Sooner or later, usually around the first birthday, a call comes from India: "Beta, when are you doing the mundan?"

And if you are raising your child in Toronto, Birmingham, New Jersey or Frankfurt, the questions you ask back are rarely about the date. They are about why. Why shave a toddler’s head at all? Is it actually required, or just expected? What do we do with the hair here, where there is no Ganga down the road? And what will the other children at daycare say?

I took those questions to the three oldest texts that describe this ceremony. The answers turned out to be more practical, and more flexible, than most families expect. One of them even tells the barber what matters most.

Why do Hindus shave a baby’s head?

The ceremony is called mundan in everyday Hindi, but its name in the texts is chudakarana or chudakarma, sometimes chaula. It is one of the traditional sixteen samskaras, the rites that mark a Hindu life, and it follows the naming ceremony and the first-food ceremony. In it, the hair a child was born with is removed for the first time, with prayers and the family present.

So why do it? Search online and you will find a long list of reasons: it removes impurities from the womb or from a past life, it cools the head, it helps teething, it makes the hair grow back thicker. I tried to trace each of these to a text.

“In view of the injunctions of the Veda, the Tonsure-ceremony of all twice-born children should be performed, according to law, in the first year or the third.”

— Manusmriti 2.35, with Medhatithi’s commentary, tr. Ganganatha Jha (courtesy: wisdomlib.org)

The reason the Manusmriti gives is short: it is done “in view of the injunctions of the Veda” and “according to law” — the Sanskrit word is dharmatah, as a matter of dharma. It is presented as a sacrament, not a health measure or a beauty treatment. In the three texts I opened, I did not find the womb-impurity, past-life, cooling or teething explanations. They may come from later writings or from family teaching, but I could not trace them, so I am not repeating them as fact.

The honest short answer: Hindus shave a baby’s head because the household rites prescribe it as one of the samskaras — a marker that the child has passed safely through infancy and is being received into the family’s way of life. Its meaning is religious and familial. It does not need a medical justification to be worth doing.

Does shaving a baby’s head make the hair grow back thicker?

This is the promise every grandmother makes, and the most searched question about mundan in English. Here the evidence is clear.

“No — shaving hair doesn’t change its thickness, color or rate of growth.”

— Mayo Clinic Staff, “Shaving hair: Does shaved hair grow back thicker?” (courtesy: Mayo Clinic)

According to the Mayo Clinic, regrowing hair only seems coarser because shaving leaves each hair with a blunt tip, so it feels stubbly and can look darker for a while. The hair itself has not changed. So if your partner is sceptical because “it doesn’t actually do anything for the hair”, they are right, and it does not matter. That was never the point of the rite.

Is mundan necessary?

Many parents abroad ask this quietly, sometimes because they are unsure, sometimes because one side of the family cares a great deal and the other does not. The texts do not answer it in modern terms, but they do show how much room the tradition leaves.

“In the third year the Caula (i.e. the tonsure of the child’s head), or according to the custom of the family.”

— Ashvalayana Grihya Sutra 1.17.1, tr. Hermann Oldenberg (courtesy: wisdomlib.org)

Notice the second half. The Ashvalayana Grihya Sutra, attached to the Rigveda, gives the third year and then immediately adds “or according to the custom of the family”. The text itself defers to your family’s practice. Whether a family does a full shave, leaves a small tuft (shikha), trims only a lock, or holds the rite at a particular temple has always varied from household to household.

So the practical answer is this: mundan is a prescribed samskara, and for most Hindu families it remains an important one. How and when it is done has always been a family decision, and the texts allow for that.

Which brings us to the question your parents actually asked: when?

At what age should mundan be done?

The first lock is cut with scissors — by the father in many homes, by a maternal uncle or aunt in others.

The three texts agree on a window rather than a single date:

Many families hold that the mundan must fall in an odd year — one, three, five or seven. The two years the texts name are both odd, but I did not find the fifth or seventh year in any of these three. Those probably come through the “custom of the family” route, which is a perfectly legitimate route.

