6. Pre-Treat

All lightening treatments will – by definition – cause a fair amount of dehydration and weakening in your hair.

In order to minimise the damage, make sure your locks are in great condition before you get on with the business of bleaching;

apply a powerful strengthening conditioner for a few days before you plan to do the dying, and make sure that you take proper care of your locks once they have been successfully lightening as well.
