Even though hair oil is expected to be a little bit, well, oily, here is a way to use it without getting limp and greasy strands. Enter: SoftSheen Carson's Optimum Alma Legend Billion Hair Potion ($10). More of a serum than an oil, this product melts into the hair and scalp, leaving no residue behind. Plus, the eyedropper applicator ensures that you get the product just where you need it and not all over your hands (and face). But the standout ingredient in this elixir is amla oil from India, a key component in ayurvedic rituals to remedy hair loss. To make the amla extract, the fruit is soaked in sesame and coconut oils, which means, in turn, you're getting the benefits of vitamin C, antioxidants, and proteins. Perhaps it's time your hair booked an ayurvedic spa experience.
