In Pakistan many women loosely wear a dupatta on their heads. This reveals their hairs just above the forehead and some part of their neck. Does this fulfill the requirement of the Hijab?

The dupatta style of hijab in essence fits the prescription of a valid hijab only if a woman tightens the loose part which reveals part of her hair and covers her whole neck. Dupatta style is signified with its bright colors and beautiful embroidery and represents the enriching variation of different Islamic cultures.
