It's perfectly normal for your baby to have some hair on their ears. This is often leftover lanugo.
What is Lanugo?
Before birth, babies are covered in a fine, downy hair called lanugo. This hair helps regulate their temperature in the womb. Most of the lanugo sheds before birth, but some can remain, especially on areas like the ears, the top of the back, and the base of the neck. This remaining lanugo is often described as peach-fuzz-like. Cleveland Clinic explains that this is completely normal and nothing to worry about. A baby born prematurely may retain more lanugo than a full-term baby because its shedding isn't fully completed. Happiest Baby further supports this, emphasizing that this is normal and should not be a cause for concern. A midwife's explanation from a Reddit post confirms this: most lanugo falls out before birth, but some remnants are common. Reddit
When to be Concerned
While hairy ears due to residual lanugo are typically harmless, in rare cases, excessive hair growth could be associated with certain medical conditions. One example is Cantú syndrome, characterized by excessive hair growth on the scalp, forehead, and cheeks.

Key Takeaways
- Lanugo: Most hair on a baby's ears is leftover lanugo, a fine, downy hair present before birth.
- Normal Variation: The amount of lanugo remaining varies from baby to baby.
- Premature Babies: Premature babies might have more lanugo than full-term babies.
- Rare Conditions: Excessive hair growth in other areas in conjunction with other symptoms might warrant a medical evaluation, but isolated hairy ears are usually normal.
