aren't dreads like... really bad for your hair? probably not but ive heard that you arent supposed to wash your hair or some shit, someone wanna inform me?
i don't have 'dreads' per se but i never comb my hair and haven't gotten it cut in 3 years... so as you can imagine i've got several natty lock type things that have kinda shown up over time haha
2" is pretty short... dreads look silly when the person has short hair. They're best when all your hair is at least past your shoulders (IMO of course, you can do whatever you like!).
i remember i was at a festival one time and a guy was talking about his dreads, said he got them when his hair was pretty short, like just getting into his face he referred to them as 'buckwheat ass dreads' hahahahahaha
