Sjögren's syndrome and hair loss are more closely linked than many patients and clinicians realise. Sjögren's syndrome is a chronic autoimmune condition primarily known for causing dry eyes and dry mouth, but its systemic effects can extend to the skin and hair follicles. Hair loss in Sjögren's may result from several overlapping mechanisms, including chronic inflammation, nutritional deficiencies, coexisting autoimmune thyroid disease, and medication side effects. Understanding these connections is essential for accurate diagnosis and effective management within the NHS.
Summary: Sjögren's syndrome can cause hair loss through chronic systemic inflammation, nutritional deficiencies, coexisting autoimmune thyroid disease, and as a potential side effect of medications such as hydroxychloroquine.
- Sjögren's syndrome is a systemic autoimmune condition; hair loss is a recognised but often overlooked feature, not among its most publicised symptoms.
- The most common pattern is telogen effluvium — diffuse shedding triggered by systemic inflammation, nutritional deficiency, or intercurrent illness.
- Alopecia areata, an autoimmune condition in its own right, occurs at higher rates in people with Sjögren's due to shared autoimmune susceptibility.
- Hydroxychloroquine, commonly prescribed for Sjögren's, lists alopecia as an adverse reaction of unknown frequency in its UK Summary of Product Characteristics (SmPC).
- Autoimmune thyroid disease (e.g. Hashimoto's thyroiditis) frequently coexists with Sjögren's and is itself a well-established cause of diffuse hair thinning.
- Early dermatology referral is essential if scarring alopecia is suspected, as irreversible follicle loss can occur without prompt treatment.

How Sjögren's Syndrome Can Cause Hair Loss
Sjögren's syndrome can cause hair loss through chronic autoimmune inflammation disrupting the hair growth cycle, nutritional deficiencies, coexisting hypothyroidism, and as a potential adverse effect of hydroxychloroquine.

Sjögren's syndrome is a chronic autoimmune condition in which the immune system mistakenly attacks the body's moisture-producing glands, most notably the salivary and lacrimal glands. This results in the hallmark symptoms of dry eyes and dry mouth. However, Sjögren's is a systemic disease, meaning it can affect multiple organ systems — including the skin and hair follicles.
Hair loss in Sjögren's syndrome is reported by some patients, though it is not among the most widely publicised features of the condition. The mechanisms are thought to be multifactorial. Chronic systemic inflammation driven by autoimmune activity can disrupt the normal hair growth cycle, pushing follicles prematurely into the resting (telogen) phase. Inflammatory cytokines associated with autoimmune conditions — such as interleukins and tumour necrosis factor — may also directly impair follicular function.
Nutritional deficiencies may contribute. In Sjögren's syndrome, reduced dietary intake due to xerostomia (dry mouth), associated autoimmune gastrointestinal conditions (such as coeliac disease or autoimmune gastritis), or certain medications can affect levels of iron, zinc, vitamin D, and B vitamins — all of which are important for healthy hair growth. True primary malabsorption directly caused by Sjögren's is less common and should not be assumed without investigation.
Autoimmune thyroid disease (such as Hashimoto's thyroiditis) commonly coexists with Sjögren's syndrome, and hypothyroidism is itself a well-established cause of diffuse hair thinning. It is therefore important to consider the full clinical picture rather than attributing hair loss to a single cause. Other common causes of hair loss — including androgenetic alopecia and postpartum shedding — may also coexist and should not be overlooked.

Regarding medications, hydroxychloroquine — commonly used in the management of Sjögren's syndrome — has alopecia and hair loss listed as adverse reactions of unknown frequency in its UK Summary of Product Characteristics (SmPC). Patients who notice hair changes after starting or changing a medicine should discuss this with their prescriber rather than stopping treatment abruptly. Suspected adverse drug reactions can be reported to the MHRA via the Yellow Card scheme (yellowcard.mhra.gov.uk).
