Be healthy and treat your hair well and you can maximize the amount of growth, but ultimately how fast your hair grows is due to genetics.

So just be patient, get trimmed when you see split ends so it doesn't look shaggy or frizzy, and I'm sure you happen to know a black girl (or a white or brown girl with curly hair that uses the same routine) with natural hair that can give you tips about washing and moisturizing your hair to preserve and encourage length.
