It is known that Moon phases influence life on earth like the tides, agriculture (sowing, harvesting and other specific activities), health, mood, beauty and so on.
As for the hair, which is a symbol of feminine beauty, it is also subject to Moon influence. Hair restoration treatments are most effective if done when the Moon is in the first quarter (Moon increasing). Cut your hair in the 3 days before the Full Moon and the hair will grow faster and stronger. I choose to cut my curly hair in this period, once every 2 months, for years. For a sustainable perm hair choose the period of time when the Moon is decreasing and for a light hair, casual, choose the Full Moon period, when there is a harmony between hairstyle and facial expressions. If you want to dye your hair, choose the period of time when the Moon is increasing, because the hair dye is applied better and the color lasts longer.
