Plantur 39 Colour Brown is a great product to use between colour or just to promote your own hair colour. I was very impressed to see an immidiate diffrence in colour and texture after the first wash. Best of all is that Plantur 39 does not leave any colour residue on your hands. After wash number 5 there was practically no diffrence between my roots and the rest of my hair. Very glad that I could be a part of this trail, will definitely recommend the product. Love love love this product!!
