Living with eczema can be challenging, with symptoms ranging from itchy, inflamed skin to more complex complications. For many people dealing with eczema on the scalp, a concerning question often arises: can this skin condition lead to hair loss? This comprehensive guide explores the relationship between eczema and hair loss, providing evidence-based information to help you understand and manage this potential complication.

Can Eczema Cause Hair Loss?
Yes, eczema can cause hair loss, particularly when it affects the scalp. The condition itself doesn't directly cause hair follicles to stop producing hair, but the inflammation, itching, and subsequent scratching associated with scalp eczema can damage hair follicles and lead to temporary hair loss. This type of hair loss is usually reversible once the eczema is properly treated and controlled.

Understanding Eczema and Its Impact on the Scalp
Eczema, medically known as atopic dermatitis, is a chronic inflammatory skin condition characterized by dry, itchy, and irritated skin. When eczema affects the scalp, it's often referred to as seborrheic dermatitis or scalp eczema.
Common Symptoms of Scalp Eczema
Scalp eczema typically presents with these symptoms:
- Redness and inflammation
- Intense itching
- Dry, flaky skin (similar to dandruff but more severe)
- Greasy or waxy patches
- Crusting or oozing in severe cases
- Burning or soreness
The Connection Between Scalp Eczema and Hair Loss
While eczema itself doesn't directly cause permanent hair loss, several factors related to the condition can contribute to temporary hair shedding:
Inflammation and Hair Follicle Damage
Chronic inflammation from eczema can affect the health of hair follicles. When inflammation persists around hair follicles, it can disrupt the normal hair growth cycle, potentially leading to increased shedding and temporary thinning of hair.
Scratching and Physical Trauma
Perhaps the most significant factor linking eczema to hair loss is the intense itching that accompanies the condition. Persistent scratching can cause physical trauma to the scalp and hair follicles, leading to:
- Broken hair shafts
- Weakened hair roots
- Damage to follicles that can impair new hair growth
- Secondary bacterial infections that worsen inflammation
Stress-Related Hair Loss
Living with chronic eczema can cause significant psychological stress. This stress can trigger or exacerbate a type of hair loss called telogen effluvium, where hair prematurely enters the shedding phase of the growth cycle.
Types of Hair Loss Associated with Eczema
Several types of hair loss can occur in conjunction with eczema:
Telogen Effluvium
This temporary form of hair loss occurs when stress or illness pushes a large number of hair follicles into the resting phase, resulting in increased shedding. The stress of dealing with chronic eczema can trigger this condition.
Traction Alopecia
Constant scratching and rubbing of the scalp can lead to this form of hair loss, where physical trauma damages hair follicles.
Secondary Alopecia Areata
In some cases, the autoimmune response associated with eczema may trigger alopecia areata, causing patchy hair loss. Research suggests a potential link between these two autoimmune-related conditions.
Diagnosing Eczema-Related Hair Loss
If you're experiencing hair loss and suspect it may be related to eczema, it's important to get a proper diagnosis. Healthcare providers typically:
- Examine the scalp for signs of eczema and inflammation
- Assess the pattern and extent of hair loss
- May take a skin scraping or biopsy in unclear cases
- Rule out other potential causes of hair loss like fungal infections or other autoimmune conditions
Treating Eczema to Prevent Hair Loss
The key to preventing eczema-related hair loss is effectively managing the underlying eczema. Treatment approaches typically include:
Topical Treatments
These are first-line treatments for scalp eczema:
- Corticosteroid solutions or foams to reduce inflammation
- Calcineurin inhibitors like tacrolimus or pimecrolimus for steroid-free treatment
- Coal tar preparations to slow skin cell growth and reduce scaling
- Antifungal treatments if yeast is contributing to the condition
Medicated Shampoos
Several types of medicated shampoos can help manage scalp eczema:
- Ketoconazole shampoos to combat yeast overgrowth
- Coal tar shampoos to reduce inflammation and flaking
- Salicylic acid formulations to help remove scales
- Zinc pyrithione products to fight fungi and bacteria
Systemic Treatments
For severe cases, oral medications may be necessary:
- Oral corticosteroids for short-term management of severe flares
- Immunosuppressants like cyclosporine or methotrexate for persistent cases
- Biologic medications that target specific parts of the immune system
Phototherapy
Controlled exposure to UVB light can help reduce inflammation and improve symptoms in some cases of scalp eczema.
