Does Scalp Psoriasis Cause Hair Loss?

Reviewed by Dr. Emin Gül · Reviewed in accordance with our Editorial Standards.

Yes, scalp psoriasis can be linked to hair loss, but it is usually temporary. 

Scalp psoriasis is a chronic, hereditary, autoimmune skin condition. It happens when the immune system sends wrong signals that tell skin cells to grow too fast. Common symptoms include thick red patches, silvery scales, itching, and soreness. The condition itself does not directly cause permanent hair loss because it does not usually destroy the hair follicles. However, it can lead to temporary thinning or shedding due to the irritation it causes.

Hair loss is most often a result of hard scratching or pulling at the thick scales, which can accidentally tear hair out by the roots. Severe stress on the skin during a flare up can also push hair into a shedding phase. Fortunately, since the follicles are not dead, the hair almost always grows back once the inflammation is under control and the scalp has time to heal.

What Is Scalp Psoriasis?

Scalp psoriasis is a chronic, hereditary, autoimmune skin condition that occurs when the immune system becomes overactive and mistakenly attacks healthy skin tissue. While it is often mistaken for a simple case of dry skin, it is actually a systemic inflammatory disorder that manifests as raised, scaly patches on the scalp, often extending beyond the hairline to the forehead, neck, or behind the ears.

Under normal circumstances, skin cells develop deep within the surface and gradually rise to the top over approximately a month. However, for someone with scalp psoriasis, this timeline is drastically accelerated due to immune system overactivity. When T cells send faulty “danger” signals, the body responds by producing new skin cells in just a few days rather than weeks. Because the old cells cannot shed quickly enough to keep pace with this rapid turnover, they accumulate on the surface. This accumulation results in the formation of thick, plaque-like layers accompanied by inflammation, redness, and characteristic silver-white scaling.

What Is the Difference Between Psoriasis vs. Dandruff and Seborrheic Dermatitis?

It is very common to confuse these conditions, but they have distinct characteristics that help doctors tell them apart:

How Can Scalp Psoriasis Hair Loss Be Managed?

To manage scalp psoriasis hair loss, doctors often suggest medicated shampoos and topical steroids to lower swelling. In some cases, light therapy or stronger medications are used. It is very important to avoid scratching or picking at the scales, as this can lead to more skin damage and hair loss. Gentle care, such as using warm water and lowering stress, can help prevent future flare ups. Regular visits to a dermatologist are also important to keep the scalp healthy.

How Does Psoriasis Cause Hair Loss?

The most common cause of hair loss in scalp psoriasis is scratching or picking at the itchy scales. This physical trauma can pull hair out by the root or break the hair shaft. Large amounts of stress from a flare up can also push hair into a shedding phase. Some strong medical treatments may contribute to thinning as well. Fortunately, this type of hair loss is usually temporary. Once the psoriasis is under control and the inflammation goes down, the hair almost always grows back.

How Does Scalp Psoriasis Lead to Temporary Hair Shedding?

Scalp psoriasis hair loss is non-scarring, meaning the hair follicles remain alive and intact beneath the surface. The shedding caused by itching and scratching is usually reversible once the flare up is managed with proper treatment. As the inflammation goes away and the scalp heals, the hair cycle returns to its normal state. You can expect your hair to regrow fully once the psoriasis is under control.

Does Scalp Psoriasis Cause Permanent Hair Loss?

Scalp psoriasis rarely causes permanent hair loss. Its symptoms can make the hair weak for a short time, but the condition itself does not usually kill the hair follicles. Most people regain their hair once the psoriasis is treated and the skin irritation is reduced. Only in very rare cases can severe inflammation that is not treated for a long time cause lasting thinning. By following a treatment plan and avoiding scratching, you can help your scalp heal and your hair will grow back.

Can Psoriasis Flare-Ups Trigger Temporary Hair Shedding (Telogen Effluvium)?

A severe flare up of scalp psoriasis can sometimes trigger telogen effluvium, which is a form of temporary hair shedding. This occurs when the physical stress of the inflammation causes a large number of hair follicles to enter the resting phase at the same time. 

