Is a divorced woman required to cover her hair in shool?
Answer:
Generally a woman who was once married should continue to cover her hair even after being widowed or divorced [see Shu”t Shvut Yaakov 1:103]. However, when there is a great need to go uncovered, for the purpose of getting remarried, getting a job etc. there is room for leniency for a widowed or divorced woman to go with her hair uncovered, see Igros Moshe [Even Haezer 1:57,4:32]
