I want to ask about the sunnat e muwakkadah of not cutting hair and beard from the end of month of shawwal for those performing hajj.
Are we allowed to shave the tiny hair growing on cheeks and trim small some parts, while leaving the main beard untouched.
Similarly for the hair, are we allowed to trim side and back of head which might start to look uneven because of a specific hairstyle that requires regular upkeep?

Yes it is allowed
