Rheumatoid arthritis and hair loss can occur together for a number of reasons. However, hair loss is rarely caused directly by rheumatoid arthritis, but rather by factors that coincide with it, such as taking certain medications, stress, and concurrent conditions.
âThere are so many possible causes of hair loss [unrelated to rheumatoid arthritis], so we have to rule out other causes too,â says Ashira Blazer, MD, a rheumatologist and Assistant Professor in the Department of Medicine at NYU Grossman School of Medicine. âWe all naturally lose hair over time. As we age, that not only can accelerate, but the follicles start to thin so the hairs that come back might be a little thinner.â
But if youâre experiencing out-of-the-ordinary hair loss (large patches or patterns of loss, for example) it could be due to factors related to your RA.
Although hair loss isnât harmful, it can be devastating. It can change the way you see yourself and hurt your self-confidence.
âThereâs no question that hair loss is exceedingly burdensome,â says Adam Friedman, MD, Professor and Chair of Dermatology at George Washington University School of Medicine. âYour hair is your crown and itâs something that tells the world about you.â
But hereâs the good news: Hair often grows back and there are many ways to treat hair loss. By talking to your doctor about rheumatoid arthritis and hair loss, you can work together to pinpoint the causes, treatment options, and ways to cope.
Hair Loss: Whatâs Normal, Whatâs Not?
You can tell if youâre experiencing out-of-the-ordinary hair loss if youâre spotting strands of hair in places you normally wouldnât.
âWhen Iâm asking about hair loss that might be pathologic, I say, âWhen you wake up in the morning, do you notice hair on your pillow?ââ says Dr. Blazer. âWe all lose hair in the shower, or when we brush and comb. Itâs really when youâre noticing hair loss where you shouldnât, or patterns of hair loss, like patches.â
Consider whether amount of hair youâre shedding is more than usual (taking pictures can help you track your hair growth).
âIf what you are experiencing is strikingly different from your normal, it is worth asking your doctor about it,â says Carolyn Goh, MD, a dermatologist at UCLA Health Encino. âTrue patches of hair loss or rashes on the scalp along with the hair loss are often signs of more serious hair loss.â
Common Causes of Hair Loss in Rheumatoid Arthritis
âIf itâs something that comes up kind of quickly, that would suggest itâs a medication, especially if itâs a medication thatâs recently been changed,â says Max Hamburger, MD, Founder and Executive Chairman of United Rheumatology, a national rheumatology care management organization. âOr it might suggest another illness. Other things can happen to a patient at the same time they have rheumatoid arthritis.â
Here are common reasons people with rheumatoid arthritis may encounter hair loss.
Medications
Certain arthritis medications are one of the most common causes of hair loss in people with rheumatoid arthritis, yet it is still not very common to experience hair loss from your medications.Â
Methotrexate
âThe most common drug we start with in rheumatoid arthritis is methotrexate, and weâre very familiar with the possibility that this drug can cause thinning of hair,â says Dr. Hamburger. âMany of us will concurrently start [a patient on] folic acid supplements along with methotrexate because that seems to mitigate the hair thinning.â
Methotrexate is a DMARD, or a disease-modifying antirheumatic drug. Some DMARDs affect hair cells.
Study results on how common hair loss related to methotrexate is in rheumatoid arthritis vary widely. In one recent British study of a group of 1,069 RA patients who had started methotrexate and was observed at six months and a year, hair loss was reported in 8 percent of people. A small Polish study (68 people) from 2019 found that hair loss after starting methotrexate occurred in nearly 30 percent of participants. And another study from researchers in India analyzed hair loss in nearly 100 RA patients who just started taking low-dose methotrexate. Researchers compared their rate of hair loss to a control group of patients and found that low-dose methotrexate didnât seem to cause increased hair loss in RA patients.
Likewise, some CreakyJoints community members report lost hair from methotrexate while others have not. â[I] lost so much hair I canât look at myself in the mirror,â Elise V. shared on Facebook.