A practical way to decide: start with your family’s custom, ask a pandit for an auspicious date within that year, and then look at your child. Many parents find a one-year-old sits through the shave more calmly than a two-and-a-half-year-old who has learned to be wary of strangers with blades. None of the texts says this; most parents do.

What the texts say about doing it safely

This is the line that surprised me most. In the Paraskara Grihya Sutra, when the father hands the razor to the barber, he says:

“Without wounding him, shave him.”

— Paraskara Grihya Sutra 2.1.21, tr. Hermann Oldenberg (courtesy: wisdomlib.org)

The one instruction to the barber written into the ritual is about the child’s safety. In today’s terms: a new, unused blade, clean hands, and two adults gently holding the child. For a very small or wriggly child, many families choose an electric clipper to take the hair very short rather than a razor. If the child is unwell, has a fever, or has a rash, sores or crusting on the scalp, postpone and see your paediatrician first. The rite will be just as meaningful a week later.

Everything needed fits on one plate — plus a clean blade and a soft cap.

How to do mundan at home

The Grihya Sutras describe it as a household rite — the word grihya itself means “of the home”. A short home version most families follow:

  1. Choose the day and time — family custom first, then an auspicious date. Morning works best, when the child is rested and fed.
  2. Set up a simple altar — a low stool with a red or yellow cloth, an image of Ganesha, a kalash, a lamp, roli, rice and flowers. See puja at home without a temple nearby.
  3. Sankalp and Ganesh puja — parents state their intention. A small havan is optional; here is how to do a havan at home without a pandit.
  4. The first lock — cut with scissors by the father, or by whoever your family custom names.
  5. The shave — by a barber or an experienced family member.
  6. Collect the hair on a white cloth, a leaf or a ball of dough, so none falls on the floor.
  7. Bath, new clothes, blessings — a lukewarm bath, fresh clothes, blessings from elders, a gift for the barber and a family meal.

One more detail from the Ashvalayana Grihya Sutra (1.17.11): each time hair is cut, it is handed, with shami leaves, to the mother. Her role in the ceremony is not only to hold the child, but to keep what is cut.

And that leads to the question every family abroad eventually asks: what do we actually do with the hair?

What to do with mundan hair outside India

The hair is never left to scatter — it is gathered and kept.

In India, most families immerse the hair in the Ganga or another sacred river, or offer it at a pilgrimage temple such as Tirupati. But the oldest instruction is different, and far easier to follow abroad.

“Having put away that lump of dung with the hair so that it is hidden in a cow-stable, or in a small pond, or in the vicinity of water.”

— Paraskara Grihya Sutra 2.1, tr. Hermann Oldenberg (courtesy: wisdomlib.org)

The Paraskara Grihya Sutra says the hair is wrapped in a lump of cow dung and hidden — in a cow-stable, a small pond, or near water. The emphasis is not on a river at all. It is on putting the hair away respectfully, so that it is not scattered or trodden on. River immersion is a later and very beautiful expression of the same idea.

Immersion at a ghat — today’s form of the old “near water”.

Three options that families abroad use, all close to that original idea:

Home, temple or pilgrimage — and the winter problem

Many families hold the mundan at the family deity’s temple — also “custom of the family”.

Many families hold the mundan at their kuldevi or kuldevta temple in India, and plan the rite around a trip home. Others go to a pilgrimage site. Both fall within the Ashvalayana’s “custom of the family”. But because the Grihya Sutras treat it as a household rite, a mundan done at home is not a lesser mundan.

In a cold country, the most important item after the blade is a soft cap.

If the “right” year falls in a Canadian January, remember the window the texts give — Paraskara’s “before the third year has passed” and Ashvalayana’s family custom. Many families abroad simply wait for spring or summer. If it has to be winter, keep the room warm and the head covered with a soft cotton or wool cap.

