7 Common Places Psoriasis Can Develop on Your Body

From health.com

AT A GLANCE

• Psoriasis can affect any part of your skin. Sometimes it can affect multiple parts of your body.
• Your elbows, knees, trunk, and scalp are among the most common areas where psoriasis develops. It can also affect your palms, soles of the feet, nails, face, and genitals.
• Certain areas of the body may be harder to treat with traditional psoriasis creams or gels, and you may need to explore other treatment options.

Psoriasis can affect almost any part of your skin. Sometimes the skin condition can affect multiple areas of the body at once or different areas over time. Could the changes on your skin be a new patch of psoriasis? Here are some places on the body where psoriasis is particularly common. (And keep in mind, the location of your psoriasis could dictate the kind of treatment that’s best for you.)

1. Elbows and Knees

Your elbows and knees are common spots for the most common kind of psoriasis, called plaque psoriasis. It leads to itchy, painful, red patches of skin that are covered by silvery-white scales. 

Usually, these patches are found in a symmetrical pattern on the outside of your knee or the outside of the elbow, called the extensor surfaces. These areas may be particularly prone to breakouts because they are exposed to more friction than other parts of your skin.

Treatment: Topical (applied directly to the skin) treatments typically work well. But based on how severe the psoriasis is, you may need different types of medication, such as oral medication, biologics, or light therapy.

2. Trunk, Arms, and Legs

People can commonly have psoriasis in areas that cover a large percentage of their skin, such as the chest, abdomen, back, arms, and legs. Most often, this is the plaque kind of psoriasis. Some people might get a kind of psoriasis called guttate psoriasis in these regions, which causes small red dots.

Treatment: Prescription creams, like vitamin D creams, corticosteroid creams, or coal tar creams, are not as effective when psoriasis affects large portions of the body. Instead, you might need treatment that you take orally or via an injection.

3. Scalp 

Around half of people with psoriasis have symptoms affecting their scalp, such as silvery-white scaly patches, itching, and pain. The scalp is one of the first places people typically experience psoriasis symptoms. However, it might not be diagnosed at first, as it’s often first mistaken for severe dandruff (seborrheic dermatitis). It is especially associated with psoriatic arthritis.

Treatment: Some people see improvements with therapeutic creams that are applied directly. However, some people find it difficult to apply the creams to their scalp, and some don’t like the way these creams look cosmetically. So, scalp psoriasis is sometimes undertreated.

4. Face

Although not as common as in other regions, up to half of people with psoriasis may have some psoriasis symptoms on their face at some point. Psoriasis can appear on any part of your face. 

Psoriasis on the face may interfere with the typical things you need to do with the muscles of your face, like chew. People with facial psoriasis also tend to have more severe psoriasis symptoms overall.

Treatment: Facial psoriasis may be more difficult to treat than psoriasis in some other parts of the body because the skin there is quite delicate. For example, it’s important not to overuse strong corticosteroid creams on your face.

5. Nails

About 40-50% of people with psoriasis have symptoms that affect their nails. It is especially associated with psoriatic arthritis.

Nail involvement in psoriasis can cause various nail changes, such as:

• Rough nails
• Brittle nails that are prone to crumbling
• Nail pitting (small dents)
• White discoloration
• Red spots on your nails
• Separation of the nail from the underlying nail bed 

Treatment: Topical medications are often not very effective at treating nail psoriasis. Injections into the nail or oral therapies may work better.

6. Palms of the Hand and Soles of the Feet

Psoriasis affects the palms of the hands or the soles of the feet in around 15% of people with the skin condition. Another word for this is palmoplantar psoriasis. It can look like plaque psoriasis, but some people get bumpy pustules.

Psoriasis that affects these parts of the body can particularly interfere with your day-to-day activities and quality of life.

Treatment: You can try some of the same topical treatments that are used for psoriasis in other places. However, certain medicated creams might not be as effective where the skin is thick, like calluses on your feet.

7. Skin Folds

Sometimes psoriasis affects areas where your skin folds together, like in your armpit, beneath your breasts, around your anus, around your belly button, or around your ears. It can also affect the external genitalia, especially in males. This type of psoriasis is called inverse psoriasis or intertriginous psoriasis.

Experts used to think that this kind of psoriasis was rare, but it’s now believed to affect about 20-30% of people with psoriasis. Usually, the areas are moist and shiny, not with the whitish scales seen in plaque psoriasis. The areas are usually clearly outlined and symmetric on both sides, with intense itchiness.

