How can I convince my parents that I need a haircut? They say no because I'm from a Sikh family but I don't believe in religion. Because of the type of lifestyle I have, my hair has to be tied tightly for quite some time everyday and I'm starting to bald from the front. I went to the doctor and he also told me to get it cut my dad said no. He says that it would hurt my grandparents a lot if I cut it because they are very deeply religious. It's interfering with my life and I jut want to get it cut. I'm 18 but I don't want to do without telling my parents coz I love them a lot. What do I do?
