en Frontal fibrosing alopecia: catching the receding hairline before it settles
Summary
The forehead clears slowly, in an even band, and the hairline creeps back by a centimetre. Then by two. In many women, though, the first change happens somewhere else entirely: the eyebrows start thinning, sometimes months before the hairline shifts at all. Frontal fibrosing alopecia advances quietly, and that is exactly what makes it so hard to catch early.
It belongs to the family of scarring alopecias, a category of its own among the different forms of hair loss. What that means is harsh, but simple: over the affected area, the loss is permanent. Nothing brings back what has gone. The goal of treatment therefore shifts elsewhere, towards stopping the disease from spreading further.
Inflammation that destroys the hair follicle
First described in 1994, frontal fibrosing alopecia is now regarded as a particular form of lichen planopilaris, an inflammatory disease of the scalp in which the immune defences turn against the hair follicle, the small pocket of skin that manufactures the hair.
The inflammation concentrates on the upper part of the follicle. It damages it, then replaces it with fibrous tissue, a kind of scar. The result is visible to the naked eye: the skin of the forehead turns smooth, slightly shiny, often paler, and the tiny openings the hairs used to emerge from have gone. That detail matters. As long as the openings can still be seen, the follicle is still there.
Why regrowth never comes back on the affected area
Hair lives in cycles. It grows for several years, stops for a few weeks, falls out, and a new shaft sets off from the same follicle. The mechanism loops round for a lifetime.
In frontal fibrosing alopecia, the part of the follicle that houses the stem cells is destroyed. The cycle never restarts. That is the whole difference with androgenetic alopecia, where the follicle weakens and shrinks but stays alive, which is what gives medical treatments for hair loss something to work on. Here, there is nothing left to wake up.
Recession in a band, what sets it apart from ordinary baldness
Male pattern baldness hollows out a temple on each side of the forehead and leaves a central peak. Frontal fibrosing alopecia does the exact opposite: it recedes in an even, symmetrical band across the full width, as though the hairline had been pushed back in one piece. The forehead looks higher and broader, and the recession often carries on above the ears, sometimes as far as the temples.
Two signs usually travel with that recession. Small rough bumps around the hairs still standing, right at the edge of the affected zone. And itching or a burning sensation, faint but persistent, which patients sometimes take months to connect with their hair loss. A single hair left stranded in front of the new hairline is typical too.
The eyebrows: the most useful clue for catching it early
This is the point worth remembering. In a large share of patients, the eyebrows start thinning before the forehead changes at all, beginning with the outer part. They grow sparse, then sometimes disappear altogether.
An eyebrow thinning for no obvious reason after the age of 45 deserves a dermatology opinion. Not in six months’ time: now. That is the window in which treatment can still preserve an intact hairline. An eyebrow transplant can be discussed later, once the disease has quietened down, but it does nothing about the scalp itself.
Other hair-bearing areas can be involved: eyelashes, facial vellus hair, underarms.
Redness and small bumps on the face
Rosacea, a chronic skin condition that causes redness across the cheeks and nose, is seen more often than average in these patients. Small flesh-coloured papules on the temples are also described, easily mistaken for an ordinary skin blemish.
These signs do not make the diagnosis on their own. They point towards it.
Who is affected, and why case numbers keep rising
Women past the menopause make up the vast majority of cases, most often after the age of 50. A link with hormones is strongly suspected without being proven. A European study of 490 patients confirmed that female, post-menopausal dominance.
That rules nobody out. Younger women are affected, and so are men, more rarely. In men, sideburn and beard involvement frequently accompanies the frontal recession.
The most striking feature remains the marked increase in the number of cases over the past thirty years, in every country where it is tracked. Better recognition of the disease explains part of that rise. The rest is debated, and no single cause has been established. In practice it changes one thing above all: faced with hair loss in a woman, the diagnosis now has to be considered.
Diagnosis is made with a dermatoscope, sometimes with a biopsy
The dermatoscope is a small illuminated magnifier placed against the scalp. It enlarges the skin and shows three decisive things: the loss of the follicular openings, scaling that forms a collar around the hairs still present, and faint redness at their base. That trio is the one retained by a multicentre study from the International Dermoscopy Society (Starace et al., 2022). A first-line examination, painless, carried out in consultation.
When the picture stays ambiguous, the dermatologist takes a scalp sample a few millimetres across under local anaesthetic. Analysis under the microscope settles the matter: it reveals the characteristic inflammatory infiltrate and the fibrosis. This step also rules out the other causes of frontal recession, notably traction alopecia, caused by tight hairstyles, whose appearance can be misleading, or a hormonally driven postmenopausal alopecia.
Slowing the progression, the realistic goal
No treatment cures frontal fibrosing alopecia and none regrows the hair already lost. What is being sought is a brake on the inflammation, to protect the follicles still alive behind the line.
The 5-alpha-reductase inhibitors, finasteride among them, are among the most widely used in this indication and produce the best stabilisation rates reported. Depending on the case, dermatologists combine them with topical corticosteroids, a synthetic antimalarial such as hydroxychloroquine, or other immunomodulators. JAK inhibitors, a more recent arrival, are the subject of ongoing work. All of this falls strictly under prescription and follow-up.
One piece of good news in the middle of all that: the disease often ends up burning out on its own after several years. It does not go into reverse, but it stops advancing.
Hair transplant: possible after stabilisation, without overpromising
This is the question nearly every patient asks. Yes, a transplant can redraw a hairline over an area destroyed by frontal fibrosing alopecia. No, it is not a procedure like any other.
The first condition is not up for negotiation: the disease must have been stable for at least two years, with no fresh recession, no redness, no itching. Grafting onto a scalp that is still inflamed means implanting grafts into an area that will destroy them. Any serious suitability assessment starts there.
The second condition concerns the skin itself. A fibrotic scalp is stiffer and less well supplied with blood than a healthy one, and graft survival there is less predictable.
It is worth going further than that general caution, because the literature is specific. A 2025 review brought together 33 studies covering 147 patients grafted for a scarring alopecia. The overall result is fairly good, but it hides considerable variation between diseases: lichen planopilaris does very well, whereas frontal fibrosing alopecia of the scalp sits among the subtypes with the poorest outcomes (Queen & Avram, 2025). That same review sets the recommended stability threshold at twelve to twenty-four months. We hold to the upper limit, and you now know why.
It raises one last point, this time about diagnosis: 46 patients in the series had developed a scarring alopecia after being grafted for what had been taken for ordinary baldness. That is the strongest argument there is for a thorough examination before any procedure, including when the picture looks unremarkable.
In that context, some teams begin with a test graft over a small area, then wait a year before going any further.
Harvesting is done from the crown at the back of the head, following the usual methods. The donor area still has to be unaffected, which is not always the case since the disease can, more rarely, reach it too. In women, the procedure is most often performed without full shaving, which makes getting back to normal life easier: a hair transplant for women follows its own rules.
A consultation for a hair transplant Turkey allows the affected area to be examined, the length of the stabilisation to be checked, and a clear answer to be given on what is reasonable to consider. Including, at times, advice to wait a while longer.
