Sikhism is a great religion and I will say you should devote some time in studying religion and also the concept of hair and history of hair in Sikhism. Once you will give yourself time to do so and the efforts you will put into learning about Sikhism it will make you feel proud of your hair and will also help you become a confident succesful individual as well. I will say give a few years in learning about Sikhism and see how you feel afterwards. Also a big factor in Sikhism is Sangat so try to attend some retreats where you learn with Sangat and that will also help you know Sikhi more in a very genuine positive way.
