What Should You Tell Your Practitioner Before PRP Hair Treatment?

Hair thinning and loss are concerns that affect a significant number of people across all ages, genders, and backgrounds. Whether you have noticed a gradual change in your hair density, increased shedding, or visible scalp through once-thicker hair, it is entirely understandable to begin exploring your options. Platelet-Rich Plasma (PRP) hair treatment has attracted considerable interest in recent years as a non-surgical approach to hair rejuvenation, and many patients in London are researching the procedure before booking a consultation.

One of the most important — and often overlooked — aspects of preparing for PRP hair treatment is understanding what information you should share with your practitioner beforehand. Your medical history, lifestyle factors, current medications, and individual health circumstances all play a meaningful role in determining whether PRP hair treatment may be appropriate for you and what results may realistically be achievable.

This article is designed to help you feel informed, prepared, and confident ahead of your consultation, covering the key disclosures, questions, and considerations you may wish to bring to your appointment.

Before undergoing PRP hair treatment, you should disclose your full medical history, any current medications or supplements, known allergies, previous hair loss treatments, scalp conditions, and relevant lifestyle factors such as smoking or alcohol consumption. This information allows your practitioner to assess individual suitability, identify any contraindications, and tailor an appropriate treatment approach for you.

Platelet-Rich Plasma (PRP) therapy for hair loss is a procedure that uses your own blood to produce a concentrated solution of platelets, which are then injected into areas of the scalp where hair thinning or loss is present.

The process begins with a small blood draw, typically from the arm. The blood is then placed in a centrifuge machine, which spins it at high speed to separate the platelet-rich plasma from the other blood components. The resulting PRP solution, which contains a higher concentration of platelets than normal blood, is then carefully injected into targeted areas of the scalp.

PRP is considered a biologically derived treatment, as it uses the patient's own blood. This approach is often described as autologous, meaning the substance used in the treatment comes from the individual themselves, which significantly reduces the risk of allergic reaction or rejection.

PRP hair treatment is not a hair transplant and does not involve surgery. It is typically considered as part of a broader approach to hair health and rejuvenation. As with all aesthetic treatments, outcomes vary between individuals, and PRP is not suitable for everyone. A thorough consultation with a qualified practitioner is essential before proceeding.

To understand why your health disclosures matter so much, it helps to have a basic understanding of how PRP is believed to work at a biological level.

Platelets are tiny cells in the blood that are primarily known for their role in clotting when we experience a wound or injury. However, platelets also contain a range of growth factors — proteins that play an important role in tissue repair, cellular regeneration, and the stimulation of new cell growth.

When PRP is injected into the scalp, these growth factors are released into the surrounding tissue. The theory is that this concentrated delivery of growth factors may help to stimulate dormant or weakened hair follicles, encourage blood supply to the scalp, and support the conditions in which hair growth may be possible.

Hair follicles go through cycles of growth (anagen), transition (catagen), and rest (telogen). In cases of hair thinning or loss, follicles may be spending more time in the resting phase or becoming progressively miniaturised. PRP is thought to work by potentially extending the active growth phase and supporting follicle health.

It is important to note that while there is a growing body of clinical evidence supporting the potential of PRP in hair rejuvenation, research is ongoing and outcomes are not guaranteed. Results vary depending on the underlying cause of hair loss, the individual's health status, and various other factors — many of which relate directly to the information you share with your practitioner before treatment.

Many patients are understandably focused on the treatment itself — how it feels, how long it takes, and what results they might expect. However, the information you share before your PRP hair treatment is equally significant, both for your safety and for the appropriateness of the procedure.

A thorough pre-treatment consultation allows your practitioner to:

• Identify any medical conditions that may affect suitability
• Recognise potential contraindications (factors that may make the treatment inadvisable)
• Understand the likely cause and pattern of your hair loss, which helps in setting realistic expectations
• Adjust the treatment approach based on your individual circumstances
• Ensure that any medications or supplements you are taking will not interfere with the procedure or increase risk

Sharing accurate and complete information is not simply a formality — it is a fundamental part of receiving appropriate aesthetic care. Your practitioner is not there to judge your lifestyle or health history. They need this information to serve your best interests.

Your full medical history is one of the most important areas of disclosure before PRP hair treatment. Your practitioner will typically ask about both current and past conditions, so it is helpful to think carefully about any health matters that may be relevant.

