Hairstyles of the British Court: Whigs in Wigs. Not bad, but mostly on ride and fall of wigs in law.
Interesting graf on starched wigs/food and guinea pigs:
In England the problem was food. England hovered on the brink of starvation and, given that the starch portion of the “starch and plaster of Paris” mentioned above was derived from wheat; cavorting about with a shovel full of what was essentially wasted food in your wig was simply not a good idea for the well fed well-to-do. Even then, the haughty rich continued to do it anyway, and the flouting of it in the face of famine became such an issue that a tax was imposed on those who wore powdered wigs to the tune of a guinea each, which actually netted a hefty sum of £200,000 in just the year 1795. This gluttonous consumption of food for the purpose of powdering their wigs, and the elite being willing to pay the tax rather than dispense with their vanity, got these wig-wearers the nick-name “guinea pigs” by the populace (McLaren 244).
