Assuming you’ve switched up your shampoo routine, your next port of call is rethinking your conditioner, says Dobson: “A conditioner can also be an element of your routine that’s making your hair look greasy,” she says. Conditioners that boast ingredients like moisturizing shea butter, nourishing coconut oil or shine-enhancing silicones are beneficial for thicker, drier hair, but Dobson says that they can be too heavy for other hair types. “If you have finer hair, a lightweight conditioner — free from silicones — or even just using a leave-in spray post-shower, could be a better option,” says Dobson.
