Post that bad hair cut hun, we won't laugh -- promise!
Biotin is great for hair and nails though and it's really cheap. It's the key ingredient in most expensive hair growth compounds. My sister used it when she went natural/big chopped and her hair grew like crazy.
Some of the cell rejuvenation benefits from fish oils, vitamin C, and CoQ10 may help with more rapid hair growth, but it's not going to be a dramatic change that they will bring about by any means; they just help.
