Alopecia treatment: what works, depending on the type of hair loss

Summary

There is no such thing as one alopecia treatment. There are several, and the right one depends entirely on what is making the hair fall out. Inherited balding that has crept along for ten years and a round bare patch that appeared in three weeks share no mechanism whatsoever. The word alopecia actually covers a set of very different conditions, which is the first reason so many people wear themselves out with products that never stood a chance of working on their particular case.

Here are the main patterns of hair loss, and for each one what has genuinely been shown to help.

Getting the diagnosis right before treating anything

A treatment that works beautifully on one form of alopecia can be entirely useless on another. So the starting point is never a product. It is an examination.

The doctor looks at how the loss is distributed, at the density around the temples and over the crown, at the state of the skin between the hairs. A dermatoscope is often used as well, a lit magnifier that enlarges the scalp and shows the condition of the follicular openings. That examination answers the question everything else hangs on: is the follicle still alive, or has it been replaced by fibrous tissue?

A living follicle can be coaxed back into action. A destroyed one cannot. No known molecule regrows hair where the follicular unit has gone. The line is a sharp one, and it explains why the rest of this article is organised around patterns of loss rather than around products.

Blood tests are added where relevant, occasionally a small scalp biopsy. Understanding the hair cycle also helps make sense of what is being seen: a hair grows for years, then rests, then sheds. Shedding may therefore reflect nothing more than a disturbed cycle, which is reversible, or gradual miniaturisation, which is far less so.

Androgenetic alopecia: two molecules, and that is the list

Androgenetic alopecia is by a distance the most common pattern. It comes from an inherited sensitivity of the follicles to DHT, a by-product of testosterone. Under its influence each cycle produces a slightly finer, slightly shorter hair, until nothing comes through at all. The temples recede, the crown thins, the horseshoe of hair around the back and sides stays put. The Norwood scale, a seven-stage chart of male pattern balding, is used to place that retreat.

Only two medicines rest on solid scientific evidence, and European guidelines put both of them in the front line.

Minoxidil goes onto the scalp, as a solution or a foam, twice a day. It lengthens the growth phase of the hair and improves the local blood supply. It is sold in two strengths: 2%, used by men and women alike, and 5%, licensed for men. Nobody should expect a quick verdict from it. Allow four to six months before judging anything, and expect a passing burst of shedding in the first few weeks, which throws a lot of patients and makes them give up when they should not.

Finasteride is taken by mouth, on prescription. It blocks the enzyme that converts testosterone into DHT and so lowers DHT levels at the scalp. Its ability to slow hair loss is well-documented in the literature. But it calls for genuine medical follow-up. A minority of men report sexual side effects, and that alone is reason enough to discuss the drug with a prescriber rather than order it from a website. In women who could become pregnant it is contraindicated, because of the risk to a male foetus. The mood-related side effects have also been taken seriously by regulators: British packs of finasteride have carried a patient alert card since 2024, and the MHRA counted 170 Yellow Card reports of suicidal thoughts linked to finasteride between 1994 and 31 May 2025, including 19 suicides. The advice attached to those reports is blunt: stop the tablets and see a doctor.

Both treatments share the same limitation, and it is better understood before starting than after: the benefit disappears once you stop. They slow a process down, they do not correct it. Within a few months off treatment the scalp returns to the state it would have reached anyway. This is a long commitment, not a course of tablets.

Surgery: the most lasting answer

Where the follicle has gone, no product will bring it back. A transplant remains the most lasting treatment for androgenetic alopecia, precisely because it stimulates nothing: it moves hair that is already growing.

Grafts are taken from the donor area at the back and sides of the head. Those follicles are genetically indifferent to DHT. Once re-implanted on top of the head they keep that property and carry on growing normally, for life.

Two techniques dominate today. FUE removes follicular units one at a time with a micro-punch, a hollow drill under a millimetre across, then places them in tiny incisions prepared in advance. DHI uses an implanter pen that pierces the skin and delivers the graft in a single movement, which gives finer control over angle and depth.

The procedure is done under local anaesthetic, over a single day. The implanted grafts shed their shafts in the weeks that follow, a normal event that alarms a great many patients, and regrowth begins around the third month. The final result is judged at twelve months, sometimes a little later over the crown.

