Washing a newborn’s hair is simpler than most new parents expect. In the early weeks, plain warm water is all you need, and you only have to do it once or twice a week. The key is keeping your baby warm, secure, and comfortable throughout the process.
How Often to Wash a Newborn’s Hair
Newborns don’t produce much oil or sweat, so their hair and scalp stay relatively clean on their own. Once or twice a week is plenty. Washing more frequently than that can dry out a newborn’s delicate scalp, which may actually trigger flaking or irritation rather than prevent it.
For the first few weeks of life, you can wash your baby’s hair during a sponge bath without submerging them in water at all. Once the umbilical cord stump falls off, you can transition to tub baths and incorporate hair washing into that routine.
What You Need Before You Start
Gather everything within arm’s reach before you begin. You should never step away from a baby near water, even for a moment. Here’s what to have ready:
- A basin or baby tub filled with warm water around 100°F (38°C). Test the temperature with your inner wrist or elbow, where your skin is sensitive enough to detect water that’s too hot.
- A soft washcloth for wetting and rinsing.
- A dry, hooded towel to wrap your baby in afterward.
- A gentle cleanser if your baby is past the first few weeks (plain water works fine for very young newborns).
Step by Step: Washing Your Baby’s Hair
There are two common approaches depending on whether your baby is getting a full bath or just a hair wash.
During a Sponge Bath or Standalone Wash
Hold your baby on your lap or on a padded surface, wrapped in a towel to keep them warm. Support their head and neck with one hand, tilting them slightly back over the basin. Wet their hair using a damp washcloth or by gently cupping water over the scalp with your free hand. If you’re using a cleanser, apply a tiny amount, lather gently with your fingertips, then rinse by wiping with the wet cloth. This method keeps water away from the eyes and ears naturally.
During a Tub Bath
If your baby is in a small tub, save the hair for last so they don’t sit with a wet head losing body heat the entire time. Support the back of their head with one hand while you scoop water gently over the scalp with the other. Tilt their head back slightly so water runs toward the back of the head rather than down the face. Use your fingertips to massage the scalp in small, soft circles. Rinse thoroughly by repeating the scooping motion or using a damp cloth to wipe away any cleanser.
Don’t Worry About the Soft Spots
Many parents feel nervous about touching the fontanelles, the soft areas on the top and back of a newborn’s skull where the bones haven’t fully fused yet. These spots are covered by skin and protected underneath by a layer of tough membrane. Normal, gentle washing pressure won’t hurt them. You can massage and clean over the soft spots just as you would the rest of the scalp, as long as you’re using light, careful movements rather than pressing hard.
Choosing a Baby Shampoo
For the first several weeks, plain warm water is enough to keep a newborn’s scalp clean. When you do start using a cleanser, look for one labeled “tear-free.” These shampoos are formulated with a pH close to 7.0, which matches the natural pH of tears. That’s what prevents the stinging, not a numbing agent as some parents worry.
If your baby has sensitive skin or you notice redness, dryness, or irritation after bath time, check the ingredient label for common irritants. Sulfates like sodium lauryl sulfate and sodium laureth sulfate can cause temporary irritation in some babies. Fragrances are another frequent culprit. They may be listed as “fragrance,” “perfume,” “parfum,” or “essential oil blend.” Parabens, used as preservatives in many wash-off products, are easily absorbed through the skin and can trigger reactions in sensitive babies. A fragrance-free, sulfate-free formula with minimal ingredients is the safest starting point.
Drying and Keeping Your Baby Warm
Newborns lose heat rapidly through their heads. As soon as you finish washing, gently pat (don’t rub) the scalp and hair dry with a soft towel. A hooded towel works well because it covers the head immediately while you dry the rest of the body. In cooler rooms, placing a hat or beanie on your baby after drying helps prevent heat loss through evaporation. Make sure any head covering sits snugly but not tightly against the skin.
Never use a hair dryer on a newborn, even on a low setting. Their skin is too thin and sensitive to tolerate directed heat, and the noise can be startling.
Dealing With Cradle Cap
If you notice yellowish, scaly patches on your baby’s scalp, that’s cradle cap. It’s extremely common, harmless, and not caused by poor hygiene. It typically shows up in the first few months and resolves on its own, but you can speed things along during hair washing.
About 30 minutes before bath time, massage a small amount of petroleum jelly, baby oil, or mineral oil into the scaly areas. Use roughly a nickel-sized amount and work it gently into the scalp with your fingertips to loosen the scales from underneath. During the bath, wash the scalp as usual to remove the oil. Afterward, use a soft baby brush, fine-toothed comb, or even a clean soft toothbrush to gently brush away any loosened flakes.
The important thing is not to force it. If the scales don’t lift easily, stop and try again at the next bath. Scraping or picking at stubborn patches can cause redness or even bleeding, which creates an opening for irritation or infection.
Common Mistakes to Avoid
Pouring water directly over a newborn’s face is the most common source of bath-time distress. Always tilt the head back and rinse from front to back so water flows away from the eyes. If your baby cries during hair washing, try using only a damp washcloth to wet and rinse rather than pouring or scooping water.
Using too much product is another frequent mistake. A drop the size of a dime is more than enough for a newborn’s entire head. Excess shampoo is harder to rinse out completely, and residue left on the scalp can cause dryness or irritation between baths. When in doubt, use less, and rinse one extra time.
