Had this problem for a couple of months. DH has looked at my scalp as my first thought was perhaps I had picked up something nasty. No sign of anything so when we visited my daughter who is a nurse she had a good look. She said it looked like ecsma and to use something like olive oil or coconut oil to massage the scalp before washing hair.
I have done this and at first my head felt better but as soon as my head rested on something it started to feel sore and itchy. Has anyone else had a problem like this who can help. I don’t use any hair colouring products, perms etc. My shampoo is the same one I have used for a about three years and is a mild one containing natural products and has never given me any trouble. I have had a fair amount of stress and worry which I have tried to curb but would so welcome any advice.
