When is the best time to trim hair to promote growth according to traditional beliefs?

The belief that trimming hair during a full moon promotes growth is rooted in traditional practices and folklore. Traditionally, a full moon is seen as a time of abundance and height, and many cultures hold the belief that hair, much like plants, benefits from the gravitational pull associated with the full moon, resulting in increased growth.

The idea is that during the full moon, the increased moisture in the atmosphere encourages hair follicles to become more active, thus promoting faster and healthier growth when hair is cut at this time. Additionally, various cultures have long linked lunar phases with agricultural practices, where the full moon is viewed as the optimum time for planting and harvesting, and this logic extends into personal grooming rituals as well.

In contrast, other phases of the moon, like the waxing moon or new moon, may be believed to affect growth differently or to inhibit it. The waxing moon is often thought to encourage fullness and growth but not as strongly as the full moon. The new moon is traditionally associated with a phase of rest and beginnings, and while it may be a good time for starting new projects, it's not seen as the best time for promoting hair growth. Therefore, the full moon stands out as the optimal time for trimming hair to encourage its rapid and healthy growth.
