Answered by Shaykh Faraz Rabbani
asalaamu alaykum,
I was interested in purchasing a product in which one of the ingredients is human hair keratin. Is it permissible to use?
Walaikum assalam wa rahmatullah,
I pray that this finds you well, and in the best of health and spirits. May Allah grant you all good and success in this life and the next.
It is not permitted to use any part of a human in products, because of the inviolability of the human body. [ Haskafi, al-Durr al-Mukhtar ]
Thus, if the ingredient you mention is known to be from a human source, it would appear to be impermissible to use.
And Allah alone gives success.
