Can newborns have their heads shaved bald?

Whether or not to shave a newborn's head should be determined based on the ambient temperature, in order to avoid causing discomfort.

If the newborn is in a relatively warm environment, shaving the head is generally acceptable. Thick hair can lead to excessive sweating and increase the risk of heat rash; shaving helps prevent such rashes and promotes sweat evaporation. However, after shaving, care must be taken to avoid direct sun exposure, which could cause sunburn. Conversely, if the newborn is in a cooler environment, shaving the head is usually not recommended, as hair provides protection and insulation. Removing it may leave the baby vulnerable to colds or chills, which could negatively affect health; therefore, shaving should be avoided under these conditions.

When shaving a newborn's head, it's important to use a dedicated baby hair clipper, as improper tools may injure the scalp. Additionally, after shaving, the scalp should be cleaned promptly to remove any loose hairs that might irritate the baby.
