Keratin Volume Boost Shampoo 390ml – Strength, Shine & Visible Volume

Fine, limp, or damaged hair that needs real volume and strength. The BelleVie Keratin Volume Boost Shampoo 390ml is one of the most recommended keratin shampoos trusted by customers across the USA, UK, and Europe — hydrolyzed keratin rebuilds hair fiber integrity from root to tip, caffeine stimulates scalp circulation to support stronger growth, and rosemary oil reactivates the scalp for visible, long-lasting volume. COSMOS Natural certified by ECOCERT. Gluten-free, nut-free, vegan, and manufactured in Northern Europe to EU cosmetic safety standards.

Fuller, shinier, more resilient hair with every wash. No stripping. No heaviness. No compromise.

What It Does

• Strengthens Hair with Keratin Proteins — rebuilds hair fiber structure to reduce breakage and improve elasticity
• Delivers Visible, Long-Lasting Volume — lifts strands at the root for fuller, more body-rich hair
• Enhances Natural Shine and Smoothness — keratin seals the cuticle for a polished, salon-fresh finish
• Gentle, Moisture-Preserving Cleanse — removes buildup without stripping natural oils
• Stimulates the Scalp — caffeine and rosemary oil support circulation and stronger hair growth
• Improves Manageability — easier to detangle, style, and maintain between washes

Key Ingredients

• Hydrolyzed Keratin — the same structural protein hair is made of; penetrates the hair fiber to rebuild strength, reduce breakage, and boost volume from within; the gold standard for fine and damaged hair repair
• Caffeine — stimulates scalp microcirculation to support stronger, healthier hair growth; one of the most effective natural actives for scalp reactivation and hair loss prevention
• Rosemary Oil — clinically studied for scalp stimulation and hair growth support; comparable to minoxidil in clinical studies; boosts circulation and adds a clean, invigorating finish
• Sodium PCA — NMF humectant that maintains moisture balance during cleansing for soft, manageable hair after every wash
