There's good dry shampoo and then there's not-so-good dry shampoo. Klorane's Dry Shampoo With Nettle ($18) falls into the former. A cult classic, this spray-on is especially formulated for those with oily hair types. It's also great for those with bangs and short hair (yours truly) to keep strands looking fresher longer. Nettle works to regulate sebum production, while corn and rice starch take away that greasy, weighed-down feeling. Just spray on roots and allow it to sit for about two minutes before brushing it out. This will allow the ingredients to do their thing and prevent that telltale white-powder residue from forming. But best of all, this dry shampoo barely has a scent. This means no more gagging on overly perfumed product — or a cloud of product debris.
