Brushing / Styling Hair dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Martha Clarke
To dream that you are styling your hair indicates that you are concerned with your physical appearance. This type of image should put you on alert: dressing up in an exaggerated manner is a sign of falseness in human relationships. Not in vain, when we modify our image, we can momentarily avoid facing our faults. Soon or later, however, the mask must fall and your costume can no longer hide reality.
To find yourself in danger is an indication of success; to escape it has an inverted symbolism, it predicts misfortune.
