Extra thick hair

I'm planning my dreads soon, but I have a delimma. My hair is incredibly thick. When it gets long, it doesn't grow down. It grows out into a pseudo-afro. can I grow natural dreads with my hair? Or if I do, will they grow out and not down?

Thanks for your help, brothers and sisters

 

once they start knotting up they should be weighted down..my hair's kinda short, so my dreadies stuck out a bit at first, but they've calmed down ..how long's your hair right now?

 

you hair is like perfect for it

 

It's about 2 inches, it should be three by next month.

 

you shouldn't have a problem..when i grow my hair out, it does become an afro. Like someone said before..the weight and length should bring it down

 

my hairs extremely thick also, & i started mine naturaly at about 2 inches..they kinda stuck out all over at 1st..but i kinda liked it..& once they got longer they settled down nicely
