Fine, limp, or damaged hair that needs real volume and strength. The BelleVie Keratin Volume Boost Shampoo 390ml is one of the best keratin shampoos for fine hair in the 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. Gourmand aroma with fresh peppermint and rosemary on a vanilla, tonka bean, and sandalwood background. COSMOS Natural certified by ECOCERT. Gluten-free, nut-free, vegan, and EU-made.

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

Who It’s For

• Fine, limp, or flat hair seeking the best volumizing keratin shampoo UK
• Weak, brittle, or breakage-prone hair that needs structural keratin repair
• Chemically treated, colour-treated, or heat-styled hair
• Those seeking a scalp-stimulating shampoo with caffeine and rosemary oil for hair growth
• All hair types — suitable for daily use across the UK and Europe

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; 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

Frequently Asked Questions

Is this the best keratin shampoo for fine hair in the UK?

The BelleVie Keratin Volume Boost Shampoo combines hydrolyzed keratin (structure + volume), caffeine (scalp stimulation), rosemary oil (hair growth support), and Sodium PCA (NMF moisture) — a COSMOS Natural certified thickening shampoo for fine, flat, and damaged hair. Popular across the UK and Europe as a volumizing keratin shampoo for thin hair.

Does caffeine in shampoo actually help with hair growth?

Research suggests that caffeine applied topically to the scalp stimulates hair follicles and supports the hair growth cycle. Combined with rosemary oil — one of the most studied botanicals for scalp health and hair growth — this shampoo provides meaningful scalp stimulation with every wash.

Is this suitable for fine or thin hair?

Yes — specifically formulated to add volume and body to fine, limp, or flat hair. Keratin proteins strengthen strands from within while volume-enhancing agents lift at the root — without weighing hair down or leaving residue.

Does keratin shampoo work on colour-treated hair?

Yes — hydrolyzed keratin is safe for colour-treated, highlighted, and chemically processed hair. It helps repair damage caused by colouring and heat styling while extending colour vibrancy by smoothing the hair cuticle.

Is BelleVie vegan and cruelty-free?

Yes — all BelleVie products are 100% vegan and cruelty-free, COSMOS Natural certified by ECOCERT Greenlife, and formulated and manufactured in the EU to the highest cosmetic safety standards.
