your doing fine just separate often enough and do it while wet or damp at least.
you shouldn't have clearly seen sections . thats typicaly the result of early traction alopecia
the hairs will cover your scalp like it should
separating you will have new dreads born from time to time
the only time you should ever need scissors is if you went way too long without separating
way too long.. in fact thats a last resort when you try everything else possible to separate
try separating after each wash if your using dreadlockshampoo liquid try the bars instead (since your in crochet recovery phase)
the faster its dreading the mor you got to separate.. mine i only separate after using the liquid (once every couple months) the rest of the time (being mature) they almost never need any at all
but for 18 years i separated just absentmindedly feeling around for any that needed it not on a schedule just when my brain was engaged in other things..
i stopped then and let as many as 6 become 1 and only separate thicker ones (and on occasion thinner depending what feels right) once mature if yu want to let some combine thats just fine
till then separate as often as you need even for some going natural and dreading fast..a few times a day till mature
post some pics lets eee whats going on
27 years growing dreadlocks the natural way
My dreads are over 9 feet long
