What Is Alopecia Areata?
Alopecia areata is an autoimmune condition in which the body's immune system mistakenly targets its own hair follicles. Rather than leaving them alone as healthy tissue, the immune system disrupts the follicle's normal function, causing the affected hair to stop growing and fall out. The result is typically one or more distinct, smooth patches of hair loss that appear without warning.
Unlike the gradual miniaturisation of hair seen in androgenetic alopecia, the follicles in alopecia areata are not permanently destroyed. They remain present and capable of regrowth, which is why spontaneous remission does occur in some people. However, the condition is unpredictable: patches may resolve over months, persist for years, or spread to involve larger areas of the scalp, beard, eyebrows, eyelashes, or body hair. This unpredictability is one of the most difficult aspects of living with the condition.
Alopecia areata affects people of all ages, ethnicities, and sexes. It is one of the more common forms of hair loss seen in clinical practice and accounts for a meaningful proportion of referrals to dermatology services across the West Midlands and beyond. At Regener8 Aesthetics in Selly Oak, Birmingham, we provide thorough assessment and an honest discussion of what evidence-based aesthetic treatments can and cannot offer for this condition.
Alopecia areata is autoimmune in origin, not caused by stress, poor diet, or hair care habits alone. The follicles remain intact and capable of regrowth, which distinguishes it from scarring forms of hair loss. The course of the condition is variable and cannot be reliably predicted in advance.
Symptoms
Alopecia areata most commonly presents as one or more circular or oval patches of smooth, bare skin on the scalp. The patches typically appear quite suddenly and without preceding inflammation or obvious discomfort, though some people report a tingling, burning, or itching sensation in the affected area before hair falls out. Symptoms vary considerably between individuals.
- Smooth, well-defined bald patches on the scalp, typically round or oval in shape
- Patches that appear suddenly, sometimes overnight, without warning
- "Exclamation mark" hairs at the border of active patches, short, broken hairs that taper towards the scalp
- Hair loss affecting the beard, eyebrows, eyelashes, or body hair in addition to or instead of the scalp
- Tingling, itching, or mild discomfort in the area shortly before or during hair loss
- Nail changes including pitting, ridging, white spots, or a roughened surface (affects some people with alopecia areata)
- Multiple patches that may merge into larger areas over time
- Regrowth of fine, white or grey hair in a recovering patch before pigmented hair returns
Causes
The underlying cause of alopecia areata is an autoimmune process. In healthy hair growth, the follicle benefits from a degree of immune privilege, meaning the immune system does not recognise follicle cells as foreign and leaves them undisturbed. In alopecia areata, this privilege breaks down. T-lymphocytes (a type of white blood cell) cluster around the follicle and attack it, disrupting the normal cycle of growth. The exact reason this breakdown occurs is not fully understood, but research points to an interplay between genetic susceptibility and environmental triggers.
People with a family history of alopecia areata have a higher likelihood of developing the condition themselves. It is also associated with other autoimmune conditions including thyroid disease, vitiligo, rheumatoid arthritis, and inflammatory bowel disease. Having one of these conditions does not mean alopecia areata will develop, but it does indicate a shared immune system vulnerability.
Alopecia areata is not caused by stress alone, though significant physical or emotional stress may trigger an episode in those who are already genetically predisposed. It is not contagious, not caused by poor hygiene or diet, and not the result of excessive shampooing or heat styling. Understanding these facts matters because people with the condition frequently receive inaccurate explanations that delay appropriate assessment and treatment.
Who Is Affected?
Alopecia areata is estimated to affect around two per cent of the global population at some point during their lifetime. It is one of the most common autoimmune conditions overall and one of the leading causes of non-scarring hair loss presenting to dermatology services. It is particularly prevalent in children and young adults, with many cases first presenting before the age of 30, though it can develop at any age.
The condition affects men and women in broadly equal proportions, though the visible impact and psychological experience may differ. In men, involvement of the beard is common and can be the primary or sole site of loss. In women, scalp patches that affect parting lines or visible areas of the hairline are frequently a source of significant distress. Children with alopecia areata may face additional challenges in social settings and at school.
Risk factors for developing alopecia areata include a family history of the condition, a personal or family history of other autoimmune diseases, and, in some studies, a history of atopic conditions such as eczema, asthma, or allergic rhinitis. Those with Down syndrome have a markedly higher prevalence of alopecia areata than the general population. Psychological stress may act as a precipitating factor in susceptible individuals, though it does not cause the condition in those without an underlying autoimmune tendency.
Diagnosis and Assessment
The diagnosis of alopecia areata is usually clinical, meaning it is based on the characteristic appearance of the hair loss pattern and a careful history. In most straightforward cases, a trained practitioner can identify the condition without the need for specialist investigations. The smooth, discrete, non-scarring patches with exclamation mark hairs at the margins are distinctive and differ clearly from other causes of hair loss.
At Regener8 Aesthetics, our consultation process includes a detailed hair and scalp history alongside a thorough visual assessment. We will ask about the onset and progression of hair loss, any relevant family history, associated medical conditions, medication use, and the presence of other autoimmune features. A scalp examination helps to assess the activity and extent of the condition.
Blood tests are not required to diagnose alopecia areata, but may be recommended in certain circumstances to assess for associated conditions including thyroid dysfunction, anaemia, vitamin D deficiency, or other autoimmune markers. Where there is diagnostic uncertainty, the pattern is atypical, or the extent of loss is significant, onward referral to a consultant dermatologist is appropriate and we will discuss this openly at your appointment.