This condition does not damage the follicles, and your hair usually regrows after the flare subsides. You can lower the risk of this shedding by managing your stress and following your prescribed treatment. Most people find that their hair returns to its normal thickness once the psoriasis is under control and the scalp has time to recover.

Can Plaques Interfere with Normal Hair Growth?

Thick plaques can interfere with normal hair growth by blocking the scalp surface. When these scales build up, they create a physical barrier that makes it harder for hair to emerge from the skin as it should. 

Scratching or picking at the plaques increases skin damage and delays the regrowth of hair. This type of irritation can pull hair out by the roots or hurt the scalp surface. However, the hair follicles are not permanently destroyed by this process. Once the plaques are treated and the skin is cleared, your hair can grow back normally.

Can Ongoing Inflammation Affect the Scalp Environment?

Ongoing inflammation from scalp psoriasis can disrupt the scalp environment and weaken hair health. When the skin is always inflamed, the hair strands may become more fragile and less able to stay rooted. 

Prolonged inflammation might also slow down hair regrowth and trigger repeated shedding cycles over time. This occurs because the constant immune response takes focus away from normal hair growth. Fortunately, controlling the inflammation with proper treatment helps restore a healthier scalp. Once the skin is calm and clear, the hair can begin to grow back normally.

How Does Immune Overactivity Cause Scalp Psoriasis?

Scalp psoriasis is a result of the immune system becoming overactive and speeding up skin cell turnover. In a healthy body, skin cells grow and flake off over a month, but in this condition, the process takes only a few days. Immune cells mistakenly attack healthy skin, which leads to a rapid buildup of cells on the surface. These cells pile up to form the thick plaques that characterize the condition.

This faulty immune response causes inflammation, redness, itching, and silvery scaling on the scalp. Because the body is in a constant state of defense, the skin becomes thick and sore. While the condition is chronic and has no permanent cure, it can be managed with proper treatment. Using medications like topical steroids or biologics helps to calm the immune reaction and clear the skin. With the right care, most people can reduce their symptoms and keep their scalp healthy.

Can Children with Psoriasis Experience Temporary Hair Shedding?

Children with scalp psoriasis can also experience temporary hair shedding. The itching and scratching affect young scalps in the same way they affect adults. High levels of inflammation make the hair weak and more likely to fall out during a flare up.

This shedding is usually non scarring and the hair regrows once the psoriasis is controlled. Because the hair follicles stay alive, the hair will return when the scalp is healthy again. Parents should feel reassured that pediatric dermatologists can guide safe treatment for children. With regular care, it is possible to manage the condition and keep the hair growing well.

How Does Long-Term Scalp Psoriasis Affect Hair Density in Adults?

Long term scalp psoriasis may reduce hair density but it usually does not cause permanent baldness. Repeated inflammation and chronic scratching can weaken the hair follicles and lead to gradual thinning. This happens because the skin is under constant stress and the hair is often damaged by picking at the thick scales.

Most cases of this condition are non-scarring, which means that the hair can recover if the condition is well managed. The follicles are still alive beneath the surface of the skin even during a flare up. Consistent treatment and gentle scalp care help to maintain fuller hair density over time. By working with a doctor to control the immune response, you can help your scalp stay healthy and protect your hair from further thinning.

What Are the Symptoms Linked to Hair Loss?

Common symptoms of scalp psoriasis include red patches, silvery scales, itching, and burning sensations. Physical damage from picking at thick scales is the most common reason hair falls out during a flare up.

Mild symptoms involve light scaling that looks like dandruff and usually does not affect hair growth.

Moderate symptoms include well defined red patches and silvery scales that cause notable itching and can lead to some hair thinning.

Severe symptoms involve very thick and crusty plaques that cover large areas of the head and cause intense burning or soreness.

What Does Psoriasis Related Hair Loss Look Like?

Visually, hair loss related to scalp psoriasis often looks like patchy flaking where hair has been pulled out or broken. You will see areas of redness and inflammation where the skin is thick and crusty, and the hair in these spots may look sparse or brittle.