One condition matters more than the choice of technique: the hair loss must be stable. Operating on a scalp where alopecia is still advancing quickly, in a young patient, sets up a result that falls out of balance within a few years, leaving an intact transplanted zone marooned among native hairs that carry on disappearing. That is why medical treatment and surgery are not rivals and are frequently combined. Other situations rule surgery out altogether, and the contraindications are always checked before any date is fixed.

Alopecia areata: an autoimmune disease, never an indication for surgery

Alopecia areata has nothing to do with common baldness. It is an autoimmune disease: the immune system turns on the hair follicle and halts its growth abruptly. The classic result is one or more round patches of smooth skin that appear within weeks on an otherwise normal scalp.

The follicle is not destroyed. It is switched off. Spontaneous regrowth happens in a fair proportion of limited cases, sometimes within months, with no treatment at all. At the other extreme the disease can spread across the whole scalp and take the eyebrows, the eyelashes and the beard with it. The course of it stays unpredictable, which is what makes the condition as hard to live with as it is to treat.

Management belongs to dermatology. Topical steroids, or steroid injections into the patches, for limited disease. For extensive and stubborn cases the arrival of JAK inhibitors changed the picture: these drugs dampen the signalling pathway that keeps the immune attack going, and phase 3 trials published in the *New England Journal of Medicine* showed meaningful regrowth in a substantial share of the patients treated. They require blood monitoring and a specialist prescription.

One point is settled and worth repeating: alopecia areata is never treated with a hair transplant. Implanting grafts into an area the immune system is attacking simply exposes them to the same attack. The clinic turns these requests down.

Telogen effluvium: fix the cause, nothing more

Telogen effluvium is a diffuse shed across the whole head that follows a specific event by two to three months. Childbirth, surgery, a high fever, rapid weight loss, a psychological shock, iron deficiency, a thyroid disorder: the body tips an abnormal share of hairs into the shedding phase all at once.

Hair comes out in handfuls at the brush. It looks dramatic, and it is very nearly always reversible.

Treatment consists of identifying and correcting the trigger, then waiting. Blood tests look for iron deficiency, a thyroid imbalance, a vitamin shortfall. Supplements are justified only where the readings show a genuine lack: taking iron without a deficiency achieves nothing and is not harmless.

Density generally returns within six to nine months once the cause has been dealt with. Stacking up supplements, lotions and shampoos during that window only adds noise and makes it impossible to know what worked.

Scarring alopecia: put out the inflammation, do not expect regrowth

Scarring alopecia is the one form in which the follicle is genuinely lost. Chronic inflammation destroys the part of the follicle that holds the stem cells, and fibrous tissue takes its place. The skin turns smooth and shiny, with no visible openings.

The aim of treatment is therefore not regrowth. It is to stop the disease advancing: topical or injected steroids, antibiotics used for their anti-inflammatory effect, immunomodulators according to the exact diagnosis reached by the dermatologist, often after a biopsy. The earlier the condition is taken in hand, the more scalp is saved.

A transplant can occasionally be considered, but only months after the inflammation has been completely extinguished, and never on active disease. That decision belongs to the dermatologist and the surgeon together.

Trichotillomania: the scalp is not the problem

Trichotillomania is an impulse control disorder: the person pulls their hair out repeatedly, often without being fully aware of doing it. The affected areas show hairs broken off at uneven lengths, which sets them clearly apart from the smooth patches of alopecia areata.

No lotion treats this. Management is psychological, and habit reversal therapy, a behavioural approach that trains a competing action in place of the pulling, is the reference treatment. Medication is sometimes added. The scalp itself recovers very well once the pulling stops, provided the traction has not gone on for years.

Where to start

A consultation, not an online order. What all these situations have in common is that a wrong diagnosis leads to months lost and sometimes to pointless treatment.

If the loss is inherited and progressive, medical treatment is worth discussing early, and a hair transplant Turkey provides the lasting answer on areas that have already gone bare, once the situation has settled. If it is diffuse and recent, look for the cause before buying anything. If it draws clean round patches, it is the dermatologist you need, and quickly.
