Is it permissible to consume proteins (enzymes) that are taken from human hair?

It is clear that this is haram to consume, and according to the texts, there is unanimous consensus that it is haram to consume any part of a human being due to the respect that it should be given.

This includes all parts of the human, whether it is [s. consumed] in its original state or whether it has been changed artificially [s. into another state].

السؤال : هل يجوز تناولُ بروتيناتٍ مستخرجةٍ من شعر الإنسان ؟ الجواب : الذي يظهر حرمةُ تناولِ ذلك ؛ فالمنصوصُ عليه أنه يحرم بالإجماع أكلُ جزءِ الإنسان لاحترامه وهذا شامل لكلَّ شيء منه سواء كان على حاله أو تغير بالصناعة .
