I would also be concerned about the breakage. For years I wore twists and would wash them first and then take them down - waiting between 2 weeks to a month to do this. I no know that was way too rough a form of manipulation for my hair as I would force my way through those twists and break apart what was essentially becoming starter locs. And I did this regularly too.

Now I keep my twists big and loose so I don't have to break through them anymore. Already my hair has responded to this with added length and easy handling. If you're breaking up locs regularly, its a lot of stress on the hair.
