Many moles on the scalp of children are congenital, that is, they are large, dark pigmented moles on the scalp. If it is simply within the scalp, it does not affect the aesthetics or normal hair growth. If the nevus has grown outside the hairline, it may affect the aesthetics of the face. There are also small pigmented moles instead of large ones, which are normal and are the result of an abnormal accumulation of pigment cells. Moles are more likely to grow on the face or head and neck, so it is normal for children to have moles in their scalp. If it is a small mole, it can be left untreated, and if it is a large mole, it can be left untreated if it does not affect the beauty. If a large mole has gone beyond the hairline and affects the beauty of the face, you can go to the plastic surgery department of a regular hospital for examination to see if it can be treated. If you want to treat it, you may need a surgical procedure to remove the nevus beyond the hairline in order to restore the normal skin color.
