Just like you'd exfoliate your skin or get extractions to clean clogged pores, you should begin by clarifying your scalp. Buildup from hair spray, dry shampoo, and other products you might have accrued over the week need to be removed! If your hair is naturally on the oily side, this will help tone that down, too. Try Fekkai's Apple Cider Clarifying Shampoo ($20) or some good ol' fashioned apple cider vinegar ($15).
"Split your clarifying shampoo between your hands, then apply directly to the scalp," said Frédéric Fekkai stylist Jerome Gaultier. And unlike a treatment you'd leave on for 10 to 20 minutes, being quick is key. "Rinse [the clarifying shampoo] quickly, or you risk drying out the ends of your hair," said Gaultier. He also suggests leaving clarifying products on the scalp for no more than a minute.
