Ingredients

The actives, explained.

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.

SIGNATURENo.01PROFESSIONAL

Hyaluronic Acid

For Dry & Damaged Hair

Deep hydration, restored.

Hyaluronic acid is a humectant our body produces naturally — it binds up to 1,000× its weight in water. In hair, that means it draws moisture to the cuticle and holds it there in a weightless, breathable film, where dryness and styling damage have stripped it away. We use a mid-weight HA that hydrates without coating or weighing hair down, paired with panthenol for a smoother slip.

Keratin

For Damaged Hair

Protein, returned.

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) slips into damaged sites and rebuilds — supported by wheat and rice proteins and sealed with nourishing plant oils.

Black Garlic

For Oily Scalp

Balance, fermented.

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

For Anti Hair Loss

Roots, reinforced.

Biotin is a B vitamin essential to the keratin synthesis pathway. Topical biotin will not regrow hair the way medications do — but a formula built around it visibly reduces breakage and improves the feel of thinning hair. We pair it with a dedicated strengthening complex and nourishing plant oils — jojoba, castor and sweet almond — through the ritual.

Shea & Argan

For Color-Treated Hair

Color, sealed.

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. Shea butter adds rich emollients without weighing strands down. Together they help color stay vibrant longer between washes.