In many cases, the loss appears as diffuse thinning, which is an overall reduction in hair volume across the scalp. This happens because the inflammation and the stress of the flare up push more hairs into a shedding phase. Unlike some other types of hair loss that leave smooth bald spots, psoriasis related loss occurs right where the scales and redness are most visible. 

Where on the Scalp Is Psoriasis Hair Loss Most Noticeable?

Scalp psoriasis hair loss is most noticeable in areas with heavy plaque buildup. You will often see shedding along the hairline, on the crown of the head, and in spots where scratching is most frequent. While these patches may look thinner, the hair follicles remain intact and alive under the skin. This means the loss is not permanent because the condition does not destroy the hair roots. 

Once the plaques clear and the inflammation is under control, hair growth usually returns in those areas. Using gentle care and the right medical treatments will help your scalp heal so your hair can grow back to its normal thickness.

How to Reduce Hair Loss While Treating Psoriasis

You can reduce hair loss during scalp psoriasis treatment by using gentle care and following a proper medical plan. Avoiding scratching, harsh brushing, and picking at plaques is very important to protect the scalp and keep hair from being pulled out by the roots.

Using shampoos and medications recommended by a dermatologist helps control irritation and swelling. These treatments make it easier to remove scales without hurting the skin surface. Consistent treatment and stress management also support healthier hair regrowth by keeping the immune system calm. Most hair loss from this condition is temporary, and your hair will grow back once the inflammation is under control and the scalp has time to heal.

What Shampoo Ingredients Help with Scalp Psoriasis?

Certain medicated shampoo ingredients can ease scalp psoriasis symptoms and reduce hair shedding. Coal tar is a common choice because it helps slow down the rapid buildup of skin cells. Salicylic acid is also very helpful because it softens thick plaques, making them easier to wash away without damaging the hair.

Other active ingredients such as zinc pyrithione, ketoconazole, and selenium sulfide can reduce scaling and irritation. These ingredients help keep the scalp environment stable and less inflamed. It is important to seek dermatologist guidance to ensure safe and effective use for long term scalp health. A specialist can help you find the right balance so the treatments do not dry out your hair while they clear the skin. When the inflammation is under control, your scalp can heal and support normal hair growth.

Can Coal Tar Shampoo Help Reduce Shedding?

Coal tar shampoo can help reduce hair shedding by slowing down this rapid cell buildup. When the shampoo softens the thick plaques, it lessens the irritation and the intense urge to scratch. Protecting the scalp from scratching is one of the most effective ways to prevent hair from being pulled out or damaged at the root.

Results from using coal tar can vary between individuals, so it is best to be guided by a dermatologist. They can help you determine the right frequency of use to avoid drying out your hair. When used correctly, coal tar is often safe for long term management of the condition. By keeping the inflammation under control, you help restore a healthy environment that allows your hair to grow back normally.

Is Salicylic Acid Shampoo Effective?

Salicylic acid shampoo is effective because it helps break down and soften thick scales resulting from scalp psoriasis. By clearing these scales, it helps free hair shafts and lowers the irritation that often causes hair shedding. This process also makes it easier for other medications to reach the skin and treat the inflammation.

This type of shampoo works best when it is combined with other prescribed treatments such as topical steroids. While it is very helpful for clearing plaques, careful use is important to prevent excess dryness or irritation of the scalp. 

Are Hair Transplants an Option for Psoriasis-Related Hair Loss?

Most hair shedding from scalp psoriasis is temporary because the hair follicles remain alive and intact beneath the scales. Since the follicles are not destroyed, hair transplants are usually not an appropriate or necessary option. Your hair almost always grows back on its own once the inflammation is under control and the scalp has time to heal.

Hair transplants are only considered if scarring alopecia develops. This is a rare situation where severe and untreated inflammation causes permanent damage to the follicles, but it is not common for standard psoriasis. For most people, managing the condition with proper medical care restores natural hair growth without the need for surgery. By working with a dermatologist to reduce irritation and clear plaques, you can help your scalp recover so your hair returns to its normal thickness.

