MooGoo's Milk Shampoo is one of their most popular products and was originally made for a family member with an itchy scalp. Combining 5 natural cleansers that foam up well, although the foaming action isn't quite as intense as it would be if a synthetic detergent like SLS or SLES was used. MooGoo was happy to make the small trade-off to use ingredients that are healthier for us and the environment. Ever think about what happens to your wash products after they go down the drain? Silicones and synthetic ingredients don't break down into their natural components easily in the water system.
