The reason for me getting relaxer for the first time was because I thought it would help me grow my then natural, shoulder length hair longer. It had seemed to do that for someone I knew. It grew to my waist with the relaxer, then broke off. But I was one of those who got relaxed root to tip ever time I got it done! I decided to go back to natural hair in 2000. Now, my hair is the longest that it has ever been. It is probably two inches past my waist line right now. I'd say that I got the majority of my health and length in the last 13 months - due to the advice and inspiration from this board. I agree with what the ladies have said thus far. Also, until you get a routine down that works for you, it's really hard to tell whether or not you have reached your terminal/maximum length. Even though my hair is longer than ever before, I am not ready to say that it's as long as it is going to get because it's still growing. I would encourage you to continue what you are doing. With patience and great care, your hair will let you know when it has reached its maximum length.
