Which Autoimmune Diseases Cause Hair Loss, and How It Looks

Hair loss can be stressful, especially when it stems from an underlying autoimmune condition. Autoimmune diseases occur when the body’s defense system mistakenly attacks healthy tissues. In some cases, this attack targets hair follicles or related structures, leading to noticeable thinning or bald patches. Below, we explore the most common conditions, their typical hair‐loss patterns, and steps you can take to seek help.

1. Alopecia Areata

• Description: A classic autoimmune disorder in which the immune system attacks hair follicles.
• Hair‐loss pattern:

• Sudden, round or oval smooth patches of baldness on the scalp, beard, or body
• May progress to total scalp loss (alopecia totalis) or whole‐body loss (alopecia universalis)
  • Onset: Any age, often in childhood or young adulthood
  • Additional signs: Itching or tingling in affected areas is possible before hair falls out

2. Systemic Lupus Erythematosus (Lupus)

• Description: Lupus causes widespread inflammation and can affect skin, joints, kidneys, and hair follicles.
• Hair‐loss pattern:

• Diffuse thinning across the scalp rather than distinct patches
• “Lupus hair”: Fine, brittle, broken hairs along the frontal hairline
• Red, scaly rash on the scalp in areas of active disease
  • Onset: Women of childbearing age are most commonly affected
  • Additional signs: Fatigue, joint pain, sun‐sensitive rash, oral ulcers

3. Hashimoto’s Thyroiditis and Graves’ Disease

Thyroid autoimmunity disrupts hormone balance, impacting the hair growth cycle.

Hashimoto’s Thyroiditis (Hypothyroidism)

• Description: Immune‐mediated destruction of the thyroid gland leads to low thyroid hormone.
• Hair‐loss pattern:

• Gradual, diffuse thinning on the scalp
• Coarser or dryer hair texture before shedding
  • Onset: Middle age, more common in women
  • Additional signs: Fatigue, weight gain, cold intolerance, dry skin

Graves’ Disease (Hyperthyroidism)

• Description: Immune factors overstimulate the thyroid, causing excess hormone.
• Hair‐loss pattern:

• Generalized thinning rather than complete bald spots
• Increased hair shedding during combing or washing
  • Onset: Often occurs in women aged 20–40
  • Additional signs: Weight loss, heat intolerance, rapid heartbeat, tremors

4. Lichen Planopilaris

• Description: A rare inflammatory condition affecting hair follicles on the scalp.
• Hair‐loss pattern:

• Scarring patches (permanent hair loss) with redness and scaling
• Follicular hyperkeratosis (small bumps around hair follicles)
  • Onset: Typically middle‐aged adults, more common in women
  • Additional signs: Itching, burning or pain in affected areas

5. Psoriasis

• Description: Immune cells trigger inflamed, scaly skin plaques; can affect the scalp.
• Hair‐loss pattern:

• Temporary shedding along the edges of thick, silvery plaques
• Regrowth usually occurs once inflammation eases
  • Onset: Often develops in early adulthood
  • Additional signs: Itchy or sore plaques on elbows, knees, lower back

6. Scleroderma (Localized and Systemic)

• Description: Overproduction of collagen leads to skin tightening and sometimes vascular damage.
• Hair‐loss pattern:

• Localized loss where skin is thickened and hardened
• Diffuse thinning if systemic involvement reduces blood flow to the scalp
  • Onset: Adults aged 30–50
  • Additional signs: Skin stiffness, Raynaud’s phenomenon (cold‐induced finger color changes)

7. Dermatomyositis

• Description: Inflammatory disease marked by muscle weakness and skin rash.
• Hair‐loss pattern:

• Diffuse thinning accompanying red or purple rash on the scalp and face
  • Onset: Can affect children or adults
  • Additional signs: Muscle weakness, Gottron’s papules (bumps over finger joints)

8. Celiac Disease

• Description: Autoimmune reaction to gluten that damages the small intestine.
• Hair‐loss pattern:

• Diffuse thinning due to nutrient malabsorption (iron, zinc, biotin)
  • Onset: Any age; often in childhood or early adulthood
  • Additional signs: Diarrhea, weight loss, abdominal pain, fatigue

How Autoimmune‐Related Hair Loss Looks

Autoimmune hair loss can vary widely, but some common characteristics include:

• Sudden vs. Gradual
  Alopecia areata often strikes rapidly, while thyroid‐related thinning develops over months.
• Pattern
  Patchy (alopecia areata, lichen planopilaris) vs. diffuse thinning (lupus, thyroid disorders, celiac).
• Scarring vs. Non‐scarring
  Scarring forms (lichen planopilaris, advanced lupus) result in permanent loss, non‐scarring forms often allow regrowth.
• Associated Skin Changes
  Scaling, redness, or bumps may point to conditions like psoriasis or lupus.

Diagnosing the Cause

A proper diagnosis helps guide treatment. Typical steps include:

1. Medical and family history: Autoimmune conditions often run in families.
2. Physical exam: Inspection of the scalp, nails, and any skin rashes.
3. Blood tests:
   • Autoantibodies (ANA, anti‐thyroid peroxidase, anti‐transglutaminase)
   • Thyroid hormone levels (TSH, free T4)
   • Nutrient levels (iron, zinc, vitamin D, biotin)
4. Scalp biopsy: In scarring cases, a small sample helps distinguish lichen planopilaris, lupus, or scleroderma.
5. Pull test and trichoscopy: Non‐invasive methods to assess shedding and follicle health.

Treatment Approaches

While each autoimmune disease has its specific management, some general strategies include:

• Medications
  • Topical or intralesional corticosteroids for localized autoimmune attacks (alopecia areata, lichen planopilaris)
  • Systemic immunosuppressants (methotrexate, hydroxychloroquine) for widespread disease (lupus, dermatomyositis)
  • Thyroid hormone replacement or antithyroid medications for Hashimoto’s or Graves’ disease
• Biologic therapies
  Targeted treatments such as JAK inhibitors (for alopecia areata)
• Nutritional support
  Correct deficiencies of iron, zinc, vitamin D, and biotin
• Lifestyle adjustments
  Stress management, gentle hair care, avoiding harsh chemicals or tight hairstyles

When to Seek Professional Help

Hair loss linked to an autoimmune disease can signal more widespread inflammation. If you experience any of the following, consider evaluation:

• Rapid hair loss lasting more than a few weeks
• New joint pain, fatigue, or skin rashes
• Symptoms of thyroid imbalance (weight change, heat/cold intolerance)
• Digestive issues (chronic diarrhea, unexplained weight loss)

Moving Forward

Understanding which autoimmune diseases cause hair loss—and how they present—can empower you to seek timely care. Early diagnosis and tailored treatment often improve outcomes and, in many cases, allow hair regrowth.

If you have concerns about hair loss or any potentially serious symptoms, speak to a doctor. Prompt medical advice is crucial for life-threatening or rapidly progressing conditions.
