I use this bar as shampoo and face wash. I LOVE it! I tried diluting the liquid tea tree soap but was having trouble getting the right pH so I would have really oily or really dry hair but the bar does all the work for me. It's perfect. I think it's a great alternative to washing with plain baking soda. Baking soda makes my hair clean and look great but my scalp is really sensitive, not only to sulphates but also baking soda and it makes my scalp break out. Plus it lathers just like regular shampoo which helps clean your scalp especially if you have long hair. I follow the tea tree soap with apple cider vinegar rinse or a very small amount of silicone free conditioner and my hair is amazing.
