Why do babies lose hair?

A fetus begins to grow hair in the first trimester. But whether a child is born with a layer of fluff or a lot of hair, it is all lost later. In fact, hair loss simply means that the infant is making a major adjustment to life outside of the womb.

On the head of an adult, each hair goes through a phase as it grows.

Why do babies lose hair?
Not many people know why a newborn baby has a lot of hair at birth but then it also falls out very quickly.

“There are major hormonal changes that happen in babies’ bodies after they’re born. This can cause all of their hairs to step,” explains Sage Timberline, a pediatrician at the University of California. into the resting phase at the same time. That means all the baby’s hair can fall out at once.”

Both mother and baby experience huge hormonal changes during labor, which are essential for a successful delivery. Induction of labor alerts the baby’s body to start producing hormones that are vital for life outside the womb. Certain hormones help the baby’s arteries and veins develop, ensuring the organs receive ample blood during labor and after the umbilical cord is cut, Timberline says.

A hormone called cortisol , helps babies’ lungs mature, allowing them to take their first breaths. It also helps the baby’s body produce its own energy and heat. In adults, cortisol plays a role in a wide range of physiological functions, from regulating your metabolism to triggering your responses.

Stress triggers the production of cortisol, which fuels the developmental changes important for survival and away from nonessential functions like hair growth.

After birth, all the baby’s hair remains in the resting phase until more resources are available. Hair usually begins to fall out at 8 to 12 weeks of age and begins to grow back around 3 to 7 months. But it was not until about 2 years old that thick hair appeared. The specific duration and pattern of hair loss and growth depends on a number of factors such as gender, ethnicity, genetics, delivery conditions (premature, early or late, or cesarean delivery), and your child’s nutrition. little.

And actually what you may have heard about shaving a baby’s head to allow the hair to grow back thicker is not true. The ends of the baby’s hair are tapered, cutting them only makes them shorter.
