During the consultation, your stylist should ask questions, too. It's important that you're 100 percent honest. Have you colored your hair at home using a box treatment? What products do you use currently? What is your styling routine? How often do you want to visit the salon for touch-ups? All of these factors can affect how your hair will react to the bleach. Based on your responses, your colorist might make a different plan of action when it comes to creating your custom color.
