Over-washing with stripping shampoos and under-washing with product buildup both damage the same thing: the scalp microbiome — the diverse ecosystem of beneficial microbes that regulates sebum, maintains pH balance, and creates the conditions for consistent hair growth. This physician-formulated scalp shampoo is one of the few certified microbiome-friendly cleansers available, meaning it's been independently verified to preserve and strengthen the diversity of beneficial scalp microbes with every wash, rather than disrupting them.Alpha-Glucan Oligosaccharide (prebiotic) feeds and strengthens the scalp microbiome barrier, improving its ability to defend against environmental disruptors. Australian Wild Berries (Syzygium Luehmannii and Tasmannia Lanceolata) deliver antioxidants to protect the scalp from oxidative stress and pollution. Vegan Protein (Hydrolyzed Quinoa) replenishes nutrients and moisture to the scalp while gently cleansing. Biosurfactant (Caprylyl/Capryl Glucoside) deeply cleanses and lathers without stripping the scalp's natural oils. Glycolipids and Glycerin hydrate the scalp and maintain moisture balance post-cleanse. The formula is pH-optimized to maintain the scalp's natural acid mantle for a balanced, healthy growth environment.Clinical results: 100% of users had a clinically effective reduction in sebum immediately after use; 100% had immediate improvement in dry, flaky scalp. Visibly improves hair volume, strength, and texture in as little as 2 weeks. Color-safe, extension-safe, sensitive-scalp tested. Free of hormones, drugs, parabens, phthalates, silicones, sulfates, and synthetic fragrance. Apply to scalp, massage for 2 minutes, rinse. Gentle enough for daily use.
