Maintaining a healthy scalp is essential when you have alopecia areata because it creates the best possible environment for regrowth once the immune response subsides. While scalp care alone does not cure the autoimmune process, neglecting the scalp during active hair loss can lead to secondary issues like dryness, irritation, and increased sensitivity that complicate treatment and recovery.
This article is for informational purposes only and does not constitute medical advice.
Why Scalp Health Matters in Alopecia Areata
Alopecia areata puts hair follicles into a dormant state rather than destroying them. This is important because it means the follicles retain the ability to produce hair again. Keeping the scalp environment healthy while follicles are dormant supports their readiness to resume growth when the immune attack resolves.
A compromised scalp can also interfere with topical treatments. If the skin barrier is damaged by dryness, irritation, or excess buildup, medications like topical corticosteroids and minoxidil may not absorb effectively. Scalp inflammation from secondary causes such as seborrheic dermatitis can also worsen the overall inflammatory burden on the scalp.
Daily Scalp Care Routine
Cleansing
Wash your scalp 2 to 3 times per week with a gentle, sulfate-free shampoo. Over-washing strips the scalp of natural oils, while under-washing allows buildup of sebum and dead skin cells that can clog follicles.
For bare patches specifically:
- Use lukewarm water rather than hot water, which can dry out exposed skin
- Apply shampoo with fingertips using gentle circular motions
- Avoid scrubbing or scratching bare patches, even if they feel itchy
- Rinse thoroughly to remove all product residue
If your dermatologist has prescribed a medicated shampoo containing ketoconazole or selenium sulfide, follow their instructions on frequency and contact time.
Moisturizing
Exposed scalp skin in alopecia areata patches is more vulnerable to dryness than hair-covered areas. Apply a lightweight, fragrance-free moisturizer or scalp serum to bare patches after washing. Look for products containing:
- Hyaluronic acid: Draws moisture into the skin
- Ceramides: Strengthen the skin barrier
- Niacinamide: Reduces inflammation and supports barrier function
- Aloe vera: Soothes irritation without clogging pores
Avoid heavy oils or petroleum-based products on bare patches, as these can create a barrier that interferes with topical treatments applied later.
Sun Protection
Bare scalp patches have no natural UV protection from hair. Sun damage to exposed skin can cause inflammation that adds to the autoimmune burden on the scalp.
Protect bare patches by:
- Applying SPF 30 or higher broad-spectrum sunscreen formulated for the face or scalp
- Wearing a hat or head covering when spending extended time outdoors
- Reapplying sunscreen every 2 hours during prolonged sun exposure
- Choosing mineral (zinc oxide or titanium dioxide) sunscreens if your skin is sensitive
Sunburn on alopecia areata patches can be particularly painful and may trigger a Koebner-like response, potentially worsening or spreading the condition.
Products and Ingredients to Avoid
Certain scalp care products can irritate already sensitive skin or interfere with treatment.
| Avoid | Why |
|---|---|
| Sulfates (SLS/SLES) | Strip natural oils, cause dryness and irritation |
| Heavy fragrances | Can trigger contact dermatitis on sensitive bare patches |
| Alcohol-based products | Dry out the scalp and damage the skin barrier |
| Essential oils (undiluted) | Risk of allergic reactions and contact dermatitis |
| Harsh chemical treatments | Dyes, relaxers, and perms stress remaining hair |
| Tight hairstyles | Traction on remaining hair can cause additional loss |
If you are using prescribed topical treatments like corticosteroids or minoxidil, apply these to clean, dry skin before layering any cosmetic scalp products. Wait at least 30 minutes between medicated and cosmetic products to allow proper absorption.
Scalp Massage and Circulation
Gentle scalp massage may support hair health by increasing blood flow to the follicles. A 2019 study found that standardized scalp massage over 24 weeks improved hair thickness in participants, though the research was focused on androgenetic alopecia rather than alopecia areata specifically.
How to Massage Safely
Use your fingertips, not your nails, and apply light to moderate pressure. Spend 3 to 5 minutes per session, working across the entire scalp including bare patches. Perform the massage on dry scalp or during shampooing.
Avoid using electronic scalp massagers with sharp bristles on bare patches, as these can irritate the exposed skin. Manual massage with clean fingertips is the safest approach.
Managing Common Scalp Issues
Itching in Bare Patches
Itching is common in alopecia areata and can indicate active disease or early regrowth. Resist the urge to scratch, which can damage the skin and any new fine hairs emerging. Cool compresses, calamine-based products, or an over-the-counter hydrocortisone cream (1%) can provide temporary relief. If itching is persistent, discuss it with your dermatologist, as it may warrant prescription treatment.
Folliculitis
Small red bumps or pustules around follicle openings can develop, particularly if you are using occlusive products. Keep the scalp clean, avoid heavy products on affected areas, and see your dermatologist if pustules persist for more than a week.
Dryness and Flaking
Bare patches are prone to dryness and flaking, especially in cold or dry climates. Regular moisturizing and avoiding harsh cleansers will address most cases. If flaking is severe and accompanied by redness and greasiness, it may indicate seborrheic dermatitis, which requires separate treatment.

When Regrowth Begins
New hair growth in alopecia areata patches often starts as fine, white or light-colored vellus hair before gradually thickening and returning to its normal color and texture. This process can take several months. During regrowth:
- Continue your scalp care routine without changes
- Be gentle with new growth, as the hair is fragile
- Avoid pulling or tugging on fine regrowth hairs
- Continue any prescribed treatments unless your dermatologist advises otherwise
Do not assume the condition is resolved because of initial regrowth. Alopecia areata can recur, and maintaining good scalp health along with treatment adherence is important for long-term management.
Creating Your Scalp Care Plan
Work with your dermatologist to build a scalp care routine that complements your medical treatment plan. The specific products and frequency that work best for you will depend on your skin type, the extent of hair loss, and which medications you are using. Bring a list of all scalp products you currently use to your next appointment so your doctor can flag any potential interactions or irritants.
If you are unsure about the extent of your hair loss, a hair transplant candidacy assessment can help clarify your current stage.
