Mary Beth and Emilee have both cut and styled both mine and my child's long hair over a period of several years. It's hard for me to find someone who is consistently really good with layers and with my daughter's hair that is thin, cowlicky, and grows unevenly. All the hair cuts we've gotten here have been amazing. The cuts also grow out really well. I don't think you could really go wrong with any stylist at Salon Faith. Faith makes sure that her employees are well trained and does continuing education with them on, I believe, a weekly basis. They are at the top of their game.
Side note- the Eufora products are great! If you spend a lot of time in a chlorinated pool and/or don't have the benefit of a water softener to help you cope with the super hard Scottsdale tap water, the nourish urgent repair shampoo (Eufora shampoo in the blue bottle) is going to be your hair's best friend. It strips all the minerals and chlorine out of my hair. What's left? Shine and body! It's expensive but worth it- plus a little goes a long way.
