Post shower care?
First, you need to stop with the twisting. That is not dreading your hair. Besides, you are putting alot of stress and tension not only on your scalp but on your hair. Repeated twisting will only hurt you and your hair in the end. Many African Americans start their dreads by twisting, but it does nothing for causcasian hair but cause damage, and on African American hair, if constantly done...will cause the same problems. Hair will dread in its own time and in its own way. You do not need to "help it". Your hair knows what to do by itself. Dreading is a very long process for many people. I didn't have one knot for the first 8 mos. You have to be patient. The best thing you can do is leave it alone, aside from seperating after your shower. Seperating will keep the dreads from matting into a big blob...but that is really all you need. Make sure that you do not sleep on your wet hair....dry thoroughly outside or with bursts from a blowdryer. Likewise, do not put it into a ponytail or tam/hat wet. There is no magic to it. Stop looking in themirror, and don't worry about all the changes. It will look different from day to day. When it falls apart...trust that that is all apart of what it must do. Dreads are not hair that is stuck togethter, it is hair that is woven together, in its own special pattern:)
I just looked at your profile....your biggest problem is wax. Your hair will never dread as long as you are using it. You must remove the wax to progress. Hope you take some time to read about wax removal and then begin your journey fresh. Good luck and happy dreading!
