Hello Jane
Thank you so much for your review; I'm sorry to hear of your poor experience.
You mentioned the dye flaking off, which doesn't sound right; the dye should stay wet and covered on your hair while it processes, and left on for a minimum of 90 minutes.
If the dye isn't kept covered on the hair it won't form a 'bond', and so you likely won't achieve a good colour, unfortunately.
I am sorry to hear you didn't achieve a good resuit; please do get in touch with us by email if you'd like to try again and I can give more information on best practise so you can get the colour you're hoping for.
With Kindest Regards
Rebecca
