If you’re anything like me, you’re already thinking about your holiday hair plans. In light of CurlyNikki’s STUPENDOUS 4 week curls, I’m dying to know: do you wash your hair as needed? Or do you have a hair wash schedule? I generally wash my hair when it looks or feels dirty; which tends to be every 10-14 days. Following my regular routine would put hair washing day somewhere between December 23-27, but I hate the idea of subjecting my family to my 4 hour hair session this weekend, considering that I’ll be sharing a bathroom. I doubt I’ll be able to stretch my current set for another 5 days, so I’ll be washing, conditioning & restyling my NON-DIRTY hair.

What about you? How often do you wash? Do you think it plays a role in length retention?
