Haircut in Bangkok

Could someone please recommend a higher end hair salon in Bangkok? I just went to a very well reviewed one, and they had me wait with no explanation. I left after half an hour. I was also observing other haircuts as I was waiting, and I could see that at least one of the cutters cut unevenly. I just left. I understand that the culture and standards may be different from where I come from, so I'm looking for something that will be similar to what I would get in the US. I don't mind paying US prices for a good result. Thank you!

Edit: I found a western style Aveda salon at Em quarter. They did a great job cutting my hair. I recommend them. Women's haircut, no color. 1400 bht
