Baby's hair seem to be getting lesser and lesser

My baby is currently around 6months old. I noticed that she seemed to have lesser hair than when she was born. During birth, i can at least see hair on her head, now she still has hair, but barely any. Googled it and it seemed normal for babies' hair to fall,but that doesn't happen to my first born.. So i'm like 😅... Any mummies out there observing the same with their babies too?
