I would say to avoid "Sun-in" and agree on 2 things:
1- the brush in types are way better and more natural, but everyone's hair is different & a professional knows how colors work on hair...
2- Salon Picasso is awesome! I've been going there for YEARS and love it - I see Christopher (the owner) - he offers a discount to people who are referred as well! Normally when I get mine done, it's an all over color to hide the gray and then 2 other colors for some fun and with the cut and tip, it's a little over $100 dollars.
