If you've lived with scalp psoriasis, you know the cycle. The itch that wakes you at 3am. The flakes on every dark shirt. The steroid creams that work for a week before your scalp rebounds worse than before. The coal tar shampoo that smells so strong your colleagues notice. And the sinking feeling every time you try something new that this probably won't work either.
Over 900,000 people in the UK live with psoriasis — and scalp psoriasis affects roughly half of them. Most are managing symptoms with NHS treatments that haven't meaningfully changed in decades. But quietly, a different solution has been spreading through online communities, dermatology waiting rooms, and word-of-mouth across the UK. Here are 10 reasons why 10,000+ sufferers are finally finding the relief they stopped believing existed.
Most scalp psoriasis treatments are suppression tools. Steroid creams dampen the immune response that causes inflammation. Coal tar shampoos slow skin cell turnover. They work — but only while you're using them. The moment you stop, the scalp rebounds, often worse than before.
Derval works differently. Its hero ingredient — GHK-Cu (copper tripeptide-1) — reduces pro-inflammatory cytokines TNF-α and IL-6 at the tissue level. These are the same cytokine pathways directly responsible for the chronic inflammation that drives psoriasis plaques.
This is the difference between treating the fire and treating the source of the smoke.
If you've used topical corticosteroids for scalp psoriasis, you'll know the dread of the rebound. You apply the cream, the scalp calms down, you stop using it, and within days the inflammation comes back — sometimes harder than before. This is called steroid rebound, and it traps thousands of people in a dependency cycle they never asked for.
"I'd been on betamethasone for 3 years. Every time I tried to come off it, my scalp went haywire. I started using Derval as a bridge and within 6 weeks I was completely off the steroids. I haven't gone back."
— James T., Leeds · Verified Derval CustomerDerval contains zero steroids. It's safe for daily, long-term use. There's no rebound, no dependency, and no ceiling on how long you can use it. For people who've been caught in the steroid cycle for years, this alone is life-changing.
Coal tar has been used for scalp psoriasis for over 100 years. It works. It also smells like a building site, stains pillowcases, and announces your condition to anyone within two metres of you. For many people, the social cost of coal tar is almost as bad as the psoriasis itself.
Derval is a lightweight, clear, fragrance-free serum. It applies in seconds, absorbs completely, and leaves no residue, no smell, and no trace on bedding. You can use it at night and nobody — not your partner, not your colleagues — will ever know you're treating anything.
Most copper peptide products on the market contain between 0.1% and 0.5% GHK-Cu. This is enough to show some anti-aging effects on facial skin — but nowhere near sufficient to meaningfully impact chronic scalp inflammation.
Derval is formulated at 2% GHK-Cu — a concentration specifically chosen because the scalp's thicker tissue requires a higher dose to penetrate to the follicle level where inflammation originates. This isn't a skincare product repurposed for the scalp. It's built from the ground up for exactly this problem.
One of the least-discussed aspects of scalp psoriasis is the broken skin barrier. The rapid skin cell turnover characteristic of psoriasis disrupts the scalp's protective barrier, making it more reactive to triggers — stress, weather changes, certain products — and more prone to repeat flare-ups.
Derval's formula includes GHK-Cu, panthenol, and hyaluronic acid — all working together to rebuild the scalp's protective barrier. As the barrier strengthens over weeks of use, flare-ups become less frequent, less severe, and shorter in duration. Most users report that by month 3, they're experiencing the longest flare-free stretches of their life.
- GHK-Cu stimulates collagen and barrier protein synthesis
- Panthenol (Pro-Vitamin B5) deeply hydrates and soothes
- Hyaluronic Acid locks moisture into scalp tissue
- Allantoin accelerates cell renewal and healing
A referral to a NHS dermatologist for scalp psoriasis currently takes an average of 18–24 weeks in most areas of England. For someone in the middle of a severe flare — waking up at night, unable to concentrate, avoiding social situations — that wait is almost unbearable.
Derval ships next-day across the UK. You can order tonight and have it tomorrow morning. For the hundreds of thousands of people on NHS waiting lists who need something to help now, that matters enormously.
"I was told 5 months for a dermatology appointment. I couldn't wait that long. Derval arrived the next morning and within 10 days I could actually sleep through the night again."
— Priya K., Birmingham · Verified Derval CustomerScalp psoriasis doesn't just affect the skin. The chronic inflammation, the steroid treatments, the coal tar shampoos — all of these take a toll on the hair follicle. Many long-term psoriasis sufferers experience thinning, brittleness, and increased shedding on top of everything else.
GHK-Cu has one of the most well-studied track records in hair science. At the follicle level, it stimulates hair growth signalling, increases follicle size, and extends the growth phase of the hair cycle. Calming the scalp with Derval doesn't come at the cost of your hair — it actively benefits it.
The people most sceptical of Derval are usually the ones who've been managing scalp psoriasis for the longest. They've tried it all — every prescription, every "natural" remedy, every forum recommendation. Their bar is very high, and their hope is very low.
Which is exactly why their reviews carry so much weight.
We know what it's like to spend money on yet another product that doesn't deliver. Which is why Derval comes with a full 90-day money-back guarantee. Not 30 days. Not 60 days. 90 days — because we know that GHK-Cu works progressively, and we want you to have enough time to experience the full effect.

This is the one that isn't about science or formulation or concentration percentages. It's about the life you've been putting on hold while your scalp dictates your choices.
The dark clothes you wear so the flakes don't show. The events you've left early because the itch became unbearable. The holidays you've avoided because you didn't want to be seen on a beach. The relationships affected by the self-consciousness that comes with a visible skin condition.
"I started wearing my hair down again. That's it. That's the review. After 11 years of tying it back to hide my scalp, I wore my hair down to a work event and nobody stared. I cried in the car on the way home."
— Sarah M., London · Verified Derval Customer
Scalp psoriasis takes enough from you. A serum that actually addresses the inflammation at the cytokine level, rebuilds your barrier, doesn't smell, works overnight, and ships to your door tomorrow shouldn't be a luxury. It should be the baseline.
That's what Derval is built to be.
