Some of my friends gave me a voucher in this hairdresser as a birthday present: very nice local and cut but I asked for a lightening at the tips which turned out to be very disappointing because not very visible. To resolve a misunderstanding about the total price, I have been charged a part of the money on the card used for the "vouchers", I return to use this voucher, I apologize to the staff for the misunderstanding a few days earlier but I do not receive an answer and I also come treated very badly.
The prices are not written on the site, in fact they are very, too high.
I strongly advise against it, I will never go back.
