Scalp work in Delhi is shaped by a specific environmental cocktail. Particulate pollution settles on the scalp through the day; air-conditioning and indoor heating cycles dehydrate the surface; chlorinated water in many residential supplies disrupts the lipid film; the cultural pattern of weekend hot-oil application combined with daily shampoo creates an oscillation that the scalp barrier rarely fully recovers from. The clinical picture for many adult Delhi patients is therefore not "one diagnosis" but a layered presentation — a base of mild seborrhoeic activity, episodic flares around pollution peaks, mid-month dryness from over-shampooing, and an occasional acute irritation event triggered by a new product. The DDC framework is to map the layers at the first visit and treat the highest-leverage layer first rather than running a generic anti-dandruff routine across all of them.

Trichoscopy of the scalp is the under-used diagnostic step that frequently changes the plan. Plain visual inspection picks up obvious flakiness and visible erythema, but the dermoscopic view reveals follicular plugging patterns, perifollicular inflammation, broken hair shafts, scaling distribution, and small-vessel telangiectasia that together differentiate the seborrhoeic-pattern scalp from the irritant-contact pattern from the early scarring-alopecia presentation. Two patients can present with similarly itchy, flaky scalps and walk out with significantly different plans because the trichoscopic pattern has identified that one is on the seborrhoeic spectrum and the other on the contact-irritation spectrum, with different management. The procedure adds minutes to the consultation and frequently saves weeks of mis-treatment.

The dryness-versus-greasiness diagnostic question is one of the most commonly mistaken self-assessments. Patients who notice flakiness often assume the scalp is dry and respond by oiling more aggressively; in seborrhoeic patterns, however, the underlying biology is increased sebaceous activity with Malassezia overgrowth, and additional oil worsens the picture rather than helping. Conversely, patients with genuine xerotic scalp who reach for daily anti-dandruff shampoo find the scalp becoming more reactive over weeks because the surfactants are stripping a barrier that is already compromised. The first-visit assessment at DDC therefore explicitly asks about the patient's current routine and works backwards from the observed pattern; "do less of what you are currently doing and add this specific product" is a common conversation.

Scalp psoriasis sits in its own category and warrants direct mention. The presentation is well-defined plaques with thicker, silvery scaling, often on the hairline and behind the ears, sometimes with extension to the body. The biology is autoimmune rather than seborrhoeic; the management framework includes topical corticosteroid pulses, vitamin-D-analogue topicals, salicylic-acid keratolysis to soften plaques, and in moderate-to-severe cases a referral conversation about systemic options that sit outside the routine scalp visit. Mistaking scalp psoriasis for stubborn dandruff is one of the more common reasons "dandruff treatment isn't working" — the antifungal shampoo is not the wrong tool, it is simply the wrong category.

Folliculitis on the scalp is yet another category that needs its own routing. The presentation is small inflamed bumps around hair follicles, sometimes with mild tenderness, sometimes with pustules. Bacterial folliculitis responds to antibacterial shampoo and short courses of antibiotics where indicated; fungal folliculitis (commonly Malassezia-related) responds to antifungal-active care; eosinophilic folliculitis and acne-keloidalis-nuchae sit in their own treatment frames. The first visit differentiates these patterns and writes the plan accordingly; treating bacterial folliculitis as if it were dandruff is one of the cleaner ways for a scalp picture to drag for months.

Finally, the long-term framing for chronic scalp patterns is worth setting at consultation. Many of these presentations — seborrhoeic dermatitis in particular — are chronic-relapsing rather than curable. The realistic objective is sustained control with a maintenance protocol that the patient can run independently, episode-detection skill so that flares are caught early, and a clear pathway back to the clinic when the maintenance plan is being outpaced by the biology. Patients who arrive expecting a single course that ends the condition leave the consultation with a different and more useful mental model: management, control, and a plan that travels with them.
