Quality of life of the color in the hair, luminosity and brilliance are in the Poly Live XXL Colors really fantastic, although you also have to re-dyeing and after 4 weeks from the 5-6 weeks, the intensity of the color loses something, but it lasts much longer than other hair color, what does it matter that this product is an XXL Coloration, ie egentlich level 4 in the hair color (1 = washable, 2 = washable partly, 3 = must grow out) because a XXL Coloration can not bleach it if one wants to have lighter hair, since anchor the pigments to the core of the hair.
In "Cosmic Blue", the result is more black than blue, as blue as on the packaging does not affect it, it has a more bluish. But this seems much more intense than normal black black colorants, which simply looks super good and who as a black lover once had this kind of black, knows what I'm talking about;)
Regarding compatibility for skin and hair, it is as with all other colorants, there are no special features. The price is within the normal trade between 4 and 5 which is very good value for the performance of this product!
