Locks (of Hair) dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Martha Clarke
Although it usually refers to a vanity item, it symbolizes the superior force of will and knowledge. For this reason, when you have long and healthy hair in a dream, the image indicates that you are able to succeed. By contrast, if it falls or if it is cut, the image reflects fear and insecurity; it predicts loss of prestige and power. However, to get a haircut voluntarily indicates liberation, renunciation, and sacrifice. In the event that you shave your head, it means you reject all earthly matters in the pursuit of purity of spirit. And regarding the vanity aspect mentioned, dreaming that someone combs your hair expresses you are too concerned about your external image.
If in your dream, you have your hair loose to the wind, it indicates that you need more freedom to express your feelings. Body hair, meanwhile, symbolizes the primitive and instinctive force.
To get a haircut can show conformity. In the past, they used to cut the hair of prisoners, soldiers, and school boys. When the Beatles grew their hair long back in the sixties, they unconsciously expressed a generational revelation.
