The question arise, How do we know all the Guru's kept there hair. Guru ji has advised his Sikhs to keep hair and so the Gurus lead by example right from the first Guru, Guru Nanak Dev ji. The Gurus always lead by example and this was also shown when Guru Gobind Singh Sahib ji took amrit from the Panj Pyare. Whatever the case the Gurus always lead by example. When Bab Budha ji passed away Guru Hargobind gave his shoulder to the bier showing the Humility that existed in the Gurus. Furthermore, when Guru Arjan Dev ji was put on the hot plate he also lead my example showing us how much love toward the Lord he had and we too should love and devote our lives for the Lord in the same way. God's will is what the Gurus lived by and they advised us in the same way to keep hair along with other teachings. Its well understood that hair is sacred in Sikhi and it should be kept as God has made it, otherwise Guru Gobind Sahib ji would have given the Khalsa Panth 4 Kakkar and his Hukam for the Sikh would have not included - Sikh must keep hair. Also hair has more to do than just identity because if it didn’t then Guru Gobind Singh Sahib ji would have just said wear a pagg and the 4 Kakkar and still the Khalsa Panth will be distinctive and same goes for the Sikh they would just wear the pagg and look distinctive. But that is not the case he advised his Sikhs to keep hair because of identity and spirituality.