Sometimes it’s hard for healthcare providers to distinguish psoriasis in these areas from other kinds of skin conditions that can cause irritation in skin folds.

Psoriasis that affects the genitals is often especially bothersome. It can lead to embarrassment and shame, negatively impacting personal relationships. Instead of smooth and red, psoriasis here is sometimes more like the itchy white flakes of plaque psoriasis.

Treatment: Because the skin folds and sensitive areas have thinner skin, the strongest steroids are not best. Instead, non-steroidal topical medications may be safer for these areas. Your provider may also recommend that you use a powder to keep any lesions in the skin folds dry. If kept moist, you could be at risk for a fungal infection.

Can Psoriatic Arthritis Cause Hair Loss?

From everydayhealth.com

Psoriatic arthritis (PsA) is an autoimmune disease that causes inflammation of the joints, tendons, and nails. It usually occurs in people with psoriasis, an inflammatory condition causing rashes on the skin.

Symptoms can include joint pain, swelling, stiffness, and fatigue. Hair loss (alopecia) isn’t typically a sign of the disease, but it can affect some people with PsA in a roundabout way. 

“Psoriatic arthritis and hair loss are not directly linked,” explains Jennifer E. Yeh, MD, PhD, a clinical assistant professor of dermatology at Stanford University School of Medicine in California. “However, having psoriatic arthritis may predispose one to hair loss from psoriatic arthritis inflammation, from psoriatic arthritis treatment, or from an increased likelihood of having another type of autoimmune condition.” 

Physical or Psychological Stress Can Lead to Hair Loss

Psoriatic arthritis can significantly impact your emotional well-being, leading to anxiety, depression, diminished self-esteem — and particularly, stress. Chronic stress can worsen inflammation and immune dysregulation, leading to increased disease activity and more severe symptoms. Researchers note that stress may also disrupt neuroendocrine pathways, affecting cortisol levels and further dysregulating the immune system in PsA. According to the American Academy of Dermatology, stress is linked to hair loss and thinning hair.

Dr. Yeh says that both the physical and psychological stress associated with PsA can trigger a temporary type of hair loss called telogen effluvium. 

With telogen effluvium, more hairs than normal are forced into their resting phase. When this happens, they fall out at once. Most people lose about 100 strands of hair a day. But if you have telogen effluvium, you may lose up to 300 strands a day.

“While telogen effluvium is characterized by an increase in daily hair shedding, it usually reverses, and hair regrows once the underlying stressor is removed,” Yeh says.

Medications for PsA May Cause Thinning Hair

Treatments for PsA can contribute to hair loss. Some common culprits are: 

• Methotrexate It stops cells from growing — including hair follicles. About 1 to 3 percent of people who use it experience hair loss.
• Leflunomide This medicine works like methotrexate and causes hair loss in about 10 percent of people.
• Anti-TNF Therapy Research has shown that “a sizable minority” of people on TNF inhibitors develop alopecia areata, the most common inflammatory hair loss disease, at a higher prevalence than the general population, though it’s not clear why this happens.

“Treatment-related alopecia typically improves with discontinuation of the offending medicine,” says Yeh.

Comorbid Psoriasis and Hair Loss

Most, but not all, people with PsA also have psoriasis. And, if you have psoriasis, you have a 45 to 56 percent chance of developing scalp psoriasis.

Scalp psoriasis causes a dry, itchy, and inflamed scalp. “Scalp psoriasis that is not controlled irritates the hair follicles, disrupting normal hair follicle function, and thereby causing hair shedding,” says Yeh. 

If you scratch or pick at the lesions, you can also damage hair follicles. This can result in additional hair loss.

The good news is that hair loss due to scalp psoriasis is usually temporary. “Most cases show complete hair regrowth after treatment,” says Yeh.

If you have severe psoriasis plaques, you should be aware that the oral medication acitretin, occasionally used to treat persistent psoriasis, can cause hair loss.

What to Do About Hair Loss

If you have PsA and experience hair loss, talk to your doctor. If you’re not already seeing a dermatologist to manage your condition, your rheumatologist can refer you to one who may be able to determine the underlying cause of your hair loss.

Getting your symptoms under control can also help preserve your hair. “Hair loss from uncontrolled PsA reverses once the inflammation is well-controlled,” says Yeh. “It’s critical to treat concomitant scalp psoriasis so that local inflammation surrounding hair follicles on the scalp does not contribute to increased hair shedding.”

