Hot balmy summers are amazing are amazing ,it does however speed up the fading process with your colour
Here are a few tips how to help prevent fading this summer
Do an intensive moisture treatment several days before you have your colour done .The better conditioned your hair is, the easier the colour will take and the longer it will last.
Wash your hair a couple of days prior to colour , This will allow the natural oils to distribute throughout the hair . The natural oils also help to protect your scalp from the chemicals in the dye.
After you have your hair coloured go as long as you can without shampooing. This gives your hair time to absorb the colour completely
Use uv protective shampoos and conditioning products , there is also uv protective sprays which finely coat the hair and provide a protective barrier against the suns harmful rays , in my opinion Kerastase has a fantastic sun care range
Heat also contributes to fading so use heat protective sprays , these provide a protective barrier between the hair and the heat from the styling too
