Growing your hair out

I want to know what you guys use to put in your hair when you started to grow your hair out for dreds. I have been growing my hair for 4 months and now every time I comb my hair within a hour its starts to curl up and looks really nappy. Also if my hair isn't wet when I comb it it will be impossible to comb because it will be so thick and dry. Do you have any advice for me.

My hair gets nappi after its outta water for a while, i think its natural, nothing u can do about
