I have been trying to grow mine back out, as well. I had long, long hair until I decided that I wanted to be platinum blonde and bleached it. Due to breakage I had to cut it off....and I miss it. I have been taking Collagen supplements (with added Biotin) in hopes it will work. Its slowly, slowly growing back...but I sure do miss it. However, I can't go back to brunette after tasting 'the blonde life' lol. Transformed my entire look. It's also pretty disheartening that every man feels the need to tell me how much sexier long hair is....
