Hair loss: Medical guides
Hair loss has identifiable causes and treatments with proven efficacy — and time matters: the sooner it is assessed, the more follicle there is to preserve. These guides explain how to tell androgenetic alopecia from alopecia areata, which drugs are approved and what to expect from each.
Treatments and medicines
Female androgenetic alopecia: which treatments have evidence behind them and which is approved in Spain
In Spain, the only treatment approved specifically for female androgenetic alopecia is topical minoxidil 2%, and a Cochrane review backs it up. We explain what the trials show, what is known about the alternatives used off-label, and what a doctor looks at before suggesting treatment.

Androgenetic alopecia in women: why it is different and what options exist in Spain
Female pattern hair loss is not a milder version of male baldness: it looks different, it is rarely explained by hormones alone and other causes have to be ruled out first. We go through what the evidence says about each treatment and where each one really stands in Spain.

How long does hair loss treatment take to work: a month-by-month timeline and the initial shedding
In androgenetic alopecia, the changes brought about by hair loss treatment are usually measured in months, not weeks. This is the most realistic timeline for understanding when a temporary initial increase in shedding may appear, when stabilisation can usually be expected and over what timescales results become visible.

Oral vs topical minoxidil: what the head-to-head trials say
For years the comparison between oral and topical minoxidil was based on impressions. Since 2024 there has been a randomised trial and a meta-analysis that pit them directly against each other: the conclusion is similar efficacy, with a slight edge for the oral form at the vertex and one side effect that is clearly more frequent when taken by mouth. We explain what is known, what is not and why the difference matters.

Low-dose oral minoxidil: a map of the real side effects
Oral minoxidil has become one of the most talked-about treatments for hair loss, but in Spain it remains a drug authorised only for severe high blood pressure. Here is what the data say about its side effects: which ones appear, how often, and what is known about the rare but serious ones.

Baricitinib and JAK inhibitors: the new treatment for alopecia areata
Baricitinib (Olumiant) is the first systemic drug authorised in Spain for severe alopecia areata: in adults and in adolescents aged 12 and over, and publicly funded in adults. Here is what it is, what the trials found and where the caveats lie.

Finasteride for hair loss: how it works, results and side effects
Finasteride is one of the treatments authorised in Spain for androgenetic alopecia in men. We explain how it acts on DHT, what the trials show, which side effects the EMA has been monitoring since 2025 and why the decision is always an individual medical assessment.

Types and causes
Hair loss after rapid weight loss or bariatric surgery: why it starts months later
If your hair starts falling out months after losing weight quickly or having surgery, the most likely cause is telogen effluvium. This is diffuse, non-scarring hair loss that shows up late because of the way the hair follicle cycle works. We explain why it happens, which nutrients matter most and what the evidence says.

Androgenetic alopecia in women: why it's different and what options exist in Spain
Female pattern hair loss rarely leaves bald patches; instead it widens the parting and thins the hair gradually. What the evidence says, how it is classified and what is authorised in Spain for women, with the figures from Cochrane and from the AEMPS product information.

Telogen effluvium: the sudden hair loss that frightens and usually reverses
You notice more hair than usual on the pillow or in the shower and it gives you a fright. Telogen effluvium is the most common cause of diffuse hair loss: it appears after physical stress, childbirth or a hormonal change, and in most cases it resolves on its own. Here is why it happens, what the evidence says and what is actually known.

Alopecia areata: what it is and how it differs from common hair loss
Alopecia areata is not the same as ordinary balding. We explain what defines it, why it happens, how it is diagnosed and how it differs from androgenetic alopecia, based on the evidence available today.

Androgenetic alopecia: why hair falls out and how far it goes
Androgenetic alopecia is the most common cause of hair loss and comes down to a mix of hormones and genetics. Here's what happens inside the follicle, how it progresses and which myths are worth leaving behind.

Guides, prices and comparisons
Minoxidil prices in Spain: why topical and oral cost so differently
In Spain there are four brands of topical minoxidil 5%, an official preparation from the Spanish National Formulary, compounded formulations and an oral presentation. Here is what is authorised, what makes one pack cost more than another, and why you will not read a figure in euros here that we cannot verify.

Hair clinic or telemedicine: what changes in diagnosis, follow-up and price
For typical androgenetic alopecia, remote hair consultations get the diagnosis right in the vast majority of cases. Types of hair loss that need trichoscopy still call for an in-person appointment. We look at what the studies say about diagnosis, why follow-up timelines are the same in both settings and what can honestly be said about price.

Finasteride price in Spain: the real monthly cost, branded and generic
In Spain, finasteride 1 mg for hair loss is prescription-only, and you should not assume it is funded by the National Health System. There is no verified official retail price (PVP) in the facts available, so the real cost is easier to understand by pack size and how long each pack lasts. At 1 mg a day, a 28-tablet pack lasts just under a month and a 98-tablet pack lasts just over three months.

Diagnosis and tests
Frontal fibrosing alopecia: warning signs, diagnosis and which treatments are considered
Frontal fibrosing alopecia is a primary scarring alopecia that usually shows up as a band-like recession of the frontal or frontotemporal hairline, often with loss of the eyebrows. Spotting it early matters because the realistic aim of treatment is to calm the inflammation and stabilise the loss, not to promise that the hair will fully come back.

Nutraceuticals and supplements
Hair supplements (biotin, saw palmetto…): what works and what does not
Biotin, hair complexes, plant extracts: every month a new bottle appears promising to stop hair loss. We look at what the evidence really says, what effect nutraceuticals have and why biotin can give you a scare on a blood test.
