Scalp Care in Summer: Tips and home remedies to prevent dandruff and hair fall

The scalp is a unique environment with abundant sebaceous glands that produce oil, which increases in summer due to heat and humidity. Combined with sweat, this can lead to clogged follicles, irritation, and even fungal growth. Sun exposure can also cause burns, dryness, and long-term damage, especially in areas with thin or parted hair. Proper scalp care in summer helps prevent issues like dandruff, inflammation, and potential hair loss. Here’s a comprehensive guide to keeping your scalp clean and free from dandruff and reducing hair fall during summer.

Common summer scalp concerns

Sunburn- the scalp, along part lines or in thinning areas, is prone to UV damage.

Excess oil and sweat- heat stimulates oil glands and sweat can mix with dirt and bacteria leading to greasiness or odour.

Dryness and flaking- frequent washing to combat sweat can strip the scalp of natural oils causing flakiness.

Fungal infection- warm, moist conditions are a breeding ground for fungi like Malassaezia which can worsen dandruff or cause itchiness

Hair damage- UV rays don't just harm the scalp, they weaken hair cuticles, making strands brittle and prone to breakage.

Dermatologist recommended tips for summer scalp care

1. Sun protection is non-negotiable

• According to Dr. Viral Desai, Board certified super specialist, cosmetic plastic and hair transplant surgeon and Medical Director – DHI India, “Use a Hat or Scarf: A wide-brimmed hat or UV-protective cap is your first line of defense. Look for breathable fabrics like cotton to avoid trapping heat.”
• Apply Sunscreen: For exposed areas (part lines, thinning spots), use a broad-spectrum SPF 30+ sunscreen. Opt for lightweight, non-greasy formulas—sprays or gels work well for the scalp. Reapply every two hours if you’re outdoors for long periods or after swimming.
• Timing: Minimize direct sun exposure between 10 a.m. and 4 p.m., when UV rays are strongest.



2. Cleanse smartly
• Shampoo Regularly: Wash your hair 2-3 times a week (or more if you sweat heavily) with a gentle, sulfate-free shampoo to remove sweat, oil, and debris without over-drying. Look for ingredients like tea tree oil or salicylic acid if you’re prone to oiliness or flaking.
• Avoid Overwashing: Daily washing can strip the scalp, so balance cleansing with your scalp’s natural needs. If you’re sweaty but don’t want a full wash, rinse with water and use a small amount of conditioner on the ends.

3. Hydrate and soothe
• Condition Properly: Use a lightweight conditioner on the mid-lengths and ends of your hair, avoiding the scalp unless it’s specifically formulated for scalp hydration (e.g., with aloe vera or hyaluronic acid).
• Cool Rinse: After shampooing, finish with a cool water rinse to close hair cuticles and calm the scalp.
• Scalp Masks : Once a week, try a soothing mask with ingredients like oatmeal, chamomile, or peppermint to reduce irritation and hydrate.

4. Combat fungal growth
• Antifungal Shampoo : If you notice persistent itching or flakes, use an over-the-counter shampoo with ketoconazole, zinc pyrithione, or selenium sulfide once or twice a week. Rotate it with your regular shampoo.
• Keep it Dry: After swimming or sweating, dry your scalp thoroughly—fungi thrive in dampness.

5. Watch your diet and hydration
• Stay Hydrated: Drinking plenty of water supports overall skin health, including the scalp.
• Nutrient Boost: Foods rich in omega-3s (like salmon), zinc (nuts, seeds), and vitamins A and E (leafy greens, avocados) promote a healthy scalp and hair growth.

6. Keep scalp clean

According to Dr. Geeta Sajid Fazalbhoy Dermatologist (MBBS, DPD UK, AAAM USA), Managing Director & Founder of Skin & You Clinic, Nariman Point, Mumbai, “Wash hair with an oil control shampoo containing ketoconazole and zinc pyrithrione; use shampoo as needed; dry hair well after shampooing; do not tie wet hair. Avoid caps and head covers this season. Use shampoo like Foltene Sebo Control Shampoo, Onabet Anti-Dandruff Shampoo, or Neutrogena T-Gel Shampoo. Avoid highly sugary foods and drink more water.”

7. Limit heat styling
• Blow dryers, straighteners, and curling irons exacerbate dryness in summer. Air-dry when possible, and if you must style, use a heat protectant spray.

When to see your Dermatologist:
If you experience persistent itching redness scaling or hair loss that does not improve with basic care, it's time to see your dermatologist. Conditions like seborrheic dermatitis, psoriasis or even early signs of UV-induced damage might need targeted treatments like medicated shampoos, topical steroids or a professional evaluation.
