Scalp Psoriasis: The End of Visible Flakes on Your Hair

Scalp Psoriasis
In my practice as a Trichologist specializing in scalp disorders, I see one gesture more than any other. It is the “Shoulder Check.” A patient walks in, sits down, and immediately brushes off their shoulders with a nervous hand.
It is a reflexive action born from embarrassment. Scalp Psoriasis is unique among skin conditions because it is impossible to hide easily. Unlike a patch on your leg that can be covered by pants, the scalp sheds onto your collar, your pillow, and your clothes.
Many of my patients come to me thinking they have “severe dandruff” or a hygiene problem. Let me be clear: Psoriasis is not a hygiene issue. It is an autoimmune condition where the skin cells on your head reproduce too quickly. While dandruff is usually oily and yellowish (fungal), scales on the head caused by psoriasis are typically silvery, dry, and often extend past the hairline onto the forehead or behind the ears.
The challenge has always been treatment. Creams are greasy and ruin your hairstyle. Liquid shampoos often contain harsh sulfates that strip the hair shaft. Today, I want to introduce you to a different approach: A therapeutic soap that acts as a solid shampoo, designed to treat the scalp without destroying the hair.
How to Apply Dermabon on the Head for Maximum Results
One of the most common questions I get is, “Can I put bar soap on my hair?”
The answer with Dermabon is a resounding yes. In fact, treating it as a psoriasis shampoo bar is one of its most effective uses.
However, the scalp is a unique environment. It has a high density of hair follicles and sebaceous glands. To treat the plaques effectively without matting your hair, you need a specific technique.
The Trichologist’s Step-by-Step Protocol:
- Saturate: Wet your hair thoroughly with warm (not hot) water. Hot water can trigger inflammation.
- Lather: Do not rub the bar aggressively against long hair, as this can cause tangles. Instead, create a rich lather in your hands or gently rub the bar directly onto the scalp at the roots/parting lines.
- Massage: Use your fingertips (never your fingernails!) to massage the lather into the scalp. Focus on the areas with the thickest plaques.
- The Critical Step: Wait 3 to 5 minutes.
Why the Wait?
Most commercial shampoos are “wash and go.” They are designed to strip grease, not treat disease.
Dermabon is a therapeutic vehicle. The active ingredient needs time to bypass the hair shaft and penetrate the keratinized plaque on the scalp. If you rinse it off immediately, you are washing the medicine down the drain.
Use this time to wash your body or shave.
Technical Fact: Dermabon is formulated to be low-foaming compared to sulfate-heavy shampoos. This is intentional. High foam often indicates harsh detergents. Our formula prioritizes the concentration of the active ingredient directly on the follicle for an itchy scalp treatment that works.
Reclaim the freedom to wear black. Stop checking your shoulders. Buy Dermabon now and treat your scalp the right way.
Coal Tar: The Ally Against Scalp Itch
Why do we use Coal Tar for the head?
As a specialist, I prefer Coal Tar over many other actives for Scalp Psoriasis because of its dual action: it is keratoplastic and antipruritic.
- Breaking the Scale: The scalp often accumulates much thicker scales than the body because hair traps the dead skin cells. Coal Tar helps to break down this excess keratin, allowing the scales to wash away naturally during rinsing. This solves the “snowflake” effect.
- Stopping the Itch: The itch of scalp psoriasis can be maddening, often leading to scratching that causes bleeding and hair loss (traction alopecia). Coal Tar soothes the nerve endings, reducing the urge to scratch.
Unlike Salicylic Acid, which can sometimes make hair brittle and dry, Coal Tar in our nourishing soap base helps maintain a healthier environment for the hair follicle.
A Steroid-Free Solution for Your Hair
One of the biggest concerns in Trichology is the long-term health of the hair follicle.
Chronic use of high-potency topical steroids on the scalp can lead to thinning of the skin (atrophy). On the scalp, a healthy dermis is required to anchor the hair root. If the skin becomes too thin or compromised, it can negatively impact hair growth and density.
Dermabon offers a steroid-free alternative.
By managing the inflammation and scaling with Coal Tar, you avoid the risks associated with long-term steroid use. You are protecting the “soil” (your scalp) so the “plant” (your hair) can thrive.
Furthermore, many psoriasis shampoos smell chemically distinct or medicinal. While Dermabon has the characteristic scent of Coal Tar during use, it rinses out cleanly. You can follow up with your favorite fragrant conditioner on the ends of your hair (avoiding the scalp) to keep your hair smelling fresh and looking shiny.
Frequently Asked Questions
Patients often have very specific concerns when it comes to their hair. Here are the answers.
Can I use my regular conditioner?
Yes. Dermabon treats the scalp; conditioner treats the hair fiber. After rinsing out the Dermabon (following the 3-5 minute wait), apply your favorite conditioner from the mid-lengths to the ends of your hair. This ensures your hair remains soft and manageable.
Will Coal Tar stain my blonde or gray hair?
Coal Tar is dark, but in our formulation, it is designed to rinse out. However, hair that is extremely porous, bleached platinum, or white/gray can sometimes grab pigment. We recommend doing a patch test on a hidden strand of hair first. For most users, thorough rinsing prevents any discoloration.
Is it safe for color-treated hair?
Dermabon is generally safe for colored hair. It does not contain the harsh stripping sulfates found in many dandruff shampoos. However, because it is a treatment product, we recommend spacing out its use immediately after a fresh color service to preserve the vibrancy of your dye.
Does it cause hair loss?
Psoriasis itself causes hair loss due to inflammation and scratching. By treating the psoriasis with Dermabon, you are actually creating a better environment for hair growth. It does not cause hair loss; it helps prevent the loss associated with the disease.
How often should I wash my hair with it?
During an active flare-up, we recommend daily use or at least every other day until the plaques clear. Once the scalp is healthy, you can switch to maintenance mode, using it 1-2 times a week.
Conclusion
You do not have to choose between treating your psoriasis and having nice hair. For too long, patients have suffered with medicinal shampoos that leave their hair feeling like straw, or have avoided treatment to save their hairstyle, only to suffer from the itch.
Scalp Psoriasis is manageable. With the right technique—treating the scalp with Dermabon, waiting the required time, and rinsing thoroughly—you can eliminate the visible flakes.
Imagine wearing a dark shirt without a second thought. Imagine someone standing behind you in line without you feeling self-conscious about the back of your neck. That confidence is what we want to restore.
