Failure to have a ghd (good hair day) can lead to disasters of all sorts, including missed appointments, rotten moods, massive headgear and the return of the babushka. One UK company realized this early on, and has been helping to keep coif catastrophes at bay since their flagship flatiron first made them famous with marquee idols and mere mortals alike. They've given flocks of females freedom from shrouding their strands under schmattas-and if that doesn't entitle them to the name ghd, nothing does.
