Medically reviewed by pediatrician Alexandra Zglavosiy

Hair loss in babies is normal. In the first few months, hair often thins due to hormonal changes after birth, and new hair typically starts growing around 6 months. To help prevent bald spots, change your baby’s sleep position regularly and choose lightweight hats. See a doctor if there’s redness, flaking, itching, or if hair doesn’t grow back after age one.

What’s Inside

💡

Quick takeaways

Hair loss is normal. Most babies lose some hair in the first 3–6 months due to a drop in maternal hormones after birth. New hair usually starts to grow between 6–12 months and may be darker or thicker.

Warning signs: round bald spots with clear edges, redness, flaking or itching of the scalp, or if hair doesn’t grow back after one year. In these cases, consult your pediatrician.

To prevent bald spots: change your baby’s position during sleep and play more often, and choose loose hats made from breathable fabrics.

Why do babies lose hair

Hair loss in infants is linked to hormonal changes. While in the womb, a baby has high hormone levels, which promote active hair growth. After birth, hormone levels drop, and some hair falls out, making way for new, stronger hair.

  • First signs of hair loss can appear as early as 1–2 months old.
  • By 3–6 months, hair loss may be most noticeable-some babies develop bald spots, especially on the back of the head.
  • After 6 months, new hair begins to grow, which may differ in color and texture from the hair at birth.

How to care for your baby’s hair

  • Use gentle baby shampoos without harsh surfactants or fragrances.
  • Don’t wash your baby’s hair too often-2–3 times a week is enough.
  • Massage the head gently to improve blood flow.
  • Use soft brushes with natural bristles to avoid damaging delicate hair.
  • Avoid tight hats-they can reduce blood flow to the scalp.

When to see a pediatrician

In most cases, newborn hair loss is temporary and doesn’t need treatment. New fuzz or full hair will grow back on its own.

But see your pediatrician if:

  • Hair loss is accompanied by redness, flaking, rashes, or itching-this may be a sign of a skin condition.
  • Hair falls out unevenly, forming round bald spots-this could be due to a fungal infection or autoimmune process (like alopecia).
  • Hair loss continues after one year and new hair does not grow in.

FAQ about Baby Hair

— Can my baby’s hair color and texture change?

Yes, this is normal. The first hair may be thinner and softer, and over time it may become thicker, darker, or even change shade.

— Is hair loss linked to a lack of vitamins?

Rarely. In most cases, it’s a natural process. If your baby eats well (breast milk or formula), vitamin deficiency is unlikely.

— How can I prevent bald spots on the back of the head?

Change your baby’s position during sleep more often so they don’t always lie on the same side or on the back of their head.
