Four lessons dive into the ins and outs of using various product types to treat your hair and scalp, with tried and tested formulations enriched by evidence-based essential oil blends. You can follow our formulas, but we will also teach you to customize your creations!
We start with Lise Andersen’s lesson where she will discusses ingredients that are beneficial to your hair and walks you through how to make hair serums, pre-shampoo treatments, solid shampoos and clay masks, ready for you to add your essential oils of choice.
Robert Tisserand spends the next three lessons going through three common areas of hair complaints – dry and damaged hair, oily hair and dandruff, and hair loss. He dives into the available research on essential oils and fatty oils that are useful for each of these areas and suggests blends that you can plug into your base formulations.
At the end of the course you will have the knowledge not only to make, but to customize your haircare, incorporating essential oils for great results – and divine scents!
