What Happens During a PRP Hair Treatment Appointment? Step-by-Step Guide

Hair thinning and hair loss are concerns that affect a significant number of people across different ages and backgrounds. Whether it is gradual thinning at the temples, diffuse shedding across the scalp, or more noticeable changes in hair density, these experiences can understandably prompt many individuals to research their options. One treatment that has attracted considerable interest in recent years is PRP hair treatment — a procedure that uses the body's own growth factors to support scalp health and hair follicle activity.

Many prospective patients find themselves wondering what a PRP hair treatment appointment actually involves. What happens when you arrive at the clinic? Is the process uncomfortable? How long does it take? These are entirely reasonable questions, and understanding the process in advance can help you feel more informed and at ease before attending a consultation.

This article provides a clear, step-by-step guide to a typical PRP hair treatment appointment — covering preparation, the procedure itself, and aftercare considerations — while acknowledging that individual suitability should always be assessed by a qualified practitioner.

A PRP hair treatment appointment typically involves a blood draw, centrifugation to concentrate platelet-rich plasma, and careful injection of that plasma into areas of the scalp. The process generally takes between 60 and 90 minutes. Individual suitability and expected outcomes depend on personal assessment by a qualified healthcare professional.

Platelet-Rich Plasma (PRP) therapy is a procedure that uses components derived from your own blood to deliver concentrated growth factors directly to the scalp. The fundamental premise is that platelets — small blood cells involved in healing and tissue regeneration — contain a range of growth factors that may support the environment around hair follicles.

PRP is not a new concept in medicine. It has been used for many years in orthopaedic, dental, and wound-healing settings before finding application in aesthetic and hair restoration contexts. In hair treatment, the aim is generally to support the scalp environment and, where relevant, to encourage follicle activity in areas experiencing thinning.

It is important to note that PRP is considered a supportive treatment rather than a cure for hair loss. Its appropriateness depends on the underlying cause of hair thinning, the individual's health history, and other clinical factors. A thorough consultation with a qualified practitioner is essential before proceeding, and the PRP treatment overview can help explain the clinical pathway.

Understanding why PRP may be relevant to hair health begins with the biology of hair follicles. Each follicle goes through a natural cycle of growth (anagen), regression (catagen), and rest (telogen). In certain forms of hair thinning — such as androgenetic alopecia or stress-related shedding — this cycle can become disrupted, with follicles spending longer in the resting phase and producing progressively finer hair.

Platelets within the blood contain a range of bioactive proteins, including vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and insulin-like growth factor (IGF). When concentrated and delivered directly to the scalp, these proteins may interact with the follicular micro-environment — potentially supporting tissue repair processes, improving localised blood supply, and creating conditions that are more conducive to follicle activity.

It is worth emphasising that while the biological rationale for PRP in hair treatment is scientifically plausible and supported by a growing body of clinical research, individual responses vary. Results are not guaranteed, and the treatment is not appropriate for all types or stages of hair loss. A practitioner-led assessment remains the most reliable way to determine whether PRP may be a suitable option for a given individual.

A responsible PRP hair treatment journey begins well before the procedure itself. At a reputable clinic, patients will typically attend an initial consultation during which their hair loss history, scalp condition, general health, and treatment goals are discussed in detail.

During this consultation, your practitioner may:

• Review your medical history to identify any contraindications, such as blood clotting disorders, certain medications (including blood thinners), active scalp infections, or other conditions that may affect suitability.
• Assess your scalp and hair loss pattern to determine whether PRP is likely to be a clinically appropriate option.
• Discuss realistic expectations, including how many sessions may be recommended and what the treatment can and cannot achieve.
• Answer your questions about the procedure, recovery, and any associated risks.

On the day of your appointment, patients are generally advised to arrive with a clean scalp, to stay well-hydrated, and to have eaten a light meal beforehand (which can reduce the likelihood of feeling lightheaded during the blood draw). Your practitioner will provide specific pre-appointment guidance tailored to your circumstances.

