I Have Had Severe Itching On My Scalp. When My

I have had severe itching on my scalp. When my hair is parted I can see parts of my scalp is pink.
I do not have lice or dandruff.
I then got itching on my body and it seems the medicine has helped with that but not so much on my scalp
Also I lost my sense of smell about a year ago and my ENT does not seem to know what to do about that.
