I was dying my hair every two months for last 5 years at the same place in my city, so I was pretty nervous about my first experience of that sort here. First, it is better to choose a salon that has an English version of the website – it is one of the signs from which you can understand that there are English-speaking masters there. In general, it is better to make an appointment, specifying your language preferences, especially if your demands are more than “just cut 1 cm off”. There is also an opportunity of asking some advice for good salon from locals, but prepare to use all your Czech vocabulary. Apart from that, the whole process was quite professional, even though the master was a junior.
