How long before my dreads lock up using the Twisting method?

It will probably take about 2 months to see real results and it will take about a year to lock up completely.

You can get extension put in before you start twisting the hair, and then twist the extensions.

Just washing, the occasional waxing, and twisting.

It is when you twist the hair into sections and then twist the hair back and forth between your fingers until it knots up.

These are the two things you should make your decision by

If the dreads get really long they can pull on the scalp if they get really long which can make you loose more hair.

Another way to look at it is that you will get to keep the hair longer, because the dreads will hold the hairs together.
