Black Rock Shampoo is designed to help correct the signs of premature hair ageing by accurately darkening the lighter grey strands WITHOUT DYE. Utilizing exceptional levels of Black* Pigment, the effect is amazing, darkening not dying the greys to a deeper, richer, younger tone. Years of premature ageing can be wiped away in an instant application that will last up to 3 days, and will slowly darken with continual use. Black Rock Shampoo is exceptionally concentrated, so only a little is needed each application. For best results, wearing a protective glove, apply the neat shampoo to the grey areas of hair that you wish to target whilst the hair is DRY. Leave for a minute or two, then apply warm water, and wash hair as normal. Rinse out. Use gloves to apply. Avoid applying neat to visible skin such as ears, forehead and neck. If pigment transference occurs in unwanted areas, wash immediately. *we refer to our colour blend as “black"
