Hello and welcome. I'm Dr Chip
If the cortisone cream isn't really working here too well we're probably dealing with a fungal infection lke tinea capitis.
I'd suggest trying Lotrimin cream three times a day for two weeks and if that doesn't clear this up you'll need prescription ketoconazole cream.
Please let me know if you need any more information Mario
