Washing the roots of a woman's hair in the ghusl for janabah

Question:
The questioner asks: If a woman in a state of janabah wants to perform ghusl, does she have to wash the roots of her hair, or is it sufficient to wipe it and wash the rest?

Answer:
No, no, it is necessary to saturate the hair; it is necessary to saturate it with water so that the water reaches its roots. The Messenger (peace and blessings be upon him) said: Therefore, the water must be made to reach the roots of the hair, and the head must be rubbed with water until it is thoroughly wet. Yes.
