Is it obligatory for a woman in a state of major ritual impurity to wash the roots of her hair, or is it sufficient to wipe it?

Question:
(peace and blessings be upon him). The questioner asks: If a woman in a state of major ritual impurity wants to perform the full ritual bath, 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 the roots. The Prophet (peace and blessings be upon him) said: Therefore, it is obligatory to bring the water to the roots of the hair and to rub the head with water until it is saturated. Yes.
