Dream about messy hair is a signal for feelings of insignificance, helplessness and unworthiness. You need some intellectual stimulation. A loss of a good friend or a deterioration of your instincts. This dream is a metaphor for imitation. You need to proceed at a steady pace in realizing your goals.
Messy hair dream indicates a need for self-renewal and escape from everyday problems. You are not fully recognizing and dealing with some part of your emotions. You are lacking a certain quality of a person you are working with and need to incorporate that quality within your own self. It signals your adaptability and versatility to various situations. Something is lacking in your life.
If you dreamt about messy hair:
Some days just aren’t going to go very well, and you can’t hold yourself responsible! The best thing you can do is to stick to what you know. You know, for example, that eight glasses of water is the daily dietary minimum (double it if you wish). You also know that personal time is important to you (even though you tend to pretend it is not). Regardless of the surprises the day may bring, take comfort in the good things that you can always do for yourself.
