I am super happy with JeJu and have been going here for two years.
Only at my last session I didn't have the same stylist and the color didn't turn out as I usually have it. Other than that, its a very friendly place with a nice atmosphere!
I had a haircut by Elena who is very good and very detailed. I like the look and for that I would come back again. However, the shampoo (which was done by another colleague) was quite basic and if you are expecting a Japanese shampoo with a bit of massage then don't go for this one. I did expect that so it was a disappointment for me.
