I applied Colour 9 Cool to my medium brown hair and got a beautiful, cool tone with a smooth finish. The hair feels softer and shinier after the treatment. The colour lasted well through two washes.

The cool finish is very natural and not too intense. My hair looks healthier after using this shade. It’s easy to apply and the conditioning helps reduce frizz.
