Infant head limescale is a dirt consisting of oil secreted from the head and dust in the air, which needs to be treated promptly to avoid harming the health of infants. It can cause itching and other discomfort, and if scratched accidentally, it can easily lead to local breakage and secondary infection. If the scalp is covered with scales for a long time, it will affect the growth and development of the scalp and may lead to the inability of the scalp to perform its physiological functions properly. If the infant’s head scale covers the fontanelle for a long time, it may restrict the stretching function of the fontanelle or lead to the inability to detect the sunken fontanelle or full fontanelle in time. If the baby’s head scale is dry, you can gently wipe it with olive oil, tea seed oil, peanut oil, etc. After the head scale is fully softened, wipe it off with a towel, and then wash it with warm water, and repeat several times to clean the head scale.
