Understanding Sjogren's Syndrome and Hair Loss
Sjogren's syndrome is an autoimmune disorder that affects moisture-producing glands in the body. This includes the tear glands and salivary glands, leading to dry eyes and dry mouth. However, Sjogren's syndrome can sometimes also lead to hair loss or alopecia.
What Causes Hair Loss in Sjogrens Syndrome?
The exact reasons why Sjogren's syndrome triggers hair loss are not fully understood. Research suggests that it is the autoimmune response itself that leads to damage of the hair follicles and disruption of the hair growth cycle. Some theories behind hair loss in Sjogrens patients include:
- Inflammation around the hair follicles caused by autoimmunity
- Vasculitis reducing blood flow to hair follicles
- Fibrosis or scarring of hair follicle tissue
Types of Hair Loss in Sjogrens
Hair loss caused by Sjogrens can manifest in different patterns. Some common types include:
Diffuse Non-Scarring Alopecia
This is also called telogen effluvium in medical terminology. It causes diffuse thinning all over the scalp due to an abnormal percentage of hairs being in the resting phase at any one time.
Alopecia Areata
This type causes round bald patches on the scalp and sometimes complete hair loss. It is caused by localized inflammation around hair follicles.
Frontal Fibrosing Alopecia
In this type, hair loss occurs mainly in the frontal hairline region of the scalp and is accompanied by scarring of hair follicles that prevents regrowth.
Underlying Disease Mechanisms
Sjogren's syndrome is an autoimmune condition, which means that the immune system starts attacking the body's own tissues rather than external pathogens. The reasons why this occurs are complex:
Genetic Predisposition
Research shows that certain genes can make someone more susceptible to developing Sjogren's syndrome. But genes alone do not determine everything.
Trigger Factors
It is thought that in genetically susceptible individuals, some trigger like a virus or bacteria could spark off the abnormal autoimmune reaction behind Sjogren's. Stress and hormonal changes could also play a role.
Loss of Self-Tolerance
Normally the immune system can discriminate between foreign threats and the body's own cells. But in Sjogren's, this loss of self-tolerance leads immune cells to attack glands and tissues like the hair follicles.
Risk Factors for Hair Loss
Not all Sjogren's patients experience alopecia or baldness. Some factors that seem to increase risk include:
- Having primary Sjogren's syndrome rather than just secondary disease
- More severe dry eye or dry mouth symptoms
- Presence of certain autoantibodies like Anti-Ro and Anti-La
- T lymphocytes abnormalities which are immune cells driving inflammation
- Coexisting thyroid disorders or skin conditions
Diagnostic Evaluation
Doctors use investigations like blood tests and lip biopsies to confirm underlying Sjogren's syndrome in those complaining of dryness along with hair loss. This establishes a definitive link between the two. Sometimes skin biopsies of bald patches can also aid diagnosis.
Treatment and Management
Treating the autoimmune basis of the disease is key to stopping progression of hair loss. Some common medications for moderate to severe Sjogren's include:
Corticosteroids
Steroids help calm inflammation but long-term use has side effects.
Hydroxychloroquine
This modifies immune system functioning and research shows efficacy in Sjogren's related hair loss.
Mycophenolate Mofetil
This immunosuppressant specifically targets damaging lymphocytes and improves fatigue and joint pain too.
Biologics like Rituximab
Rituximab works by reducing B lymphocytes that produce harmful autoantibodies in Sjogren's.
Topical Immunotherapies
Agents like topical steroids, minoxidil, irritants, and immunotherapy creams can also improve localized hair loss.
Supportive Measures Matter Too
While dealing with the autoimmune process is key, certain supportive strategies can further aid hair regrowth and improve quality of life with alopecia:
- Stress management via counseling, yoga, meditation etc
- Hair care practices like avoiding trauma from brushing or heat styling
- camouflaging products like scalp makeup and hair fibers
- Wigs if necessary for coping with appearance
- Joining support groups to share experiences and tips
The Takeaway
Hair loss stemming from autoimmune Sjogrens syndrome can be distressing but is manageable. Getting an accurate diagnosis and controlling disease activity are crucial to prevent progression of alopecia. While research on treating Sjogrens related hair loss is still evolving, using immunomodulators alongside hair growth promoters and supportive strategies often brings the best outcome.
FAQs
Does having Sjogren's syndrome always lead to hair loss?
No, hair loss or alopecia only occurs in a subset of Sjogren's patients. Factors like having primary Sjogren's, more severe dryness, and certain autoantibodies increase risk but do not make hair loss inevitable.
What pattern of baldness is most common with Sjogren’s related alopecia?
Diffuse non-scarring hair loss known as telogen effluvium is most typical. This causes hair thinning all over the scalp rather than distinct bald patches that are seen in alopecia areata.
Can hair lost from Sjogren’s syndrome grow back?
Yes, controlling the autoimmune inflammation should help hair regrow, especially if scarring has not already permanently damaged follicles. Topical hair stimulating drugs can further aid regrowth.
Which medications treat both Sjogren’s symptoms and hair loss?
Hydroxychloroquine and immunosuppressants like mycophenolate mofetil or rituximab are systemic Sjogren’s medications that research shows can also improve associated alopecia by calming autoimmunity.
