I have used Treatwell salons a number of times for har colouring and always found it just okay. However at Jeju (which I’ve now been to twice) I felt that I received a really professional service that was on a higher level than my previous experiences. The staff are diverse and very sweet with lots of experience. I felt that they really thought about me as an individual and I’ve loved the results both times. I will definitely be going back there and highly recommend them.
