You are not imagining your scalp symptoms. Sensitive scalps itch, sting, flake, and sometimes shed hair, and it can be hard to know where to start. I will walk you through what is safe to try at home, when your primary care clinician is the right next step, and when a dermatologist adds real value. Along the way I will give you practical steps and a simple table you can screenshot for later.


What is a “sensitive scalp” and why does it happen?

A sensitive scalp is a pattern of symptoms that includes burning, tightness, itch, flaking, and tenderness. These sensations can be triggered by skin conditions such as dandruff, seborrheic dermatitis, psoriasis, contact dermatitis, folliculitis, or ringworm. Dandruff alone affects roughly half of adults worldwide, which explains why so many people struggle with flakes during their lifetime.¹ Seborrheic dermatitis, which is a related inflammatory condition with redness and thicker scaling, affects about 4.4% of people globally, with variation by age and region.²


How do I decide between self-care, primary care, and a dermatologist?

Think of the decision as three lanes. Start with the lane that fits your current symptoms and move up a lane if you hit a stop sign such as pain, spreading redness, or hair loss.


Lane 1: Self-care for mild, familiar, or short-lived symptoms

Choose self-care when:
Your scalp is itchy or flaky without pain, fever, patchy hair loss, boggy swelling, or pus. You have had similar flares before that improved with drugstore care. You feel well otherwise.

What to do first, step by step:

  1. Simplify your wash routine. Wash regularly with a fragrance-free, gentle shampoo. If fragrance has bothered your skin before, use products that are truly fragrance-free, not just “unscented.” The Better Scalp Company’s Sensitive Scalp Shampoo and Sensitive Scalp Conditioner are designed for this purpose and are easy starting points for a 2 to 4 week trial.

  2. Use a proven medicated shampoo 2 to 3 times weekly. Rotate one active at a time. Examples include ketoconazole 1 or 2 percent, selenium sulfide 1 percent, or zinc pyrithione 1 percent. Clinical trials show ketoconazole shampoos reduce flakes and itch compared with placebo.⁶ Zinc pyrithione shampoos have also outperformed vehicle shampoos in controlled studies.⁷

  3. Massage, do not scrape. Massage shampoo into the scalp, leave on 3 to 5 minutes, then rinse. Avoid picking or scraping scales, which worsens irritation.

  4. Rinse sweat and product buildup. After workouts or heat exposure, rinse the scalp to limit yeast overgrowth and irritation.

  5. Patch-test new products on a small area behind one ear for 48 hours. If redness or sting develops, stop.

Stop signs during self-care:
Pain, crusting, swollen tender patches, spreading redness, fever, or unexpected hair shedding. These require clinician assessment, often the same day.


Lane 2: Primary care for persistent, uncertain, or generalized symptoms

Choose primary care when:
Self-care fails after 2 to 4 weeks, the diagnosis is unclear, the rash has spread beyond the scalp, or you prefer guided care. Your clinician can examine the scalp, prescribe stronger medicated shampoos or topical anti-inflammatories, and rule out infection.

What primary care can do well:

  • Differentiate dandruff and seborrheic dermatitis from psoriasis or eczema using a focused exam.

  • Prescribe first-line treatments, such as short courses of topical corticosteroids for inflamed plaques, alongside medicated shampoos.

  • Order basic labs or swabs if infection is suspected.

  • Provide referrals when hair loss, scarring, recurrent infections, or diagnostic uncertainty is present.

When primary care should refer you:
Scalp psoriasis impacting quality of life, recurrent or scarring folliculitis, patchy hair loss, suspected tinea capitis, or any case not improving with guideline-based care. Dermatologists are trained to pinpoint the cause of hair loss and complex rashes and to tailor advanced therapies.³


Lane 3: Dermatology for complex diagnoses, hair loss, or scarring risk

Choose a dermatologist when:
You notice sudden or patchy hair loss, thick silvery scales suggestive of psoriasis, boils or painful pustules, scarring, or a boggy, tender swelling. Dermatologists manage these patterns daily, perform scalp exams and microscopy, and can prescribe targeted treatments or perform procedures.

Examples where dermatology helps most:

  • Scalp psoriasis with burning, soreness, or temporary hair shedding from scratching and hard scale removal.⁴

  • Alopecia areata or scarring alopecias that need rapid diagnosis to preserve follicles.

  • Recurrent folliculitis or folliculitis decalvans that risks scarring.

  • Suspected tinea capitis that requires oral antifungals, especially in children or if there are round scaly bald patches.⁵

Urgent care or emergency triggers:
If you develop a rapidly enlarging red, hot, painful area with fever, or streaks of redness, seek urgent evaluation because cellulitis can spread quickly.⁰¹


What are the common scalp conditions and how do they look?


Dandruff and seborrheic dermatitis

Dandruff involves white flakes without much redness. Seborrheic dermatitis brings greasy scale and redness along the scalp, eyebrows, ears, and sides of the nose. Both respond to medicated shampoos. Ketoconazole and selenium sulfide reduce Malassezia yeast, which helps flaking and itch.⁶ Zinc pyrithione also reduces flakes and yeast when enough active is deposited on the scalp.⁷


Scalp psoriasis

Psoriasis is an autoimmune skin condition. On the scalp it forms well-defined, thick plaques with silvery scale that can burn or feel sore and may trigger temporary shedding if you pick at the scale.⁴ Psoriasis often benefits from prescription topicals, light therapy, or systemic medicines when severe. If you suspect psoriasis, book with your clinician, especially if there is joint pain or nail changes.


