I started mines back in April and mines are growing graciously, if you're planning on doing it completely organic like Bob Marley or The Weeknd then you should stop picking with your hair and stop spraying it, it'll probably cause build up.
All i do is lay on my hair, if you keep twisting it and picking at it it'll only interrupt the natural matting. That's literally all you have to do for 3-4 yrs, after about 2-3 months after you stop combing your hair you'll start feeling the dreads form and you'll have tight coils all over your head like corbin bleu, they'll later grow into dreads if you leave them alone.
When i wake, before i go out i wet the sides with water and finger comb before i go out, i shampoo it every 2-3 day's so i don't wash out all the natural oils unless i've been sweating all day. When washing try to avoid touching the coils and scrub the scalp directly or soak your hair, stop using conditioner, shampoo only. You're gonna have to pat dry or air dry your hair to avoid interrupting the free form process.
I also moisturize with natural Coconut Oil to avoid dandruff problems, you can find it at the grocery store next cooking oils for around $4.99. It also has a shyt load of other natural uses (oil pulling, healing scars, eczema, etc...). Coconut oil is good for your body in genral, completely edible also so you can cook with it too.
