I've been to Ioanna's multiple times and she has always been an absolute pro. She will give you what you are asking for (considering what you won't won't ruin your hair) and she is happy to make tweaks if needed. She always offers a drink and the vibe there is very welcoming and cool. Asma has also been so lovely and gentle with washing and blowdry.
The results are stunning and by far the best hair colour and cut I've had in a long time.
