Some babies are hairy due to the presence of lanugo, a fine, downy hair that covers a fetus in the womb. This is perfectly normal and serves an important purpose.
What is Lanugo?
Lanugo is the first hair produced by a baby's body. It appears around the third month of pregnancy and plays a vital role in:
- Protecting the baby's skin: Lanugo acts as a barrier, shielding delicate skin from amniotic fluid.
- Regulating body temperature: It helps maintain a consistent temperature inside the uterus.
Most babies shed this lanugo before birth, but some retain it, resulting in a hairy appearance at birth. The amount of lanugo varies, with some babies having more than others.
Factors Affecting Lanugo Retention:
- Gestational age: Premature babies are more likely to be born with more lanugo because they haven't had as much time to shed it before birth.
- Genetics: While not fully understood, genetic factors likely influence the amount of lanugo a baby develops and retains.
Is Hairy Baby a Cause for Concern?
No, a hairy baby is generally not a cause for concern. It's a natural occurrence and usually sheds within a few weeks or months after birth. However, if you have any concerns, always consult your pediatrician. There are rare instances where excessive hair growth could be related to other medical conditions but these are exceptional cases.
