In the ancient Middle East hair loss was regarded as shameful. It symbolised the public announcement of the loss of a mans virility.
Samson who lost all his hair, also, well documented in the bible, showed that his head full of hair was not only a symbol, it was also considered the actual source of his power and strength, which he lost when it was cut off by the Philistines, and not by Delilah as most people claim.
In Ancient Egypt, wigs were serious business. The head was shaved for cleanliness, and presumably for coolness, and wigs were worn as protection from the sun and as a sign of regal status.
All Pharaohs were buried with lavish head gear for wearing in the afterlife.
The Egyptians, Romans and Greeks spent fortunes on salves and ointments which they hoped would grow hair or at least help stop hair loss.
The following dates back to the Egyptian times:
