Marula oil is made from the fruit of the African marula tree. The oil is non-comedogenic and won't clog pores. Marula is full of essential fatty acids that hydrate both the skin AND hair - which is why you'll be seeing everywhere. I love Paul Mitchell Marula line. It's cruelty-free and it smells amazing!
It's a similar story for Kalahari Melon Seed Oil. African, lots of essential fatty acids, non-comedogenic, can be used on both skin and hair. Plus, it's nourishing in antioxidants, similar to Evening Primrose Oil. Finally, it's a super non-greasy option, making it a great choice for oil cleansing, hair masks and for being a carrier oil for those ever-popular essential oils. Kalahari is esoteric now but due to it's ultra-hydrating properties, it won't be for long.
You will be seeing more and more of Castor Seed Oil. Now, I just bought some yesterday and the cashier said, You must have some bad kids! Being childless, I looked around. Then I realized he was referring to the olden days, where parents would make naughty kids drink castor oil as punishment for bad behavior. But Castor oil, you see, has made a resurgence because - wait for it - it makes hair grow!! At least, anecdotally. Castor oil contains called ricinoleic acid, which stimulates circulation of the hair follicle. Beauty gurus swear by applying a thin layer of castor oil to the brow and lash line. On the scalp, at the very least, castor oil is said to be anti-dandruff. It has very powerful levels of antioxidants, unsaturated fatty acids and anti-inflammatory properties that even Cleopatra swore by. Castor oil of the Jamaican Black Castor Oil variety is especially popular.
Lastly, you will be seeing Orchid extract featured on hair and skin products. Now, as far as flowers go, you've seen way more of Lavender and Rose extracts for their soothing properties. However, Orchid extract is a great skin food because it contains calcium, magnesium and zinc. You will also see orchid extract pop up in color-protecting shampoos such as Nexxus.
