Today marks the official first day of Fall. Do you feel a crispness in the air already? Here, in San Francisco, not so much, as we're going through a bit of a heat wave these days. However, every time we experience an official change of season, this get gets me to thinking about switching up the old hair color palette. So tell me: No matter the season, do you go lighter when the flowers start blooming in March, get your streak on when the warmer-weather rolls in, and/or go dramatically dark for the cooler months? Or is it just that you have your own hair color schedule?
