I've been to Paul Mitchell several times and had very good experiences. So please take this as simple feedback from a rather bad day to visit.
First: I visited on a Monday, which is when the Phase 1 students are available. This isn't a bad thing as you still have teachers on the floor. Don't let that deter you. However, just be aware of what you're walking into on Mondays and understand these students are newer and need the experience.
Second: I had the rather unusual experience of getting highlights done by my student (Kari) and a second student who volunteered to help. Now, Kari did an excellent job, but the other student is clearly not confident in doing color yet and made it abundantly clear that my long hair made it more difficult for her to do the highlights. As a customer, that's a little disappointing to hear, but I can understand she's a student who isn't aware of how to do the work and handle customers yet.
Third: My highlights were uneven. By the time my highlights were finished, the results were clear. Kari's side was mostly fine. The other student had taken too much hair, been too lazy with the blonde highlights, and caused it to bleed into the rest of my hair. I was doing a combination of highlights and lowlights. So this was frustrating because I had my hair washed and then had to have my natural color put onto the roots to cover the bleeding. That left me waiting longer because there was another wash in my future.
Fourth: Despite all the frustration with the color situation, Kari did a great job, stayed as professional as she could under the circumstances, and kept her instructors informed about the situation. I had five people, including the other student and the three teachers on site, work on my hair total. I got in at 10 am and left at 3 pm, and this is not an exaggeration.
Overall, they managed to fix my hair and cut it in the manner I requested. And that was with the help of teachers who worked hard to make it up to me. So the only real issue I take is the amount of time it took.
