I hope it keeps growing!! I will say, the things that have always helped me grow my hair are: 10,000 mcg of biotin a day, shampoo twice daily with a shampoo containing tea tree oil (and follow the directors...lather, rinse, repeat) and condition once a day but leave in in longer, usually while shaving, and again with tea tree. If you have the cash Nioxin is amazing for growing hair faster, if not then Great Clips brand shampoo and conditioner is great too.
Just by doing that I went from a #2 guard to 11in in about a year.