âI had long, thick, stick straight hair my whole life until I started taking methotrexate,â says CreakyJoints community member Lyn C. âI lost so much hair. When I finally failed methotrexate and my hair grew back, it was curly! Nothing that I’ve been on since has made my hair fall out like methotrexate and it’s stayed curly ever since.â
On the other hand, Maria E., who has been on methotrexate since February, says, âmy hair has been fine so far.â
Many people associate methotrexate as a type of chemotherapy for cancer (which is well-known to cause hair loss), but keep in mind that receiving methotrexate for arthritis treatment is very different from chemotherapy based on the dose and method of delivery â and is not likely to cause the same type of hair loss. (The dose of methotrexate when used for treating cancer is much bigger than that used for inflammatory arthritis like RA.)
Most people start by taking methotrexate via oral pills, but if youâre experiencing hair loss, you may see better results by switching from oral to injectable forms of the drug.
Only a small percent of people will have hair loss related to their DMARDs, says Dr. Blazer. âSo I really have to tease out what else is going on, because I donât want to unnecessarily stop medication that may be helping with rheumatoid arthritis [if thatâs not actually the] cause of hair loss.â
Leflunomide
Another DMARD thatâs used far less commonly nowadays but is also associated with hair loss is leflunomide (Arava).
âIt certainly causes hair loss and can cause significant hair loss,â says Dr. Hamburger. âIâve had some patients bring bags of hair that had fallen out into the office, so itâs been a limiting factor â but leflunomide isnât used much these days.â
Leflunomide has largely been replaced by biologics for rheumatoid arthritis.
JAK Inhibitors
On the other hand, certain medications may actually help with hair loss: Tofacitinib (Xeljanz) is a JAK inhibitor that has been studied as a treatment for alopecia areata, an autoimmune form of hair loss.
In this case, the drug seems to have the benefit of decreasing inflammation in hair follicles in that autoimmune condition. Alopecia areata and rheumatoid arthritis donât commonly coexist, but itâs still important to note that this rheumatoid arthritis treatment wonât exacerbate hair loss.
JAK inhibitors may be an option for you if youâve experienced hair thinning from other medications like methotrexate.
âThe good news is we have newer medications that are more targeted, donât necessarily have hair loss as a side effect, like the JAK inhibitors, a class of immune-modulating medications,â says Dr. Friedman.
Other Autoimmune Diseases
Several autoimmune diseases have been linked to hair loss. These can sometimes also affect people with rheumatoid arthritis, which is why itâs important for you and your doctor to work together to figure out what could be causing hair loss.
Alopecia
Alopecia areata is an autoimmune condition that affects about 1.7 percent of the population. It can co-occur with rheumatoid arthritis, although this isnât common. It develops when the body attacks its own hair follicles, which can lead to hair loss anywhere on the body, per the American Academy of Dermatology (AAD). Periods of hair loss and hair growth are unpredictable with this condition.
Thyroid Disease
Thyroid disease occurs when your thyroid makes too much or too little of important hormones that play key roles throughout your bodyâs systems, per the Cleveland Clinic. Hashimotoâs thyroiditis is an inherited type of hypothyroidism (where your body makes too little of the important hormones) in which the bodyâs cells attack the thyroid.
Severe and prolonged thyroid disease can cause hair loss that affects the entire scalp and appears uniformly sparse, per the British Thyroid Foundation.
âThe most common disease that I see associated with hair loss in patients with RA is actually the comorbidity of thyroid disease,â says Dr. Hamburger. âSo a lot of my [RA patients] have thyroid disease, and theyâve had Hashimotoâs thyroiditis, and often that precedes the diagnosis of RA by a long time.â
Research has shown that people with rheumatoid arthritis are more likely to develop a thyroid condition than the general population, and vice versa. In fact, 14 percent of people with Hashimotoâs thyroiditis had another autoimmune disease, most commonly rheumatoid arthritis, according to a study in the American Journal of Medicine.