Here are some ways you can help prevent hair loss caused by scalp psoriasis.

• Try not to touch, pick, or scratch your scalp.
• Keep your fingernails short.
• Be gentle when brushing, combing, washing, or drying your hair.
• Wear a hat when you’re outside.
• Use a medicated shampoo that contains salicylic acid and follow with a moisturizing conditioner. 
• Don’t take extremely hot showers.
• Ask your doctor about a prescription treatment that can help your symptoms.
• Avoid blow-drying your hair. If you do, use a low-heat setting.
• Try to keep stress levels low.
• Follow a healthy diet.
• Avoid heavy drinking.

While hair loss associated with PsA can be frustrating, the right treatments and lifestyle habits can help you minimize shedding — and protect the hair you have.

The Takeaway

• If you have psoriatic arthritis and you’re experiencing hair loss, consult your doctor to determine the underlying cause and effective treatment strategies.
• Medications such as methotrexate and leflunomide, commonly used to manage PsA, might contribute to hair thinning, so discuss potential side effects with your healthcare provider to explore any necessary adjustments.
• Emotional and physical stress linked to PsA can cause temporary hair loss; reducing stress levels and effectively managing the disease can lead to regrowth and a healthier scalp condition.
• If you’re dealing with scalp psoriasis, measures such as medicated shampoos and avoiding scalp irritation can prevent additional hair loss and support recovery.

How to Care for Your Skin During a Severe Psoriasis Flare

From healthcentral.com

When psoriasis flares get a little out of hand, take note of these dermatologist-approved steps to soothe pain, calm inflammation, and protect your skin 

A severe psoriasis flare is more than a few thicker-than-usual plaques. Skin may become rapidly and intensely red, swollen, and cracked, with itch that feels constant and overwhelming. “I look for more widespread, thickened, scaly plaques extending beyond prior areas of involvement, along with fissuring, pain, and intensifying itch,” says Meena Singh, M.D., a board-certified dermatologist and medical director of the Skin and Hair Center in Overland Park, KS. Skin warmth or new pustules can also signal trouble. Beyond physical symptoms, severe flares often take an emotional toll, disrupting sleep, work, and daily life.

First Priority: Calm the Inflammation ASAP

During a severe flare, the main goal is to calm inflammation as quickly and safely as possible, says Dr. Singh. For flares limited to certain areas, dermatologists may temporarily use stronger topical steroids like clobetasol, often followed by steroid-sparing treatments such as roflumilast. Thick scale may be gently reduced first so medications can work better. For stubborn plaques, steroid injections may help. If symptoms spread quickly or interfere with daily life, doctors may adjust prescribed systemic or biologic treatments (if you take them) to bring inflammation under control.

Soothing Baths Can Help

Short, lukewarm baths can help calm inflamed skin and soften plaques. “I usually recommend lukewarm baths with colloidal oatmeal and occasionally Dead Sea–style salts,” says Dr. Singh. Adding a bath oil can help seal in moisture, per the Mayo Clinic. What doesn’t help: long, hot baths or showers. “Hot water and harsh soaps disrupt the skin barrier and increase inflammation, even if they feel soothing at first,” she explains. Fragrances and essential oils can also worsen flares. Bonus tip: Moisturize within two minutes of bathing to lock in hydration.

Moisturize Like a Derm

During a severe flare, the simple act of moisturizing becomes a form of treatment. “Proper moisturization alone can be therapeutic,” says Dr. Singh. She recommends thick creams or ointments—especially ceramide-containing formulas—applied at least twice daily. Prescription treatments should go on first, followed by moisturizer layered over the entire area. Timing matters, too: Apply within minutes of bathing while skin is damp. “Heavier creams work better than lotions,” adds Harvard-trained dermatologist Calvin Williams, M.D., who is the director at the Essential Dermatology Group in Bedford, TX, noting that dry skin worsens psoriasis and prolongs inflammation.

Using Bandaging and Occlusion Safely

Occlusion—a.k.a. covering treated skin—can reduce scaling and protect cracked areas when done carefully. Cotton gloves, socks, or soft dressings over petroleum-based ointments can help during severe flares. “Occlusion can be effective [for severe psoriasis], but it should be done under dermatologic guidance,” says Dr. Singh, since it increases absorption of topical steroids. Overuse may raise the risk of side effects like thinning skin. Contact your physician for guidance on bandaging and occlusion; they may even be able to walk you through it virtually if needed.

