Holy Grail item for me. I swapped over to these bars around April, started with the orange blossom. It was gunky the first time I used it until I followed with a conditioner and vinegar rinse. Never got that icky feel again. Used that for over a month and preceded onto the grapefruit bar. For me, that one adds body but I lose a bit of hydration. I've only used the charcoal three times so far. That one feels wonderful for the scalp, incredible really, and does an out-standing job at cleansing the hair. It doesn't seem quite as nice for building up the body of my hair as my favorite, the orange.
My hair is thicker, shinier, more manageable and has hardly a split end. A HUGE deal for me is the affect on the greys I have. I don't have a huge amount, but they came in kinky and very noticeable. As these are growing out, the new (grey) hair coming in is smooth and shiny. As my hair is half way down my back, there is a noticeable line which hair has never been touched with a sulfate shampoo and which has.
Hope I'm making sense - I have one eye turned to the Olympics!
