How long before my dreads lock up using the Twist & rip method?

It will probably take a year to a year and a half for the dreads to lock up. I have heard in certain rare cases with people with extremely curly or textured hair that the dreads can lock up in 8 months, but that was something I only heard from one person.

Just washing the occasional waxing and the daily twisting the hair around and ripping it apart.

It is when you rub all your hair in s clockwise motion and once you get a big nest of knotted hair ripping it apart into sections.

I wouldn't use the circular rubbing method if you hair is thinning or it runs in you family for hair to thin. Because you will actually be pulling the hair out and it will most likely damage your hair follicles.

This method will work on African textured hair.

It will probably be very hard to dread that hair type with this method. You probably will want to go with a method that has to lock up, like backcombing.
