Not many people know why babies, although a lot of hair at birth but then also fall out very quickly.

Sage Timberline, a pediatrician at the University of California, explains: "There are major hormonal changes that occur in a baby's body after they are born. This can cause all of their hair to walk. at the same time resting stage means that all babies 'hair can fall out at the same time.'

Both mothers and babies experience huge hormonal changes during labor, which is essential for a successful birth. Induction of labor warns the baby's body to begin producing hormones that are important for life outside the uterus. Some hormones help the baby's arteries and veins grow, ensuring organs receive abundant blood during labor and after cutting the umbilical cord, Timberline said.

A hormone, called cortisol , helps the newborn's lungs mature, allowing them to perform their first breath. It also helps the baby's body produce its own energy and heat. In adults, cortisol plays a role in a variety of physiological functions, from regulating metabolism to triggering your reaction.

Stress activates cortisol production, which helps to fuel vital developmental changes for survival and away from unimportant functions like hair growth.

After birth, all babies' hair is still in the resting period until more resources are available. Hair usually begins to fall out at 8 to 12 weeks of age and begins to regrow around 3 to 7 months. But it took about 2 years for thick hair to appear. The specific time and model of hair loss and growth depends on a number of factors such as gender, ethnicity, genetics, birth conditions (premature, early or late birth or cesarean section) and nutrition. little.
