If he's currently got a lot of hair, especially thick hair that will take a long time to dry, you can always blow-dry it with your favourite hot tool and the Verb Blow Dry Brush ($18). Or, have him wrap his head in the Aquis 03 Prime Rapid-Dry Hair Turban ($30) first (since most clippers work best on dry hair). This lightweight towel doesn't grab hair cuticles like normal bath towels, and can reduce drying time by up to 50 percent so you can get started sooner.
