My hair is over 50% grey. I had light blonde hair before I became grey. I have been using Natural Palette hair color, but their lightest hair color was still very dark, almost brown. Now I have brown hair and would like to go blonde. Which hair color do I use. I would like to switch to your product, but am unsure of the hair color I should use. I was light blonde before and would like to get this color again. Thank you
