Question:
Is it allowed to peel off dandruff off the head on Shabbat?
Answer:
Hello!
It is forbidden to peel off dandruff since this is a ‘chashash’ malacha of ‘gozez’.
Indeed, detached dandruff, which are placed on the hair – are allowed to be removed, and there is no arbitrator in this, and because it is assigned – but be careful! Not to remove those that are attached to the body, even slightly
Greetings Rabbi Chaim Zafarani.
