There are only so many synonyms to describe how bright this colour is, but I think “luminous” is most appropriate. Caution UV is really easy to apply, covering effortlessly to give bright, even coverage. It is very, very bright in daylight, but under UV it is exceptionally bright and glows a vivid highlighter pen yellow.

Caution UV is an excellent mixer and can be combined with other shades to make beautiful, bright colours. It also dilutes well to make a very vivid pastel.

Apply directly to damp or dry hair using a tint brush for best results. Wear protective gloves to avoid temporary staining to skin and nails. Massage the product into your hair and allow to process for at least 15 minutes. Cover with a cap to avoid drying out. Rinse thoroughly in warm water.

  • Precautions

    Crazy Colour should be used exactly as supplied without the addition of any other substance - it does not require a developer. For the brightest results the hair must be bleached to pale blond. Platinum and Silver will only work on very light hair.

    Do not use Crazy Colour on hair containing more than 10% white. Do not add peroxide. Do not mix with permanent colourants.

    Colours may cause permanent staining on textiles and porous surfaces. Staining to baths, sinks and showers can be removed with household bleach. Always check manufacturer's instructions.
