The Bionike Shine On Hair Colouring Treatment in Black (Shade 1) is a complete ammonia-free, at-home hair colouring kit that delivers rich, even colour with exceptional shine — without the harsh chemicals that cause scalp irritation and hair damage over time. Developed by BioNike with sensitive skin in mind, it's nickel-tested and safe for scalps that react to conventional hair dyes.

• Ammonia-free formula colours hair gently without the harsh fumes of traditional dyes
• Delivers deep, even Black coverage with brilliant, long-lasting shine
• Nickel-tested and dermatologically approved — safe for sensitive scalps
• Conditions hair during colouring for a noticeably softer, healthier feel after treatment
