I went for a colour correction recently and felt the entire experience was mediocre but not altogether unpleasant.
I am disappointed that the lady I spoke to on the phone with who scheduled my appointment didn't mention that the more out-there hair colours (pink, blue, green, etc.) were not dyes but rather stains. As such, I was disappointed with the relative low-intensity of the end result and redyed my hair with Splat a day later.
The salon is clean, well-decorated and easy enough to find. As a plus, the owner interacts with all of his employees in a respectful and friendly manner.
For the lack of expertise and quality of products, I was expecting a lower price than I paid ($200 with a 15% tip for a colour correction and bang trim).
