The definition of dandruff dandruff is a common skin condition between infants, where fatty and cortical spots appear on the scalp. This condition is usually harmless, and usually appears in the first months of the child's life. This condition is sometimes referred to as "oily dandruff" or "oily dermatitis", and is often considered a result of the increase in sebum production of sebaceous glands in the skin. The reasons for the appearance of dandruff in infants are the multiplicity of causes that lead to the appearance of dandruff on the breast of infants. Among the common causes, there can be genetic factors that play a role in increasing the possibility of their occurrence. Also, the hormonal changes that infants after birth can increase the activity of the sebaceous glands, which contributes to the development of this condition. It is worth noting that dandruff is not a result of poor hygiene, but that infants often develop them even when they are well taken care of. In addition, climate changes or the use of some chemical products for hair may exacerbate the problem. It is important to consult a pediatrician if the dandruff continues or agreed, to ensure appropriate measures to relieve symptoms.
