Chronic Scalp Itch. Not Seb. Dermatitis. Please help

@cb314 - scalp psoriasis …?

Do you lichen? There are 4types of it And I have three. I have itching as well and have had for decades. Have you had skin testing done for chemical chemicals and foods like egg whites that could foam up and is used in many products. I’m very sensitive to egg whites and they are in shampoo, toothpaste soap.
It could be your shampoo you’re using also your water. I had to put a whole house filter as well as a softener in my house due to itching and sores throughout my body.
If you have skin testing done, they should check you for the chemicals they put in the water to make it safe to use.
I do have a prescription and it’s a steroid that I put in my hair every day and that does help.
I wish you the best and figuring this all out it’s not easy you take care

@minnesota10 Thank you for responding. I'm not sure about lichen because I have no obvious signs like scale, plaque, or redness. The skin testing is a good idea;Maybe I should see an allergist for that. I washed my hair with bottle water for a week; no change.

@rashida Thank you for the response. At this point I wish it was psoriasis because at least I would know what it is. I don't have any tell tale signs of psoriasis though. I can't believe my dermatologist can't help me; it's so frustrating.

I’m questioning if it is your shampoo, Condition, Hairspray, Gel, Or anything else you put on your head that is causing the itching
There is also one more thing. I have to wear hats right now if I’m outside because I have photodermatitis Which means I’m allergic to the sun. And this year with all the smoke and other things that have been going on my head itches like crazy.
If I wear a hat every time I go out it’s better.
I also am having issues with my arms and hands itching because of the sun and so I have to wear lightweight sheer shirt that I could take off until probably September.
I wish you the best

Good suggestions. You can have seb derm that doesn’t look obvious.
The Derm scope would pick up on scales.
Patch testing for chemicals affecting the skin is usually done by dermatologists if they have an interest in allergies. They may not think
of it if there is no outward signs of irritation but the problem can exist
without being apparent.
The internal causes may require some blood testing to eliminate deficiencies
or metabolic problems.
There are other treatments you can try. I have subtle scalp / ear psoriasis and
and do well rotating several shampoos with different active ingredients.
Ketoconazole works best if massaged in with a baby hair brush and lather
left on during shower.

@seniormed I've got to get some blood work done for sure as well as skin test. I'm also making some lifestyle changes.

Thanks for replying.

@minnesota10 Bummer about all that smoke polluted air coming down from Canada; i hope it clears up soon. I try to stay out of the sun during peak uv times to limit any more sun damage as I get older. As far as scalp itch is concerned, i'm going no products or shampoo for a few days to see if anything changes.

My dermatoligist recommended a special shampoo. It's called Nizoral and keeps the itches away!
