A hairbrush is a tool used for grooming purposes. Brushes and combs are symbolic of vanity, grooming for self-glory, and examining oneself. It could also represent cleanliness and professionalism.

Positive: Dreaming of brushing hair could represent introspection or examining oneself so they can be cleansed and purified. A hairbrush could also represent taking care of yourself spiritually.

Negative: In a dream, a hairbrush could represent one’s vanity or self-glory if they are constantly trying to do their hair or look good. It could also symbolize one who seeks their own glory over God’s.

(2 Samuel 14:25-26; Genesis 13:10-11).
