Whether your baby loses a few tufts of hair here and there or goes completely bald, it’s nothing to worry about. The reason most adults immediately jump to the worst conclusion is that sudden hair loss (telogen effluvium) later on in life is usually a symptom of a larger problem. Again, that’s often not the case for infants. The fluctuating hormones that are likely the trigger for their hair loss are a natural part of the growth process.
