Welcome and Happy Dreading.
Always, Hippie Love
Welcome. Back combing is ok. It's not the best of the starter methods, though. It puts a lot of unnecessary torque on your hair and scalp. It breaks a lot of hairs too. But it's not as bad as crocheting. TnR is a much gentler method to get your sections started.
With both TnR and back combing, locks won't form directly from those initial sections. They will untangle in the shower and straighten out again. This is normal and just fine. It happens. Starter methods only act as a blueprint for the general place you want a lock to form.
Like Adam said, 1 inch sections are the biggest most people want to go. That will result in mature locks being about the size of a quarter. When they are babies, they will seem much thinner. But as they progress, they take on the size of the section. Don't make the section too big because the baby lock seems to be the size you want it. That will change over time. Baby locks that are 1 inch in diameter will mature to be about the size of your wrist.
welcome just stop combing and let it dread or u can tnr them in
once u have a few u will always want more so u might aas well go natural and let the whole head dread
Welcome to the community. How big is are the sections at the scalp. At least one of them looks too big. The biggest you want is one square inch. If you want dreads, just Twist and rip them where you want them.
welcome but u should never get the roots done criochet was a horible mistake its extreme destruction and delays progress by 6 months
u should just leave them alone like u should have done from the srart
Welcome. The fact that they locked on their own since then proves that you never needed to crochet them in the first place. If you only did it once or twice you should be in fine shape
Welcome to the community. Crochet was a mistake in the first place. I hope that you just did it the one time and let them be. The roots never need to be done. They will grow into the dreads by themselves. All you have to do is separate when the dreads start to grow together. Just wash regularly and separate. That is all the maintenance they need.
