Is it permissible for a sister to remove the hijab that she was forced by her family to wear until she becomes convinced of it, and how can she be convinced to remain steadfast in it?

The hijab is an obligatory duty for the Muslim woman, and it is not permissible for her to remove it, considering the severe warnings mentioned in the texts for women who display their adornments (tabarruj). Her guardian is responsible for her before Allah Almighty, and he must compel her to wear the hijab. It is not permissible for him to condone her display of adornments.
