Scalp Psoriasis — The Real Reason Nothing Has Worked, And What Finally Does
The cream isn't failing because your body stopped responding to it.
It's failing because it was never designed to fix what's actually breaking.
You've tried the betamethasone. The stronger formulations. The medicated shampoos that smell like a building site. You've been back to the GP, got a different prescription, watched it work for two weeks, and then watched it stop.
You've probably assumed this is just how psoriasis works. That you need to manage it indefinitely. That some weeks are better and some weeks are worse and there's nothing you can do about that pattern.
You were told wrong.
The pattern has a cause. And once you understand the cause, the solution becomes obvious — and it isn't a stronger steroid.
The Fix Is Simpler Than You've Been Told — But It's Not What You've Been Given
Your scalp has a protective barrier. A layer of proteins and lipids that holds skin cells together, keeps moisture in, and keeps triggers out. In healthy skin, this barrier is intact. In scalp psoriasis, it's severely compromised.
There are microscopic gaps throughout the surface. Irritants pour in through the gaps. Your immune system detects the breach and fires. Skin cells accelerate to try to patch the damage. Plaques form. Scale builds up on top.
When you apply a steroid cream, you suppress that immune response. Temporarily. The alarm goes quiet.
But the gaps are still there.
The triggers are still getting through. The moment you stop the cream, the immune system overcompensates — comes back harder. So you apply more. Over time, the steroid progressively thins the scalp skin, weakening the barrier further, lowering your threshold for a flare.
That's why your triggers keep multiplying. Why the dry shampoo you used for years suddenly causes a flare. Why stress goes straight to your scalp now when it didn't used to.
Close the barrier and the inflammation stops being triggered. That's the whole job. Not another cream that rings in your scalp for two weeks. Seal the gaps. Feed the fresh skin underneath. Let your barrier rebuild.
Suppress the alarm, and it comes back. Fix the gaps, and it stops.
Why Nothing Has Worked
They all have the same problem: they address the symptom on the surface instead of the barrier dysfunction causing it. None of them can reach the part that's actually broken.
You can't stop a flare cycle you can't even get to.
But Here's Where Most People With Psoriasis Get Burned
By the time most people find something that actually works, they've already been put through the cycle too many times to count.
The steroid creams that worked for a month and then stopped. The stronger formulation that worked for two weeks. The medicated shampoo that stripped your hair dry. The GP appointment where you left with another prescription and no explanation. Each one either did nothing, or helped for a fortnight, or cost you in a different way.
So by now you're not just dealing with psoriasis. You're worn down, a little out of pocket, and quietly scared the next thing will let you down too.
"I stopped telling my GP it was getting worse. I knew what she'd say. Another cream. I'd started to accept this was just my life now."
— Sarah M., London · Verified Derval CustomerHere's what matters: it was never that you failed. Every treatment you've tried was designed to suppress the symptom. None of them was ever going to repair the barrier that's breaking.
You weren't the problem. You were handed the wrong fix.
Finally — A Woman Who Refused to Keep Cycling Through Creams
"I'd had scalp psoriasis for six years. For the last three of them, the steroid cream had basically stopped working. I was using it every other day just to keep the itch manageable. My dermatologist said I could try a stronger formulation. I tried it. Same story — two weeks, then back to baseline."
"By that point I'd stopped wearing dark clothes. I kept my hair positioned a certain way at all times. I did a shoulder check before I sat anywhere with bright lighting. I didn't realise how much energy that was taking until I tried to think of the last time I hadn't thought about it."
"I couldn't remember."
"I found Derval after reading about copper peptides in a forum. I didn't expect it to work. I'd stopped expecting anything to work. Six drops at night, massage in, leave it. No smell. Nothing on the pillow in the morning."
"Week two, the nightly itch eased. Week four, I noticed I'd stopped doing the shoulder check — not because I'd decided to, but because I didn't need to. Week eight, I wore a black top to a work dinner and sat under overhead lights all evening without thinking about it once."
"I only noticed on the way home."
Clean Enough To Actually Trust
After everything scalp psoriasis has already taken from you, the last thing you need is a treatment that creates new problems on top of it. Here's what Derval doesn't contain:
Formulated for Scalp Psoriasis — Not Generic Skin Care
The hero compound — GHK-Cu (copper tripeptide-1) at 2% — directly reduces the pro-inflammatory cytokines TNF-α and IL-6 at the tissue level. These are the specific pathways driving psoriasis activity. Not suppressing the immune response globally. Targeting the exact proteins responsible.
At the same time, GHK-Cu stimulates your skin's own barrier repair mechanisms — triggering production of the structural proteins and lipids that seal the gaps between skin cells. It doesn't turn down the alarm. It starts fixing what triggered it.
Supporting it: Niacinamide to reduce redness and strengthen the barrier. Panthenol to deeply hydrate and reduce itch. Salicylic acid at 0.5% to gently lift scale buildup and clear the path for GHK-Cu to reach the follicle level. Hyaluronic acid to lock moisture into scalp tissue. Allantoin to accelerate cell renewal and soothe irritated tissue.
Every ingredient chosen for a specific reason. Nothing added for show.

- GHK-Cu 2% — targets the barrier at source
- Steroid-free · coal tar free · fragrance-free
- Leave-in — six drops at night, no rinse
- 94% of users saw reduced irritation in 4 weeks

Oh — I Almost Forgot.
It's As Easy As Six Drops Before Bed
Part your hair. Apply 6–8 drops directly to the affected areas. Massage in for 60 seconds. Leave overnight — no rinse, no residue, no smell. Here's how it went for Sarah:
"I just wish someone had told me two years ago. It was never a tolerance issue. The steroid was never going to fix what was broken. That could have been sorted the whole time."
