Should I be retwisting or palm rolling?

I started my dreads a week ago with tnr method. Im trying to achieve thin near sectioned dreads so I can cornrow or twist if I want to. Do I need to palm roll often our retwist often to accomplish this? Thanks for the responces in advanced.

nooooooooooooooo retwisting causes traction alopecia and balding (so will cornrowing if left in long at all)

palm rolling weakends the roots too but retwisting is wayyy worse never retwist

thatys why nearly everyone with salon dreads looks like they are going bald with all that exposed scalp between them

Dang. Are there any good ways to keep the dreads sectioned or is this just one of those decide if its worth the risk type things?

just seperate pull them apart sometimes its called popping or ripping

Just let em go. They'll love you for forever. Dreads are meant to be a bit chaotic and your scalp loves to hid underneath them in the shade when the sun comes out!
