I don't often have "empties" a.k.a beauty products so well-loved they're used down to the last drop in an emptied bottle. Dry shampoo is the only exception. In fact, if I were to make an estimate I'd say my hair is 50 percent dry shampoo at any given moment. I can't tell you the number of times it has saved me from looking like a mess after a sweaty workout, post-flight greasiness, or flatness the second day after a salon blowout.
As someone with really thick, long hair, I'll take any excuse to skip shampooing and save time in the morning. That means I've been on an endless hunt to find the perfect dry shampoo. What does that look like? A formula that makes you actually feel cleaner, eliminates stringy, oily strands in an instant, adds some grip for styling, and most importantly, doesn't appear white on my dark strands.
I go two to three days without washing thanks to dry shampoo. If you've got the same habit, just keep in mind that there is such a thing as using too much of it. As Dr. Dominic Burg, chief scientist and biologist for évolis professional, has told ELLE.com, "You can think of it in a similar fashion to applying a foundation or powder to your face. You wouldn't leave those products on your face for days on end. Your scalp is no different," he said. "The fine starch powders used in dry shampoo can be very clogging for the scalp, particularly follicular pores...instead, focus on the hair strand's lengths and ends. Excess powder on the hair strands should be brushed out thoroughly on a daily basis to avoid buildup."
Apple cider vinegar is known to have antimicrobial properties—and particularly help with scalp health. This formula also has naturally antiseptic ingredients like lavender and dandelion extract, so you know you're really getting clean and not a superficial dusting of product.
