The head scale at the fontanelle needs to be cleaned in time. Usually, head scale is a normal phenomenon in infants with a fast metabolism, where the oil secreted from the scalp and the dirt on the skin surface mix to form. However, it may also be a clinical symptom of eczema. When eczema appears in infants, in addition to erythematous papules, it may also appear as more secretions due to infant allergies, which may solidify into head scale after a long time and affect the growth of local hair. Since infants also have a lot of dirt on their heads, once the local scalp is scratched or rubbed, it will not only affect the treatment of head trauma, but also easily bring the local dirt into the bloodstream, causing local bacterial infection. In addition, because the head dirt is attached to the fontanelle, it will also limit the contraction and cushioning function of the fontanelle. At the same time, the fontanelle is hidden by the head, so it is difficult for parents and doctors to judge the health of the baby by observing the condition of the fontanelle, so appropriate methods should be taken to help the baby clean up the head scale. If the fontanelle is not too much, it can be softened by using olive oil or baby lotion, and after softening, the baby can be wiped off with a warm towel. If it is caused by allergy, you should seek medical attention to clarify the allergen and remove the allergic substance, then use medication to relieve the head scale under the guidance of the doctor.
