Ouidad's VitalCurl™+ Leave-In Styling Serum is a lightweight, multi-purpose serum that hydrates the scalp and hair while also enhancing curl definition. Use it as a leave-in to help prime curls before styling, on its own as a lightweight air-dry styler, or as a targeted treatment to help restore strands overnight. Infused with good-for-curl ingredients like niacinamide, biotin, peptides, and probiotics, this styling serum provides weightless moisture while also helping to strengthen curls and balance the scalp. The brand's signature Botanical Omega 3-6-9 Complex (featuring chia seed, Japanese camellia, and sunflower oils) targets dry areas to help fortify hair’s natural lipid barrier, which retains your hair’s moisture, elasticity, and bounce.

“Proper hydration and a balanced scalp are key to creating consistently defined, healthy-looking curls. This leave-in serum is formulated with ingredients like niacinamide, peptides, and probiotics that are known to help retain moisture and promote a healthy scalp, so it's working to nourish your strands as you style."
