The only negative I have to say is on this occasion I had to be somewhere. I thought 2 hrs would be more than enough for a wash/root tint/rough dry. It took a lot longer and when I told the stylist who was drying my hair she offered me a hairdryer 😂. So the rough dry was a joint effort. While the stylist was trying to help me get out on time, drying my own hair was not really what I had in mind 😐. But apart from this everything was fine, I just sometimes find things take longer than it says as the stylist is always doing another persons hair in between yours.
