What is this rash? Any ideas what could have caused it

[Tiredallthetimeneedsleep]

Both me and 1 child (9) have this very itchy rash on scalp and neck only. Things we have ruled out. Shampoo/ washing powder/ lice/ scabies / fleas. Dcat elderly so cant get on sofa never mind upstairs.pic attached

Bump?

It is either seborrhoeic dermatitis or an overgrowth of a harmless yeast, Malassezia.

T-gel or Nizoral shampoo. I have been suffering sinc January and nothing is touching mine but the doctor has taken scrapings to see if its something else.

Thank you. Have tried antibiotics ( diagnosis follicalitus )and (eucorax?) cream ( diagnosis dermatitis). Nothing is helping

I'm so sorry about that. I dear mine is the same. It is not fungal but they didn't have enough scrapings to check for other issues.
