<human>: I've had long hair my whole life because my mother didn't allow me to cut it. I finally recently cut it into a cute fauxhawk. I go to school out of state, and I was skyping with my little sister and mother and showed them my hair. My mother didn't say much, but she later called me and informed me that she doesn't want my sister around that and I won't be allowed to come see my sister this summer unless I cut my hair into a pixie cut. The real reason is that she thinks it is dykey (I'm not gay and I would be visiting with my boyfriend, so it's not like she thinks I'm actually a lesbian) although she wasn't straightforward about that. 

I know I could just cut it and it would look good but I don't want to encourage her to think she can use my relationship with my little sister as leverage to do whatever she wants... especially something as minor as a hair cut.

I told her I thought she was being manipulative and cruel but she hasn't responded.

What do I do?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My mom thinks my hair makes me look like a lesbian and won't let me see my sister until I cut it.
