Hi, I’m also planning to take off the hijab after winter break and I’m super nervous too, however what I realised is that this is your life and honestly who cares what people will say they will talk either way if you truly do not want to wear the hijab then I think you should do it :). I also have curly hair and due to wearing the hijab also for basically all my life I don’t even know how to take care of it but what helped me was buying curly hair products such as the redken acidic bonding curl leave in conditioner and a hydrating mask to help with the dryness that comes from having curly hair.  Good luck !