Step 1 — Arrival and Pre-Treatment Checks

When you arrive at the clinic, a member of the clinical team will confirm your identity, review your consent documentation, and carry out any pre-treatment checks. This is an opportunity to raise any last-minute questions or concerns before proceeding.

A topical numbing cream may be applied to the scalp at this stage, allowing sufficient time to take effect before the injections begin. This step varies by clinic and practitioner preference, and your comfort will be a key priority throughout.

Step 2 — The Blood Draw

A small volume of blood — typically between 15 and 60 millilitres, depending on the treatment protocol — is drawn from a vein in your arm using a standard venepuncture technique. This is broadly similar to a routine blood test. Most patients find this aspect of the procedure straightforward, though it is worth letting your practitioner know if you have any concerns about needles or blood draws in advance.

The blood is collected into specialised tubes that often contain an anticoagulant to prevent premature clotting.

Step 3 — Centrifugation

The collected blood sample is placed into a centrifuge — a machine that spins at high speed to separate the blood into its component layers. This process typically takes between eight and fifteen minutes, depending on the centrifuge protocol used.

The spinning action separates the blood into:

• Red blood cells (the heaviest layer, which sinks to the bottom)
• Platelet-poor plasma (the upper layer)
• Platelet-rich plasma (the concentrated middle layer — the component of interest for hair treatment)

The resulting PRP contains a significantly higher concentration of platelets than would be found in whole blood. Practitioners may use different centrifugation protocols, and the specific concentration achieved can vary between systems.

Step 4 — Preparation of the PRP

Once centrifugation is complete, the practitioner carefully extracts the platelet-rich plasma layer using a syringe. Depending on the protocol, an activating agent — such as calcium chloride — may be added at this stage to stimulate the release of growth factors from the platelets before injection.

The prepared PRP is then drawn up into syringes ready for administration to the scalp.

Step 5 — Scalp Injections

This is the treatment phase of the appointment. Using fine needles, the practitioner carefully administers the PRP across the areas of the scalp identified during assessment as most relevant to the individual's hair loss pattern.

Injections are typically delivered using a systematic technique — sometimes a series of small, shallow injections distributed across the scalp, sometimes a threading or micro-needling approach, depending on the protocol and equipment used.

The level of discomfort experienced varies between individuals. The topical numbing cream applied earlier can help reduce sensitivity, and practitioners are experienced in minimising discomfort throughout this stage. Most patients describe the sensation as mild to moderate pressure or a light stinging feeling rather than significant pain. The injection phase generally takes between 20 and 40 minutes.

Step 6 — Post-Treatment Assessment and Aftercare Guidance

Once the injections are complete, your practitioner will assess the treated area and provide tailored aftercare instructions. This is an important part of the appointment, as following aftercare guidance appropriately can support your recovery and help you understand what to expect in the days and weeks that follow.

Patients are typically able to leave the clinic shortly after the procedure. A follow-up appointment is often scheduled to monitor progress and discuss whether further sessions may be recommended.

In the hours and days following a PRP hair treatment appointment, it is common to experience some mild scalp tenderness, redness, or a sensation of tightness in the treated area. Minor swelling at the injection sites is also possible. These responses are generally short-lived and tend to resolve within a few days.

Most patients are able to return to their normal daily activities within 24 to 48 hours, though specific aftercare guidance — such as avoiding vigorous exercise, swimming, or the application of certain hair products for a defined period — will be provided by your practitioner.

It is worth noting that any observable changes in hair quality or density following PRP treatment typically develop gradually over a period of weeks to months, as the biological processes involved unfold over time. Patients are encouraged to maintain realistic expectations and to attend any scheduled follow-up appointments to allow for proper monitoring.

As with any aesthetic or medical procedure, it is important to approach PRP hair treatment with an accurate understanding of what it may and may not achieve.

Potential benefits associated with PRP hair treatment include support for scalp health, the possibility of improved hair density or texture in appropriately selected individuals, and the fact that the treatment uses the patient's own biological material, which may reduce certain risks associated with foreign substances.

Limitations include the fact that results are variable and not guaranteed. PRP is generally considered more appropriate for individuals in the earlier stages of hair thinning rather than those with advanced hair loss or significant follicle loss. Multiple sessions are typically recommended, and maintenance treatments may be needed over time. The treatment may not be suitable for individuals with certain health conditions.

