Can I use a shampoo with pork ingredients if I’m a Muslim?
In the name of Allah, the Most Gracious, the Most Merciful
It should be avoided. The Sharia has considered all parts of a pig as essentially impure [najis al-‘ayn] and it cannot be purified in any way.
Say, “I do not find within that which was revealed to me [anything] forbidden to one who would eat it unless it is a dead animal or blood spilled out or the flesh of swine – for indeed, it is impure – or it is [that slaughtered in] disobedience, dedicated to other than Allah”
