Keratin Volume Boost Conditioner, 390ml

Thicken, Strengthen & Reactivate — Keratin Volume Boost Conditioner 390ml by Vixxar

Fine, flat hair that lacks volume and glow needs more than a standard conditioner — it needs a targeted, lightweight formula that strengthens the hair's internal structure, reactivates the scalp, and delivers genuine lift from root to tip without weighing strands down. The Vixxar Keratin Volume Boost Conditioner 390ml is a COSMOS Natural certified, plant-powered conditioner formulated with Rosemary Oil, Keratin, Vitamin E, Caffeine, and Sodium PCA — it thickens, reactivates the scalp, and adds extra volume with every wash. No heavy silicones, no residue, no buildup. With a gourmand aroma with fresh and aromatic notes of peppermint and rosemary on a vanilla sweet, tonka bean powdery, and sandalwood background.

Unlike conventional conditioners loaded with heavy silicones that coat the hair and flatten volume, Vixxar's Keratin Volume Boost Conditioner uses a clean, botanical formula that strengthens from within — ideal for fine, flat, and colour-treated hair, gentle enough for daily use on all hair types. Whether you're searching for the best keratin conditioner for fine hair, the best volumising conditioner for flat hair, the best COSMOS certified conditioner for volume, the best caffeine and rosemary conditioner for scalp vitality, the best thickening conditioner USA, or the best natural conditioner for extra volume — Vixxar delivers clean beauty results.

Frequently Asked Questions

What is the best keratin conditioner for fine and flat hair?

The Vixxar Keratin Volume Boost Conditioner 390ml is one of the best keratin conditioners for fine and flat hair — COSMOS Natural certified, formulated with Keratin, Rosemary Oil, Caffeine, Vitamin E, and Sodium PCA to thicken, reactivate the scalp, and add extra volume without heaviness. Gluten-free, silicone-free, and safe for daily use. Fast shipping from our USA warehouse.

How does Keratin help with volume and thickening?

Hydrolyzed Keratin penetrates the hair shaft to reinforce the internal protein structure — reducing breakage, improving strength, and supporting long-term fullness and thickening with consistent use. Results improve over 4 to 6 weeks of regular use.

Why does this conditioner contain Caffeine and Rosemary Oil?

Caffeine and Rosemary Oil both stimulate scalp microcirculation — reactivating the scalp and supporting hair density and vitality. Together they create a more active scalp environment that supports healthier-looking, more voluminous hair over time.

Will this conditioner weigh my hair down?

No — the lightweight, silicone-free formula is specifically designed to add volume without weighing strands down. Apply to mid-lengths and ends only, avoiding the roots, to maximise lift and volume at the root.

Can I use this conditioner every day?

Yes — the clean, plant-based formulation is gentle enough for daily use on all hair types. The absence of heavy silicones and synthetic polymers means no buildup with frequent washing.

Is this safe for colour-treated hair?

Yes — the botanical actives and Vitamin E antioxidant formula support colour protection and overall strand health. The sulfate-free approach will not accelerate colour fade.

Should I use this with the Keratin Volume Boost Shampoo?

Yes — for best results, use the Vixxar Keratin Volume Boost Shampoo and Conditioner as a matched system. Both are formulated with the same Keratin, Caffeine, and Rosemary Oil complex for compounding volume and thickening benefits.
