The problem with some hair serums is that they can be so greasy or heavy, you looked as if you've been hanging out near a FryDaddy in the rain forest. But not with with L'Oréal Professionnel's new Mythic Oil ($29). The fast-working hair product, made from avocado and grape seed oil, doesn't just protect and nourish the hair, but also gives one truly amazing blow-dry.
A little goes a long way, and hair is left smooth and shiny but not limp or slick. You can even use a small amount on dry hair to tame frizz, or add a bit to a styling product to add softness. In essence, it's a great little multitasker that will make your morning blow-dry time blow right on by.
