Very convenient that I could book on the day, one of the few salons offering 'bring your own hair dye' service and for only 10 pounds. And no extra charges at the salon. This is especially useful if, like in my case, you have to use a more natural hair dye than what is being offered in salons. Perhaps it could cost an extra 5 pounds and they could dry your hair too as it is not nice to leave with your hair wet. But otherwise, for what it is, I am very pleased with the treatment, therapist and price and will certainly be going back.