What to Know About Hair Transplants If You Have Psoriasis

Scalp psoriasis is a chronic, hereditary, autoimmune skin condition. It causes the immune system to speed up skin cell growth, which leads to symptoms like red patches, silvery scales, itching, and soreness. While hair loss is usually temporary, you should seek medical attention if you notice severe symptoms such as bleeding, pus or oozing, or extreme pain on your scalp. These signs may indicate a secondary infection or a very high level of inflammation that requires professional treatment to prevent skin damage.

Hair transplants are generally not recommended during active psoriasis because the surgery can trigger a new flare up. However, a transplant might be an option if you have permanent scarring and your psoriasis has been under control for a long time. Most people find that their hair returns naturally once they use the right medical treatments to calm their immune system.

When Should You See a Dermatologist for Psoriasis Hair Loss?

While many people begin with store-bought products when treating psoriasis, you should see a dermatologist if over the counter treatments do not improve your symptoms. Professional care is necessary when the scaling and inflammation remain thick or difficult to manage.

Medical guidance is also important if your scalp irritation becomes very painful, begins to spread, or if you have concerns about permanent scarring. Severe inflammation can sometimes lead to more significant hair shedding, but early treatment helps control the immune response and supports faster hair regrowth.

How Long Does It Take for Hair to Regrow After Psoriasis Treatment?

If you experience hair thinning during a flare up, regrowth typically begins within 8 to 12 weeks after the inflammation is under control. Because the hair follicles are usually not permanently damaged, your hair should return to its normal thickness as the scalp heals and the skin clears.

Most patients see significant hair regrowth within 3 to 6 months of starting an effective treatment. While the exact timing can vary, statistics from clinical observations in “Psoriatic alopecia: acute and chronic hair loss in 47 patients with scalp psoriasis.” researched by Runne U, Kroneisen-Wiersma P. in Dermatology show that initial new growth often appears once the thick plaques are removed and the skin is no longer red or inflamed. Full cosmetic recovery, where the hair looks as it did before the flare up, can take between 6 and 12 months.

How to Prevent Hair Loss while Managing Psoriasis

In psoriasis, most hair loss happens because of physical damage to the skin. Scratching hard or pulling at thick scales can tear hair out by the roots or break the hair shafts. Once you get the inflammation under control and the scalp heals, the hair almost always grows back.

• Avoid scratching and picking: Scratching can damage your hair roots and cause more patches to form. Keep your nails short to reduce the chance of accidentally hurting your scalp.
• Soften scales before washing: Apply warm coconut or olive oil to thick scales to soften them. This helps them lift away gently during your shower without pulling hair out.
• Use lukewarm water: Hot water strips away natural oils and makes the skin more irritated. Always wash your hair with warm water and massage the scalp with your fingertips instead of your nails.
• Hydrate your hair: Medicated shampoos can make hair dry and brittle. Use a separate fragrance-free conditioner on the ends of your hair to keep it strong and prevent breakage.
• Choose loose hairstyles: Avoid tight ponytails, braids, or buns that pull on your scalp. Keeping your hair loose reduces the tension on sensitive areas.
• Limit heat styling: Try to air dry your hair whenever possible. If you must use a blow dryer, keep it on the lowest heat setting and avoid pointing it directly at active plaques.
• Consult your dermatologist: Follow your prescribed treatment plan consistently. Using topical steroids or medicated foams as directed is the most effective way to stop the shedding cycle.

How Does Psoriasis Differ from Seborrheic Dermatitis in Causing Hair Loss?

Scalp psoriasis causes thicker plaques and more intense inflammation than other scalp issues. Because the plaques are so dry and heavy, they cause significant irritation. This often leads to temporary hair shedding as a result of both the deep inflammation and the physical trauma from scratching at the scales.

In contrast, seborrheic dermatitis involves greasy, yellowish scales and much milder inflammation. While it can cause some thinning, it usually results in less shedding than psoriasis because the scales are thinner and less likely to be forcefully removed. In both cases, the hair follicles stay alive and the hair usually grows back once the scalp is healthy again.