Factors that may influence outcomes include the underlying cause and pattern of hair loss, individual biological response, the PRP preparation protocol used, overall health and lifestyle, and adherence to aftercare recommendations.

A professional consultation can be a valuable step for anyone experiencing changes in hair density, thickness, or overall scalp health — regardless of whether they ultimately proceed with any particular treatment.

Individuals who may find a consultation particularly helpful include those noticing:

• Gradual thinning across the scalp or at the hairline
• Increased shedding that appears persistent over time
• A reduction in hair density that is affecting confidence or wellbeing
• Questions about whether their hair loss is amenable to non-surgical approaches

A consultation offers the opportunity to understand the likely cause of hair loss, discuss the evidence base for available treatments, and receive personalised guidance from a qualified professional. It does not commit anyone to a specific course of treatment.

For those interested in exploring scalp and skin health as part of a broader aesthetic plan, a consultation at Pantaleo Clinic can provide a comprehensive starting point for understanding your options.

One of the most common questions patients ask is how many sessions they are likely to need. The honest answer is that this varies between individuals and depends on the nature and extent of hair loss, the individual's response to treatment, and the clinical protocol used by the practitioner.

As a general indication, many protocols suggest an initial course of three to four sessions, spaced approximately four to six weeks apart, followed by a reassessment period. Maintenance sessions — typically less frequent — may then be recommended depending on the individual's response and ongoing goals.

It is important to approach this aspect of treatment planning with flexibility and realistic expectations. Progress is gradual, and assessments at follow-up appointments allow the practitioner to make informed recommendations based on observed response rather than a fixed schedule. For a deeper breakdown of timelines and expectations, see how many PRP sessions are usually needed.

Those considering complementary approaches to scalp and hair health may also wish to discuss polynucleotide and regenerative skin-quality approaches, which are being increasingly explored in skin and tissue regeneration contexts.

Good aftercare following a PRP hair treatment session supports both the recovery process and the overall effectiveness of the treatment. General guidance that practitioners commonly recommend includes:

• Avoid washing the scalp for at least 24 hours after treatment, or as advised by your practitioner.
• Avoid vigorous exercise, saunas, and swimming pools for 48 hours to reduce the risk of infection and irritation at the injection sites.
• Do not apply hair dyes, chemical treatments, or styling products containing harsh ingredients for the period specified by your practitioner.
• Stay well-hydrated and maintain a balanced diet, as overall health contributes to hair follicle function.
• Protect the scalp from excessive sun exposure, particularly in the days immediately following treatment.
• Attend scheduled follow-up appointments to allow your practitioner to monitor progress and adjust the treatment plan if necessary.

Beyond the immediate aftercare period, supporting scalp and hair health through good nutritional habits, stress management, and an appropriate hair care routine can contribute positively to outcomes over time. Your practitioner can offer personalised advice during your consultation.

PRP hair treatment carries a generally considered favourable safety profile when performed by a qualified practitioner, largely because it uses the patient's own blood. However, as with any procedure involving injections, there are associated risks and considerations that patients should be aware of:

• Injection site reactions such as redness, swelling, bruising, or tenderness are common and usually temporary.
• Infection is a rare but possible risk with any injection-based procedure, which is why treatment should always be carried out in a hygienic clinical environment by a trained professional.
• Lightheadedness or vasovagal response can occur during or after the blood draw in some individuals.
• Variable results — PRP does not produce the same outcome in every individual, and some patients may not observe significant improvement.
• Not suitable for all types of hair loss — the treatment is unlikely to be appropriate for those with scarring alopecia or in cases where follicles are no longer active.

A thorough consultation is the most reliable way to assess individual risk factors and determine whether PRP is a clinically appropriate option. Patients are encouraged to ask their practitioner about risks in the context of their own health history.

For those interested in broader aesthetic treatments for the face and skin alongside hair health concerns, you can book a consultation with the team for a personalised discussion.

