How to Make Semi-Permanent Hair Dye Last Longer

Wash Hair With Cold Water

To keep your new hair color vivid and bright, we advise that you wash your hair with cold water (as cold as is bearable). Cold water keeps the hair cuticles closed and therefore stops the color running out and fading too soon. Warm water is the enemy!

Shampoo As Little As Possible

Each time you wash your hair, the semi-permanent hair dye will lose color. We therefore suggest that you limit the number of times you wash your hair each week to keep your hair looking vibrant. However, when you come to washing your hair, we also recommend using one of our vibrant shampoo’s which are designed to maintain vibrant color. These are available in 4 vibrant shades, which means your chosen color match can be used across any shade of red, blue, pink and purple Crazy Color shades.

Use Sulphate-Free Conditioner

Make sure you use a salt and sulphate-free conditioner to keep your hair feeling healthy and hydrated. Check out our Rainbow Care Deep Conditioner which helps maintain the strength, shine, and suppleness of bleached and colored hair.

No Sunbathing

Too much direct sunlight will strip the semi-permanent hair dye from your hair and will result in fading. Do your best to protect your new color by limiting direct exposure to the sun. If you’re on holiday, keep yourself in the shade as much as possible to keep your hair color looking vivid and bright.
