A healthy scalp is the foundation of healthy hair — but most leave-on scalp treatments either over-hydrate (weighing hair down) or use harsh actives that disrupt the scalp microbiome. This physician-formulated 2oz scalp essence strikes the precise balance: a lightweight, leave-on treatment that hydrates, soothes, and rebalances the scalp microbiome without residue, buildup, or interference with styling.Alpha-Glucan Oligosaccharide (prebiotic) feeds beneficial scalp bacteria to strengthen the microbiome barrier and improve its resilience against environmental stressors. Australian Wild Berries (Syzygium Luehmannii and Tasmannia Lanceolata) deliver concentrated antioxidants to protect the scalp from pollution and oxidative damage that disrupts the hair growth cycle. Hyaluronic Acid provides lightweight, non-greasy scalp hydration to maintain moisture balance between washes. Panthenol (Pro-Vitamin B5) soothes and strengthens the scalp surface. Glycerin and Glycolipids work together to maintain the scalp's natural moisture barrier post-treatment.Certified microbiome-friendly — independently verified to preserve beneficial scalp microbe diversity. Designed to be used between washes to maintain the clean scalp environment established by regular shampooing. Lightweight enough for daily application on fine or oily hair without buildup. Color-safe, extension-safe. Free of parabens, phthalates, silicones, sulfates, synthetic fragrance, and hormones. Apply a few drops to the scalp and massage in. Do not rinse. Available at Beauty Riche with same-day shipping.
