Aveda's new Nutriplenish range is all about moisture, using organic pomegranate oil (which is rich in omega 5) to help hydrate dry strands. There are four products in the line: a shampoo and conditioner that are best for straight and wavy textures, as well as an oil and the Aveda Nutriplenish Leave-in Conditioner (£27.50), which are both rich and hydrating enough for hair types ranging from 2C to 4C.
