I love this bar! I have quite long, fine and thick hair with a sensitive scalp that used to always itch no matter what shampoo I tried. Now my hair is really shiny, I can go an extra day between washes and my hair still looks clean and my scalp doesn’t itch at all. I live in a very hard water area and find I get no lather at all - I have to section my hair and rub the bar into my scalp to spread it well but it’s not a problem and definitely worth it! I never have any trouble rinsing it even if I use a lot - though I find the bar doesn’t necessarily last longer than a bottle would’ve.
