Brief Answer:
I suggest you to use a ketoconazole based shampoo alternate days

Detailed Answer:
Hello and welcome to healthcaremagic

I have gone through your query and I have understood it.

Dandruff or seborrheic dermatitis is an important cause of scalp itching and increased hair shedding.
Therefore treating dandruff adequately would reduce itching as well as hair fall.

In my patients I usually suggest a ketoconazole based antidandruff shampoo, every alternate days Or even daily.
Ketoconazole is antiseborrheic and antifungal, therefore, is of benefit in mild to moderate seborrheic dermatitis.
Nizoral is a ketoconazole based shampoo and is available OTC. It is marketed by XXXXXXX & XXXXXXX
Lather it well on your scalp and allow it to act for 5-7 minutes before rinsing it off.

In some cases, dandruff is stubborn and an antidandruff shampoo alone seems insufficient in providing complete relief.

In such stubborn cases I usually ask my patients to use a topical potent steroid lotion (e.g either mometasone furoate 0.1% lotion Or clobetasol propionate 0.05% lotion with or withour salicylic acid), twice daily at the scalp skin.

Seborrheic dermatitis is a steroid responsive dermatoses and therefore topical steroids bring about rapid improvement, usually within days.

Topical steroid lotions are prescription products.

With topical steroids remarkable improvement is usually achieved, within 2 -4 weeks. Thereafter they can be discontinued.

Since dandruff is bound to recur, therefore, rather than using a regular shampoo, patients who have dandruff may use a ketoconazole antidandruff shampoo to keep dandruff under check.

You may try an OTC Ketoconazole based shampoo, and use it every alternate days.
It that seems insufficient you may visit a dermatologist in your region for further interventions e.g prescription topical steroids.
Resistant dandruff can also be due to other conditions like scalp psoriasis and that can only be confirmed by a visual inspection.

Hope this information helps

Brief Answer:
I suggest a possibility of cholinergic Urticara

Detailed Answer:
Hi.

I will suggest a possibility of cholinergic urticaria/ hives i.e urticaria appearing in response to changes in core body temperature.
Various stimuli that might trigger an episode of cholinergic urticaria are sudden changes in ambient temperature, strong emotions, exercising, spicy food, hot shower etc.
These stimuli induces release of histamine from circulating mast cells manifesting as hives.
It is a type of chronic urticaria and treatment is symptomatic i.e once daily Oral antihistamine e.g cetrizine 10 mg once daily apart from avoidance of triggering factors.
Topically you may use a soothing lotion e.g calamine.
