It's a wonderful, friendly vibe. The employees know what they're doing. I'm a very picky customer but I can just relax and rely on their expertise. The best bit? They always remember your hair history and hair goals.
I have henna in my hair and wanted to colour it. However, Ahmet recommended testing first. When he wasn't sure if it was safe (despite no reaction), he proceded with caution instead of only caring about the money.
Highly recommend.