Home Remedies and Self-Care for Scalp Eczema
In addition to medical treatments, several self-care strategies can help manage scalp eczema and reduce the risk of hair loss:
Gentle Hair Care Practices
- Use lukewarm (not hot) water when washing hair
- Choose gentle, fragrance-free shampoos
- Avoid harsh styling products, dyes, and chemicals
- Let hair air dry rather than using hot blow dryers
- Use wide-toothed combs and avoid excessive brushing
Moisturizing the Scalp
- Apply natural oils like coconut oil or jojoba oil to soothe the scalp
- Use hypoallergenic moisturizers specifically formulated for sensitive skin
- Consider aloe vera gel for its anti-inflammatory properties
Itch Management Techniques
- Apply cold compresses to reduce itching sensation
- Keep fingernails short to minimize damage from scratching
- Try wearing cotton gloves at night if you scratch in your sleep
- Use over-the-counter antihistamines to reduce itching
Dietary Considerations
- Identify and avoid food triggers that may worsen eczema
- Consume foods rich in omega-3 fatty acids (fish, flaxseed, walnuts)
- Stay hydrated to maintain skin moisture
- Consider probiotics to support immune function
When Will Hair Grow Back After Eczema-Related Loss?
The timeline for hair regrowth after eczema-related hair loss varies depending on several factors:
- The severity and duration of the eczema flare
- The extent of follicle damage from scratching
- How quickly the eczema is brought under control
- Individual hair growth cycles
In most cases, once the eczema is effectively treated and inflammation is reduced, hair typically begins to regrow within 3-6 months. The normal hair growth cycle takes time, so patience is important. Complete regrowth may take 12-18 months in some cases.
When to See a Doctor
Consult a healthcare provider if you experience:
- Severe or worsening scalp eczema that doesn't respond to over-the-counter treatments
- Significant hair loss that continues despite eczema treatment
- Signs of infection (increased redness, warmth, swelling, pus, or fever)
- Sudden onset of patchy hair loss
- Scalp symptoms accompanied by other concerning symptoms
Eczema vs. Other Causes of Hair Loss
It's important to distinguish eczema-related hair loss from other potential causes:
Psoriasis
Similar to eczema but typically presents with thicker, silvery scales and well-defined patches.
Fungal Infections
Conditions like tinea capitis (scalp ringworm) can cause scaly patches and hair loss, often with broken hairs and black dots.
Alopecia Areata
An autoimmune condition causing smooth, round patches of hair loss without scalp inflammation or scaling.
Pattern Hair Loss
Genetic hair loss follows predictable patterns and typically doesn't involve scalp inflammation or itching.
Living with Scalp Eczema: Long-term Management
Managing scalp eczema and preventing related hair loss is often a long-term commitment. Consider these strategies:
- Work with dermatologists who specialize in both skin and hair disorders
- Keep a symptom diary to identify triggers
- Develop a maintenance routine for periods of remission
- Join support groups to connect with others experiencing similar challenges
- Address stress through mindfulness, meditation, or therapy
- Consider professional counseling if hair loss affects your self-esteem and mental health
Conclusion
While eczema can indeed contribute to hair loss, particularly when it affects the scalp, this hair loss is typically temporary and reversible with proper treatment. The key to preventing and addressing eczema-related hair loss lies in controlling inflammation, avoiding scratching, and maintaining good scalp health. With appropriate medical intervention and consistent self-care, most people can effectively manage scalp eczema and minimize its impact on hair growth. If you're struggling with scalp eczema and hair loss, don't hesitate to consult a dermatologist who can provide personalized treatment recommendations based on your specific symptoms and needs.
