I use the sink most of the time. I only use the shower when I am on my last step and planning on showering. I tried the shower when I first joined LHCf but it seemed to take forever, was a pain getting in and out and it didn't seem to help me any.
Sometimes I wash my hair loose and sometimes I put in barrettes to keep it separated. My hair is SL. Maybe its not long enough to tangle badly. Its definitely not long enough to put into twist or braids to shampoo.
Maybe when my twists are longer, I may try the shower but for right now the sink is just easier and more convenient.