Conditions that may be relevant include:

• Blood disorders or clotting conditions — since PRP involves drawing and processing your blood, conditions affecting platelet function, clotting, or bleeding may be significant
• Active infections — particularly any scalp infections, skin conditions, or systemic infections
• Autoimmune conditions — such as lupus or alopecia areata, which may influence the type and cause of hair loss as well as treatment suitability
• Liver disease — this can affect platelet function and overall suitability
• Cancer or a history of cancer — particularly blood cancers such as leukaemia, which are considered contraindications to PRP
• Platelet dysfunction syndromes — any conditions that affect how your platelets function
• Skin conditions affecting the scalp — such as psoriasis, seborrhoeic dermatitis, or eczema, which your practitioner will need to assess
• Diabetes — which may affect healing and tissue response
• Thyroid conditions — as thyroid dysfunction is a common and treatable cause of hair loss that may need to be addressed separately before or alongside any PRP treatment

This is not an exhaustive list, and your practitioner will guide the discussion during your consultation. The key point is to be as thorough and transparent as possible.

Your current medications — both prescription and over-the-counter — are another essential area of disclosure before PRP hair treatment.

Medications and supplements that may be relevant include:

• Blood thinners (anticoagulants) — such as warfarin, aspirin, or direct oral anticoagulants (DOACs). These can affect bleeding at the injection site and may interact with the procedure
• Non-steroidal anti-inflammatory drugs (NSAIDs) — such as ibuprofen, which may affect platelet function
• Corticosteroids — including steroid injections or long-term oral steroids, which can affect tissue healing
• Immunosuppressant medications — which may alter the body's response to the treatment
• Hormonal treatments — including the contraceptive pill or hormone replacement therapy (HRT), which can influence hair health
• Retinoids — including isotretinoin (commonly prescribed for acne), which may affect skin and tissue response
• Supplements — including fish oil, vitamin E, garlic, or high-dose vitamin supplements, which can have blood-thinning properties

Many patients do not consider supplements to be "medications," but some can have a significant effect on platelet function and should always be disclosed. Your practitioner may advise you to pause certain medications or supplements before treatment, but you should never stop prescribed medication without the guidance of your prescribing doctor or GP.

Sharing your history of previous hair loss treatments is highly relevant to your consultation. Your practitioner will want to understand what approaches you have already tried, how your hair and scalp responded, and whether any treatments are ongoing.

Relevant previous treatments may include:

• Minoxidil (topical or oral) — a commonly used medication for hair loss; your practitioner will want to know if you are using it and for how long
• Finasteride or dutasteride — hormonal medications prescribed for certain types of hair loss
• Previous PRP courses — including when they were performed, how many sessions, and any response you noticed
• Hair transplant surgery — including the technique used and when it was performed
• Low-level laser therapy (LLLT) — sometimes used alongside other hair treatments
• Scalp microneedling — another treatment sometimes used for hair health
• Steroid injections into the scalp — which may be used for certain types of alopecia

Understanding your treatment history helps your practitioner build a fuller picture of how your hair and scalp have responded over time and allows them to plan the most appropriate pathway for you.

One of the most clinically significant factors in any hair loss consultation is the underlying cause. PRP hair treatment may be more appropriate for some types of hair loss than others, and your practitioner will want to explore this carefully.

Common types of hair loss include:

• Androgenetic alopecia — sometimes called male or female pattern hair loss, this is the most common type and is related to hormonal and genetic factors
• Telogen effluvium — a form of diffuse shedding often triggered by stress, illness, nutritional deficiency, hormonal change, or significant life events
• Alopecia areata — an autoimmune condition causing patchy hair loss
• Traction alopecia — caused by prolonged tension on the hair, often from tight hairstyles
• Scarring alopecias — which involve destruction of the hair follicle and may not respond to PRP

It is worth noting that some causes of hair loss, such as nutritional deficiencies or thyroid dysfunction, may need to be identified and addressed through blood tests and appropriate treatment before aesthetic interventions are considered. Your practitioner may recommend you see your GP for investigation before proceeding, and this is entirely appropriate and patient-centred advice.

If you want a practical overview of the appointment sequence itself, this step-by-step guide to what happens during a PRP hair treatment appointment can help you prepare.

Certain lifestyle habits and factors can influence both your suitability for PRP hair treatment and the quality of results you may experience. Being open about these during your consultation allows your practitioner to give you the most accurate guidance possible.

