Who do you see for hair loss depends on the cause, severity, and whether you are accessing NHS or private care. In the UK, your GP is usually the best first port of call — they can investigate underlying causes, initiate treatment, and refer you onward if needed. From there, you may be directed to a dermatologist (the primary medical specialist for hair and scalp conditions), or choose to consult a trichologist privately. Understanding the differences between these professionals, when to seek help, and what to expect from diagnosis and treatment can make a significant difference to your outcome.

Which NHS or Private Specialist Treats Hair Loss?

GPs are the first point of contact, with dermatologists being the primary specialists for most hair loss conditions; trichologists are private-only, non-medically qualified practitioners who cannot prescribe or diagnose systemic disease.

Hair loss can be assessed and managed by several different healthcare professionals in the UK, depending on the underlying cause, severity, and whether you are seeking NHS or private care. Understanding who to approach first can save considerable time and ensure you receive the most appropriate assessment.

The main specialists involved in hair loss care include:

• General Practitioners (GPs): Usually the first point of contact, able to assess, investigate, and refer

• Dermatologists: NHS or private consultants specialising in skin, hair, and nail conditions — the primary specialist for most hair loss conditions

• Trichologists: Non-medical specialists focused exclusively on scalp and hair health, available privately only

• Endocrinologists or Gynaecologists: Involved only when hair loss is clearly linked to an underlying hormonal condition such as thyroid disease or polycystic ovary syndrome (PCOS); dermatology remains the lead specialty for hair loss itself

On the NHS, access to a dermatologist typically requires a GP referral. Privately, you can self-refer to a dermatologist or trichologist without waiting for a GP appointment. The British Association of Dermatologists (BAD) maintains a 'Find a Dermatologist' directory, and the Institute of Trichologists holds a register of members — both can help you identify reputable practitioners.

Important note on trichologists: Trichology is not a statutorily regulated profession and 'trichologist' is not a protected title in the UK. Trichologists are not medically qualified doctors; they cannot prescribe medication or diagnose systemic disease. When choosing a trichologist, check that they are registered with a recognised body such as the Institute of Trichologists or the British Association of Hair and Nail Specialists. For any hair loss with a suspected medical cause, a GP or dermatologist is the most appropriate first step.

If scarring alopecia or an inflammatory scalp condition is suspected, prompt dermatology assessment is important, as early treatment can help prevent permanent hair follicle damage.

When to See Your GP About Hair Loss

See your GP promptly if hair loss is sudden, patchy, rapidly progressive, or accompanied by symptoms such as fatigue, scalp inflammation, or hormonal changes, as underlying medical causes need to be excluded.

Most people experiencing hair loss should begin by consulting their GP, particularly when the hair loss is sudden, widespread, or accompanied by other symptoms. A GP can rule out underlying medical causes before any specialist referral is considered.

You should make an appointment with your GP if you notice:

• Sudden or patchy hair loss appearing over a short period

• Hair loss accompanied by fatigue, weight changes, or skin changes (which may suggest thyroid dysfunction)

• Scalp inflammation, redness, scaling, or pain — particularly with perifollicular redness or shiny, scarred-looking skin, which may indicate scarring alopecia

• Rapidly progressive hair loss

• Hair loss following a significant illness, surgery, or period of high stress

• Hair thinning associated with irregular periods, acne, or other hormonal symptoms in women

• Hair loss in children or teenagers, especially with scalp scaling, pustules, or a boggy swelling (kerion), which may indicate a fungal infection (tinea capitis) requiring urgent treatment

Traction alopecia — hair loss caused by tight hairstyles, extensions, or chemical treatments — is a preventable cause. Changing hair practices promptly may prevent permanent scarring; speak to your GP or a dermatologist if you are concerned.

Gradual thinning at the crown or temples — particularly in men — is often androgenetic alopecia (male-pattern baldness), which is not usually a medical emergency. However, even in these cases, a GP visit is worthwhile to exclude contributing factors such as iron deficiency anaemia or thyroid disease, both of which are common and treatable causes of hair shedding.

The NHS advises that hair loss is rarely a sign of something serious, but it can significantly affect mental wellbeing. GPs are trained to assess the psychological impact of hair loss and can refer patients to appropriate support services where needed. Do not delay seeking advice if hair loss is causing you distress — early assessment often leads to better outcomes, particularly for inflammatory or autoimmune conditions where prompt treatment can limit further loss.

