How long before I can see my curl pattern?

I've been transitioning form relaxed hair for about 2-3 months and my new growth is driving me crazy. It some places I have really small spirals and in other places really small waves. My hair has changed so much in these past months. I realized that I have edges and my hair requires being wash every 2 to 3 days instead of once a week. My new growth acts like its weighed down. It doesn't stand up It kind of lays down.
why is my hair so different from everyone else in my family. my mom's hair is wavy and never gets super dry. while my littler sister hair is straight with two or three large curls in the back and is always dry. everyone in my family as thick wavy or straight hair
Also is it possible to wash my hair too much.