Key lifestyle factors to disclose include:

• Smoking — smoking is known to impair blood circulation, tissue oxygenation, and healing. It may reduce the effectiveness of PRP and is generally considered an unfavourable factor for regenerative treatments
• Alcohol consumption — regular or heavy alcohol use can affect platelet function and the body's ability to heal and regenerate
• Diet and nutrition — significant dietary restrictions, disordered eating, or known nutritional deficiencies (such as iron, zinc, vitamin D, or biotin) can directly contribute to hair loss and may affect treatment response
• Exercise levels — generally a positive factor, as good cardiovascular health supports scalp circulation, though very intense training may sometimes exacerbate stress-related hair loss
• Stress levels — both acute and chronic stress are known contributors to hair shedding (telogen effluvium), and this context is valuable for your practitioner to understand
• Sleep — chronic sleep deprivation can affect cellular repair and hormone regulation
• Hair care habits — including frequent heat styling, chemical treatments, extensions, or tight hairstyles

None of these factors automatically disqualify you from PRP treatment, but they all help your practitioner understand your overall health picture and provide more accurate, personalised guidance.

Although PRP uses your own blood and is therefore largely free from external allergens, there are still allergy-related disclosures that are relevant to your appointment.

You should inform your practitioner of any known allergies, including:

• Local anaesthetics — a topical numbing cream or local anaesthetic may be applied to the scalp before injection to improve comfort. Lidocaine or related agents are commonly used, and allergy to these is important to disclose
• Latex — allergy to latex is relevant as gloves and certain equipment used in the procedure may contain latex
• Any previous reactions to injectable or skin treatments — even if the cause was not clearly identified
• Antibiotic allergies — relevant if any topical or oral antibiotics are used as part of the aftercare protocol

Disclosing your allergy history is a standard and important part of any medical or aesthetic procedure, and your practitioner will ask about this as part of a thorough pre-treatment assessment.

PRP hair treatment is not appropriate for everyone, and a professional consultation is the only way to assess individual suitability. That said, it is worth understanding the types of concerns that may prompt someone to explore whether PRP could be relevant to them.

You may wish to consider a consultation if you have noticed:

• Progressive thinning of the hair at the crown, temples, or hairline
• Increased shedding that does not appear to be resolving over time
• Reduced hair density or volume, particularly after illness, hormonal changes, or periods of significant stress
• Visible scalp through the hair, especially in areas where hair was previously denser
• Hair that appears finer or more fragile than it once did

A consultation does not commit you to any treatment. It is an opportunity to have your concerns assessed by a qualified professional, ask questions, and explore what options — if any — may be relevant to your individual circumstances.

Elective PRP hair treatment is generally considered for adults aged 18 and over, and younger patients require careful medical assessment before any procedure is considered.

If you are curious about skin rejuvenation treatments that may complement your overall aesthetic goals alongside hair treatment, a consultation can also explore a broader range of options appropriate to you.

It is important to approach PRP hair treatment with realistic expectations. As with all aesthetic procedures, outcomes vary between individuals, and results are not guaranteed.

Potential benefits that may be discussed during consultation include:

• Possible improvement in hair density and thickness over a course of treatments
• Potential stimulation of dormant hair follicles in areas of thinning
• Generally considered a well-tolerated, minimally invasive approach
• Uses the patient's own blood, reducing the risk of allergic reaction
• May be combined with other hair health strategies for a more comprehensive approach

Limitations and important considerations include:

• Results are not guaranteed and vary significantly between individuals
• Multiple treatment sessions are typically recommended, and results generally take time to become apparent — often several months
• PRP is unlikely to produce results in areas where follicles are completely inactive or where scarring has occurred
• Maintenance treatments may be required to sustain any improvement
• The underlying cause of hair loss should ideally be identified and, where possible, managed alongside PRP treatment
• PRP is not a substitute for medical treatment where an underlying condition is responsible for hair loss

Your practitioner should provide a balanced, honest discussion of what is and is not likely to be achievable based on your individual circumstances, hair loss pattern, and health history.

Following PRP hair treatment, your practitioner should provide you with clear aftercare instructions tailored to your individual treatment. General considerations that are commonly discussed include:

• Avoid washing the hair or scalp for the first 24 hours following treatment, unless advised otherwise
• Avoid vigorous exercise on the day of treatment, as increased blood flow and sweating may affect the treated area
• Avoid swimming pools, saunas, or steam rooms for at least 48 hours after treatment
• Minimise the use of styling products directly after treatment, particularly those containing harsh chemicals
• Avoid anti-inflammatory medications such as ibuprofen in the days immediately following treatment, as inflammation may be part of the natural healing and growth factor response — discuss any medication changes with your prescribing doctor
• Sun protection for the scalp — if the scalp is exposed to sunlight, appropriate protection is advisable
• Stay well hydrated and maintain a balanced diet to support overall health during the recovery period
• Attend follow-up appointments as recommended by your practitioner, who will monitor your response and guide your ongoing treatment plan

For patients also exploring Profhilo for fine lines and skin quality or other facial rejuvenation options, aftercare guidance may differ and will always be discussed individually during your appointment.