Explaining it at daycare or school

A shaved head in a classroom gets noticed. A short note to the teacher the day before helps — “this weekend we held a family ceremony for our child’s first haircut” — so they can answer other children calmly. Give your child one simple sentence too: “It was my first haircut. It’s a special thing my family does.” For older siblings who ask harder questions, see how to explain Hinduism to a child.

Can girls have a mundan?

In many families a daughter’s mundan is celebrated exactly like a son’s.

Yes. The Paraskara text is written entirely for a son, and I found no separate mention of daughters there. But the Ashvalayana closes its description with this line:

“The rite only (without the Mantras) for a girl.”

— Ashvalayana Grihya Sutra 1.17.19, tr. Hermann Oldenberg (courtesy: wisdomlib.org)

So the chudakarana for a daughter is in the text itself — the same act, without the recited verses. Today many families do a full mundan for daughters; others cut only a lock or a little hair. Both are living traditions. The text does not leave daughters out.

Scalp care after mundan

None of the Grihya Sutras I read says what to put on the head afterwards. Turmeric, sandalwood paste, curd or coconut oil are family traditions. I could not open a paediatric source this time that recommends any particular oil or paste, so I am not naming one. The common-sense precautions:

What I found, and what I did not

“Not found” does not mean “does not exist”. It is the honest result of my search, not a final verdict.

The short version. Hindus shave a baby’s head as a samskara — chudakarana — prescribed in the first or third year, and one of the oldest texts explicitly allows the custom of your own family to decide. Daughters are included. The first instruction to the barber is the child’s safety, and the hair is meant to be put away respectfully — which, outside India, can be as simple as the soil of your own garden.

It will not make the hair thicker. It was never meant to. It is a morning when the whole family puts its hands on one small head and blesses it. For the larger picture of passing these traditions on, see raising children with Indian values abroad.

