Does shaving a baby's head really thicken hair?

The Mundan Myth

Here's the short, honest answer, and one tip most people miss.

Verdict: Depends

Here's the verdict: shaving a baby's head doesn't make hair grow back thicker, darker, or faster. Follicles are set before birth, and a razor only cuts hair at the surface. Muslim families shave on the seventh day for aqiqah; Hindu families do mundan sanskar in the first or third year. Meaningful customs, we're only checking the thickness belief, and it's a myth.

Why it looks thicker

A newborn's hair is often patchy, fine, and uneven. Some strands are long, some have fallen out, and the back of the head might be bald from lying on it. Shave all that off, and a few weeks later you see an even, dense fuzz. To the eye, that's thicker hair. There's also timing, most babies shed their first hair anyway, and the second growth is often coarser and darker. It's not the razor, just nature.

Genes decide thickness

Think of each follicle as a tiny pot under the skin. Hair grows out of it like a plant. A razor trims the plant at soil level, it never touches the pot. The number of pots, their size, and colour are set by genes, and a baby is born with the full set. What changes thickness over time? Age, mainly. Over the first few years, many follicles start producing a thicker, darker strand. No razor changes the pot.

The razor and the pot

This is the image that stuck with me. The razor trims the plant at soil level, it never touches the pot. Every time you shave a baby's head, you're just trimming the grass. The pot underneath, the follicle, stays exactly the same. That's why the shave can't change thickness, darkness, or speed of growth. It's a lovely, simple way to understand what's happening under the skin.

Three shaves won't help

Some families repeat the shave, believing each round improves the hair. But each round restarts the same follicles at the same thickness. Repeated shaving adds no benefit, just more chances for nicks, razor bumps, and irritated skin on a scalp thinner than an adult's. Same goes for rubbing oils into a freshly shaved scalp to feed the roots. Oil can soften dry skin, but it doesn't reach the follicle. If you're shaving for thickness, you're shaving for nothing.

If you shave, go gentle

Many parents shave for reasons that have nothing to do with thickness, and that's their choice. A few steps make it gentler. Pick clippers over a blade, an electric clipper with a guard leaves a few millimetres and almost never nicks. Choose a calm moment: a fed, sleepy baby moves less, and two adults help, one holds and soothes, one cuts. Wet the hair with plain warm water first, and test it on your inner wrist. Go with the direction of growth.

Fever threshold for newborns

Here's a number worth knowing. If your baby is under three months old with a temperature of 38 degrees Celsius or more, that's a sign to call a doctor or health visitor. It's a threshold that sounds small but matters for a tiny baby. Also see a doctor if a nick keeps bleeding after ten minutes of firm pressure, or if the scalp shows spreading redness, swelling, pus, or weeping crusts.

Red flags to watch for

There are a few other signs that deserve a proper look. If bald patches appear in a child who previously had full hair, that's worth checking. Patchy hair loss in an older baby, scaly round patches, or hair that breaks off can point to a skin condition that needs a doctor's eye. These aren't about the shave, they're signs something else might be going on. If you're unsure, a health visitor is a great first stop.

Gentle care wins

So what actually helps a baby's scalp and hair? Gentle care, not force. Wash with plain water, or a mild baby wash if needed, and dry softly. If yellow, greasy scales build up, that's usually cradle cap, common and harmless. Don't pick at the crusts. If you like a daily malish the way nani did it, choose the oil carefully. Coconut oil or an emollient works well for loosening scales, but olive oil may not suit baby skin, and peanut oil is best avoided. Keep it gentle.

The one thing to bring

Now, the one thing to remember if you're getting the shave done at a barber. Bring your own clean clipper, or a new sealed blade, plus a soft towel from home. Shared razors can carry infection between customers, and most barbers are happy to use what you bring. It's a tiny step that makes a big difference for a baby's sensitive scalp. And it's the simplest way to keep that ritual safe.
