Upsherin

The upsherin (Yiddish, shearing off) is the ceremonial first haircut given to a boy at the age of three, at which the hair is cut but the sidelocks (peyot) are left, marking the point from which he will wear them. Widespread among Hasidic and many other communities (a parallel Sephardi custom is called halaqah), it is often observed with a small celebration at which relatives and guests each take a turn with the scissors. The age of three is commonly linked to a verse in Leviticus that compares a young fruit tree, whose fruit may not be eaten in its first three years, to a child, and the milestone frequently coincides with the boy's first wearing of a skullcap and prayer fringes and his introduction to the study of the Hebrew letters. The custom is not mentioned in the Talmud and became widespread later, gaining its particular importance within Kabbalistic and Hasidic circles.

The custom's documented rise is specifically Kabbalistic: Chaim Vital, the chief recorder of the teachings of Isaac Luria, the Arizal, describes his teacher performing the first haircut of his own grandson at the tomb of the second-century sage Shimon bar Yochai in Meron on Lag BaOmer in the sixteenth century, an episode later Hasidic sources cite as the origin of the now-widespread custom of holding upsherin ceremonies at Meron on that specific date each year, drawing large crowds of families to the site for the occasion even though the underlying practice had no attested precedent before this Safed circle.

Upsherin is not a universal Jewish practice observed across all communities; it is specifically a Hasidic and closely related Kabbalistic custom, absent from mainstream Sephardi practice and not treated as required even in much of non-Hasidic Ashkenazi Orthodoxy, which is why a three year old boy's first haircut looks like a significant milestone in some Jewish communities and passes unmarked in others. Its most commonly cited justification borrows an analogy from a Torah law that has nothing to do with children at all: Leviticus's rule that a newly planted fruit tree's produce is forbidden for its first three years and only becomes usable, eventually sacred, in the years that follow, a law some Kabbalistic sources read as a template for a child's early development, treating the first three years as a period before certain religious markers, cutting the hair among them, are appropriate.

The custom's best known public expression is not a private family event at all but a mass celebration held at the tomb of the second century sage Shimon bar Yochai in the town of Meron on the festival of Lag BaOmer, where families from across the Hasidic and wider Orthodox world bring three year old boys to receive their first haircut amid large crowds, music, and celebration, a single site and occasion that has done more than any other to make upsherin visible outside the specific communities that originated it.
