Baby feathers how long does it take to grow on top of head?

Baby feathers, also known as vellus hair, are present on the head and body of newborns and infants. They are typically fine, soft, and barely visible. The growth rate of baby feathers can vary from person to person, but they usually start to shed within a few weeks to months after birth. Some babies may shed all of their baby feathers within a few months, while others may have a few remaining until they are a few years old. The shedding process is natural and does not require any special treatment.
