Not wanting to sell you water (we are sure you have plenty of your own!) The Bluebeards Revenge have simply taken the very best, salon quality shampoo they could find and concentrated it to within an inch of its life. Be careful when you use it as you will probably need far less than you think! Whatever you do keep out of reach of the fairer sex as, sure as eggs is eggs, once they discover how good this shampoo is they will be helping themselves and its not cheap! The Bluebeards Revenge Concentrated Shampoo has not been tested on animals they tested it on real people instead and, happily, they are all still with us and sporting squeaky clean hair!
