I shaved my hair off because it was broken and damaged due to Ironing it with my hair straighteners every morning before work. Eventually my hair was in a very bad state and I figured if I shave it off then I will have a whole new head of hair. I didn't realise it would take me 4 years to get it back to shoulder length. My hair is definitely thicker and I have not dyed it and tried not to use the straighteners too much. I am trying to work with my own curls and love them again. Hope this helps you!
