In Hindu tradition, the hair from birth is associated with undesirable traits from past lives. Thus at the time of the mundan, the child is freshly shaven to signify freedom from the past and moving into the future. It is also said that the shaving of the hair stimulates proper growth of the brain and nerves, and that the sikha, a tuft at the crown of the head, protects the memory. Hindus practice a variety of rituals from birth to death. Collectively these are known as saṃskāras, meaning rites of purification, and are believed to make the body pure and fit for worship. A boy's first haircut, known as choula, is one such samskara and is considered an event of great auspiciousness. The lawbooks or smritis prescribe that a boy must have his haircut in his first or third year. While complete tonsure is common, some Hindus prefer to leave some hair on the head, distinguishing this rite from the inauspicious tonsure that occurs upon the death of a parent. Those that practice complete tonsure generally ritually offer the hair to their family deity. Many travel to temples such as the famed Tirumala Venkateswara Temple of Lord Vishnu to perform this ceremony. Traditionally, a Hindu girl never has her hair cut after the first haircut which generally happens at the age of 11 months; So the first haircut for the girl is very important because that is the only time they do. However, some Hindus practice a tonsure ceremony for girls as well. The details vary by sect, locality, family, and country. In some Brahmin households, a baby girl's hair is never shaved.

In Israel, there are also non-religious families who adhere to this custom and do not cut their sons' hair until the age of three.

The Aqiqah ceremony involves shaving the child's head seven days after birth and anointing the child’s head with saffron. It is traditional to give in charity gold or silver equal in weight to the hair. This does not have to be done by actually weighing the hair; if it is too difficult to do that, it is sufficient to estimate the weight and give paper currency equivalent to the price of that amount of gold or silver.
Slavic culture
Polish
The ritual first haircut was a pre-Christian, all-Slavic tradition, though it survived in Poland well into the 18th century. This first haircut traditionally took place between the ages of 7 and 10, and was conducted by either the boy's father or a stranger, who would thus enter into the boy's family. Before that age the boy's life was connected to his mother and he was treated as a child. The ritual haircut, coupled with the granting of an additional given name, marked the boy's coming of age and a transition to the world of men, in which he was to be looked after by his father. The ritual also constituted the father's formal act of recognition of the boy as a son.
