Bleach London gentle, semi-permanent Super Cool Colours are for all hair types!

White Heat works best on hair that's been bleached and toned.

The best way to check the colour your hair will go after using this dye is with a strand test.

You must also do a skin sensitivity test before using it.

One bottle is suitable for short hair or colouring freshly bleached and toned roots.

For shoulder length hair you'll need two bottles.

For long hair that's below your shoulders, you'll need three to four bottles. If your hair is very thick we recommend adding an extra bottle.

1: PREP Ensure hair is clean, towel dried and detangled
