Is this a fair way to treat a 15 year old? (Muslim)?

[Beccy]

My best friend is 15 and is a Muslim (Pakistani origin but her and her mu were born in the UK). She has very restricting rules that most Muslims do not have to follow and I'm wondering is this fair and is it part of the religion.
she cant go out the house without her mum except school
she cant talk to the opposite gender except teachers
she cant have friends not in her school year
she cant go round her friends houses
she cant shave her legs and they're really hairy
she cant have her eyebrows done
her phone is checked
she cannot have any social media accounts
she's banned from certain music
she once touched a homeless man on the back and her mum went crazy. not because he was homeless but because he was male
She has to wear t-shirts which go down to the knee
she couldn't pick her GCSE options (she's doing German, French, History and Geography)
she won't be allowed to pick her AS levels
she can't pick her sixth form/college
she can't pick her university
what i find most disturbing is her mum threatens to make her go to university in Pakistan if she gets bad grades
Her mother is also currently doing a degree and she says if she gets a boyfriend she will leave her degree and stop working. Her mother didn't eat for 2 days the last time she tried to get a boyfriend. is this right and what can she do?

No, it is totally wrong what she has been doing. Blackmailing, and Torturing her daughter. If your friend dose not step up and confront her mother this will never end and trust me her mom will die one day and your friend will be stuck with the decisions her mom made for her for life well with most of them..
I know it will be very hard for her to do that (confront) her mother but she has no other choice..

I understand a few of those. Muslims can't date, so I understand why she can't talk to males. Girls can't wear shorts so there's no need to shave your legs. Social media would allow her to be able to talk to males and becomes friends with them. So would leaving the house without her Mom.

With that being said, not all Muslims follow that. I have a friend at school who is Muslim, and she has guy friends, including me. But she wasn't allowed to talk unnecessarily to boys when she was younger. She has never had a boyfriend (such a shame because she is really pretty haha). She wasn't allowed to have any social media accounts before, and now she can, She's 18 now and goes to a boarding high school like me. She told us that her dad would threaten to send her to Pakistan if she didn't follow any of the rules but since she did, she gets a bit of independence. I think it's unfair, but it's honestly part of Muslim culture. A good Muslim should follow those things, but most don't anymore. Just be there for her. She needs a friend to help her get through her cultural restrictions.
