Baby Hair Care: When to Wash, Which Shampoo to Use, and What to Avoid

Baby Scalp and Hair: More Delicate Than You Realize

A newborn’s scalp is not simply a miniaturized version of an adult’s. The skin barrier of a newborn is significantly more permeable — meaning it absorbs substances more readily and loses water more easily than mature adult skin. The scalp, covered in fine hair follicles and active sebaceous glands, is particularly sensitive. This is why pediatric guidance on hair care for infants is more conservative than many parents expect.

When to First Wash Your Newborn’s Hair

The World Health Organization recommends delaying the first bath — and therefore the first hair wash — for at least 24 hours after birth. This allows the vernix caseosa, the white waxy substance that covers the newborn’s skin at birth, to remain and act as a natural moisturizer and protective barrier during the transition from womb to world.

Once you are home, newborns do not need a daily bath or daily hair wash. The AAP recommends bathing your baby — including shampooing their hair — no more than three times a week during the first year (see the AAP’s bathing and skin care guidance). The standard recommendation from pediatric sources is to wash infant hair 1–3 times per week. Once or twice weekly is plenty for most babies. For water temperature and drowning-prevention rules, read our newborn bath safety guide.

Even if your baby is completely bald, gently cleaning the scalp removes excess oil and dead skin cells — which matter for scalp health even without visible hair.

How Often Should You Wash Baby’s Hair?

The simple guideline: wash your baby’s hair 2–3 times per week at most. Washing more frequently strips natural oils and can dry out the scalp, creating the very problems you are trying to avoid. Washing less frequently, for most babies, is fine unless you notice visible buildup.

Let the scalp guide you rather than the calendar: if the scalp looks slightly greasy or flaky, wash it. If it looks comfortable and clean, skip this session.

Between washes, if your baby spits up or gets messy, a damp warm washcloth over the scalp is entirely sufficient — a full shampoo is not required for minor messes.

Choosing the Right Baby Shampoo

What to Look For

• Tear-free formula: essential for newborns who cannot close their eyes on command.
• Fragrance-free: added fragrances are one of the most common causes of contact dermatitis in infants. Unless specifically formulated as hypoallergenic fragrance, all fragrance in baby shampoos is suspect.
• Free of parabens, sulfates, and dyes: these preservatives and surfactants are unnecessarily harsh for a developing scalp.
• pH-balanced for baby skin: adult and even some ‘natural’ shampoos are formulated for adult scalp pH, which differs from infant scalp pH.
• Labelled for infants or newborns: these formulas undergo specific testing for baby skin.

What to Avoid

• Adult shampoos: always too harsh for infant skin, regardless of how ‘gentle’ the marketing claims.
• Shampoos with strong essential oils: tea tree oil, peppermint, and eucalyptus can be irritating and even toxic at high concentrations in infants.
• Unverified ‘natural’ shampoos: natural does not mean safe or tested. Some natural ingredients — including certain plant oils used routinely on baby skin in some cultures — have been found in research to affect the developing skin barrier. When in doubt, choose a product with a track record of pediatric recommendation.

Cradle Cap: What It Is and How to Manage It

Cradle cap (seborrhoeic dermatitis) is one of the most common scalp conditions in newborns, appearing as yellowish, greasy, flaky scales on the scalp. It looks alarming but is completely benign and resolves on its own in most cases within weeks to months. The NHS cradle cap guidance describes the same gentle approach. For a wider look at baby skin problems, see our common rashes in babies triage guide and the newborn rashes and skin conditions field guide.

Management steps:

• Apply a small amount of natural oil (coconut oil, petroleum jelly, or plain baby oil) to the affected patches and let it sit for 15–20 minutes to soften the scales.
• Gently loosen the flakes with a soft-bristled baby brush — never pick or scratch.
• Shampoo with a gentle baby shampoo to wash away the loosened scales.
• For persistent or severe cradle cap, your pediatrician may recommend a specific shampoo or, in rare cases, a mild antifungal treatment.

Do not use over-the-counter dandruff shampoos (including those containing selenium sulfide or ketoconazole) on infants without specific pediatric guidance — these are not formulated for infant scalps. If the scaly rash spreads into the skin folds, our guide to baby neck rash home remedies explains what to do.

How to Wash Baby’s Hair Safely

Step-by-step technique:

1. Fill a baby tub or sink with a few inches of warm water (test with your wrist — it should feel comfortable, not hot).
2. Support your baby’s head and neck at all times. For newborns, the football hold (baby lying along your forearm, head at your hand) gives good control.
3. Wet the scalp with a small cup or your cupped hand.
4. Apply a coin-sized amount of baby shampoo directly to the scalp and work in with gentle, circular fingertip pressure.
5. Rinse thoroughly by pouring water from behind the head forward — this naturally directs water away from the eyes.
6. Pat dry with a soft towel. Do not rub.

Avoid using a hairdryer on any heat setting on infants. If you must dry the hair quickly, a hairdryer on the cool setting at maximum distance is acceptable, but air drying is strongly preferred.

Oil Massage and Traditional Hair Practices

In many South Asian and Middle Eastern cultures, regular oil massage of the infant’s scalp is standard practice. Coconut oil, almond oil, and other plant oils are applied before bathing and washed off with shampoo. This practice is generally safe and can be comforting for the baby, with the massage itself providing sensory and bonding benefits. Our baby massage techniques guide covers the evidence on oils and gentle strokes.

A few caveats: if oil is applied daily, shampoo every 2–3 days to prevent buildup. Watch for any signs of irritation — some babies are sensitive to specific oils. Research has raised questions about the use of high concentrations of olive oil or sunflower oil on newborn skin (not the same as their well-documented benefits when consumed), so light application is advisable. When in doubt, ask your pediatrician about oils that are appropriate for your baby’s specific skin type.

When Does Newborn Hair Fall Out?

Many babies go through a phase of hair loss at around 3–4 months of age. This is completely normal — it represents the shedding of the fine, lanugo-like hair they were born with, which is replaced by their permanent hair. The new hair may be a completely different texture and color. This process can be alarming for parents who watch a full head of dark hair disappear, but it requires no treatment.

Mild hair loss can also result from lying in one position — typically flat on the back. Tummy time (supervised, while awake) reduces pressure on the back of the head and can help prevent this pattern baldness as well as flat-spot formation.
