Lanugo is the first hair produced by the fetal hair follicles, and it usually sheds before birth.
Functions: Why It's There

- After Birth: Within a few weeks for some.
- Persistent Lanugo: Rare but can happen.
Should You Be Concerned?
- Normal Phenomenon: Usually no cause for concern.
- Late Shedding: May require medical evaluation.
