Slate is a metallic blue hair dye which is packed full of quartz. This shade will create steel blue hair which will shine under light. For the best results, we recommend lightening your hair to level 9 or 10 (blonde) before use.
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.
