The definition of skin is: my body, identity, protection, boundary and self-image.
Shaving your head means low psychological energy.
This dream is an expression, and your self-image has been damaged. Maybe something happened in your life recently (probably related to your feelings), which made you feel a little embarrassed and wanted to make up to cover it up (buy a wig). Fortunately, you have a strong ability of self-repair, and you grow new hair during the development of your dream-it represents your creativity, rebirth and regeneration.
Believe in yourself and make good use of your advantages. You can definitely get out of trouble!
