How To Use Crazy Colour Caution UV

Every 4 pack of Crazy Color Caution UV will come with its own set of instructions and guidance for use. For the best results, make sure to follow all of the information provided. As with all hair dyes, you should always perform a strand and patch test to check for allergic reactions. The dye should be applied to wet hair and left to sit for a maximum of 30 minutes.

Caution UV on Dark Hair

As a lighter and less intense shade, the yellow colour of the Caution UV shade will certainly pop more when applied to bleached and pre-lightened hair. A level of 9 or 10 is generally recommended in order for you to get the best out of this bright yellow hair dye. You can pick up a Crazy Color Bleach Kit to help you start the hair lightening process.

Crazy Color Ingredients: Aqua (Water), Cetearyl Alcohol, Ceteareth-20, Distearoylethyl Hydroxyethylmonium Methosulfate, Propylene Glycol, Ceteareth-30, Citric Acid, Formic Acid, Methylchloroisothiazolinone
