Psoriasis is a skin condition that makes your body create too many skin cells, leading to red, scaly patches. When these patches show up on your scalp, it is natural to worry about your hair. The direct answer is yes, psoriasis can cause hair loss, but it is almost always temporary. The hair loss happens because of the inflammation and the physical stress on your hair follicles, not because the follicles are permanently damaged. Once the psoriasis flare is treated and the inflammation goes down, your hair typically grows back on its own.
How Does Psoriasis Lead to Hair Loss?
The connection between psoriasis and hair loss is not about the hair root being destroyed. It is about what happens on the surface and just below it. When you have scalp psoriasis, thick plaques of dead skin cells build up. These plaques create a tough crust that can trap hair shafts.
When you scratch or pick at these plaques, you can pull out strands of hair. The constant scratching also irritates the scalp further, which can weaken the hair at the root. This is called traction alopecia when the pulling is mechanical. The inflammation itself can also push hair follicles into a resting phase called telogen effluvium. This means more hairs than normal stop growing and eventually fall out.
Research shows that the hair loss from psoriasis is rarely permanent. The follicles are not scarred or destroyed in most cases. Once the inflammation is controlled, the hair cycle returns to normal. Current research suggests that treating the scalp psoriasis is the most effective way to stop the hair loss and allow regrowth.
Is the Hair Loss from Psoriasis Permanent or Temporary?
The vast majority of hair loss from psoriasis is temporary. This is one of the most important things to understand. If you treat the psoriasis effectively, your hair will likely grow back within a few months.
There is a rare exception. A severe form of psoriasis called pustular psoriasis or erythrodermic psoriasis can cause scarring of the scalp. Scarring can permanently damage hair follicles. But this is not common. For most people with plaque psoriasis on the scalp, the hair loss is reversible.
One study found that about 50% of people with scalp psoriasis report some degree of hair loss during flares. But the same study showed that hair regrowth was the norm once treatment started. The key is to avoid aggressive scratching and picking. That mechanical damage is what increases the risk of longer-term thinning.
What Are the Best Treatments for Scalp Psoriasis and Hair Loss?
Treating the psoriasis is the first step to stopping hair loss. You cannot regrow hair if the inflammation is still active. There are several options that work well for the scalp.
Topical treatments are usually the first line of defense. These include corticosteroid lotions, foams, and solutions. They are easier to apply to the scalp than thick creams. Vitamin D analogs like calcipotriene also help slow skin cell growth. Coal tar shampoos and salicylic acid products can soften plaques so they come off gently without pulling hair.
Medicated shampoos are a practical choice. Look for ones with coal tar, salicylic acid, or selenium sulfide. They do not cure psoriasis, but they reduce scaling and itching. Less itching means less scratching and less hair loss.
Biologic drugs are for moderate to severe cases. These are injectable medications that target specific parts of the immune system. They can clear scalp psoriasis completely in many people. When the scalp clears, hair loss stops and regrowth begins. Biologics are not for everyone, but they are very effective for stubborn cases.
Here is a quick comparison of common treatment options:
| Treatment Type | How It Works | Effect on Hair Loss |
|---|---|---|
| Topical corticosteroids | Reduce inflammation and slow skin cell growth | Stops hair loss by calming the flare |
| Coal tar shampoos | Slow rapid skin cell turnover | Reduces scaling and itching, which limits mechanical hair loss |
| Salicylic acid products | Help remove thick scales | Prevents plaque buildup that traps hair |
| Biologic medications | Block specific immune signals that cause psoriasis | Clears scalp completely, allowing full regrowth |
What Should You Avoid When You Have Scalp Psoriasis?
Some things make scalp psoriasis worse and increase hair loss. Avoiding them can make a big difference in how fast your hair grows back.
Avoid scratching or picking at plaques. This is the number one cause of hair loss during a psoriasis flare. When you pick off a scale, you often pull out the hair attached to it. The scratching also damages the skin barrier, which can make inflammation worse. Instead, use a medicated shampoo or a salicylic acid solution to gently soften scales before washing.
Do not use harsh hair products. Strong dyes, bleaches, and chemical straighteners can irritate an already inflamed scalp. This can trigger more flaking and more hair loss. Stick to gentle, fragrance-free shampoos and conditioners while your scalp is flaring.
Avoid heat styling. Blow dryers, curling irons, and flat irons can dry out the scalp and worsen psoriasis. If you must use heat, keep it on the lowest setting and avoid direct contact with the scalp.
Do not stop treatment too early. Scalp psoriasis can look like it is gone but still be active underneath. Stopping treatment early can cause a rebound flare, which can restart the hair loss cycle. Follow your dermatologist’s instructions even after the plaques clear.
Some people report that stress makes their psoriasis worse, and that is backed by evidence. High stress levels can trigger flares and increase inflammation. Managing stress through exercise, sleep, or relaxation techniques may help reduce the frequency of flares.
What Are Common Misconceptions About Psoriasis and Hair Loss?
There is a lot of misinformation online about psoriasis and hair loss. Some of it can lead people to waste money on treatments that do not work or to worry unnecessarily.
Misconception: Psoriasis causes permanent baldness. This is false for the vast majority of people. As mentioned earlier, the hair loss is almost always temporary. The follicles are not destroyed. If you have persistent thinning, it is more likely due to another condition like male or female pattern baldness that happens to coexist with psoriasis.
Misconception: You can regrow hair while the psoriasis is active. This is not realistic. The inflammation that causes the plaques also disrupts the hair growth cycle. You must treat the psoriasis first. Once the scalp is clear, the hair follicles can start producing new hairs. Trying to regrow hair while ignoring the psoriasis is like watering a plant in soil that is full of weeds.
Misconception: Expensive shampoos or natural remedies can cure scalp psoriasis. Many products claim to cure psoriasis, but there is no cure. Some natural ingredients like tea tree oil or aloe vera may soothe the scalp for some people, but strong evidence is limited. They are not substitutes for proven medical treatments. As of 2026, no natural remedy has been shown in clinical trials to clear scalp psoriasis reliably.
Misconception: Hair loss from psoriasis always happens evenly. It can be patchy. You might notice hair thinning in the exact spots where the thickest plaques are. This is because the inflammation is concentrated there. Once the plaque clears, the hair in that spot usually grows back.
When Should You See a Dermatologist for Scalp Psoriasis?
If you have scalp psoriasis and notice hair loss, it is a good idea to see a dermatologist. You do not need to wait until the hair loss is severe. Early treatment can prevent more hair from falling out and speed up regrowth.
You should see a doctor if over-the-counter medicated shampoos do not help after a few weeks. If the plaques are very thick or cover most of your scalp, prescription treatments are usually needed. If you see signs of a skin infection like oozing, yellow crusting, or spreading redness, get medical attention promptly.
Also see a dermatologist if your hair loss continues even after the psoriasis seems to be improving. This could mean you have another type of hair loss happening at the same time. A dermatologist can examine your scalp with a tool called a dermoscope to check the health of your hair follicles and look for scarring.
Treatment plans for scalp psoriasis often need to be adjusted over time. What works for one person may not work for another. A dermatologist can help you find the right combination of treatments for your specific case.
If you have joint pain along with scalp psoriasis, mention it to your doctor. This could be psoriatic arthritis, which affects about 30% of people with psoriasis. Treating the systemic inflammation can also help your scalp and your hair.
