and hydrated, and avoid chemicals. It will be a bit different for everyone, but those are the basics from what I have learned.
