I was jokingly telling them i will post something about it in my blog. There are certain symbological meaning (and religious and cultural perspective) behind shaving the head.
If you look carefully you will notice that head-shaving is a part of the Buddhist, Christian, Muslim, Jain and Hindu traditions. Buddhist and Christian monks generally undergo some form of head-shaving during their ordination. Brahmin children have their heads ritualistically shaved before beginning school.
In some parts of the Theravada Buddhist world, it is common practice to shave the heads of children.
Why does hindu religion has this practice of the devotees to shave their head on religious programs, pilgrimage? Even for the lay hindu, when their father or near one dies they need to shave their head.
Why does Buddhist monks shave their head? Why Buddha did it?

Why muslims are encouraged to shave their head during the important pilgrimage (hajj)?
