How does this shampoo help hair look fuller at the roots?

The product uses Biovolume 128, rice protein and caffeine to create lift at the base of each strand while adding texture that reflects light for more visible body. Its lightweight feel avoids the flattened outcome heavier conditioners can produce.

• Biovolume 128: engineered to expand strand diameter for fuller appearance
• Rice protein: adds temporary thickness and improves hair texture
• Caffeine: invigorates the scalp for a lifted look at the root zone
• Non-greasy finish keeps hair buoyant between washes

Is the formula gentle enough for daily use?

Yes — this shampoo is formulated without sulfates, parabens and silicones, and rinses clean so you can use it frequently. The mild surfactants remove product buildup but are not overly drying, making it suitable for daily or near-daily routines for many users.

• Sulfate-free cleansing agents that reduce stripping
• Silicone-free to avoid weighing down fine strands
• Vegan and cruelty-free ingredients for ethical use
• Designed to leave a soft, non-greasy texture after rinsing

What does it smell like and how will it fit into my routine?

The scent profile is a citrus spice blend that gives a fresh, zesty lift without being overpowering. Use on wet hair: massage into the scalp, distribute through to ends, leave for about one minute and then rinse — it pairs well with lightweight conditioners or a volumizing styling spray.

• Citrus spice scent: bright and warm, not cloying
• One-minute leave-in time for active ingredients to work
• Compatible with styling products for added lift
• Works as a daily shampoo for many hair types, particularly fine hair

What should I expect in terms of ingredients and safety?

The formula highlights biotin, Biovolume 128 and rice protein while avoiding common heavy or controversial additives. It is paraben-free, sulfate-free, silicone-free, vegan and cruelty-free, making it a cleaner option for those who watch ingredient lists.

• Biotin included to support strand strength and resilience
• Free from parabens, sulfates and silicones
• Vegan formulation and cruelty-free testing practices
• Gentle enough for routine use, yet effective at removing buildup
