Lanugo: The Fuzzy Coat of Newborns


Lanugo: Nature's First Blanket

Lanugo is the fine, soft hair that covers a fetus and newborn. While it may look unusual, it serves essential functions.

What is Lanugo?

Lanugo is the first hair produced by the fetal hair follicles, and it usually sheds before birth.

Functions: Why It's There

  1. Temperature Regulation: Helps to keep the fetus warm.
  2. Protection: Acts as a barrier against friction in the womb.
  3. Sensory Function: May help the fetus sense touch.

When Does It Disappear?

  1. Before Birth: For most babies.
  2. After Birth: Within a few weeks for some.
  3. Persistent Lanugo: Rare but can happen.


Should You Be Concerned?

  1. Normal Phenomenon: Usually no cause for concern.
  2. Late Shedding: May require medical evaluation.
  3. Associated Conditions: Like eating disorders in older children.
