I have seen this line over the years discussed in various beauty magazines. Madonna has used it to keep her blonde hair looking fabulous. It is rumored that Jessica Alba uses some of their products. According to the before and after pictures on youtube, their dry shampoo Naturia is great for a 2 minute fix without the use of water.
I have experimented with a limited amount of their products. Most are very herbal. The line prides itself on pure essential oils and plant extracts. They are focussed on a "healthy scalp." Careful when purchasing . . . natural products do not have a good shelf life . . . call the manufacturer and confirm the product code on the bottle if you are in doubt on if the product is effective.
