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.
That's not to say you're going to duplicate the salon experience at home any time soon exactly. But it also doesn't mean the over the bathroom sink approach can't be more enjoyable, or pleasant even, now does it?In other words we've come a long way, baby when it comes to coloring our hair.
