My son fell about 5 months ago and cut his head and had three stitches. He wasn't overly traumatized by it. After this, I notices slight hair loss. This hair loss has continued since. It's not noticeable to others, but as the mother, I notice the hair falling out. It's not a whole lot but more than normal. He is a very healthy boy and always has been, with no symptoms of anything adverse. He does still have cradle cap from when he was a baby, that I'm treating with tea-tree cream. Do you have any advice as to what could be causing this hair loss? Like I said, it's not severe, but it's been going on for a while now. Thanks for any advice you have.
