A ponytail on a woman is truely the height of a refined woman. When a woman has her hair up, she has concealed the beauty of her hair. This concealment sets this appearance as her default in our minds and so when she lets it down once in a while, it makes the impact and prettiness of her hair suddenly become amplified. A woman who lets her hair down constantly lowers the value of her long haired state and removes the punch the hair packs when we see it.
