Never ask a mother...or anyone for that matter..
Especially a mother. It's rare that any mother likes to see her son with a shaved head.
I was a lucky exception in that mine complimented how it made me look younger.
If your hair is controlling you in a bad way then the best solution would be to just shave/buzz it. Then you don't have to think about your hair. Instead you can say to yourself this is me, this is who I'm.
Don't let anyone else decide who you are, you know it yourself.
