Ive used box dyes for years - Loreal excellence 7dark blonde. My hair is in a rubbish condition and I think this is due to dying it every 4 weeks to cover greys and the heat I put on it. I have invested in some straighteners which I can adjust the heat and also making sure I use a heat protector spray.
my colour goes orange quickly. Are some box dyes better than others? Is the Josh Wood one better for hair? It seems so expensive! Any suggestions?
