Dreaming of balding signifies that important changes may be coming into your life. It could indicate losing a job or a decline in social status. If you see yourself without a mustache in the dream, it suggests that someone around you, particularly a supervisor or business associate, may face financial losses. This serves as a warning, so you should exercise caution.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Balding" (page 28) â resolved via the equivalent "Baldness" entry.
In a dream, baldness means loss of job or falling in rank. If one sees himself bald-headed in a dream, it means that his superior will lose money in business to the authorities or by a fire that will eat up his property. It also can be interpreted as becoming needy, or if he is indebted, it means that he will payoff his loan. If one sees his hair thinned until it reaches baldness in a dream, it means that he may lose his wealth or perhaps it could mean losing face with the people. If one sees himself sitting with a bald-headed woman in a dream, it means that he is engaging in a project that is tainted with suspicion, or it could mean that he will become a victim to temptation. Seeing a baldheaded woman in a dream also signifies drought and scarcity. In a dream, baldheadedness also means money that is received from one's superior at work and requires tremendous efforts to earn. Such earnings will costs more than what they are worth.
