It's unfortunate, but a lot of parents think they have a right to tell their children how and what to feel. Many parents simply don't realize how instead their parenting is supposed to be about helping their children actually understand their emotions and gradually be ok with their own feelings about things they experience.

Actually, the fact that you felt uncomfortable about your mother seeing you with your head shaved tells me that your mother taught you to worry about what others think instead of being confident in yourself and comfortable with yourself. Her praise is conditional and based on her preferences and likes, not yours or anyones for that matter. She is acting like she owns you instead of respecting your personal space that is now yours and no longer hers. Her love is conditional instead of being unconditional which is what you feel when you are around her or interact with her. Always telling you what she needs you to be instead of supporting you for what YOU want to be.
