Bbcos Keratin Color Hair Dye in shade 20 Darkest Brown is a professional hair coloring product for a permanent color change. This 100 ml formulation combines advanced keratin technology with intense pigmentation for deep, long-lasting color results while maintaining hair structure.

The creamy consistency ensures even application and precise color distribution throughout the hair. Each application provides consistent, wash-resistant color that lasts through multiple washes while preserving the natural shine and texture of the hair. The formulation is ammonia-free, minimizing irritation and unpleasant odors during application. For optimal results, perform a strand test 48 hours before full application to confirm color compatibility and check for possible allergic reactions. The product requires mixing with the appropriate developer according to the manufacturer's instructions. Store in a cool, dry place away from direct sunlight and keep out of reach of children. Suitable for most hair types when applied correctly by professional colorists.
