Alopecia Areata Treatment in London: Understanding Your Options in 2026
Medically reviewed by a GMC-registered doctor at The PRP Clinic | Last updated: February 2026
Waking up to find a smooth, round patch of hair missing from your scalp is an alarming experience. For the approximately 2% of the population affected by alopecia areata, this is a reality that can be deeply distressing — not only because of the visible hair loss itself, but because of the uncertainty that follows. Will it spread? Will it grow back? What can actually be done?
The good news is that 2026 represents the most hopeful period in the history of alopecia areata treatment. Our understanding of the condition has advanced enormously, three JAK inhibitor medications have now received FDA approval specifically for severe cases, and regenerative treatments like PRP and exosome therapy are showing genuine promise for promoting regrowth. The era of simply being told "wait and see if it comes back on its own" is ending.
This guide explains what alopecia areata is, how it differs from other types of hair loss, what the latest evidence-based treatment options are, and how The PRP Clinic can help as part of a comprehensive management plan.

What is alopecia areata?
Alopecia areata is a chronic autoimmune condition in which the body's immune system mistakenly identifies hair follicles as foreign and attacks them, causing non-scarring hair loss. Unlike androgenetic alopecia (pattern hair loss driven by genetics and hormones), alopecia areata is fundamentally an immune system problem.
The hallmark presentation is one or more round, smooth patches of hair loss on the scalp. The skin within these patches appears normal — there is no scarring, scaling, or visible inflammation, which distinguishes it from other causes of patchy hair loss. Under close examination, characteristic "exclamation mark" hairs — short, tapered hairs that are narrower at the base — may be visible at the edges of active patches.
Alopecia areata can affect anyone at any age, though it most commonly begins before age 30. It affects men and women equally. The condition can take several forms. Patchy alopecia areata involves one or more discrete patches of hair loss. Alopecia totalis involves complete loss of scalp hair. Alopecia universalis involves complete loss of all body hair. Alopecia ophiasis affects hair in a band-like pattern around the sides and back of the scalp.
The critical distinction from pattern hair loss is that in alopecia areata, the follicles themselves are not destroyed. The immune attack forces follicles into a dormant state, but the underlying follicle structure remains intact. This is why regrowth is possible — sometimes spontaneously, and increasingly with treatment — even after extensive hair loss.
Why alopecia areata happens
Alopecia areata occurs when the immune system's T-cells target hair follicles, disrupting the normal growth cycle and causing hairs to detach and follicles to enter a dormant phase. The exact trigger varies between individuals, but several factors contribute.
Genetic predisposition plays a significant role. Having a first-degree relative with alopecia areata increases your risk, and specific genes involved in immune regulation (particularly the HLA gene complex) are associated with susceptibility.
Immune dysregulation is the core mechanism. The immune system's normal tolerance of hair follicles breaks down, likely involving disruption of the "immune privilege" that normally protects follicles from immune attack. This involves overactivation of the JAK-STAT signalling pathway, which is why JAK inhibitor medications have been so effective.
Environmental triggers can initiate or worsen episodes. These include severe emotional stress, viral infections, physical trauma, and hormonal changes. Many patients report their first episode occurring during a period of significant stress.
Associated autoimmune conditions are common. Approximately 20-25% of alopecia areata patients have another autoimmune condition, most commonly thyroid disease (particularly Hashimoto's thyroiditis), vitiligo, or atopic conditions (eczema, asthma, hay fever).
The 2026 treatment landscape
The treatment options for alopecia areata have expanded dramatically, particularly for moderate to severe cases.
PRP therapy for alopecia areata
PRP therapy offers a targeted, local approach to promoting regrowth in alopecia areata. When injected into affected areas, PRP delivers concentrated growth factors (PDGF, VEGF, TGF-beta, IGF-1) and anti-inflammatory molecules directly to the follicle environment.
Research has demonstrated that PRP can reduce the local inflammation driving the autoimmune attack on follicles, stimulate dormant follicles to re-enter the growth phase, improve blood supply to affected areas, and promote healthier, stronger regrowth. A study comparing PRP delivery methods found that PRP injections, PRP via fractional laser, and PRP via microneedling were all effective in promoting hair regrowth in alopecia areata patients.
PRP is most effective for patchy alopecia areata and can be an excellent option for patients who prefer a localised, non-systemic treatment, want to avoid the potential side effects of oral medications, have milder or more localised disease, or want to combine PRP with other treatments for a multi-targeted approach.
At The PRP Clinic, we use PRP as part of a comprehensive alopecia areata management plan, often combining it with nutritional optimisation and, where appropriate, coordinating with dermatologists who may prescribe systemic treatments.
Exosome therapy
Exosome therapy is an emerging option for alopecia areata that shows significant promise. Exosomes deliver concentrated stem cell-derived growth factors and anti-inflammatory signalling molecules. Research suggests they not only stimulate follicle regeneration but also reduce scalp inflammation and improve the overall follicle environment — addressing both the immune-mediated damage and the regenerative needs of dormant follicles.
At The PRP Clinic, ExoRevive exosome treatments can be considered as part of an alopecia areata treatment plan, particularly for patients seeking the most advanced regenerative options.
JAK inhibitors
The development of JAK inhibitors represents the single most significant advance in alopecia areata treatment in decades. Three JAK inhibitors are now FDA-approved for severe alopecia areata. Baricitinib (Olumiant) was approved in June 2022 for adults. Ritlecitinib (Litfulo) was approved in June 2023 for adults and adolescents aged 12 and above. Deuruxolitinib (Leqselvi) was approved in July 2024 for adults.
Clinical trial results have been impressive. With baricitinib, 35-40% of patients achieved substantial hair recovery (SALT score of 20 or less) at 36 weeks. Deuruxolitinib showed 30% of patients achieving 80% or more scalp hair coverage at 24 weeks. Long-term data shows continued improvement with sustained use.
JAK inhibitors work by blocking the JAK-STAT signalling pathway that drives the autoimmune attack on follicles. They are systemic (oral) medications that require specialist prescription, regular blood monitoring, and careful consideration of potential side effects.
Important: The PRP Clinic does not prescribe JAK inhibitors. These are specialist dermatological medications that require ongoing monitoring. However, our doctors can discuss whether a referral to a dermatologist for JAK inhibitor assessment might be appropriate alongside the regenerative treatments we offer. Many leading clinicians now advocate a combination approach — JAK inhibitors to control the immune system alongside PRP to nourish the scalp — which often works better than either approach alone.
Other established treatments
Corticosteroid injections remain a standard first-line treatment for patchy alopecia areata. Intralesional triamcinolone injections can promote regrowth in individual patches, though relapse is common. Topical corticosteroids may be used for milder cases. Our doctors can administer intralesional steroid treatments where appropriate.
Topical immunotherapy (DPCP/SADBE) involves applying a chemical sensitiser to the scalp to redirect the immune response. It can be effective but requires specialist administration.
Alopecia areata is no longer untreatable. Our doctors can assess your condition and build a personalised plan combining the most effective options for your specific situation.

