Ruling on women curling their hair
Question

                Some female students with fine hair try to make it thicker in the ways that are known to girls. What is the ruling on that, knowing that this is one of the things that westerners do?
Praise be to Allah.
    The scholars say: there is nothing wrong with curling the 
    hair. If a woman curls her hair in a manner that does not imitate the way 
    that immoral kaafir women curl their hair, there is nothing wrong with that.
