Nano-Grecian Formula One?

New research by French scientists seems to suggest that the techniques used by Greeks and Romans to dye their hair had results in common with today's nanotechnology and were comparable to modern products.

Researcher Philippe Walter, a senior scientist at the Research and Restoration Center of French Museums, in collaboration with L’Oreal Research, has been working with ancient hair dye formulas, and has found that the procedures really work. "During the 2nd century [C.E.], Claudius Galen, the most famous doctor in the Roman Empire, precisely described the use of a mixture of lead oxide and slaked lime to dye hair black," Walter told Discovery News.
