Here is a strange product. Strange, well. The Swedish brand Sachajuan has developed Scalp Scrub, a sugar scrub that is good to use once a week as a pre-shampoo treatment (note, it is not a shampoo) to relieve the feeling of dirt, dandruff or weighed down hair. You will notice that your hair is very loose, weightless and clean, and you will be able to space out your washes.
It is formulated with Sachajuan's classic technology, Ocean Silk. It contains climbazole (fights dandruff) and soy and shea butter oil that help retain moisture without making it greasy. Natural sucrose helps exfoliate and "unclog" the scalp surface of dandruff, oil buildup and dead skin. It sounds serious: it is, and it's also pleasant. You can have it all. To exfoliation bliss.
This video shows you how to use the products in the Scalp line.