Contact dermatitis

Contact dermatitis is a reaction to an irritant or an allergen in products like shampoos, dyes, or styling sprays. Fragrance is a common culprit, with fragrance allergy detected in a proportion of both the general public and patch-tested patients.⁸ Choosing truly fragrance-free products and simplifying routines decreases risk. Labels that say “unscented” can still include masking fragrance, which can mislead consumers, so look for “fragrance-free” specifically.⁹ The Better Scalp Company’s Sensitive Scalp Shampoo and Sensitive Scalp Conditioner are fragrance-free and suitable as default options during elimination trials.


Tinea capitis

Tinea capitis is a contagious fungal infection of the scalp. It often starts as a scaly, itchy round patch that can enlarge, and it is more common in children. Testing helps confirm the diagnosis and ensures the right treatment.⁵ Oral antifungals are typically required.


What should I try at home, and how exactly should I do it?

Week-by-week plan for mild flakes and itch

  • Weeks 1 to 2

    • Wash 3 to 5 times weekly based on oiliness.

    • Use The Better Scalp Company Sensitive Scalp Shampoo for routine washes.

    • On two nonconsecutive days, use a medicated shampoo. Choose one active for this trial, such as ketoconazole. Massage into the scalp, leave for 3 to 5 minutes, then rinse.

    • Condition mid-lengths and ends with The Better Scalp Company Sensitive Scalp Conditioner to reduce tangling without coating the scalp.

    • Avoid hair sprays or dry shampoos while troubleshooting.

  • Weeks 3 to 4

    • If flakes persist, switch the medicated active to zinc pyrithione or selenium sulfide for two more weeks.

    • Continue the same leave-on time and gentle technique.

    • If you improved, taper medicated use to once weekly for maintenance.

Tips for comfort

  • Use lukewarm water. Hot water increases itch.

  • Air dry or use a cool setting.

  • Replace old brushes that can scratch the scalp.

  • Record changes in a simple phone note. Patterns help your clinician if you need a visit.

Stop and escalate if there is pain, pus, fever, hair shedding, or if symptoms disrupt sleep or work despite the plan.


What should I bring to a primary care or dermatology visit?

  • A list or photos of products touched by your scalp and hair for the last 8 weeks.

  • Photos of flares in good light.

  • A timeline of any hair shedding, medications, illnesses, or high stress.

  • A list of treatments tried and how often you used them.

  • Known allergies and prior patch test results if available.


What can a dermatologist add beyond primary care?

Dermatologists perform trichoscopy, bedside microscopy for scale or hair, fungal cultures, and when needed, small punch biopsies to confirm diagnoses that put follicles at risk. They also tailor topical anti-inflammatories to your hair type and schedule, and can escalate to oral antifungals for tinea capitis, targeted antibiotics for specific folliculitides, or advanced therapies for psoriasis.


How do I prevent future flares?

  • Keep a steady rhythm. Frequent small adjustments beat big swings.

  • Stay with a simple, fragrance-free base routine. Consider The Better Scalp Company Sensitive Scalp Shampoo and Sensitive Scalp Conditioner as your default.

  • Rotate a medicated shampoo once weekly during seasons when you usually flare.

  • Rinse after sweat or heavy styling.

  • Re-introduce new products one at a time with patch-testing behind the ear.


Quick-look table: self-care vs primary care vs dermatologist

Scenario Self-care you can start today See primary care when See a dermatologist when
Mild flakes without redness Fragrance-free base wash such as The Better Scalp Company Sensitive Scalp Shampoo. Add ketoconazole or zinc pyrithione shampoo 2 to 3 times weekly. Leave on 3 to 5 minutes No change after 2 to 4 weeks or diagnosis is unclear Recurrent flares despite correct use or severe scaling across scalp and hairline
Itchy, red, greasy scale around scalp and eyebrows Same as above, consider selenium sulfide rotation Rash extends to face, beard, chest, or ears despite self-care You need prescription anti-inflammatories or have frequent relapses
Thick plaques with silvery scale and soreness Gentle fragrance-free products only. Avoid scraping Plaques spread or itch disrupts sleep Suspected scalp psoriasis needing targeted therapy or if hair sheds from picking⁴
Round scaly bald patch, especially in a child Do not delay. Avoid sharing combs or hats Same day for evaluation and testing Confirmed tinea capitis needing oral antifungal therapy⁵
Tender red lump with pustules or crust Warm water cleansing only. Avoid squeezing If not better in 24 to 48 hours or if painful Repeated or scarring folliculitis, or if boils recur
Rapidly spreading redness, heat, pain, fever Do not self-treat Same-day in-person evaluation Urgent care or emergency care for suspected cellulitis⁰¹

Gentle myth-busting

  • “Unscented” equals safe for sensitive scalps. Not always. Some “unscented” products include masking fragrance. Look for “fragrance-free” instead.⁹

  • Flakes always mean dry scalp. Many people with flakes have seborrheic dermatitis or dandruff that respond to antifungal actives.⁶

  • Scraping scale makes medicated shampoo work faster. Scraping worsens inflammation and can increase hair shedding in psoriasis.⁴


Encouragement and next steps

Sensitive scalps are common and treatable. Start with a simple fragrance-free base, add one medicated shampoo, and give it two weeks. If you do not improve, bring your notes and products to your clinician. Early, targeted care prevents unnecessary hair shedding and gets you back to comfort.
