I'm about to go down in your estimations. Way down. I sat and calculated the amount of time it's been since I had my colour done (that's not even the worst part) and it's bad. Real bad. It's been 18 weeks. Surely not?! Yes. 18. But, in my defence, I have balayage, which means I can still pass as a semi-upstanding member of society with roots. It's the style, man. Still, it put the shivers in my timbers and got me thinking, how many of you have the time/inclination to have your colour topped up every eight weeks? How often do you get it done?