Lupus
Lupus is another autoimmune disease that can sometimes co-occur with rheumatoid arthritis and can cause hair shedding. Thatâs because lupus can cause widespread inflammation that typically involves your skin, especially on your face and scalp, per the Mayo Clinic. This can cause your hair to gradually thin out or for clumps of hair to fall out.
âA lot of autoimmune diseases overlap with each other,â says Dr. Blazer. âSome people may have lupus and also rheumatoid arthritis. Lupus is a big culprit of hair loss.â
Stress
There are three ways stress can be linked to hair loss, according to the Mayo Clinic. Living with a chronic illness like RA can increase stress levels and cause chronic stress.
- Alopecia areata: Severe stress may also play a role in alopecia areata, in which the bodyâs immune system attacks the hair follicles.
- Telogen effluvium: When youâre highly stressed, it can push your hair follicles into a resting phase. After a few months, all the affected hairs can fall out suddenly when you wash or comb your hair.
- Trichotillomania: This is the irresistible urge to pull out your own hair from your scalp. This can be a way of dealing with unpleasant feelings like stress, tension, or even boredom and loneliness.
Related to telogen effluvium, your stress levels can affect what stage your hair stays in.
âOur hair has two phases â thereâs the anagen phase, where the hair is actively growing, and the telogen phase, in which the hair is actually in a resting phase,â says Dr. Blazer. âWhen you lose hair in the telogen phase, youâre not going to replace it as quickly. Patients who have stress, especially related to chronic illness, may stay in that telogen phase longer. That means when their hairs fall out, theyâre not replacing them.â
Stressful events can include rheumatoid arthritis flares, treatment changes, and managing condition side effects or comorbidities, as well as big life event-type stressors that can affect everyone, such as beginning a new job or moving.
These events can also cause you to lose hairs you would normally lose but in a shorter time frame â at rates of 400 to 600 hairs per day versus 100 to 200 during non-stressful times, says Dr. Friedman. This can persist for a few months and then plateau. As long as no other factors are affecting hair growth, the hair will come back, but the process can take a year.
Treatment for Hair Loss
Although hair loss technically doesnât need to be treated, it can have a significant impact on your self-esteem and confidence â which is reason enough to address it. Plus, hair loss could be indicative of other issues like mineral deficiencies or unknown illnesses.
âJust on its own merits, we donât need to treat hair thinning, but I donât want to underestimate the significance of aesthetics,â says Dr. Hamburger. âOur patients suffer enough from damage to their joints, swollen joints, and sometimes weight loss or muscle wasting. Theyâve got enough going on with their appearance and their self-image, they certainly donât need something as important as hair loss to deal with, too.â
Talk to your doctor to find out whether one of the following will help treat your RA-related hair loss.
Medication reevaluation
If a medication like methotrexate is causing your hair to fall out, itâs worth reevaluating if thatâs the right therapy for you.
âIf there is an offending medication, try to switch the medication,â says Dr. Blazer. âWe have so many medications for rheumatoid arthritis, that we really have many options and often we can find something that you can do to increase the hair growth.â
However, stopping medication is not something that should be done without the guidance of your doctor, who will consider your entire medical history.
âIf I had a patient on methotrexate who was having prominent hair loss, Iâd be looking carefully at their blood counts,â says Dr. Hamburger. âHair loss would be a sign for me to pay attention to the things I should ideally be paying attention to.â
Hair loss medications
These will typically be used if youâre experiencing male- or female-pattern baldness â patterns of hair loss like thinning on the crown for men or thinning at the part for women. This type of hair thinning is commonly due to genetics and the natural process of aging rather than medications, stress, or underlying conditions.
However, there are some treatments available to treat the hormonal changes that play a role in this type of hair loss.
âFrom the hormonal perspective, we use several medications, most of them off-label,â says Dr. Friedman. âThe only one thatâs actually approved is finasteride [Propecia] for male-pattern hair loss. But for women, we use two different medicines that go after hormones â spironolactone and finasteride.â
Spironolactone is a type of diuretic used to treat high blood pressure, but it can block DHT, which is the form of testosterone that can cause the hair follicles to shrink if youâre sensitive to it. It is used for women of childbearing years.
