While a colour refresh might be a good idea before your big day, make sure you don't do it (or get a hue you haven't had before) too close to the date. "[This] won't leave any time to change or correct any tones or hues don't like," said celebrity hairstylist Linet Keshishian. If you'd like to change the colour of your hair do it subtly over a few months. "A gradual colour change is safer and easier to get adjusted to," Keshishian said.
