For black and dark coloured coats only - do not use on multi coloured coats. Very concentrated - do not use neat, always dilute. Wear gloves to protect your hands from staining.
For first time use, use one capful of Black Magic mixed with a dilution of your usual shampoo. Works by leaving tiny particles of pigment behind, which are trapped inside the hair shaft. Even when you're used to using it, the concentration means you can dilute at approx 1:8 - making it very economical to use. For best results, use with Sealer Magic Conditioner.
