I would give them zero stars if possible. The short version is that Aveda Institute Phoenix's Cosmetology Team Lead, Aveda Certified Educator,  self-proclaimed Color Specialist, and the 2014 Inspire Greatness Champion, ANGIE PERINO NELSON, did not follow verbal or written instructions that I provided her. (I said and wrote \"apply color to new growth only.\" She put color 5\" down my head. I said I wanted to go 1 to 2 shades lighter than my standard Aveda formula I have used for 6 years: 30 vol 60 grams of Deep 10-N @ 40 mins. This provided me with Golden Honey Blond. The sun provided me with multi-dimensionality and sun-kissed streaks. Parts of my hair looked like spun gold and others were like pale blonde sunny streaks. Because I have worn my hair the SAME way in all my outdoor jobs, the outer shell of my hair was very light. She formulated 40 vol 60 grams of Deep 12-N @ 45 mins in a shower cap.  \n\nMy crown turned Polar Bear White. When I became upset, she said, and I quote, \"Sometimes this happens. Blondes are hard.\" Then she said she'd fix it. So she formulated this toner: 40g 0-N + 40g of 10-N + 1g of Light Yellow + 40mL of CTA. Unfortunately, she toned all 3 feet of my hair--not just the Polar Bear White part. The result was my crown became a monochromatic Electric Butter Yellow and the rest of my multidimensional golden honey blond hair became shades of Straw Yellow and included some Pumpkin Orange. It wasn't in shades of blond but in shades of YELLOW as in Crayola Crayon shades of yellow. Angie Perino Nelso wouldn't face me at this point and was conveniently absent for the final review of my hair, and a senior manager told me to come back for a free color correction. \n\nI learned after the fact from other Aveda Institute Educators from around the country that 40 vol us used on people with black or chocolate brown hair. I am naturally dark blond; have fair, yellow-toned skin; and green eyes. How could she not notice this? I also learned she used the LIGHTEST POSSIBLE Lift-Color-Method possible: 40vol/Deep 12-N/Shower cap. I was also told that \"no one\" tones blond hair that is 3 feet long. Because the initial color chemical was so strong, when it washed out of my hair, it stripped color from the rest of my hair because it was still developing 45 minutes later. My scalp even turned white. \n\nAngie Perino Nelson is arrogant, reckless, and does not understand blonding.  She should advertise at her other job, Mood Swings Salon, that she is a color specialist sans blonding. This will take me 6 years to grow out damaged hair and about $1K to make it live-able. I can't speak for other EDUCATORS at this institute, but I can speak for Nelson. DO NOT TRUST HER.
