the other replier said 'some suggest hair should not be tampered with'.
the guru granth sahib says you must maintain the five k's including 'kesh'. i would consider bleaching any facial hair as the guru granth sahib doesn't forbid this. i guess everyone has their own opinion.....what's yours?
You have an interesting opinion. However, the more important reason for response is to point out that the <5 K's> are from the Rehit of Guru Gobind Singh. But, none of Guru Gobind Singh ji's writings are contained in Siri Guru Granth Sahib.
