.. could it be crqadle cap even at this late age - a friend reckons it's some kind of fungal condition as most of his scalp is covered in large, thick, greasy flakes. Olive oil and/or dentinox seem to make no difference. He's had it since he was about 9 months and it's getting worse and worse (I naively assumed it was just cradle cap and would get better of its own accord). Has anyone got any advice on whaqt it might be and how to get rid of it - should I go to the doctor with it?
