I've not seen this before but today saw an advert via Facebook, with introductory offer, obvs.
I oscillate between getting my hair coloured by the hairdresser, and then toying with the odd self-dye from Boots. I can't really tell much difference in quality, if truth be told, although the shade is different if I do it myself of course.
Just wondered if anyone else has bought from e-Salon, after their questionnaire plus photo request?
