These beliefs are descended from ancient Greece and Rome, throughout the Middle Ages, and up to the present. Now they are commonly found in folklore and in manuscripts. Until today, many important rituals and ceremonies were often timed to match the milestones of the lunar month. Many modern discoveries are made that reproves the correlation between moon phases and humans. “Lunar hair care” is also one of the forgotten discoveries that our ancestor’s logical brains discovered but due to lack of documentation, it all vanished.
