Hello there, my son has seen a pediatrician about the spot on his head. She has referred us to a dermatologist in Calgary. Seems like it's exactly what you said, and he sometimes scratches is because he says it itchy. The hair has never grown it there, and it's a light pink, about the size of a quarter. Anyhoo, we always keep it out of the sun and I was told to use hydroquartizone cream for the itch. I guess we'll find out if anything needs to be done when he sees the dermatologist, sometime next year. Thank you.... L
