What to Expect From the Visit
Platelet-rich plasma (PRP) treatment uses a concentrated portion of your own blood, prepared for injection into areas of scalp thinning. The aim is to support hair follicles, but results vary, and PRP is not a guaranteed solution for hair loss.
A visit generally begins with a discussion of your hair concerns, health history, and treatment options, followed by informed consent. A clinician draws blood and processes it to separate the platelet-rich plasma. The prepared solution is then injected into selected scalp areas. Your provider explains aftercare and what to watch for before you leave.
The details can differ because PRP preparation and injection methods are not standardized. The number and timing of sessions depend on your needs and your clinician’s assessment. On The Spot Dermatology offers personalized dermatology care in Glenview, so treatment planning should reflect your health, hair-loss pattern, and goals. Ask questions about expected benefits, limitations, and alternatives before deciding whether to proceed.
How the PRP Procedure Works
Platelet-rich plasma (PRP) is prepared from a patient’s own blood. Platelets contain growth-factor proteins that help signal processes involved in tissue repair. In hair treatment, the aim is to place a concentrated portion of these platelets near thinning areas of the scalp. The International Society of Hair Restoration Surgery’s overview of PRP describes the treatment and its limitations.
The general sequence is straightforward: a clinician draws a blood sample, processes it in a centrifuge to separate its components and concentrate the platelets, then injects the resulting PRP superficially into selected scalp areas with a fine needle. The process is also summarized in this review of PRP for hair regrowth.
Details differ between practices. The amount of blood collected depends on the preparation system, and centrifuge steps, injection technique, and appointment length can vary. One source describes a visit lasting about 45 minutes to an hour, but that is an estimate, not a standard duration. On The Spot Dermatology in Glenview emphasizes personalized dermatology care, so questions about the planned steps and timing are best discussed during an individual assessment.
There is no universally accepted protocol for preparing or administering PRP. Providers may also recommend a series of sessions after assessing the pattern and cause of hair loss. The appropriate plan, including whether PRP is suitable, should be discussed with a qualified clinician; treatment does not guarantee a particular result.
Who May Be a Candidate
PRP is generally considered for people with early-to-moderate hair thinning, when some follicles remain active but may be producing finer or weaker hair. It is often discussed for pattern hair loss, though suitability depends on the type and cause of hair loss. The International Society of Hair Restoration Surgery’s guidance on PRP describes thinning hair and more recent hair loss as better circumstances for considering treatment.
PRP cannot create new follicles, so it is unlikely to help areas that are completely bald or where follicles are no longer functioning. Sudden or patchy hair loss may have causes that call for a different assessment or treatment, rather than PRP alone. A dermatologist can examine the scalp and consider the pattern and timing of the loss before discussing options. Readers can also review who may be a candidate for PRP.
Health history matters, too. Blood or platelet conditions, active infection at the treatment site, certain illnesses, and some medications may affect whether treatment is appropriate. Do not stop prescribed medication on your own; discuss medications, supplements, and relevant health conditions with a clinician. At otsdermatology.com, personalized dermatology care provides a setting to discuss the cause of thinning, individual health factors, and whether PRP may fit alongside other treatment options.
Comfort During Scalp Injections
For many patients, the blood draw feels similar to routine laboratory work and is over quickly. The scalp injections are more noticeable, but the sensation varies from person to person and may differ across areas of the scalp.
You may feel brief pinches, stinging, or pressure as PRP is injected. The number and placement of injections depend on the treatment approach, so your experience may not match someone else’s. The International Society of Hair Restoration Surgery’s PRP overview describes small injections into the scalp and notes that pain management may be considered.
A provider may use a topical numbing agent or another comfort measure when appropriate, but no single method is used for every patient or protocol. At On The Spot Dermatology, treatment recommendations are personalized, so ask your clinician which options may fit your needs.
Mild tenderness or sensitivity can occur after treatment and is usually temporary. Before your appointment, ask your clinician what sensations and after-effects to expect with your planned treatment, and what to do if discomfort persists.
Preparing for Your Appointment
How should you prepare for PRP hair treatment? Start with the instructions from your treating clinician. Preparation can differ because PRP methods and individual health needs vary. At otsdermatology.com, care is personalized by healthcare providers, so confirm your own instructions rather than relying on a general checklist. You can also prepare for a dermatology appointment by noting questions and relevant health details in advance.
Before treatment, tell your provider about your medical history, allergies, prescription medicines, over-the-counter drugs, supplements, and any recent illness. Mention blood thinners and medicines such as aspirin or anti-inflammatory drugs in particular. Recommendations about these medicines vary by protocol and patient, so do not stop or change prescribed medication unless your clinician tells you to. The International Society of Hair Restoration Surgery’s PRP guidance notes that treatment protocols differ and that medicine-related instructions should be discussed with the practitioner.
Some practices may ask patients to arrive hydrated, wash their hair beforehand, or avoid styling products on treatment day. Ask which steps apply to you, and whether you should eat or avoid alcohol or smoking before the visit. If anything is unclear, contact the practice before your appointment. Do the same if you feel unwell, so your clinician can advise whether to proceed or reschedule.
Recovery and Aftercare
After scalp injections, temporary tenderness, redness, mild swelling, or injection-site pain may occur. These reactions and how long they last vary from person to person. The medical review of PRP for hair regrowth describes temporary discomfort, itching, redness, and swelling among possible effects, while noting that most patients tolerate treatment well (review of PRP for hair regrowth).
