Not totally convinced! You soon will be once you try our testers for not much more that a cup of coffee. The testers usually provide approximately 5-7 washes depending on your hair type & length. (The Conditioner will last way longer as it doesn't lather ) Please read the instructions on 'How to Use' and don't forget if you have any questions we are just a phone call away. Don't forget to get them free draining in between washes to get the most out of your Bars. Please also remember that your bars are not soap based. Using soap on your hair is an absolute NO NO !  We still see some Companies market soap bars as Shampoo bars and that makes us really sad.
