If you’ve got thick or dry hair, you’ll definitely still want to use conditioner post-shampoo. But if you’ve got baby fine hair, you should actually switch the order. Philip B. recommends applying conditioner, warming hair with a blow dryer for five minutes to let it soak in, then shampooing to lift any excess product from your hair. “You’ll end up with perfectly conditioned, clean, bouncy hair — with no residue to weigh it down or make it fall flat,” he says.
