Very dry flaky scalp

I was under a Trichologist for some time.
It definitely sounds like seborrheic dermatitis ( round the ears and hair line are classic symptoms.
My Trichologist told me I must wash my hair every day. Think of this like a fungus, it can grow at an alarming rate.
This is what I use.

Thanks for all replies I will try and get a gp appointment to get it checked out.

Phillip Kingsley do a good range of products for flaky itchy scalps. Not cheap but very effective. These can be bought online. Perhaps worth a try.

It could be Seborrheic Dermatitis, I’ve had this for many years and my GP said it can’t be cured but I managed to control it mostly to a small patch on the nape of my neck. I tried every shampoo (baby shampoo made it much worse) oil and cream but nothing really worked. Now I buy Polytar shampoo and at first used it twice a week for a month and as it had spread all over my head and now it’s under control I use it once a fortnight and my usual shampoo in between. It’s still there on the back of my head but is much less itchy and flaky.
Maybe see your GP for a diagnosis.

By the way, I am prone to psoriasis and use Exorex (the lotion version) at night as soon as it flares up again - washing my hair in the morning with a mild non-irritating shampoo.

I do think it's best to know what you are dealing with though.

It could be psoriasis. I suggest you have a GP take a look if you can.
Polytar is of course used for psoriasis - and is available on prescription (or certainly used to be).

I hope you soon find something to get this under control.

Have you tried Polytar eczema shampoo. My grandson has x linked ichthiosis and consequently has very dry flaky skin. He uses this.
You could also try Nizoral anti dandruff shampoo.
