By December I want bra-strap length hair. I pulled out some of my hair from a protective style I have been wearing and I flat ironed it, believe it or not that piece of hair was almost touching the top of my tank and my tank has a low but not bra-strap length collar. I have about 4 inches to go for bra-strap length, I will settle for 2-4 inches, I haven't been taking my vitamins reguarly, but I have been using my biotin filled products and washing and moisturizing frequently.
