to "get your sections right" let your hair section itself
thats the only way to get them right according to what your hair wants to do
you go to a pro and they will section them rigidly in squares so every dread w3ill be exactly the same and boring
plusd they will charge u a reddiculouse amount of money
if u let them do anything more then just section they will screw u up totakly
really the best way to dread is let it dread
welcome do not go to a pro they will screw u u should not crochet or wax the best way is natural ..neglect or tnr going to a pro is the worse thing u can do!
