What Should I Do With My Hair !!?

Im a 14 year old black girl. I just took my micros out a week ago and my hair is really thick. Im trying to go natural for the summer and there is no way imma cut my hair again. I used to have hair that went to my shoulder but i had to get it cut. My hair is in the buddy beauty transition stage. I use organic hair mayonnaise, coconut oil, and this Argan Oil Proclain Hair Oil Treatment. I have no idea how to keep my hair moisturized. I use Pantene Pro-v for Relaxed & Natural Hair. I dont know if im doing a good job or not. I just want my hair to grow because i hate short hair on me ! I just want to keep it natural for the summer. It gets hard to keep up with during the school year. I usually do weave, relaxers , or braids during the school year... Thank Youu For All Thaa Help !!:)
