For a whole year I was suffering from brittle ends, and I discovered that the only way to keep my ends from braking in little half inch pieces is by moisturizing EVERYDAY. Which isn't impossible, just not fun to do with a foot of hair lol. So I plugged in my symptoms and it took me to porosity. Now I already knew I had low porosity hair. However, when I read through it again a year later, I discovered more than I did then. So I started using glycerin, and ever since then, my hair has been staying moisturized. I've gained 3 inches, since then, so I'm hoping to get to waist length this year! But with low porosity you never know what's going to be thrown at you next lol ^_^
