The diagnosis comes first here. Clinical examination, dermoscopy or trichoscopy where it's needed, and the tests that are actually indicated — then a treatment plan explained to you in plain language.

What's bothering you?
Start with the problem, not the procedure. Each page covers what it is, what it's commonly mistaken for, and how it's diagnosed.
My hair is falling out
Thinning at the crown or hairline, sudden shedding, bald patches, dandruff that keeps returning.
Pimples that keep coming back
Acne at any age, painful bumps under the skin, and the marks and pits left behind.
Dark patches on my face
Melasma, dark circles, uneven tone, and darkening left behind after a rash or acne.
Patches that won't go away
Scaly plaques, white spots, dry cracking skin — psoriasis, vitiligo and eczema.
It itches and I can't stop scratching
Ringworm and other fungal infections, hives, and skin damaged by steroid creams.
Something I'd rather not discuss
Genital and intimate skin problems, examined and treated matter-of-factly.
How a diagnosis is made
Treatment is only as good as the diagnosis behind it. This is what happens before anything is prescribed — in clinic, and as far as it can be done over video.
- 1
History, taken properly
How long, what changed before it started, what has already been used on it — including creams bought without prescription. Steroid misuse is common and changes the whole picture.
- 2
Clinical examination
The pattern, distribution and surface of a lesion carry most of the answer. Nails, scalp and mucosa are examined too, because several conditions declare themselves there first.
- 3
Dermoscopy and trichoscopy
Magnified examination of skin and scalp. It separates conditions that look identical to the naked eye — and it is how hair loss should be assessed before any treatment is started.
- 4
Tests, only where indicated
Thyroid, ferritin, vitamin D or hormonal profile when the history points there — not a routine panel for everyone. You will be told what each test is looking for.
- 5
KOH mount for suspected fungal infection
A simple bedside test that confirms or rules out fungus in minutes. Skipping it is why so many rashes are treated for months with the wrong cream.
- 6
Biopsy where the diagnosis isn't clear
A small sample under local anaesthetic, read by a pathologist. Uncommon, but the right step when the appearance is atypical or a condition has not responded as expected.
A wrong diagnosis costs months
Anti-fungals for a rash that isn't fungal. Supplements for hair loss that is hormonal. Steroid creams that suppress a problem while making it worse. Each delays the treatment that would have worked. Getting the diagnosis right first is the shortest route to clear skin and healthy hair.
Already been treated two or three times without improvement?
That is most of the practice. Bring your prescriptions, the names of what you have used, and any reports. The first job is to establish what the condition actually is — which sometimes means the earlier diagnosis was right and the treatment simply needed longer.
Bring with you
- — Every cream, tablet or oil you are using, including ones bought without a prescription
- — Previous prescriptions and blood reports
- — Photographs of the problem at its worst
- — Roughly when it started and what has changed since
What can be controlled, and what cannot be cured
Some conditions settle completely. Others can be kept quiet for years but return if treatment stops. You will be told which of the two you have at the first consultation, before any money is spent on a plan.
Usually clears fully
Fungal infections, bacterial infections, scabies, molluscum, most drug and contact reactions.
Can be brought under control
Acne, melasma — treatable to a clear state, with maintenance to hold it there.
Managed long term, not cured
Pattern hair loss, psoriasis, eczema, vitiligo. Anyone promising a permanent cure for these is selling something.
Consult online, from anywhere in India
A video consultation with the same approach as the clinic. Conducted under India's Telemedicine Practice Guidelines — identity verification and recorded consent are part of the booking.

Book a slot
Pick a time, confirm your identity and consent, and pay the fee. You get a confirmation on WhatsApp.
Step 2
Send photographs
Clear photos of the affected area in daylight, plus any reports and the names of creams or tablets already used.
Step 3
The consultation
15–20 minutes on video. History, examination of what can be seen, the likely diagnosis, and what it is not.
Step 4
Plan and prescription
A written plan and a digital prescription for what the telemedicine rules permit, with a review date.

About Dr Hitesh Aggarwal
A dermatologist since 2017 and a doctor since 2012. He sees patients at two clinics in Delhi — Narela in the morning, Rohini in the evening — and online for patients elsewhere in India.
His work is mostly medical dermatology rather than cosmetic: hair loss, acne and acne scarring, pigmentation, psoriasis and eczema, and fungal infections that keep coming back. A large share of it is second opinions — conditions already treated once or twice without a clear diagnosis.
He also teaches, running facial aesthetics workshops for practising doctors.
What patients say
A few of the 655 Google reviews across the Narela and Rohini clinics.
655 Google reviews
Two years of anti-fungal creams from different doctors. He did a test the same day and told me it was not fungal at all. It cleared in six weeks.
He examined my scalp under a device and showed me what he was seeing, then explained why the supplements I was taking would not help.
I had been to a big hospital before this. This was the first time someone explained what the condition was and how long it would take.
Reviews describe individual experiences. Outcomes differ between patients, and no result is guaranteed.
