Getting older can change the structure of your hair. Gray starts coming in, you loose some hair. Me, well when I was a child, I had extremely straight hair..as a teen, I permed my hair on a constant basis until I was about 18, but then my perm lasted for years! All of a sudden I had curly hair! So, of course I started coloring plus the fact that I used tons of styling aids, and always in the sun. Our hair goes through a lot of abuse. Since I lost all this weight, my hair started falling out and breaking off. This can happen when you make such a drastic change in your lifestyle....
