How to use this knowledge guide
Use this page as a map. The six guides above are in the order most people need them: the first helps you understand why your hair is falling out, the second covers what you can do without surgery, and the third explains the operation itself. After that come how to choose a clinic, what happens afterwards and how long the result lasts. Read them in order, or go straight to the one that matches where you are now.
The sections below introduce all six in a few paragraphs, so you can see where your own case fits. If the subject is new to you, start here.
First step: understand your type of hair loss
Everything begins with the diagnosis. Hair loss is a symptom, not a single disease, and the right treatment depends on the cause. Most permanent hair loss is androgenetic (hereditary) alopecia, in which the hormone DHT gradually miniaturises genetically sensitive follicles. A large share, though, comes from temporary or treatable conditions: telogen effluvium (diffuse shedding after stress, childbirth or illness), deficiencies or thyroid disorders.
The difference matters, because surgery only helps with permanent, patterned loss, not with temporary or autoimmune hair loss. The guide to the causes of hair loss goes through the growth cycle, the Norwood and Ludwig scales and each cause in turn.
Treatment: from medication to surgery
For hereditary hair loss, medical treatment is often the first step, and a precondition for a durable surgical result. Finasteride lowers DHT and Minoxidil stimulates growth; PRP and microneedling can add some support on top. The guide to slowing hair loss without surgery covers each option in detail.
If the loss is advanced, a hair transplant can rebuild areas where the follicles have been lost. The four methods (FUE, DHI, FUT and Sapphire) differ in how the grafts are harvested and implanted. The guide to hair transplant methods explains those differences, which makes it easier to see through clinic marketing.
Choosing a clinic, recovery and the long term
No decision matters more for the result than the choice of clinic and surgeon. Our guide to choosing a clinic has a checklist, the red flags to watch for and the questions to ask at a consultation, plus what to check before you travel abroad for treatment.
If you go ahead, the recovery is part of the treatment. The first days are critical for the grafts, and you will not see the final result until 12-18 months after surgery. The aftercare guide covers what to do and when. For how the result holds up over decades, and why many patients stay on medication to protect their original hair, see the guide to longevity.
A glossary of the most important terms
| Term | Meaning |
|---|
| Androgenetic alopecia | Hereditary hair loss driven by the hormone DHT; the most common cause of permanent loss. |
| DHT (dihydrotestosterone) | The hormone that miniaturises genetically sensitive follicles. |
| Miniaturisation | The gradual process in which hairs become thinner and shorter with every growth cycle. |
| Graft | A transplanted follicular unit, a natural group of 1-4 hairs. |
| Donor area | The back and sides of the head, where the follicles are largely resistant to DHT and can be moved. |
| Donor dominance | The principle that relocated hair keeps its original properties in its new position. |
| Shock loss | Temporary loss of transplanted (and sometimes original) hair after the operation. |
| Telogen effluvium | Diffuse, usually temporary hair loss triggered by stress, illness or deficiencies. |
Getting started
The advice is the same at every stage: understand your situation before you choose a treatment. Read the guides that apply to you, write down your questions and take them to a doctor who treats hair loss. Your donor supply is limited and the first operation is your best chance at a good result, so it is worth taking a few weeks to read up before you book.
