If you're a natural, your hair and scalp are both very likely to accumulate lots of buildup, for which Taylor recommends using Keira Ashley Hair + Scalp Cleanser ($45). "This cleansing oil clarifies and moisturises all in one," she said. "It's got multiple benefits all in one: it reduces scalp irritation, dry scalp, psoriasis; it stimulates hair growth and prevents hair loss, and it strengthens and reduces breakage."