Many patients can return to their usual daily activities soon after treatment, but that does not mean every activity is advisable right away. Follow the aftercare plan given by your clinician, since recommendations depend on the treatment and your individual circumstances. At otsdermatology.com, care is provided by dermatology professionals, so ask your treating clinician which instructions apply to your scalp and health history.
What should you avoid after PRP hair treatment, and when can you wash your hair or shower?
There is no single aftercare schedule for every patient. Your provider may ask you to keep your scalp dry for a specified period, then wash gently when permitted. For example, some guidance recommends waiting 24 to 48 hours, then using lukewarm water and mild shampoo with your fingertips rather than scrubbing or scratching. The International Society of Hair Restoration Surgery’s PRP guidance also advises gentle shampooing and delaying strenuous exercise for several days, but your clinician’s instructions should take priority.
Depending on your plan, you may need to avoid vigorous exercise, heavy sweating, swimming, saunas, hot tubs, prolonged sun exposure, or scalp products for an instructed interval. Ask your clinician before taking anti-inflammatory medicines such as ibuprofen or naproxen, because recommendations vary. Do not stop or change prescribed medication without medical advice.
Possible Benefits and Limitations
PRP may reduce shedding or make hair look thicker for some people with pattern hair loss. Changes can reflect increased hair density, thicker individual strands, or both, but not everyone responds, and improvement is not guaranteed. The International Society of Hair Restoration Surgery’s overview of PRP notes that published findings are mixed.
How well PRP works, and how long any benefit lasts, remain difficult to predict. Hair loss may continue, and maintenance treatments may be discussed, but there is no firmly established schedule or duration of benefit. A dermatologist can assess the cause of thinning and consider whether PRP, alone or alongside other treatments, fits a patient’s needs. At On The Spot Dermatology, treatment decisions can be grounded in personalized dermatologic care rather than a promised outcome.
Researchers do not fully understand how PRP affects hair growth. Preparation methods, platelet levels, injection protocols, and patient characteristics vary across studies and practices, which may help explain inconsistent results. PRP for hair growth is also an off-label use and is not FDA-cleared for this indication, as the ISHRS explains.
PRP is generally well tolerated, though injections can cause temporary scalp pain or tenderness, redness, swelling, bruising, or minor bleeding. Infection or injury to nearby tissue is possible with any injection, while careful sterile technique helps reduce risk. PRP is unlikely to restore hair where follicles are no longer active, and results take time. A clinician can review potential risks and limitations before treatment.
Treatment Schedules and Maintenance
A commonly described starting course is three PRP sessions spaced about a month apart. Some treatment plans then include booster sessions, but there is no universally accepted schedule. Published guidance and research describe different intervals, reflecting variation in preparation methods and treatment protocols.
The International Society of Hair Restoration Surgery’s PRP guidance describes a common three-session monthly course followed by boosters, while a review of PRP for hair regrowth notes that session numbers and spacing vary across studies. Your clinician can tailor timing to your hair-loss pattern, response, and the protocol being used. At On The Spot Dermatology in Glenview, care is personalized, so follow-up can help assess progress and guide next steps.
How many PRP sessions are typically recommended for hair growth, including after a hair transplant?
Three sessions about a month apart are often described as an initial course, with maintenance sometimes recommended afterward. PRP may also be offered as an add-on after hair transplantation, but the available evidence does not establish one accepted number or timing of post-transplant sessions. Your dermatologist or transplant surgeon can advise when it is appropriate in light of the procedure and recovery. PRP does not address every cause of hair loss, and results vary.
How can you support and maintain results after PRP hair treatment?
Keep follow-up appointments so your clinician can review changes and adjust the plan. If advised, continue other appropriate hair-loss treatments alongside PRP rather than assuming injections are a stand-alone solution. Follow your provider’s hair-care instructions, and discuss medications or supplements before starting them. Ongoing treatment may be needed to maintain improvement.
For more on how session spacing can vary, see this guide to PRP treatment sessions and maintenance.
Understanding the Treatment Cost
How much does PRP hair treatment cost, and what affects the total cost? The International Society of Hair Restoration Surgery’s estimate places treatment at about $400 to $1,500 or more per session in the United States. This is a broad range, not a quote, and local prices can differ.
The total depends on factors such as the preparation equipment, any additives, the provider’s experience, and the treatment plan. Since PRP often involves an initial series and may include maintenance sessions, the cost of care can exceed the price of one appointment.
At On The Spot Dermatology in Glenview, a consultation with a healthcare provider can help clarify whether PRP is appropriate and what options fit your needs. Ask for an estimate covering the full recommended course, including possible maintenance, rather than relying only on the first-session price. Individualized planning can also help you compare costs with other hair-loss approaches without assuming that every option suits every patient.
For background on how session frequency may shape planning, see PRP treatment sessions and costs.
Make the Plan Personal
A PRP appointment generally involves drawing blood, processing it to concentrate platelets, then injecting the preparation into selected scalp areas. Details such as preparation methods, injection technique, and aftercare can differ between practices, so ask what your proposed treatment includes. The International Society of Hair Restoration Surgery’s PRP guidance explains that protocols are not standardized.
Before deciding, discuss the cause of your hair loss, whether PRP may suit you, possible risks, alternatives, cost, and realistic expectations with a qualified dermatologist. At otsdermatology.com, personalized care from dermatology providers can help frame that conversation around your individual concerns.
Do not change prescribed medications or set treatment and maintenance timing on your own. Share your health history and current medicines with the treating clinician, then agree on a plan and follow the specific instructions provided.
