What’s a co-wash A hybrid between cleanser and conditioner, our creme based co-wash uses the mildest, non-foaming cleansing ingredients, and amazing natural oils which together remove build-up and moisturise the hair. Why co-wash? Some curls find regular shampooing too drying. Curly hair that is thirsty for moisture will love this product. Gentle and moisturising enough for daily use this co-wash is the perfect cleansing solution for frizz prone curls, anyone following a "no shampoo" routine or the Curly Girl Method, or those that want to wash their hair more regularly.
