Whitening of the nail plate in children is most often seen in the form of dots, known as punctate white nails, and is mostly associated with minor trauma during play; in addition, linear white nails can also occur. It is rare for the whole nail plate to become white and is a congenital white nail condition. Most nail plate delamination is related to the low water content of the nail plate, so topical moisturisers should be used to protect the nail plate. In addition, if your child has nail chewing habits, it is important to correct them, pay attention to nutritional balance and try to avoid picky eating.
