I have noticed while reading up on early modern European history (particularly concerning the British parliament) that pictures of nobility often feature nobles with with really long hair almost like that of a Spaniel. What is it with curly long hair that stuck with nobility that until now this type of hairstyle has been associated to nobility and prestige so much so until now the House of Lords ceremonial outfit or judges are seen with long wigs?
BTW the English nobility before and during the Civil War of England were so notoriously known for their luscious locks that that a faction parliamentarian dissenters identified as Roundheads, people who had a normal set of hair (though moderately long by modern standards). This just adds to the fact that 17th century English Nobility are known for their really long hair.
So going back to the question, why does it have to be long and curly?