Scalp Psoriasis Crisis Care

Scalp flares can be especially painful and frustrating, particularly when plaques spread to the hairline or behind the ears. Medicated shampoos help reduce inflammation and scaling, but they should be used gently to avoid irritation. Overnight treatments can soften thick plaques, making them easier to remove in the morning. The biggest thing: “Avoid aggressive picking,” Dr. Singh warns, since it can worsen inflammation and raise the risk of infection. Consistent, careful care can ease pain while protecting both the scalp and hair during severe flares.

Managing Pain, Itch, and Cracking

During severe flares, pain and intense itch often go hand in hand. Cooling gels, cold compresses, or ice packs wrapped in cloth can calm burning skin, notes the American Academy of Dermatology. Antihistamines may help control night-time itch and improve sleep, even though they don’t treat inflammation. The catch-22 is that “dry skin worsens psoriasis,” says Dr. Williams, making frequent moisturizing and humidifier use especially important. When skin cracks, apply thick ointments and protective dressings to reduce pain with movement. To limit damage, keep nails trimmed, wear cotton gloves at night, and avoid scratching whenever possible.

Clothing and Daily-Life Hacks

Your daily habits can either soothe or aggravate inflamed skin. Soft, breathable fabrics like cotton reduce friction, while tight seams and rough materials can worsen plaques. Loose-fitting clothes can also help prevent overheating, which can intensify itch. Fragrance-free detergents and skipping fabric softeners are also key to avoid unnecessary skin irritation. Protective dressings under clothing can shield painful plaques during the day. These small adjustments won’t stop a flare—but they can make work, errands, and social situations far more manageable.

When It’s Time for Medical Help

“Rapidly spreading disease, pain that outweighs itch, pustules, or widespread redness are red flags,” says Dr. Singh. Fever, chills, or bleeding that won’t stop could signal an infection and need immediate attention. Other infection signs include increased warmth, oozing, yellow crusting, or worsening pain despite treatment. Dr. Williams adds that flares not responding to usual treatments should also prompt a medical visit. In rare cases, severe flares can lead to erythroderma, a medical emergency marked by near-total redness of the skin. Bottom line: When symptoms escalate, don’t wait.

Work With Your Dermatologist

Planning ahead can reduce stress when severe psoriasis flares hit. Dermatologists often recommend a personalized flare-response plan outlining which treatments to use, where to apply them, and when to call for help. “Psoriasis is not just a skin disease—it’s a systemic inflammatory condition,” says Dr. Singh. Having a ready-to-go flare kit with prescriptions, moisturizers, and dressings can help you feel more in control when flares strike. Meanwhile, tracking triggers like stress, illness, or medication changes can help reduce future flares and improve long-term control.

What’s the Best Way to Wash Your Hair if You Have Scalp Psoriasis?

From everydayhealth.com

If you have psoriasis on your scalp, it can cause redness, thick scales or patches, itching, and even pain. It can also cause temporary hair loss. It’s similar to psoriasis on other parts of the body, but hair can trap the scales, causing them to build up more. 

There are a few prescription medications that are commonly used to treat scalp psoriasis. But you can get better results from your medications if you wash your hair with psoriasis-specific shampoo. 

For moderate to serious psoriasis, psoriasis shampoos are not that effective alone, but they can help your medications work better when used in combination with them. 

“These shampoos should be thought of as a complementary therapy,” says Lawrence J. Green, MD, a clinical professor of dermatology at George Washington University School of Medicine in Washington, DC. “They’re not on your hair and scalp for long enough to be a primary treatment.” 

For some people with very mild scalp psoriasis, the shampoos may be enough to keep it under control, says Alix Charles, MD, a dermatologist in Hinsdale, Illinois.

Here’s a breakdown of the different types of shampoos, how to use them, and what else you should be doing to keep your scalp psoriasis under control.

Types of Psoriasis Shampoos

There are two main types of over-the-counter medicated shampoos for psoriasis — those with coal tar, and those with salicylic acid. Both of these ingredients are approved by the U.S. Food and Drug Administration for psoriasis.

Coal tar shampoos can slow skin cell growth, reduce scaling, and help with redness, inflammation, and itchiness. The downside is that they’re a bit messy and can stain clothing, and they tend to have a particular smell.

Shampoos with salicylic acid are used to exfoliate skin and soften and remove the patches. “It makes it easier for any topical medication to penetrate into the scalp,” says Dr. Green. That can make medications more effective. These shampoos typically contain 3 percent salicylic acid. Some salicylic shampoos are recommended by the National Psoriasis Foundation.