Referral Pathways: Dermatologists and Trichologists Explained

NHS dermatology referral requires a GP, whilst private dermatologists and trichologists can be accessed directly; trichologists cannot prescribe medication or diagnose systemic conditions.

Once your GP has completed an initial assessment, they may refer you to a specialist depending on the suspected diagnosis. In the UK, the two most common specialist pathways for hair loss are dermatology (via the NHS or privately) and trichology (private only).

NHS Dermatology Referral: Your GP can refer you to an NHS dermatologist if they suspect a condition such as alopecia areata, scarring alopecia (e.g., lichen planopilaris or frontal fibrosing alopecia), or hair loss that has not responded to initial treatment. Waiting times vary by region. In some areas, a GP may first refer to a community dermatology service, a dermatology nurse-led clinic, or a GP with Extended Roles (GPwER) in dermatology, before escalating to a consultant dermatologist.

Private Dermatology: Seeing a private dermatologist typically offers faster access, though waiting times and fees vary considerably by provider and region. Private consultants can prescribe the same treatments available on the NHS and may have access to additional therapies or clinical trials. Contact individual clinics or use the BAD 'Find a Dermatologist' directory for current information on availability and fees.

Trichologists: A trichologist specialises solely in hair and scalp conditions. They may use tools such as magnification or trichoscopy to assess hair density and scalp health, and can recommend over-the-counter treatments, lifestyle modifications, and nutritional support. However, trichoscopy and dermoscopy as diagnostic tools are standard practice in dermatology; trichologists cannot diagnose systemic disease or prescribe medication. They should refer you to a GP or dermatologist if a medical cause is suspected.

Choosing between these pathways often depends on your specific symptoms, urgency, and personal circumstances. Many patients benefit from input from both a trichologist and a dermatologist at different stages of their care.

How Hair Loss Is Diagnosed in the UK

Diagnosis combines clinical history, physical examination, and targeted blood tests such as ferritin and thyroid function; scalp biopsy or trichoscopy may be used in specialist settings.

Diagnosing hair loss accurately is essential, as different types require very different treatments. A thorough assessment typically combines a clinical history, physical examination, and targeted investigations.

Clinical history will usually cover:

• Duration and pattern of hair loss

• Family history of hair loss

• Recent illnesses, surgeries, or significant life stressors

• Dietary habits and any nutritional deficiencies

• Current medications (many drugs can cause hair shedding as a side effect)

• Hormonal history, including pregnancy, menopause, or contraceptive use

Physical examination involves assessing the pattern of loss, scalp condition, hair shaft quality, and performing a hair pull test — gently tugging a small cluster of hairs to assess how many shed, which helps distinguish active shedding from stable loss.

Investigations commonly requested by a GP or dermatologist:

NICE CKS guidance recommends a targeted, clinically indicated approach to blood tests rather than routine broad-panel testing. Tests are selected based on the history and examination findings:

• Full blood count (to check for anaemia)

• Serum ferritin (iron stores — a key driver of telogen effluvium)

• Thyroid function tests (TSH)

• Androgen profile (e.g., total testosterone, SHBG) — in women with features of hyperandrogenism such as irregular periods, acne, or hirsutism

• Additional tests (e.g., vitamin D, B12, inflammatory markers) only if specifically indicated by the clinical picture

Where a fungal infection is suspected — particularly in children with scalp scaling, hair loss, or a kerion — fungal microscopy, hair sampling, and culture should be performed promptly, as tinea capitis requires systemic antifungal treatment.

In specialist settings, a scalp biopsy may be performed to distinguish between non-scarring and scarring alopecias — a distinction that significantly affects prognosis and treatment. Trichoscopy (dermoscopy of the scalp) is used in dermatology to assess hair follicle density and identify characteristic patterns associated with specific diagnoses.

Treatment Options Available Through the NHS and Privately

Treatment depends on the underlying cause and ranges from over-the-counter topical minoxidil to prescription medicines, corticosteroids, and private procedures such as PRP or hair transplant surgery.

Treatment for hair loss in the UK depends entirely on the underlying cause. Some conditions respond well to medical therapy, whilst others may require procedural interventions or simply watchful waiting with lifestyle support.

