This is a wonderful rinse out conditioner specially formulated for black and dark brown hair and will add shine and moisture as well as detangle and nourish your hair. Walnuts have long been used to help strengthen black and brown hair and add lustre and shine with a touch of highlight colour. It will not in any way change the colour of your hair, but after longer use, it will just enhance natural dark shades. This can also be used as a leave-in conditioner for a deeper treatment. Use after our shampoo bars or our liquid shampoos. HOW TO USE Please shake before use! Place a small amount in your hand and massage into your hair. Leave in for a minute or if you want a deeper treatment to leave in for longer. Rinse properly with water, followed by a vinegar rinse to add even more shine (small amount of vinegar diluted in warm water poured over your hair. Don't worry the smell will go!) Please keep out of the eyes! This product contains a small amount of the approved preservative optiphen. Optiphen is a formaldehyde and paraben-free preservative. Without this, the product would not be usable for more than 3 weeks.