| Cause / Type | Pattern of Hair Loss | Key Investigations | NHS Treatment Options |
|---|---|---|---|
| Systemic inflammation (Sjögren's disease activity) | Diffuse shedding; telogen effluvium | ESR, CRP, ANA, anti-Ro/SSA, anti-La/SSB | Hydroxychloroquine, immunosuppressants (methotrexate, mycophenolate) under rheumatology |
| Iron deficiency | Diffuse thinning; increased daily shedding | Ferritin (first-line); full blood count; coeliac serology if indicated | Oral iron supplementation; dietary optimisation |
| Autoimmune thyroid disease (e.g. Hashimoto's hypothyroidism) | Diffuse hair thinning across scalp | Thyroid function tests (TFTs) | Levothyroxine; hair often improves once thyroid levels stabilised |
| Alopecia areata (co-existing autoimmune condition) | Patchy, well-defined areas; may affect brows, lashes | Clinical assessment; dermatology referral; trichoscopy or biopsy if needed | Topical/intralesional corticosteroids; topical minoxidil (off-label); JAK inhibitors in specialist settings |
| Nutritional deficiencies (vitamin D, B12, zinc) | Diffuse thinning; brittle hair | Vitamin D, B12, folate levels where clinically indicated | Targeted supplementation; dietitian referral for xerostomia-related dietary difficulties |
| Drug-related (hydroxychloroquine) | Diffuse thinning; onset after starting or changing medication | Medication review; timeline correlation | Discuss with prescriber; do not stop abruptly; report via MHRA Yellow Card scheme |
| Scarring alopecia (e.g. frontal fibrosing alopecia, lichen planopilaris) | Progressive hairline recession; scarring on scalp | Urgent dermatology referral; scalp biopsy | Specialist management; early referral essential to prevent irreversible follicle loss |
Types of Hair Loss Associated with Sjögren's
Telogen effluvium is the most commonly reported type, presenting as diffuse shedding; alopecia areata, drug-related thinning, and scarring alopecias may also occur in the context of Sjögren's.
Understanding the type of hair loss a patient is experiencing is essential for guiding appropriate investigation and management. In the context of Sjögren's syndrome, several distinct patterns of hair loss may be observed.
Telogen effluvium is perhaps the most commonly reported type. This is a diffuse, non-scarring hair loss that occurs when a significant physiological or immunological stressor causes large numbers of hair follicles to enter the resting phase simultaneously. Patients typically notice increased shedding — often described as hair coming out in greater quantities when washing or brushing — rather than discrete bald patches. This pattern is frequently linked to systemic inflammation, nutritional deficiencies, or intercurrent illness.
Alopecia areata is an autoimmune condition in its own right, characterised by patchy, well-defined areas of hair loss. There is a recognised association between alopecia areata and other autoimmune diseases, including Sjögren's syndrome, as individuals with one autoimmune condition carry a higher risk of developing others. Alopecia areata can affect the scalp, eyebrows, eyelashes, and body hair.
Less commonly, patients may experience:
-
Diffuse alopecia related to autoimmune thyroid disease, which commonly coexists with Sjögren's syndrome
-
Drug-related hair thinning, potentially linked to hydroxychloroquine or immunosuppressive therapies
-
Frontal fibrosing alopecia or lichen planopilaris, scarring forms of hair loss that have been reported in association with autoimmune conditions; however, a direct causal link to Sjögren's has not been firmly established and these are not typical features of the condition
It is also important to consider common causes of hair loss that may coexist independently of Sjögren's, including androgenetic alopecia (pattern hair loss), traction alopecia from hairstyling practices, and — in children — tinea capitis. Distinguishing between these types requires careful clinical assessment, as the underlying cause will determine the most appropriate treatment pathway.
Diagnosis and Assessment in the UK
UK assessment begins with a GP consultation and blood tests including ferritin, thyroid function, full blood count, and autoantibody screen; dermatology or rheumatology referral follows based on findings.
In the UK, patients presenting with hair loss in the context of a known or suspected autoimmune condition such as Sjögren's syndrome should receive a structured assessment. The starting point is typically a consultation with a GP, who will take a detailed history covering the onset, pattern, and progression of hair loss, alongside a review of current medications, nutritional status, and any other systemic symptoms.
Blood tests form a cornerstone of initial investigation. In line with NHS and primary care guidance, the following are commonly considered:
-
Full blood count — to identify anaemia, which can contribute to hair loss
-
Ferritin (and transferrin saturation or TIBC if iron deficiency is suspected) — ferritin is the preferred first-line test for iron deficiency; serum iron alone is not recommended
-
Thyroid function tests (TFTs) — given the elevated prevalence of autoimmune thyroid disease in people with Sjögren's syndrome
-
Vitamin D, B12, and folate — considered where there are clinical features suggesting deficiency, dietary risk factors, or relevant gastrointestinal symptoms, rather than as a routine screen for all patients with hair loss
-
Coeliac serology — where iron deficiency or suggestive gastrointestinal symptoms are present
-
Inflammatory markers (ESR, CRP) — to help assess disease activity in the context of known or suspected Sjögren's
-
Autoantibody screen (ANA, anti-Ro/SSA, anti-La/SSB) — indicated where Sjögren's has not yet been formally diagnosed and clinical features support this possibility
Referral pathways will depend on findings. A GP may refer to a dermatologist for specialist assessment of the scalp and hair follicles, including trichoscopy or scalp biopsy where scarring alopecia is suspected. Early dermatology referral is particularly important if a scarring process is possible, as prompt assessment can prevent irreversible follicle loss. Patients with active or poorly controlled Sjögren's may be referred to or reviewed by a rheumatologist. In some NHS trusts, multidisciplinary clinics exist to coordinate care across specialties, which can be particularly beneficial for patients with complex autoimmune presentations.
