Have you tired Nature's Plus Ultra Hair vitamins?

So, i went through a bit of a hair crisis. My hair was cut unbearably short TT_TT and i want my hair to grow out as fast as possible. Do these vitamins help speed up the process a little? As of this moment my hair reaches the bottom of my ears and i want it to grow out to at least to the middle of my back by...the next school year at least.
