I got a haircut and color at Vain a few years ago, at the advice of a co-worker. I was really disappointed, especially after reading all the hype this salon gets.
My partial-foil ended up looking way more like a single color all over. It definitely wasn't the look I was going for, and I felt I was very clear. The haircut was also not what I had requested and I was very taken aback when I requested bangs and the stylist told me no, stating that it wouldn't flatter my face. I have had bangs many times in the past and believe it's my choice what I do with my hair.
My experience wasn't worth the money, but it was a few years ago and I have no idea whether or not that stylist is even employed there any longer.
