*Hair growth tips*

I REALLY want to grow my hair long before my wedding! Any tips? I get it trimmed every like 4-5 months, I don't wash it every day (my hair is crazy, washing it every day makes it oily, and if I skip more than 1 day it gets oily). My ends are VERY dry, I use hair masks on it. "Designline Olive Oil" mask or a "Bumble and Bumble Bb While You Sleep" mask. I try very hard to keep leave in conditioner on the ends of my hair (it SOAKS up the leave in conditioner). I just don't know what else to do. Any advice for long and healthy hair would be amazing! TIA.