It is important to distinguish alopecia areata from other forms of hair loss that may initially appear similar. Tinea capitis (scalp ringworm) can cause patchy loss with scalp changes and is more common in children. Trichotillomania (hair pulling) may produce irregular patches. Scarring alopecias require prompt specialist assessment as follicle damage in these conditions is irreversible. Correct diagnosis is the foundation of appropriate treatment.
Evidence-Based Treatments
Treatment for alopecia areata is not straightforward, and it is important to approach the subject honestly. No current treatment addresses the underlying autoimmune mechanism permanently, and the condition's unpredictable course means that spontaneous regrowth and spontaneous relapse can both occur regardless of treatment. The goal of clinical management is to support regrowth where possible, reduce the rate of progression, and address the psychological impact of the condition.
First-Line Approaches
For adults with limited patchy alopecia areata, watchful waiting is a legitimate first step, particularly in newly presenting cases where spontaneous remission within a year is possible. Topical and intralesional corticosteroids are the most widely used treatments in dermatology practice for patchy disease. Intralesional injections, delivered by a clinician directly into the affected area, are often preferred over topical application for their superior penetration and more predictable local effect.
Medical Treatments
Topical minoxidil is sometimes used as an adjunct to support regrowth, though it does not target the autoimmune process. Contact immunotherapy (DPCP or SADBE), applied in specialist dermatology settings, works by deliberately inducing a controlled immune response to redirect the immune attack away from follicles. Systemic immunosuppressants including oral corticosteroids, methotrexate, or cyclosporin may be considered for extensive or rapidly progressive disease under consultant supervision. JAK inhibitor medications, a newer class of targeted immunotherapy, have demonstrated significant efficacy in clinical trials for alopecia areata and are increasingly available through specialist dermatology services in the UK.
PRP Therapy
Platelet-rich plasma (PRP) therapy involves concentrating your own blood's growth factors and injecting them into the scalp. For alopecia areata, the evidence base is still developing: a number of small-scale studies and case series have reported improvements in regrowth in some patients with patchy disease, and the biological rationale is plausible, as growth factors in PRP may help modulate the local immune environment and support follicle activity. However, PRP does not address the autoimmune cause of the condition, and results are variable. It is most likely to be considered as part of a broader management approach for mild-to-moderate patchy alopecia areata rather than as a standalone treatment for extensive disease. Suitability is assessed individually at consultation.
Microneedling
Scalp microneedling creates controlled micro-injuries that trigger a localised healing and growth response. In some clinical studies it has been used alongside topical agents or PRP to enhance scalp absorption and stimulate follicle activity. For alopecia areata specifically, the evidence is limited and preliminary, and it would typically be considered as an adjunct rather than a primary treatment.
Combination Approaches
Many practitioners working in hair loss take a combination approach, where multiple complementary interventions are used together. For example, PRP may be offered alongside topical treatments, with referral to a dermatologist for intralesional corticosteroids or specialist-level therapies where indicated. The most appropriate combination depends on the extent and activity of the condition, the individual's preferences, and how they have responded to prior treatment.
When Treatment May Not Be Appropriate
Extensive alopecia areata (affecting more than 50 per cent of the scalp), alopecia totalis (complete scalp loss), or alopecia universalis (loss of all body hair) are beyond the scope of aesthetic practice and require specialist dermatology management. We will always be transparent about the limits of what we offer and will facilitate appropriate referral where this is in the client's best interest.

Why Choose Regener8 Aesthetics?
At Regener8 Aesthetics in Selly Oak, we understand that a condition like alopecia areata is rarely just a physical concern. Hair loss that appears suddenly, in visible patches, and with an uncertain future can have a significant impact on confidence, identity, and daily life. Our approach to consultation begins from a position of genuine care: we want you to leave with an accurate understanding of your situation, honest information about your options, and a clear sense of what is and is not realistic for your particular pattern of hair loss.
We do not offer a one-size-fits-all treatment pathway. The assessment at your consultation will consider the extent and activity of your alopecia areata, your medical history, any previous treatments you have tried, and your personal priorities. Where aesthetic treatments such as PRP are appropriate and realistic, we will explain the evidence and the limitations clearly. Where specialist dermatology referral is indicated, we will say so without hesitation.
Our clinic serves clients from across Birmingham and the wider West Midlands, including Harborne, Edgbaston, Moseley, Kings Heath, Stirchley, Bournville, Northfield, and Selly Oak. We offer consultations in English, Farsi, and Russian, which we recognise matters enormously when discussing something as personal as hair loss.
PRP treatment at Regener8 is performed by trained clinical practitioners using established protocols. The entire process, from blood draw through to injection, takes place in a clean, unhurried clinical environment. We use a standard centrifugation protocol to produce a consistent PRP preparation, and sessions are planned around your individual response rather than a rigid, impersonal schedule.
We are committed to transparency about evidence. For alopecia areata, PRP is an emerging adjunct with a growing but still limited evidence base. We will never overstate what a treatment can achieve. Our aim is to support every client in making an informed decision, free from pressure, and grounded in an honest clinical conversation.
- Alopecia areata is an autoimmune condition: the immune system attacks hair follicles, causing patchy, non-scarring hair loss that can affect the scalp, beard, eyebrows, and body.
- The follicles remain intact, which means spontaneous regrowth is possible, but the condition's course is unpredictable and relapse can occur after remission.
- PRP therapy has an emerging evidence base for patchy alopecia areata and may support follicle activity, but does not address the underlying autoimmune process and results are variable.
- Extensive disease (alopecia totalis or universalis) requires specialist dermatology management and is outside the scope of aesthetic practice.
- The psychological impact of alopecia areata is significant and should be acknowledged and supported alongside any physical treatment approach.
