No I haven't but I do plan on trying it this weekend but I braided my roots so they aren't just plan twists. I do understand your concern. When I wash my hair or just let too much water hit my hair my roots unravel. Actually my roots unravel when I sweat too much now that I think about it.
So I can let you know how steaming in braided twists work out if you are interested. I have a feeling I will need to coat them in oil first, then condition and then steam.[/QUOTE
I have steam with two strand twist and your roots will unravel ( well mine did), so if you have a style that you don't want to redo....... I would recommend that you wait until you are taking down your twist and then wash, DC and steam.
