Cutting or styling your hair during a full moon makes it grow faster or thicker.
Hair growth is determined by genetics, hormones, nutrition, and age, not moon phases. Studies show no correlation between lunar cycles and hair growth rates. This myth likely persists because people may coincidentally cut their hair more often around full moons, giving the impression of faster growth.
