This is our brightest blue hair dye and it will certainly get hearts racing! This primary-color works perfectly as a mixer with other shades to achieve a creative tone of your choice. However, it also works well straight from the bottle for perfect bright blue hair. For optimal results, we recommend lightening your hair to level 9 or 10 (blonde) before use. It is also suitable for level 8 (light brown) hair, however, results will 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.
