The night before an event, I mix organic coconut, argan and sesame oil (with essential oils) in a glass container which I immerse in a separate container of hot water. I work this through my hair with my fingers and sleep with it overnight. The next morning I wash it out with organic shampoo (free of sulphates, parabens and sodium benzoate) and lukewarm water. I let my hair air-dray outside in order to harness the vitamin D properties of the sun. - ROELIEN S

Since I have a wavy-curly texture — my background is Cuban — and my ends tend to get quite dry whenever the seasons change, on the eve of summer I make a hair mask using 1/2 ripe avocado (mashed), and I add a little bit of Josie’s argan oil and a few drops of lavender, just to make it extra fragrant. I apply a little bit to my roots and tips, sealing the moisture with a shower cap. After 20 minutes, I rinse off, let air dry and boom: gleaming, soft hair. My grandmother used to do everything with avocados when she lived in Cuba, from making delicious avocado-mango custard desserts to using them as natural conditioners and moisturizers. It’s sustaining, great for your skin, and delicious. - NG
