Why a Colour Shampoo Is More Convenient

Traditional hair dye requires mixing components, strict timing, gloves, a brush, carries the risk of skin staining and fills the room with ammonia fumes. Biowoman Bio Nutrients Color Shampoo works differently: squeeze the sachet, apply to dry or slightly damp hair like a regular shampoo, lather from roots to tips, wait 10–15 minutes — and rinse. Result: grey covered, hair soft and shiny. The 30 ml sachet is ideal for travel and for trying the product for the first time.

Key Active Ingredients

• French Pine Bark Extract — powerful antioxidant (oligomeric proanthocyanidins). Balances and strengthens hair and scalp, reduces hair fall, protects against oxidative stress
• Corn Sugar — deep hydration ×2. Replenishes moisture loss within the hair structure, improves elasticity
