If you have dreamed of being sad that your hair has been cut: You should act more wisely in commercial matters, you should reconsider your income-expenditure balance, details such as receivables or regular payments. Being sad that one's hair is cut in a dream means that the dreamer will catch a disease, his health will deteriorate, he will not be able to get rid of the effects of bad events, his morale will be bad and he will be unhappy.
It means that the person will be shaken by learning bad and sad things about his health. It signifies experiencing a difficult illness, long-term treatment, and therefore demoralization.
