Last July I posted a short interview with Brandon Wagner, owner of Tribeca Color Salon (and its new sister store, Becky, in Ybor). Wagner told me how they sweep up all the clipped hair and ship it off to Matter of Trust, an do-gooder organization that reuses natural and man-made items instead of throwing it on top of the ever-growing landfills.
I've heard of other salons in the area who also send their hair to Matter of Trust, so be sure to ask if yours does before booking your next appointment. If they don't, find a place that does!