• Sharing your full and accurate medical history, medications, and lifestyle information before PRP hair treatment is essential for an appropriate consultation
• PRP hair treatment uses your own blood to deliver concentrated growth factors to the scalp; results vary and are not guaranteed
• The underlying cause of your hair loss is an important factor in determining whether PRP may be relevant to your circumstances
• Certain medical conditions, medications, and lifestyle factors may affect your suitability for PRP or the results you may experience
• PRP is not suitable for everyone, and individual assessment by a qualified practitioner is the only way to determine appropriateness
• Realistic expectations, combined with an understanding of limitations, help patients make genuinely informed decisions

How many PRP hair treatment sessions are typically recommended?

Most practitioners suggest an initial course of three to four sessions, typically spaced four to six weeks apart. This is followed by an assessment of response before any further sessions are planned. Maintenance treatments may be recommended at intervals thereafter to help sustain any improvement. The exact protocol will be determined during your consultation based on your individual needs, hair loss pattern, and response to treatment. No standard protocol guarantees specific outcomes, and the approach should always be personalised.

Is PRP hair treatment painful?

PRP injections into the scalp can cause some discomfort, as the scalp contains numerous nerve endings. Most practitioners apply a topical numbing cream or local anaesthetic before the injections to improve comfort levels during the procedure. The degree of discomfort experienced varies between individuals. Some people report a mild stinging or pressure sensation during injections, while others find it relatively well tolerated. You should discuss pain management options with your practitioner during your consultation if this is a concern for you.

Are there any situations where PRP hair treatment would not be recommended?

Yes. There are several situations where PRP hair treatment may not be considered appropriate. These include active scalp infections, certain blood disorders, low platelet counts, a history of blood cancers such as leukaemia or lymphoma, use of certain medications such as anticoagulants, and some autoimmune conditions. Pregnancy and breastfeeding may also be relevant contraindications. This is why a thorough pre-treatment consultation and honest disclosure of your medical history is so important. Suitability can only be determined on an individual basis by a qualified practitioner.

How soon can I expect to see results from PRP hair treatment?

Hair growth is a slow biological process, and visible changes following PRP treatment are not typically immediate. Most patients are advised that noticeable improvement — if it occurs — may become more apparent from around three to six months after commencing a treatment course. Some individuals may observe earlier changes in hair texture or shedding patterns. It is important to have realistic expectations and to understand that individual responses vary considerably. Your practitioner should guide you on what to look for and when it is appropriate to reassess your progress.

Can PRP hair treatment be combined with other hair loss treatments?

PRP is sometimes considered as part of a broader hair health strategy and may be used alongside other approaches such as topical or oral minoxidil, nutritional support, or scalp microneedling, depending on the individual's circumstances and the practitioner's recommendations. The appropriateness of combining treatments will depend on your specific situation, the cause of your hair loss, and any contraindications that may apply. Your practitioner will advise on what combination of approaches — if any — may be most relevant to your individual needs.

Does PRP hair treatment work for all types of hair loss?

PRP is generally considered most relevant for certain types of hair loss, particularly androgenetic alopecia (pattern hair loss) and some cases of telogen effluvium. It is thought to be less effective in cases of scarring alopecia, where hair follicles have been permanently damaged, or in areas where there has been complete and long-standing follicle loss. The type and cause of your hair loss is a key factor in assessing whether PRP may be appropriate for you, and this will be explored during a thorough consultation.

Preparing for a PRP hair treatment consultation involves far more than simply booking an appointment. The information you bring to that consultation — about your medical history, current medications, lifestyle habits, previous treatments, and expectations — forms the foundation of a safe, personalised, and ethically sound assessment.

Understanding what to disclose before PRP hair treatment empowers you to participate actively in your own care. It enables your practitioner to make a genuinely informed judgement about whether the treatment may be appropriate for your individual circumstances, and to give you honest, balanced guidance about what you might realistically expect.

Hair loss is a deeply personal concern, and exploring your options should be a process that feels supportive, informative, and free from pressure. Whether PRP hair treatment proves to be the right pathway for you or not, a thorough consultation with a qualified practitioner is always the appropriate first step.

Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation.

If you would like to explore your options, we encourage you to reach out to a qualified practitioner who can provide a personalised assessment and guide you through an informed decision-making process.
