If you suffer from an itchy scalp or dandruff and don't want to load your hair up with chemicals, Sachajuan's Scalp Shampoo is a brilliant alternative to commercial anti-dandruff brands. The stars of the show are a double act of anti-fungal riroctone olamine and climbazole which, according to the Australasian College of Dermatologists, are less toxic than regular flake-fighting ingredients. The addition of rosemary oil, menthol, salicyclic acid and ginger extracts then combine to soothe and nourish irritated, scale-prone scalps.