Treatment Options Available on the NHS
Treatment is guided by the underlying cause and may include nutritional supplementation, topical or intralesional corticosteroids for alopecia areata, levothyroxine for hypothyroidism, and optimising Sjögren's disease management.
Treatment of hair loss in Sjögren's syndrome is guided by the underlying cause identified during assessment. There is no single universal treatment, and a personalised approach is essential.
Where nutritional deficiencies are identified, supplementation is the first-line intervention. Iron supplementation is commonly prescribed for iron-deficiency-related telogen effluvium, and vitamin D or B12 replacement may be recommended where levels are suboptimal. Correcting these deficiencies often leads to gradual improvement in hair density over several months.
For alopecia areata, NHS treatment options include:
-
Topical corticosteroids — applied directly to affected areas to reduce localised immune activity
-
Intralesional corticosteroid injections — administered by a dermatologist for more persistent patches
-
Topical minoxidil — available over the counter and sometimes used to support regrowth; however, its use in alopecia areata is off-label (it is licensed for androgenetic alopecia) and evidence for benefit in alopecia areata is modest; patients should seek dermatology advice before use
-
Contact immunotherapy and selected systemic treatments — reserved for extensive or refractory cases and managed in secondary care; newer systemic options, including JAK inhibitors, may be available in specialist settings subject to NICE guidance
Managing the underlying Sjögren's disease activity is also central to addressing hair loss. Hydroxychloroquine — an immunomodulatory agent used in Sjögren's syndrome primarily for musculoskeletal and skin symptoms — may indirectly benefit hair health by reducing systemic inflammation. However, as noted above, alopecia is listed as an adverse reaction in its SmPC; patients who notice hair changes whilst taking hydroxychloroquine should discuss this with their prescriber. In more severe cases, immunosuppressants such as methotrexate or mycophenolate mofetil may be used under rheumatological supervision. Patients should be aware that some immunosuppressive agents can themselves contribute to hair thinning, and the risks and benefits should be discussed with the prescribing specialist.
If autoimmune thyroid disease is identified as a contributing factor, appropriate thyroid hormone replacement (levothyroxine for hypothyroidism) is initiated by the GP or endocrinologist, and hair loss often improves once thyroid levels are stabilised. Patients should be counselled that hair regrowth following any treatment is typically gradual, often taking six to twelve months.
Managing Hair Loss Alongside Sjögren's Syndrome
A holistic approach combining gentle hair care, dietary optimisation, NHS wig services where eligible, and psychological support via NHS Talking Therapies is recommended for patients managing hair loss with Sjögren's.
Living with both Sjögren's syndrome and hair loss can have a significant impact on a patient's psychological wellbeing and quality of life. A holistic approach to management — addressing both the physical and emotional dimensions — is therefore important.
From a practical hair care perspective, patients are advised to:
-
Use gentle, sulphate-free shampoos and avoid harsh chemical treatments
-
Minimise heat styling, tight hairstyles, and excessive brushing, which can exacerbate fragile hair
-
Consider lightweight volumising products to improve the appearance of thinning hair
-
Scalp massage is a low-risk self-care measure that some patients find helpful; however, evidence that it meaningfully promotes hair regrowth is limited, and it should be regarded as a comfort measure rather than a treatment
NHS wig and hair replacement services may be available on prescription for patients with significant hair loss due to a medical condition; a GP or dermatologist can advise on eligibility.
Dietary support is an important self-management strategy. A balanced diet rich in protein, iron, omega-3 fatty acids, and antioxidants supports hair follicle health. Patients with Sjögren's who experience difficulty eating due to dry mouth or who have gastrointestinal symptoms should seek dietary advice from a registered dietitian, who can help optimise nutritional intake.
The psychological impact of hair loss should not be underestimated. Studies consistently show that hair loss — particularly in women — is associated with reduced self-esteem, anxiety, and depression. Patients should be encouraged to discuss these concerns openly with their healthcare team. Referral to a clinical psychologist or counsellor may be appropriate in some cases. NHS Talking Therapies services are accessible via GP referral and can provide cognitive behavioural therapy (CBT) for those experiencing significant distress.