Topical minoxidil (e.g., Regaine 2% or 5%): Licensed for androgenetic alopecia in both men and women, topical minoxidil is available over the counter as a pharmacy medicine and is not routinely prescribed on the NHS. Common side effects include scalp irritation and, rarely, unwanted facial hair growth. Refer to the patient information leaflet or speak to a pharmacist before starting.

Finasteride 1 mg: A prescription-only oral medicine licensed for male-pattern baldness in men. It works by inhibiting 5-alpha reductase, reducing levels of dihydrotestosterone (DHT) that miniaturise hair follicles. Important: For hair loss, finasteride is generally available on private prescription only and is not routinely prescribed on the NHS. It is contraindicated in women who are or may become pregnant — women of childbearing potential must not handle crushed or broken tablets. The MHRA has issued Drug Safety Updates highlighting risks of sexual dysfunction (reduced libido, erectile dysfunction, ejaculatory disorders) and psychiatric effects including depression and suicidal ideation. These effects may persist after stopping the medicine. If you experience mood changes, depression, or thoughts of self-harm whilst taking finasteride, stop the medicine and seek medical advice promptly. Discuss the benefits and risks fully with your prescriber before starting.

Corticosteroids: Used for alopecia areata — administered as intralesional injections, topical preparations, or short courses of oral steroids, depending on the extent of involvement.

Immunotherapy (DPCP): Available in specialist NHS centres for extensive alopecia areata.

Treatment of underlying conditions: Correcting iron deficiency, thyroid disease, or hormonal imbalance often leads to significant hair regrowth.

Oral minoxidil: Increasingly used off-label under medical supervision for various hair loss conditions. It is not licensed for this indication in the UK. Risks include fluid retention (oedema), low blood pressure (hypotension), and increased heart rate (tachycardia). Blood pressure and cardiovascular status should be monitored. Oral minoxidil should only be used under the supervision of a qualified prescriber.

Spironolactone: An off-label option sometimes used in women with androgenetic alopecia or hair loss associated with hyperandrogenism, typically under specialist supervision with appropriate monitoring.

Platelet-rich plasma (PRP) therapy and low-level laser therapy (LLLT): Available privately. The evidence base for both is currently limited and variable in quality; neither is routinely recommended in NHS care. Set realistic expectations and seek treatment only from reputable, regulated providers.

Hair transplant surgery: Available privately. Ensure any clinic you consider is registered with the Care Quality Commission (CQC) and that the operating surgeon is registered with the General Medical Council (GMC). Avoid unregulated providers or clinics making unsubstantiated claims.

Reporting side effects: If you experience a suspected side effect from any medicine used for hair loss, report it via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk or using the Yellow Card app.

It is important to have realistic expectations — most treatments slow or halt further loss rather than fully restoring previous density. Any use of medicines outside their licensed indications should be discussed carefully with a qualified prescriber.

Getting the Most From Your Hair Loss Appointment

Bring photographs of hair loss progression, a timeline of changes, and a full medication list to maximise the value of your consultation with a GP, dermatologist, or trichologist.

Whether you are seeing your GP, a dermatologist, or a trichologist, preparing thoroughly for your appointment will help ensure you receive the most accurate assessment and appropriate management plan.

Before your appointment, consider:

• Photographing your hair loss over time — images showing the progression of thinning or patchy areas are extremely useful for clinicians

• Writing a timeline of when you first noticed changes and any events that preceded them (illness, stress, dietary changes, new medications)

• Listing all current medications and supplements, including contraceptives, as many drugs — including anticoagulants, retinoids, and antidepressants — are associated with hair shedding

• Noting any family history of hair loss on both maternal and paternal sides

During the appointment, do not hesitate to ask:

• What type of hair loss do I have, and what is causing it?

• Are there investigations I should have?

• What are my treatment options, and what evidence supports them?

• What results can I realistically expect, and over what timeframe?

• What are the possible side effects, and what should I do if I experience them?

• How will my treatment be monitored, and when should I return or seek further advice?

Hair loss can have a profound impact on self-esteem and mental health. If you feel your concerns are not being taken seriously, you are entitled to ask for a second opinion or seek a private consultation. Alopecia UK is a patient charity offering peer support and signposting to specialist services, which many people find invaluable alongside clinical care. The BAD also produces patient information leaflets on specific types of hair loss, including alopecia areata, male-pattern hair loss, and female-pattern hair loss, which are freely available on their website.

Early, informed engagement with the right specialist gives you the best chance of an accurate diagnosis and effective management.
