After detangling on wash day, my hair pretty much stays detangled, but I restyle my twists every 2-3 days-there are no tangles, but I still run the comb thur each section that I am retwisting. When I did flat iron, I only had to detangle on wash day (I didn't get any tangles to remove), then I would finger style my hair after removing my hair rollers/curlers.