Finasteride is more potent and prevents the production of DHT from testosterone, but itâs not used in women of child-bearing years, says Dr. Friedman.
Minoxidil, or Rogaine, can also be applied to the scalp to stimulate hair growth in adult men and women with certain types of baldness, per the Mayo Clinic.
âGenerally speaking, topical minoxidil â which is available over the counter â can be used for hair loss from any cause, including medications or chronic illnesses like rheumatoid arthritis,â says Dr. Goh. âLow-level laser light therapy is another over-the-counter option that is generally safe for hair loss from any cause. Most other treatments for specific types of hair loss would need to be prescribed by a dermatologist.â
Folic acid supplements
âMethotrexate works by interfering with folic acid, and folic acid is very important for the reproduction of some cells, particularly cells that reproduce fairly rapidly,â says Dr. Hamburger. âWe know that we can block the adverse effects of methotrexate by supplying folic acid, and if itâs done with the right kind of scheduling, it wonât interfere with the therapeutic effects â but it can mitigate the side effects.â
That said, outside of use with methotrexate, folic acid alone likely wonât be very effective for hair growth.
If youâre deficient in vitamin D, that could also be causing your hair thinning. Studies have shown that people with certain autoimmune diseases like multiple sclerosis or rheumatoid arthritis have vitamin D deficiency, per the AAD. But if your doctor recommends a supplement, donât expect results overnight.
âEven if you identify the vitamin D deficiency and correct it, itâs going to take a very long time to see the impact of restoring vitamin D levels because hair grows very slowly,â says Dr. Friedman. âIt grows about a centimeter a month, so youâre not going to see immediate feedback.â
And beware of supplements that promise you theyâll instantly give you thick locks of hair.
âMost of the hair supplements that are out there are pretty bogus,â says Dr. Friedman. âAnd donât watch your hair grow â itâs going to be at least a year or two until you really appreciate a difference.â
 Stress management
Controlling your stress levels and living an overall healthy lifestyle is important for your hair. âAnything you can do to mitigate stress may help,â says Dr. Friedman. âThings like meditation, yoga, and exercise will help decrease the feeling of angst.â
Eating a vitamin-rich and protein-rich diet, getting enough sleep, and even hydration are also important for your hair health.
âHydration is really important for your bodyâs self-regulation in general,â says Dr. Blazer. âI want to make sure youâre in as healthful of a state as possible. Hair follicles thrive when you have healthy blood flow to the scalp. Being well hydrated will help feed nutrients to the follicle and help it grow.â
And remember, if something isnât good for your overall health, your hair wonât love it either.
âDoing things that are generally bad for you will be bad for your hair,â says Dr. Friedman. Think: eating an unhealthy diet, not getting enough sleep, or drinking or doing drugs.
Hair protection
Keep your hair styling in moderation â think curling, straightening, or blow drying your hair â to protect it from damage. And if you do style your hair, fortify it with conditioner.
âWhen somebody says to me their hair doesnât grow beyond a certain length, itâs not that their hair stops growing, but rather that it just breaks off from damage,â says Dr. Friedman.
Here are more common habits that can further hair damage, per the AAD:
- Rubbing shampoo into the length of your hair. Instead, gently massage your scalp with shampoo and let it run through your hair when you rinse.
- Rubbing your hair with a towel. Wrap it to let it absorb the water instead.
- Brushing your wet hair. If you have straight hair, let it dry a bit before gently combing with a wide-tooth comb. If you have textured hair or tight curls, always comb hair while itâs damp with a wide-tooth comb.
- Pulling your hair back tightly. Wear it loosely instead.
As you deal with rheumatoid arthritis and hair loss, keep in mind that your doctor is there to help. There are many causes of hair loss and rheumatoid arthritis (and related factors) may or may not the primary reason for yours. Talk to your doctor about your symptoms and treatments so you can work together to figure out whatâs going on.
