Roland Piquepaille writes "You all know that agricultural crop production relies on fertilizers, such as composted waste materials. But I bet you wouldn't have thought to add human hair to animal manure to produce better and greener fertilizers.

Apparently, barbershops and hair salons are selling human hair for a couple of years now — a fact I didn't know. Anyway, even if human hair can be used to grow some plants, 'further research is necessary to determine whether human hair waste is a viable option as fertilizer for edible crops.'
