I have naturally wavy hair and choose to wear it that way most of the time, especially now that I live in Ann Arbor where a DryBar has yet to open. (Totally unsubtle hint, Alli Webb.). However, achieving beachy waves is trickier as you become older and hair becomes dryer and more fuzz-prone—a reality for anyone who colors, blow-dries, flat-irons or is in the throes of peri, post or full-blown menopause. So basically, all of us.
