Most conditioners coat the hair shaft with silicones that create the appearance of smoothness while clogging the scalp and microbiome over time. This physician-formulated, silicone-free conditioner uses a multi-layer protection system of natural actives to genuinely strengthen the hair shaft from within — improving elasticity, reducing breakage, and defending against thermal and mechanical damage without compromising scalp health.

Hydrolyzed Quinoa (Vegan Protein) penetrates the hair cortex to fill structural gaps in the hair fiber, visibly improving strength, elasticity, and shine. Australian Wild Berries (Syzygium Luehmannii and Tasmannia Lanceolata) provide antioxidant protection against environmental damage and UV-induced fiber degradation. Alpha-Glucan Oligosaccharide (prebiotic) maintains the scalp microbiome health when conditioner contacts the scalp during rinsing. Panthenol (Pro-Vitamin B5) coats and smooths the cuticle layer, reducing friction, frizz, and mechanical breakage. Glycerin and Diisopropyl Adipate provide lightweight, non-greasy moisturization to dry or brittle strands. Guar Hydroxypropyltrimonium Chloride detangles without buildup.

Certified microbiome-friendly. Clinically shown to improve hair strength, softness, and manageability. Color-safe, extension-safe, sensitive-scalp tested. Free of hormones, drugs, parabens, phthalates, silicones, sulfates, and synthetic fragrance. Pair with the Root Purifier Shampoo for best results. Apply after shampooing, leave 2–3 minutes, rinse.
