End-Of-The-Week Hair

I've been washing my hair every 6-7 days. Towards the end of the week, my hair isn't really in much of a presentable state. At that time, I depend upon styles that "mask" my hair. The style I lean towards when my hair isn't "fresh" is the messy bun. I just grab my hair any sort of way and put an Ouchless elastic on. I don't twist the elastic - that way, my bun remains big and isn't restricted by the tightness of the elastic.
