Question

Why did Europeans powder their wigs?

Answer 1

In the 18th century, wigs were powdered in order to give them their distinctive white or off-white color. Wig powder was made from finely ground starch that was scented with orange flower, lavender, or orris root. Wig powder was occasionally colored violet, blue, pink or yellow, but was most often used as white. Powdered wigs became an essential for full dress occasions and continued in use until almost the end of the 18th century. Powdering wigs was messy and inconvenient and the development of the naturally white or off-white powder less wig (made of horsehair) is no doubt what has made the retention of wigs in everyday court dress a practical possibility.
