Sisal Soap Saver Loofa Bags made from 100% natural plant fibers that come from the leaves of the Agave Cactus are a great companion to Hair Rocks Solid Shampoo bars. These bags have a natural warm tone and have never been bleached or dyed. The textured bag helps you get the most foaming action from your Hair Rock by creating luxurious long lasting lather without wearing down your rock too quickly. Biodegradable Compostable Sustainable Once your bag is worn out just toss it into your compost bin. How to use: Add a whole Hair Rock solid shampoo bar to the bag or those rocks too small to hold onto. Lather and wash hair. *once the lather appears on the sisal fibers you can remove the rock and place it on your soap dish to dry and use the bag as a glove to scrub your scalp and clean your hair. Rinse and hang up bag to dry between uses. *if you leave the rocks in the bag it may not fully dry and will wear down the rock too fast.
