If I see my old hair dresser how should I respond?

I was using the same hairdresser for over 15years but the last 2 times she did not do a good job on my hair-cut it too short when I specified said not to and made it too dark when I said not to(she thought it would look better) then when I had to have it lightened she charged me. that whole thing ended up costing me $200! I felt like she screwed it up on purpose to have me pay double. Ok I tried someone new yesterday for I have been using her to cut my bangs(this place cuts bangs for free)she has long hair like mine and is blonde like me. she also had given me a coupon for 50% off my 1st visit. got my hair done and it looks amazing saw a few people yesterday who could nt believe how good my hair looks. she also dyed my eyebrows for free which I desperately needed(they were getting darker guess my natural color is ) i plan on using her again next time , but I sometimes run into the old person if she says who did your hair what should i say? i feel bad in a way but the last few times she did not do my hair good at all. tanks.If I see my old hair dresser how should I respond?
Be 100% honest. Tell her that you didn't like the last few cuts, colors and styles, you felt as though she was no longer listening to you, she was no longer respecting your opinions, needs or wants, and you felt you were spending too much and not getting satisfaction in return. Tell her you found someone who listens to you and works with you and you are far more satisfied with the new stylists work. You really don't owe your stylist any more than that, You paid for her service, you weren't happy, you found a better place with better service.If I see my old hair dresser how should I respond?
Don't worry about what she will think, it's your hair! Sure you will feel bad upon seeing her but you need not explain yourself, she screwed up. If the new place is giving you the result you want then build a relationship with them so that they know what you want/like and work with you--not do what they feel like doing with your hair.
