If you dreamed about vinegar in someone else's hair: It is not a good day to make sudden decisions, try not to enter into controversial environments. Seeing vinegar in someone else's hair in a dream is the symbol of wealth and lice in the hair. It means that the person will lead a quality life and earn income. It is interpreted that the person who sees the vinegar on the head of someone will take a loan from a familiar person and will continue his life with the financial support he received from this person.
