Baby Hair Care: Tips for Washing, Brushing and Managing Different Hair Types

Whether your newborn arrives with a full head of hair or the softest peach fuzz, their scalp and hair need a gentle, specific approach — and for many parents it’s uncharted territory, full of questions about how often to wash, what to do about cradle cap, and whether to use any products at all. A baby’s scalp, like the rest of their skin, is a delicate, still-developing organ, and it’s the foundation for healthy hair. The good news is that good baby hair care is mostly about doing less: gentle cleansing, minimal products, and protecting the scalp. Here’s a practical, science-informed routine.

The Biology of Baby Hair

Understanding what you’re caring for makes the routine make sense. Many babies are born with fine, soft body hair called lanugo, usually shed within the first few weeks. The hair present at birth often has a different texture and growth cycle, and it’s common for it to fall out — a normal process called telogen effluvium of the newborn — around 2 to 4 months of age, with the permanent hair growing in a possibly different color and texture. A baby’s scalp also has a higher density of oil (sebaceous) glands than adult skin, which contributes to the waxy scales of cradle cap, while the skin barrier is still maturing, making it prone to dryness and irritation from harsh products. The hair shaft itself is finer and more fragile than an adult’s, so it needs gentle handling to avoid breakage. All of this points to one philosophy: gentle cleansing, minimal intervention, and protecting the scalp barrier.

Washing and Brushing

How often to wash. For most babies, washing the hair and scalp 2–3 times a week is plenty — over-washing dries the scalp, while under-washing lets oil and product build up. You can wet the hair at other baths without shampoo. Use a single, tear-free, fragrance-free baby shampoo or all-in-one baby wash, not adult shampoo (which is formulated for a different pH and oil level).

Technique: hold your baby securely, cradled in your arm over the sink or tub with their neck and head supported. Use a dime-sized drop of shampoo, and gently massage it into the scalp with your fingertips, not nails, in soft circular motions to loosen any flakes without scratching. Rinse thoroughly with lukewarm water, using your hand as a shield over the forehead to keep runoff out of the eyes (a small pitcher helps), then pat — don’t rub — the hair dry with a soft towel.

Brushing: use a soft-bristled baby brush or a wide-toothed, seamless comb (natural bristles are great for distributing scalp oils). Start at the ends to detangle and work up toward the roots, and be gentle around the soft spots (fontanelles). For fine or curly hair, a spritz of plain water or a tiny drop of fragrance-free baby conditioner helps. Brushing stimulates the scalp, spreads natural oils, and can gently loosen cradle-cap scales — and it’s soothing.

Cradle Cap and Dry Scalp

Cradle cap (infantile seborrheic dermatitis) is very common and harmless, caused by overactive oil glands and a yeast called Malassezia. It shows up as thick, yellow, white, or brownish greasy or crusty scales on the scalp, and it’s not itchy or painful for the baby. Importantly, it’s not caused by poor hygiene and doesn’t signal an allergy. To treat it gently at home:

• Apply a small amount of plain oil (mineral, coconut, or olive) to the scales 15–30 minutes before bath time to soften them.
• Gently massage it in, then use a soft brush to lift the softened scales.
• Wash with a mild baby shampoo to remove the oil — you may need to shampoo twice to clear the residue.
• Once dry, brush again to remove loosened flakes, and repeat every few days until it clears.

Don’t pick at the scales, which can irritate or infect the skin. If the rash spreads to the face or body, becomes red and inflamed, weeps fluid, or doesn’t improve with home care, see your pediatrician — they may recommend a medicated shampoo (such as 2% ketoconazole or selenium sulfide), which should only be used under their direction.

A dry, flaky scalp is different — it looks like loose, white, dandruff-like flakes (rather than greasy adherent scales) and often comes from dry air or over-washing. Reduce shampooing to 1–2 times a week, rinse thoroughly, and after bathing you can apply a tiny amount of fragrance-free baby moisturizer to the scalp.

Choosing Products

The baby haircare aisle is overwhelming, but a few principles cut through it. Prefer products that are fragrance-free (the single most important criterion for avoiding irritation), pH-balanced for delicate skin, and built on mild surfactants like decyl glucoside or cocamidopropyl betaine. Avoid fragrance/parfum (a leading cause of contact dermatitis), essential oils (which can sensitize infant skin and airways), harsh sulfates like sodium lauryl sulfate (SLS), and formaldehyde-releasing preservatives like DMDM hydantoin. Styling products are generally unnecessary for infants; if you need one for a special occasion or very curly hair, choose a single fragrance-free, water-based product and use a minuscule amount, skipping hairsprays, alcohol-based gels, and heavy pomades. Our guide to a non-toxic nursery covers reading labels more broadly.

Different Hair Types

• Fine or sparse hair: keep it simple — gentle washing and soft brushing. A hat is great for sun and wind protection.
• Thick or dense hair: make sure shampoo is massaged into the scalp and completely rinsed out to prevent buildup.
• Curly or coily hair: this type is more prone to dryness, so shampoo less often (about once a week) with a gentle cleansing conditioner (co-wash) in between, comb only when hair is damp and conditioned with a wide-toothed comb, and apply a tiny dab of a fragrance-free, lightweight leave-in or oil (like pure jojoba) to damp hair to define curls and lock in moisture.

For every hair type, protect the scalp from sun with a hat, and avoid tight hairstyles like ponytails or braids that pull on the hairline, since they can cause traction alopecia (hair loss).

The First Haircut

There’s no medical need to cut a baby’s hair — it’s a cultural or personal choice. Many families wait until after the first birthday, when a child can sit more steadily, while some do a symbolic snip earlier. If you do it, work at home or choose a salon experienced with babies, bring distractions like toys or snacks, use sharp safe scissors rather than clippers (which can startle), keep it simple (trimming bangs or evening out the ends), and consider saving a lock in a memory book.

When to Call Your Pediatrician

Most scalp and hair issues are benign, but contact your doctor if you notice:

• Bald patches with broken hairs, which can indicate friction or hair-pulling.
• Sudden, complete hair loss beyond normal postnatal shedding.
• A scalp rash that is red, inflamed, weeping, or has pus — possible signs of infection (impetigo or a fungal infection).
• Severe cradle cap that spreads to the face or body or doesn’t respond to treatment.
• Any raised birthmarks or lesions on the scalp that are growing or changing.

The Bottom Line

Caring for your baby’s hair is less about elaborate routines and more about supporting a healthy scalp. A minimalist approach — infrequent washing with a mild, fragrance-free product, gentle brushing, and simple oil-based treatment for cradle cap — nurtures healthy hair without stress or irritation. Whether your baby has wisps or waves, the most important ingredients are your gentle touch and a little patience, and when in doubt, simpler is almost always better.
