My son has had hair loss since he was an infant. Soon thereafter we found out it was also effecting his finger and toenails. Does anyone know where to find further information about just the nails? He has adjusted to not having the the hair and no eyebrows or lashes but the nails he is wanting to do something with. And I hate to deny him but I want to be safe and make sure I don't cause injury by putting something on his nails including lotions.