• PRP hair treatment uses concentrated platelets derived from your own blood, delivered to the scalp via injections to support the follicular environment.
• A typical appointment involves a blood draw, centrifugation to produce PRP, and a series of scalp injections — generally taking between 60 and 90 minutes in total.
• Results are gradual and variable; PRP is not a guaranteed cure for hair loss and is more likely to be appropriate for individuals in the earlier stages of thinning.
• Multiple sessions are typically recommended, with maintenance treatments potentially needed over time.
• Individual suitability depends on the cause and extent of hair loss, overall health, and other clinical factors — all of which should be assessed during a professional consultation.
• Aftercare guidance from your practitioner should be followed carefully to support recovery and optimise the treatment experience.

Is PRP hair treatment painful?

Most patients report that PRP hair treatment is tolerable rather than significantly painful. A topical numbing cream is usually applied to the scalp before the injection phase to reduce discomfort. During the injections themselves, sensations are commonly described as mild pressure, a light stinging, or temporary sensitivity. Discomfort levels vary between individuals, and your practitioner will work to ensure your comfort throughout the procedure. If you have concerns about pain, it is worth discussing this openly during your consultation.

How soon might I see results from PRP hair treatment?

Results from PRP hair treatment typically develop gradually over a period of several months rather than appearing immediately after a session. Most practitioners advise patients not to assess outcomes before at least three to six months have passed, as the biological processes involved — including changes in the follicular environment — take time to unfold. Individual timelines vary considerably. Progress is usually monitored through follow-up appointments, and photographs taken at intervals can help track changes objectively.

How many PRP hair treatment sessions will I need?

This varies between individuals and depends on the nature, extent, and cause of hair loss, as well as personal response to treatment. Many clinical protocols suggest an initial course of three to four sessions, typically spaced four to six weeks apart, followed by a review period. Ongoing maintenance sessions may be recommended after the initial course. Your practitioner will tailor a treatment plan to your specific circumstances following assessment and will review this plan at follow-up appointments.

Are there people for whom PRP hair treatment is not suitable?

Yes. PRP hair treatment is not appropriate for everyone. Potential contraindications may include blood clotting disorders, certain autoimmune conditions, active infections of the scalp, specific medications (including anticoagulants), and some forms of hair loss — such as scarring alopecia — where follicular activity may be significantly compromised. Pregnancy and breastfeeding may also affect suitability. A thorough medical history review and clinical assessment during consultation are essential to determine individual appropriateness.

What should I avoid after a PRP hair treatment session?

Following a PRP hair treatment session, practitioners typically advise avoiding washing the scalp for at least 24 hours, refraining from vigorous physical exercise and swimming pools for 48 hours, and avoiding chemical hair treatments or harsh styling products for the period specified. Sun protection for the scalp is also generally recommended in the days following treatment. Specific aftercare instructions will be tailored to your individual circumstances by your treating practitioner, and it is important to follow these carefully.

Can PRP hair treatment be combined with other treatments?

In some cases, practitioners may discuss combining PRP with other treatments — such as microneedling of the scalp or specific nutritional support — as part of a broader hair health plan. Any combination approach should be discussed in detail during consultation, with the practitioner considering individual suitability, potential interactions, and the evidence base for combined protocols. PRP is not typically used in isolation as a complete solution to hair loss, and it is often considered as one component within a more comprehensive management strategy.

Understanding what happens during a PRP hair treatment appointment can help prospective patients feel more informed, prepared, and confident when considering their options. From the initial blood draw and centrifugation process to the scalp injection phase and aftercare, each stage of the appointment has a clear purpose rooted in the biology of platelet-rich plasma and its potential role in supporting the scalp environment.

PRP hair treatment represents one of a number of approaches available to individuals experiencing hair thinning or loss, and it is important to approach it with realistic expectations. Results are not guaranteed, individual responses vary, and the treatment is not appropriate for every person or every type of hair loss.

Treatment suitability, risks, and expected outcomes should always be assessed individually during a professional consultation. If you are considering PRP hair treatment or would like to explore your options in more detail, speaking with a qualified and experienced practitioner is the most reliable first step towards making an informed decision.
