I do not belong to a religious family. My parents do believe in Allah and Islamic teachings yet hardly offer prayers. Subsequently, I too did not have much strong religious hold. However suddenly I was diverted to Islam and since 18 years of my age I have been offering prayer and trying to follow Islam as much possible. However last year I had decided to go for hijab but my family resented which I resisted and continued covering my hair. But now I am losing my hair and the doctor advised me not to cover it firmly and since then I am covering my hair with duppatta making sure that most of my hair is covered. Is this permissible for me?