Patient support organisations such as the British Sjögren's Syndrome Association (BSSA) offer valuable peer support, information resources, and signposting to specialist services, and can be a helpful complement to NHS care. The British Association of Dermatologists (BAD) also provides patient information leaflets on alopecia areata and other forms of hair loss.
When to Seek Further Advice from Your GP or Specialist
Seek GP advice promptly for sudden or patchy hair loss, scalp inflammation, new systemic symptoms, or suspected medication-related shedding; early dermatology referral is critical if scarring alopecia is possible.
Whilst some degree of hair shedding is a normal part of the hair growth cycle, certain features warrant prompt medical attention — particularly in the context of a known autoimmune condition such as Sjögren's syndrome.
Contact your GP if you notice:
-
Sudden or rapidly progressive hair loss over a period of weeks
-
Patchy bald areas on the scalp, eyebrows, or eyelashes
-
Scalp redness, scaling, itching, or tenderness, which may suggest an inflammatory or scarring process
-
Hair loss accompanied by new or worsening systemic symptoms such as fatigue, joint pain, or skin rashes
-
Signs of possible nutritional deficiency, including brittle nails, fatigue, or pallor
-
Significant emotional distress related to changes in hair or appearance
If you suspect that a prescribed medicine may be contributing to hair loss, discuss this with your GP or prescribing specialist before making any changes to your treatment. Do not stop immunosuppressive or other prescribed medicines abruptly, as this can carry risks. Suspected adverse drug reactions can be reported to the MHRA via the Yellow Card scheme (yellowcard.mhra.gov.uk).
Patients already under the care of a rheumatologist for Sjögren's syndrome should mention hair loss at their next review appointment, as it may indicate a change in disease activity or a need to reassess the current treatment regimen.
Early referral to a dermatologist is particularly important if a scarring alopecia (such as lichen planopilaris or frontal fibrosing alopecia) is suspected, as this form of hair loss can be irreversible if not treated promptly. Trichoscopy and scalp biopsy can provide a definitive diagnosis and guide targeted treatment.
In summary, hair loss in Sjögren's syndrome is a recognised but often overlooked feature of the condition. With timely assessment, appropriate investigation, and a coordinated approach to treatment, many patients can achieve meaningful improvement. Open communication with your healthcare team remains the most important step.
Frequently Asked Questions
Is hair loss a common symptom of Sjögren's syndrome?
Hair loss is a recognised but not universally common feature of Sjögren's syndrome — it is reported by some patients rather than the majority. It is not among the condition's hallmark symptoms (dry eyes and dry mouth), but systemic inflammation, nutritional deficiencies, and coexisting conditions such as autoimmune thyroid disease can all contribute to shedding.
Can hydroxychloroquine cause hair loss in people with Sjögren's?
Yes, alopecia is listed as an adverse reaction of unknown frequency in the UK Summary of Product Characteristics (SmPC) for hydroxychloroquine. If you notice hair changes after starting or adjusting hydroxychloroquine, speak to your prescriber before stopping the medication, as abrupt discontinuation carries its own risks.
What blood tests should I ask my GP for if I have Sjögren's and am losing hair?
Key blood tests include ferritin (for iron deficiency), thyroid function tests, full blood count, and vitamin D and B12 levels where deficiency is clinically suspected. If Sjögren's has not been formally diagnosed, an autoantibody screen including ANA, anti-Ro/SSA, and anti-La/SSB may also be appropriate.
What is the difference between telogen effluvium and alopecia areata in the context of Sjögren's?
Telogen effluvium causes diffuse, generalised shedding across the whole scalp, typically triggered by systemic stress such as inflammation or nutritional deficiency, whereas alopecia areata presents as distinct patchy bald areas and is itself an autoimmune condition. Both can occur in people with Sjögren's, but they have different causes and treatment pathways, so accurate diagnosis is important.
How do I get a referral to a dermatologist for hair loss on the NHS?
You can request a dermatology referral through your GP, who will assess your hair loss and refer you if specialist input is needed — particularly if a scarring alopecia or complex autoimmune pattern is suspected. Early referral is important for scarring forms of hair loss, as prompt treatment can prevent permanent follicle damage.
How long does it take for hair to grow back after treating the cause of hair loss in Sjögren's syndrome?
Hair regrowth following treatment — whether for nutritional deficiency, hypothyroidism, or alopecia areata — is typically gradual and may take six to twelve months to become noticeable. Non-scarring forms of hair loss generally carry a better prognosis for regrowth than scarring alopecias, where follicle damage may be permanent if treatment is delayed.
