When you use the services of a real professional, go to the appointment with an open mind. You may have your heart set of pale blond, but if the colorist can prove to you that a deep strawberry is really your best shade, listen to her. She is trained to match color with skin tone. She knows what will work, and what won't.
Then how committed are you to your color choice? In other words are you ready for a permanent change or are you still dabbling so that semi_permanent color would be a safer way to go?