Frequently asked questions

Why do Hindus shave a baby’s head?
Hindus shave a baby’s head as part of chudakarana (also called chudakarma or mundan), one of the traditional sixteen samskaras or rites of passage. The Manusmriti 2.35 says the tonsure should be performed “in view of the injunctions of the Veda” and “according to law” (dharmatah) in the first or third year — so its stated purpose is religious, not medical. The Grihya Sutras describe it as a household rite with prayers, the first lock cut in the family’s presence, and the hair put away respectfully. Popular explanations such as removing impurity from the womb or a past life, cooling the head or easing teething were not found in the Paraskara Grihya Sutra, Ashvalayana Grihya Sutra or Manusmriti. Today it is mainly a family blessing marking that the child has passed safely through infancy.
Is mundan necessary?
Mundan (chudakarana) is a prescribed samskara in the household texts, and for most Hindu families it remains important. But the texts themselves leave room for family practice. The Ashvalayana Grihya Sutra 1.17.1 says the tonsure is done “in the third year, or according to the custom of the family”. That is why practice varies: some families shave the whole head, some leave a small tuft (shikha), some cut only a lock, and some hold the rite at a particular temple. Whether and how to do it is ultimately a family decision. If the child is unwell or has a scalp problem, it can be postponed without losing its meaning. It has no proven medical benefit, so the decision rests on faith and family tradition rather than health.
At what age should mundan be done?
The texts give a window rather than a single date. The Paraskara Grihya Sutra 2.1.1–2 says when the child is one year old, or before the third year has passed. The Manusmriti 2.35 says the first year or the third, and its commentator Medhatithi explains that the choice between them depends on planetary positions. The Ashvalayana Grihya Sutra 1.17.1 says the third year, or according to family custom. Many families follow an odd-year rule (1, 3, 5 or 7); the fifth and seventh years were not found in these three texts and come through family custom. In practice: follow your family’s custom, ask a pandit for an auspicious date, and consider how calmly your child will sit through it.
Does shaving a baby’s head make hair grow back thicker?
No. According to the Mayo Clinic, shaving hair does not change its thickness, colour or rate of growth. Regrowing hair only seems thicker or darker because shaving leaves each hair with a blunt tip, so it feels coarse and stubbly for a while. A child’s hair growth depends on age, genetics, nutrition and health, not on whether the head was shaved. This does not make mundan pointless: the Manusmriti 2.35 presents the tonsure as a religious duty performed “according to law”, not as a hair treatment. Families can keep the ceremony for its meaning while setting aside the promise of thicker hair.
What do you do with mundan hair abroad?
The oldest instruction is easier to follow abroad than most people think. The Paraskara Grihya Sutra 2.1 says the hair, placed in a lump of cow dung, is hidden in a cow-stable, a small pond, or near water — the emphasis is on putting it away respectfully, not on a river. The Ashvalayana Grihya Sutra 1.17.11 adds that cut hair is handed to the mother with shami leaves. Outside India, families commonly bury the hair in the garden or a large plant pot, ideally at the roots of a tree; dry it and keep it in a cloth bag to offer at a river or temple on the next trip to India; or immerse it in local water only after checking local rules and asking the local Hindu temple, which may have its own arrangements.
Can girls have a mundan?
Yes. The Ashvalayana Grihya Sutra 1.17.19 states that for a girl the rite is performed “only (without the Mantras)” — the same act, without the recited verses — so a daughter’s chudakarana is recognised in the text itself. The Paraskara Grihya Sutra 2.1 describes the rite only for a son and does not mention daughters separately. Today many Hindu families perform a full mundan for daughters exactly as for sons, while others cut only a lock or a little hair as a token. Both are accepted living traditions, and families usually follow their own custom. The texts do not exclude daughters from this samskara.
How do you do mundan at home?
A simple home mundan follows this order: choose the day by family custom and an auspicious date, preferably in the morning; set up a small altar with a cloth-covered stool, Ganesha, a kalash, a lamp, roli, rice and flowers; do the sankalp and Ganesh puja, with an optional small havan; the father or another relative by family custom cuts the first lock with scissors; a barber or experienced relative shaves the head; the hair is collected on a white cloth, leaf or dough ball; then a lukewarm bath, new clothes, blessings, a gift for the barber and a family meal. The Paraskara Grihya Sutra 2.1.21 tells the barber, “Without wounding him, shave him” — so a new, clean blade and two adults gently holding the child are part of the rite.
How should you care for a baby’s scalp after mundan?
No Grihya Sutra gives an instruction about what to apply after the shave; turmeric, sandalwood, curd or oil are family traditions. Basic care: keep the head covered from sun and cold with a soft cotton or wool cap; give a gentle lukewarm bath for the first few days without scrubbing; keep the child’s nails short to limit scratching; and rinse any small nick with clean water and keep it dry. If you want to use turmeric or sandalwood paste, try a small patch first. See a doctor if there is redness, swelling, pus or persistent itching, and ask your paediatrician before applying anything if your child has eczema or sensitive skin.

Sources and cautions: the scriptural references were opened and checked — the Paraskara Grihya Sutra 2.1 (one year or before the third year ends; “without wounding him, shave him”; hair hidden in a cow-stable, pond or near water) and the Ashvalayana Grihya Sutra 1.17 (third year or family custom; hair handed to the mother; the rite without mantras for a girl), both translated by Hermann Oldenberg, and the Manusmriti 2.35 with Medhatithi’s commentary, translated by Ganganatha Jha — all courtesy of wisdomlib.org. The point on hair thickness is courtesy of the Mayo Clinic. Three things should be said plainly. First, we did not find the womb-impurity, past-life, cooling or teething explanations, the fifth or seventh year, or any after-shave paste in these three texts; they come from family custom and later tradition. Second, no oil, cream or product is recommended here; take any decision about your child’s skin or health with your paediatrician. Third, “not found” does not mean “does not exist”; it is an honest report of a search.
