Hair clinic or telemedicine: what changes in diagnosis, follow-up and price

Hair telemedicine works well for the most common case, typical androgenetic alopecia. In a 2025 study of 321 cases of non-scarring alopecia, 91.3% were diagnosed remotely, with no clinic visit needed. You still need to go to a clinic when the diagnosis depends on examining the scalp with trichoscopy, as in alopecia areata, trichotillomania or frontal fibrosing alopecia. There are no reliable data comparing prices in Spain, so the useful thing is to know which items make up the cost.

Choosing between the two isn't about one being modern and the other traditional. What matters is the type of hair loss you have, what it takes to put a name to it, and how it will be monitored over the months any treatment takes to show results.

What an in-person consultation offers: trichoscopy

The main tool of an in-person consultation is trichoscopy, which is dermoscopy of the scalp. It is a non-invasive examination done in the clinic with a handheld or digital dermatoscope. It shows details you can't see with the naked eye or in an ordinary photo: the thickness of each hair, what the follicle openings look like, and whether there is inflammation around them.

A review published in Actas Dermo-Sifiliográficas, the journal of the Spanish Academy of Dermatology and Venereology (AEDV), says trichoscopy is key to diagnosing and monitoring alopecia areata, trichotillomania and frontal fibrosing alopecia. Looked at only from a distance, all three can be mistaken for one another or for ordinary hair loss, and each is managed very differently. If you'd like to know how the first of these differs from hereditary hair loss, we explain it in alopecia areata: what it is and how it differs from ordinary hair loss.

What telemedicine diagnoses well, and what it doesn't

The evidence on teledermatology for alopecia is stronger than many people think. It has one clear limit, though: almost all of it comes from patients with androgenetic alopecia.

• A 2025 retrospective study looked at 321 cases of non-scarring alopecia handled through asynchronous teledermatology, meaning the specialist reviewed photos and a questionnaire afterwards. A definitive diagnosis was made remotely in 91.3% of cases, and only 8.7% needed an in-person consultation.
• A systematic review of 9,622 patients found that 93.5% had androgenetic alopecia and only 1.1% had alopecia areata. In the studies that measured it, remote diagnostic accuracy was 100%, and 52% of patients followed up by telemedicine had hair regrowth or improvement.
• The counterpoint comes from a paediatric study using photos taken by parents. Agreement between remote and in-person diagnosis was 64% for alopecia, compared with 100% for birthmarks and 92% for rashes. Alopecia was the category with the most remote errors.

Read honestly, these data show that telemedicine performs very well when the picture is typical: gradual thinning at the temples or crown, with a family history. Accuracy of 100% in studies where almost everyone had that diagnosis doesn't prove it works equally well for every type of alopecia. With less common forms, in children, or with poor-quality photos, the margin of error grows.

When it makes sense to be seen in person

A good remote service also knows when to refer you on. If you're asked to come in for an in-person consultation, you're part of that 8.7% from the 2025 study, and that's a good sign. It usually happens in these situations:

• Round, clearly defined bald patches that appear suddenly, typical of alopecia areata.
• A receding front hairline with smooth or shiny skin, loss of eyebrows, or itching or redness around the follicles. These signs mean a scarring alopecia such as frontal fibrosing alopecia must be ruled out. We cover this in frontal fibrosing alopecia: warning signs and diagnosis.
• Hairs broken off at different lengths, which can point to trichotillomania.
• Hair loss in children.
• A picture that doesn't fit the typical pattern or doesn't progress as expected.

Follow-up: the timelines are the same in both settings

No format speeds up the biology of the hair follicle. Take finasteride, the medicine authorised in Spain for male androgenetic alopecia. Its summary of product characteristics (SmPC) from the AEMPS, the Spanish medicines agency, indicates it for men aged 18 to 41 with early-stage androgenetic alopecia, to stabilise hair loss. It has not been shown to work for bitemporal recession (what we call receding temples) or for advanced baldness.

The same SmPC sets out the timelines. It takes 3 to 6 months to see the first signs of stabilisation, and treatment must be taken continuously. If it is stopped, the benefit starts to fade after 6 months, and by 9-12 months things are back to where they started. That is why good follow-up depends on continuity, not on where it takes place. We go into more detail in how long hair loss treatment takes to show results, month by month.

Keep this in mind when reading one telemedicine finding. A 2023 study followed 2,269 patients on a German finasteride platform. Six weeks after their first prescription, 79% said they had noticed positive changes in their hair, 12% had had side effects and 87% said they were taking the treatment as prescribed. These were questionnaire answers. Since the official timeline is 3 to 6 months, such an early impression says more about adherence and expectations than about how well the drug actually works.

Following a patient up also means monitoring their safety. In 2025, the PRAC, the pharmacovigilance committee of the European Medicines Agency (EMA), confirmed the risk of suicidal ideation with finasteride. It identified 325 relevant cases, 313 with finasteride and 13 with dutasteride, and 83% of the finasteride cases were in people treated for androgenetic alopecia. Packs of the 1 mg tablets now come with a patient information card about the risk of depression, sexual dysfunction and suicidal ideation. Whether follow-up is in person or remote, it should actively ask about mood and sexual function, not just hair.

Oral minoxidil: a prescription is essential either way

Oral minoxidil is used off-label for alopecia. It is not authorised in Spain for this indication, although dermatologists use it widely. According to Actas Dermo-Sifiliográficas, in Spain some doses are obtained by splitting Loniten® tablets, and the lowest doses usually need a compounded (extemporaneous) preparation made up on a doctor's prescription. In a clinic or remotely, this use needs a doctor to assess the case, decide whether it is suitable and monitor how well it is tolerated.

And the price: what can honestly be said?

There are no reliable data comparing prices between in-person hair clinics and telemedicine platforms in Spain, so we won't give you figures. Nor can anyone say that one option is always cheaper. What you can do is compare like with like, item by item:

• The first assessment: whether it includes a trichoscopy examination or is based on photos and a questionnaire.
• Any additional tests, if they are requested.
• The medicine, which you pay for separately at the pharmacy. You can see what affects that cost in finasteride: the real monthly cost, branded and generic.
• Review appointments: how many the service includes, how often they happen and whether you pay for them separately.
• Travel and time, which don't appear on the bill but still count.

Any effective treatment is kept up for years, so the cost that matters is the cost of ongoing follow-up, not of the first visit.

In short: which format suits your hair loss

For typical androgenetic alopecia, there is good evidence that telemedicine diagnoses it well. For atypical or scarring cases, or in children, in-person trichoscopy is still needed. Either way, what makes the difference is continuous follow-up that is honest about timelines. In Spain you can already get medical treatment for hair loss with an assessment first, a prescription from a registered doctor where appropriate, and ongoing follow-up. That is what AiON offers, and if your case needs an in-person consultation, we will tell you. You can check in a few minutes whether the treatment is right for you.
