If you want to take a travel size bar away with you or you are not sure whether you are ready to use shampoo and conditioner bars, you can buy these 10g bars.
They come in a glassine bag, which is compostable and biodegradable.
To use your Shampoo Bar, simply wet your hair, then rub the bar over the hair a few times. Work in to a lather, then rinse. Follow with conditioner as needed. For best results, allow the Shampoo Bar to dry completely between uses
