Yung recommended I try the The Dove Scalp+ Hair Therapy Scalp Serum. It’s not a hair oil — so, it’s not comparable to say, the viral rosemary oil. Instead, it’s a water-based formula that looks, feels, and functions like a skincare serum you’d use on your face. “It really is a skincare formula,” offers Dove’s consultant dermatologist Mona Gohara, MD. Not only does the water-based formula make it absorb into the scalp instantly, its key ingredients — glycerin, niacinamide, and zinc — are hugely beneficial for the scalp, especially a dry scalp, like mine.
