What is the ruling on using medications that prevent the growth of unwanted hair?

Question:
The questioner asks: What is the ruling on using medications that permanently prevent the growth of unwanted hair, such as armpit hair and pubic hair?

Answer:
That is not permissible. This is not permissible, because it harms the body. The growth of hair in the armpits and the growth of hair in the pubic area are beneficial for the body. However, do not let it grow long. Do not let the armpit hair grow long, and do not let the pubic hair grow long. Rather, remove it every week; that is better. Otherwise, do not leave it for more than forty days. Do not leave it for more than forty days, because this is among the characteristics of the fitrah (the innate natural disposition), among the traditions of the Prophets, and among cleanliness. As for destroying it so that it does not grow at all, there is no benefit for the body in that; rather, there is harm in it. Yes.
