In fact, without any melanin, hair would appear white. Although gray hair may be normal for an adult, it might not seem so typical for a child. However, it is possible for children of all ages to grow a few gray hairs of their own.
genetics and inheritance are a cause
some medical conditions in the childhood may contribute to the problem such as skin disorders like vitiligo, tuberous sclerosis, neurofibromatosis have been indicated to induce the loss of hair pigmentation. but their will be other causes too.
Another cause of early graying is an overactive or underactive thyroid condition such as Grave's disease or Hashimoto's disease.
vitamin b12 dificiency also might cause gray hair in childhood you can check for its level through a blood test
stress on the genes from ultraviolet light and radiation---may mutate hair cells, triggering early signs of graying.
many cause then may contribute to this condition ,if there is underlying medical condition the condition will be treated after treating the cause ,if it is vitamin b12 deficiency then correcting it will treat the condition ,if it is genetics or inheritance and the grey hair are bothering you you can dye color your hair
