Each Neutrevo series is built around a single hero ingredient at clinically meaningful concentrations. No filler claims, no marketing-only actives. Here is what each one actually does.
For Dry & Damaged Hair
Hyaluronic acid is a humectant our body produces naturally — it binds up to 1,000× its weight in water. In hair, that means it pulls moisture into the cuticle layer and locks it there, where dryness and styling damage have stripped it away. We use a low-molecular-weight HA that actually penetrates the hair shaft, paired with panthenol and silk amino acids for a smoother slip.

Keratin is the structural protein that builds 90% of your hair. Heat tools, color, and bleach break it down, leaving strands hollow and porous. Our hydrolyzed keratin (low molecular weight, plant-derived) slips into damaged sites and rebuilds — paired with argan oil to seal the result.

Aged black garlic is fresh garlic fermented for 30+ days under controlled humidity. The process converts allicin into S-allyl cysteine — a stable, potent antioxidant that calms scalp inflammation and helps regulate sebum without stripping. No garlic smell. No greasy residue. Just a lighter, calmer scalp.

Biotin is a B vitamin essential to the keratin synthesis pathway. Topical biotin will not regrow hair the way medications do, but it visibly reduces breakage and improves the feel of thinning hair. We pair it with collagen for cortex strength and scalp-stimulating saw palmetto and rosemary extracts.

Cold-pressed argan oil is rich in vitamin E and oleic acid — it forms a flexible film around the cuticle that slows water loss and protects color from oxidation. Unrefined shea butter adds rich emollients without weighing strands down. Together they extend color vibrancy by up to 30% in salon studies.