The importance of investigation and holistic support
Alopecia areata does not exist in isolation. Thorough investigation can identify associated conditions and contributing factors that, when addressed, improve treatment outcomes.
At The PRP Clinic, our assessment includes comprehensive blood testing to check for thyroid function (given the strong association between thyroid autoimmunity and alopecia areata), iron and ferritin levels, vitamin D, zinc, vitamin B12, and inflammatory markers. Identifying and correcting nutritional deficiencies is particularly important because even with effective immune management, follicles need adequate nutrients to produce healthy hair.
We design personalised supplement protocols based on your blood results, ensuring your body has the building blocks needed to support regrowth. This holistic approach — combining regenerative treatments with nutritional optimisation — is what produces the best outcomes for our alopecia areata patients.
The psychological impact: we understand
Alopecia areata carries a significant psychological burden. Research consistently shows higher rates of anxiety and depression in alopecia areata patients. The unpredictable nature of the condition — not knowing whether patches will spread or resolve — adds a layer of emotional distress that is often underestimated by healthcare providers.
At The PRP Clinic, we take the emotional impact seriously. Our doctors provide compassionate, informed care. We set realistic expectations while offering genuine hope based on the advances available in 2026. We understand that this is not "just cosmetic" — it affects how you feel about yourself, your confidence, and your quality of life.
You are not alone, and this is not hopeless. Let us help you take the first step.

Frequently asked questions
What is alopecia areata?
An autoimmune condition where the immune system attacks hair follicles, causing round patches of non-scarring hair loss. It affects approximately 2% of the population.
Can PRP help alopecia areata?
Yes. PRP reduces local inflammation, stimulates dormant follicles, and promotes regrowth. It is most effective for patchy alopecia areata and can be combined with other treatments.
What are JAK inhibitors?
Oral medications (baricitinib, ritlecitinib, deuruxolitinib) that block the immune pathways driving alopecia areata. Three are now FDA-approved for severe cases.
Does alopecia areata hair grow back?
In many cases, yes. Follicles are preserved in alopecia areata, meaning regrowth is possible — sometimes spontaneously, and increasingly with treatment.
How is it diagnosed?
Clinically, based on the characteristic pattern of smooth patches with preserved follicle openings. Blood tests check for associated conditions and nutritional factors.
