Ruling on using black henna

Question: 150424

Is it permissible to use black henna, knowing that many doctors think that it is harmful to a woman or to her unborn child?.

Praise be to Allah, and peace and blessings be upon the Messenger of Allah and his family.

The basic principle with regard to women using henna is
that it is permissible, because it is one of their adornments. For a
discussion on that please see the answer to question no.

If there is a type of henna or any other product that is used
for beautification and adornment that is medically proven to be harmful to
health, it is haraam to use it because of that, because if it is proven that
anything is harmful, then it is established that it is haraam.

If it is not proven to be harmful, then we go back to the
basic principle which is that it is permissible, and we have not come across
any scientific study that reliably proves that black henna is harmful to
health such that we could rule that it is haraam. Reference should be made
concerning that to specialists, and if it is proven that it is harmful, one
should act upon that and keep away from it.

And Allah knows best.
