Could this be Candida related?

I have a very itchy scalp and thought I maybe just had a little bit of dandruff. My scalp has got worse however and no treatments seem to work, chemical or natural. My ears are also very itchy and a little sore, deep in the canal but there is no great wax problem or anything. Back to my scalp; when I scratch my scalp to relieve the itching, there is residue under my nails, like a greasy build up of flakes? My scalp and ears itch constantly and I've had this condition for quite a while now. Its driving me crazy! Tweet
