This dark blue hair dye will have everybody shaking their tail feathers! This luxuriously pigmented shade has a slight green undertone and is always a customer favorite. To get beautiful dark blue hair, we suggest lightening to level 9 or 10 (blonde) before use. It is also suitable for level 8 (light brown) hair, however, results will only be tonal.

To achieve exotic, vibrant semi-permanent results, hair must be porous or processed before application. For best results, use on pre-lightened hair. Use in conjunction with the Crazy Color Rainbow Shampoo and Rainbow Deep Conditioner to keep your hair looking healthy and ex tend the life of your colour.

Light, silver and white colours are advised to use the Crazy Color Ultra Violet No Yellow Shampoo to remove unwanted yellow and brass tones that develop in these shades over time.

The lighter your hair, the longer your wear. Formulated to last 8-12 washes with no colour fade. Requires no ammonia or alcohol and is a gentle alternative to permanent colouring. A ready-to-use formula that requires no peroxide (gloves required). Simply apply to treated hair for vibrant and deep shades.
