Your Scalp Problem: What It Is & How to Treat It

What's Actually Going On

1. Seborrheic Dermatitis (most likely) - a chronic condition caused by overgrowth of a yeast called Malassezia on your scalp. It causes greasy/thick scales, itching, and redness. Very common in teens.
2. Scalp Psoriasis - causes thick silvery-white plaques with bleeding when scratched ("Auspitz sign" = blood on removed scale is classic).
3. Scalp Folliculitis - the tiny pimples you see on your head are inflamed hair follicles, often from fungal/bacterial overgrowth or scratching.

⚠️ Important: Because you have bleeding and pimples alongside flakes, please see a dermatologist to confirm the diagnosis. A doctor can prescribe stronger treatments if needed.

Pharmacy Shampoos - What to Buy

Tier 1 - Use First (Antifungal - tackles the root cause)

Tier 2 - Add for Scale Removal

Smart Rotation Strategy

• Day 1 (e.g., Monday): Ketoconazole shampoo - leave 5-10 mins
• Day 2 (e.g., Thursday): Zinc pyrithione or selenium sulfide
• Wash hair every 2-3 days during a flare (don't go longer - oil feeds the yeast)

Application Technique (Important!)

1. Apply directly to scalp, not just hair
2. Massage gently with fingertips - never use nails (causes bleeding and worsens folliculitis)
3. Leave on for 5-10 minutes (don't rinse immediately)
4. Rinse thoroughly
5. Follow with a gentle, fragrance-free conditioner on the hair lengths (not scalp)

If the Shampoo Doesn't Work / For the Pimples

• Ketoconazole 2% shampoo (stronger, prescription)
• Hydrocortisone 1% lotion for short-term use on scalp (reduces inflammation and bleeding)
• Oral terbinafine 250 mg/day for 4 weeks - for moderate-to-severe seborrhea (textbook-proven, SOR: A evidence)
• For folliculitis (scalp pimples): topical or oral antibiotics

Foods That Help (Anti-Inflammatory Diet)

Eat More Of:

• Omega-3 rich foods - fatty fish (salmon, mackerel, sardines), flaxseeds, walnuts. These reduce scalp inflammation.
• Zinc-rich foods - pumpkin seeds, chickpeas, lentils, eggs, lean meat. Zinc deficiency worsens dandruff.
• Probiotics - yogurt, curd (dahi), fermented foods like idli/dosa batter. Good gut bacteria help control Malassezia overgrowth.
• Vitamin B6 & B12 - whole grains, eggs, dairy, leafy greens
• Biotin - eggs, nuts, sunflower seeds, sweet potato
• Green leafy vegetables - spinach, methi, kale (antioxidants reduce skin inflammation)
• Vitamin D - sunlight exposure for 15 min/day, eggs, fortified milk (low Vitamin D is linked to worse seborrheic dermatitis)

Cut Down On:

• Sugary foods and drinks - sugar feeds yeast (Malassezia thrives on sugar)
• Refined carbs - white bread, maida, biscuits - spike insulin and trigger skin inflammation
• Junk and fried food - excess oil worsens seborrhea
• Dairy overload - some people with scalp issues find reducing dairy helps (not universal, test it for yourself)
• Alcohol - worsens seborrheic dermatitis significantly

Daily Scalp Care Routine

Do:

• Wash every 2-3 days during active flares (not less - oil buildup feeds yeast)
• Use lukewarm water - hot water dries and irritates the scalp further
• Clip fingernails short - prevents scratching and opening wounds (the source of bleeding)
• Dry hair properly - fungus thrives in a damp scalp. Pat dry with a soft towel, allow to air dry
• Use a soft wide-tooth comb to gently remove loosened scales (after shampooing, never dry)
• Change pillowcase every 2-3 days - fungal spores accumulate on pillow fabric
• Stay hydrated - 8-10 glasses of water daily for healthy skin

Don't:

• Don't scratch - this causes the bleeding and worsens folliculitis (infection of scalp pimples)
• Don't use heavy oils like coconut oil or almond oil directly on the scalp during active flares - oil feeds Malassezia
• Don't use strong chemical hair products - hairsprays, dry shampoos, gels trap yeast and irritate follicles
• Don't share combs/towels - folliculitis can spread
• Don't use heat tools (straighteners, blow dryers on hot) during flare-ups - they dry and damage already irritated skin

For the Scalp Pimples (Folliculitis) Specifically:

• Apply diluted tea tree oil (3-4 drops in 2 tablespoons of water, or mix into your shampoo) - it has antifungal and antibacterial properties that help folliculitis
• Keep hands away from scalp
• If pimples become painful, larger, or pus-filled - see a doctor immediately (bacterial folliculitis needs antibiotic treatment)

Stress & Sleep

• Stress is a major trigger for both seborrheic dermatitis and psoriasis. Cortisol spikes worsen skin inflammation directly.
• Aim for 7-8 hours of sleep - skin repairs itself at night
• Exercise helps too - sweat cleanly (rinse scalp after working out, don't let sweat sit on scalp for hours)
