Hair on the head in a dream is wealth and long life. Whoever sees his hair long, his wealth and life will increase. Long hair for a worried person is an increase in his worry, and for a happy person, an increase in his joy. A woman's hair is her adornment, her covering, and her husband. Braiding hair indicates collecting money and perfecting matters. Beautiful hair indicates honor and nobility.

Hair indicates prestige and wealth. Whoever sees his hair long, his life will be long and his deeds good. Shaving hair during the Hajj season is security and payment of debt. Outside the Hajj season, it indicates poverty and dismissal from a position. Gray hair (Shayb) is dignity and reverence, and it may indicate long life or weakness.

Hair is interpreted as adornment, leadership, and wealth. The longer and more beautiful the hair, the more praiseworthy it is for a woman. It might be a worry for a man if it is excessively long. Whoever sees his hair become like pig's hair will be afflicted with hardships. Whoever sees himself combing his hair is removing worries from himself.
