When wash day rolls around, cleansers that lift only odor and greasy film just don’t cut it. With a week of buildup trapped in our hair follicles, we often require something that’s going to give our scalp a full-on revival. A shampoo with detoxifiers like apple cider vinegar and tea tree oil are great options. But for squeaky-clean tresses, we recommend a cleanser that contains our personal favorite, charcoal. No, not the sooty stuff that’s underneath the grill. We’re talking about the purer version that’s a godsend for those with dirty hair and oily skin. Activated charcoal has microfine holes that can absorb up to 200 times its weight in impurities. Here we’ve rounded up nine of the best activated charcoal shampoos just for you.