Psoriasis shampoos may contain other ingredients that can soothe irritation, reduce itching, and restore moisture to your scalp.

There’s also a prescription shampoo, which contains clobetasol propionate, a type of steroid. But dermatologists try to avoid using steroids when possible, because they can’t be used for more than a few weeks. 

“I don’t use prescription shampoos because they’re not on the scalp long enough to help much, and we have better medications,” says Green.

How to Use Psoriasis Shampoo

We think of shampoo as being for the hair, but it’s important to apply psoriasis shampoo to your scalp as much as possible. Here’s how to do it:

• Apply shampoo to your scalp. Try to separate sections of the hair and apply the shampoo to the scalp.
• Gently massage. After applying the shampoo, gently massage it into your scalp. Don’t vigorously rub your scalp, as that can irritate your skin and make the psoriasis worse. 
• Wait   Leave the shampoo in for five minutes. 
• Alternate between psoriasis-specific and regular shampoo. It’s a good idea to alternate a medicated shampoo with a regular shampoo, so that you don’t dry out your hair and scalp, says Green. If you have thick scales that need to be removed, you can use the salicylic acid shampoo daily until it improves. Use the medicated shampoo at least three times a week.
• Stop when your scalp clears. When the psoriasis clears, you don’t need to use the medicated shampoo anymore. “These are only meant to be used when using medication, not as long-term maintenance therapies,” says Green.
What About Scale Softeners?

If you have very thick scales, you may need a scale softener that stays on your scalp longer. There are gels that you apply to your scalp and leave on. One study found that applying salicylic acid followed by a moisturizer reduced redness and scaling in people with psoriasis. This is used more like a medication than a shampoo, but it may not be necessary. 

“If you’re using one of the prescription medications, you don’t usually need [a scale softener], because you can get enough of the scale off with a medicated shampoo,” says Green.

Conditioning Your Hair
It’s important to use a conditioner whenever you shampoo. Psoriasis shampoos can be very drying to your hair. Using a conditioner on the hair shaft can add moisture back in. 
Some psoriasis shampoos contain ingredients that moisturize your hair, but the additional step of using a conditioner can add extra moisture. You may want to also apply a few drops of hair oil or serum to your scalp to keep it moisturized.
Common Mistakes
When you use a psoriasis shampoo, you need to have a slightly different approach than with regular shampoo. Some common mistakes people make when using psoriasis shampoo may prevent them from getting the full benefit of the shampoo — and in some cases, they can even make the psoriasis worse. Here are few mistakes dermatologists see:
1. Washing your hair not your scalp: Try not to think of shampoos as just being for your hair. It’s important for the active ingredients to have contact with your scalp. Be sure to gently massage it into your scalp.
1. Rinsing the shampoo out too quickly: Make sure the shampoo is in contact with the your scalp for at least five minutes before you rinse it out, says Dr. Charles. Contact time is important for the ingredients to work.
2. Skipping shampoos: It’s helpful to shampoo every day, as it can help clear out the debris and oils that can make psoriasis worse. Just be sure to alternate a medicated shampoo with a regular shampoo. 
3. Scratching or rubbing your scalp: Scalp psoriasis can be very itchy, and shampooing and massaging it may trigger the itchiness. Still, it’s important to avoid scratching or trying to rub away the itch. That can make psoriasis worse and may make your scalp bleed or cause hair loss. 
4. Blow-drying your hair: Scalp psoriasis can make your scalp very dry. Using a blow-dryer with hot air can dry it out even more. Instead, let your hair air-dry or use a dryer on the cool setting.
5. Picking at the scales: Shampoo and medication may help loosen scales, which is the goal. But picking at them can cause psoriasis to flare, may cause bleeding, and can even cause scarring and hair loss.

6. The Takeaway

   • Using a medicated shampoo that contains coal tar or salicylic acid can help to alleviate scaling and itching caused by psoriasis.
   • Apply the shampoo directly to your scalp, gently massage, and leave it in for at least five minutes to give the active ingredients enough time to work.
   • Moisturizing with a conditioner after shampooing can help keep your scalp hydrated and reduce dryness-associated itchiness.
   • Avoid scratching or rubbing your scalp, as it can worsen psoriasis and lead to complications like bleeding and hair loss. Instead, talk to your healthcare provider about additional treatments if symptoms persist or worsen.
