PRP injections for hair loss are a promising, minimally invasive treatment option for individuals looking to restore thinning hair and improve scalp health.
By using the body’s own platelets to stimulate hair follicles, PRP therapy offers a natural approach to supporting hair regrowth without surgery or synthetic medications.
As interest in regenerative medicine grows, more patients are turning to PRP as part of a comprehensive strategy to address hair loss.
We’ll walk you through what PRP is, how it works, conditions it can help, and what results you can expect—empowering you to make an informed decision about whether this innovative treatment is right for you.
What Are PRP Injections for Hair Loss?
Platelet-rich plasma (PRP) injections for hair loss involve taking a small sample of your blood, processing it to concentrate the platelets, and then injecting this platelet-rich plasma into areas of the scalp affected by hair thinning or loss.
Platelets play a major role in healing and tissue regeneration. The concentrated PRP can stimulate hair follicles, improve blood supply, and promote the growth of thicker, healthier hair.
When injected into the scalp, PRP releases growth factors such as platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and transforming growth factor (TGF), which signal hair follicles to enter the active growth phase (anagen).
PRP may also increase blood supply and nutrient delivery to hair follicles and prolong the survival of dermal papilla cells, which support hair shaft development.
The result is often an improvement in hair density, thickness, and overall scalp health, especially in patients with early-stage hair loss or androgenetic alopecia.
Conditions PRP Injections Can Treat
PRP injections are most commonly used to treat androgenetic alopecia, also known as male or female pattern baldness. This hereditary condition, driven by genetic and hormonal factors, causes hair follicles to shrink and produce thinner, shorter hair strands over time.
PRP can help counteract this process by stimulating follicles and promoting the growth of thicker, healthier hair.
In addition to androgenetic alopecia, PRP injections may also be beneficial for other types of hair loss and circumstances, such as:
- Telogen effluvium: A temporary form of hair loss triggered by stress, hormonal changes, or nutritional deficiencies
- Alopecia areata: An autoimmune condition that causes patchy hair loss
- Traction alopecia: Hair loss caused by tight hairstyles or excessive styling practices
- Lichen planopilaris: PRP is not typically a first-line treatment for scarring alopecias, but some providers may use it to support scalp healing.
- Supporting hair transplantation: When PRP is used in combination with hair restoration surgery, patients can experience a 15% greater hair yield.
While PRP injections can be effective for various types of hair loss, it's essential to consult with a qualified dermatologist to determine if this treatment is right for your specific condition and goals.
Who Is a Good Candidate for PRP Injections for Hair Loss?
PRP injections can be an excellent option for many people experiencing hair loss, but not everyone is an ideal candidate. Understanding the factors that influence candidacy can help you determine if this treatment is right for you.
Types of Hair Loss That Respond to PRP
PRP injections are most effective for individuals with early to moderate stages of androgenetic alopecia.
If you've noticed gradual hair thinning, a receding hairline, or a widening part, you may be a good candidate for PRP. This treatment works best when hair follicles are still active and capable of producing new hair growth.
PRP may also be beneficial for people with other types of hair loss, such as telogen effluvium or alopecia areata, particularly when used in combination with other treatments such as topical medications or low-level laser therapy (LLLT).
Factors That Affect Candidacy
Several factors can influence whether PRP injections are a suitable treatment option for you:
- Age: PRP tends to be more effective in younger patients with early-stage hair loss, as their hair follicles are more responsive to growth factors.
- Overall health: Patients should be in good general health and free from any underlying conditions that could impair healing or hair growth.
- Medications: Certain medications, such as blood thinners or immunosuppressants, may affect eligibility for PRP injections.
It's important to have realistic expectations about the results of PRP injections. While this treatment can improve hair thickness and density in some people, it may not restore hair to its original fullness.

How Effective Are PRP Injections for Hair Loss?
PRP injections can be an effective option for many individuals experiencing hair thinning or early-stage hair loss. Success often depends on factors such as the underlying cause of hair loss, how advanced it is, and the individual’s overall health.
Those with active, functioning hair follicles generally respond best. While many patients see noticeable improvements in hair density and thickness, PRP is not guaranteed to work for everyone and is less effective for advanced baldness or scarring alopecia.
Results You Can Expect
Patients who respond well to PRP can typically expect to see reduced hair shedding within the first month and visible improvements in hair thickness and growth by three to six months. The hair may look fuller and healthier overall.
Results continue to build with additional sessions, and maintenance treatments are usually recommended to preserve progress. However, the extent of improvement varies by individual and is influenced by consistency and treatment timing.
It's important to remember that PRP injections are not a cure for hair loss—they help manage the condition and promote healthier hair growth.
What Clinical Studies Show
Many clinical studies have demonstrated the efficacy of PRP injections for hair loss, but more research is needed, and standardization needs to be made for procedural practices.
- In 2022, 15 studies performed between 2018 and 2021 were reviewed in detail. The findings demonstrated that PRP treatment is highly effective in treating AGA and that it can work faster and more effectively than topical minoxidil and oral finasteride.
- A 2017 meta-analysis in the Journal of Cosmetic Dermatology concluded that PRP injections were a safe and effective treatment for androgenetic alopecia, resulting in significant improvements in hair count and density.
- According to an article published in the International Journal of Molecular Sciences, a 2020 review of studies found that in 84% of studies displayed a positive effect of PRP for AGA treatment and that PRP can be considered a safe and effective alternative procedure to treat hair loss compared with minoxidil, finasteride, and dutasteride.
These studies highlight the potential of PRP injections as a valuable tool in the fight against hair loss, particularly when used in conjunction with other evidence-based treatments such as Happy Head's custom topical solutions.
Side Effects of PRP Injections for Hair Loss
PRP injections are generally well-tolerated because the treatment uses your own blood, which minimizes the risk of allergic reactions.
Common side effects are typically mild and short-lived, including scalp tenderness, swelling, redness, or slight bruising at injection sites. Some patients may experience a tingling or itching sensation as the scalp heals.
Less commonly, a temporary headache or mild discomfort during the procedure may occur.
Rare side effects include infection at the injection site, injury to blood vessels or nerves, and formation of scar tissue.
Since no foreign substances are introduced, systemic side effects are extremely rare. Proper technique and post-procedure care significantly reduce risks.
Patients with certain medical conditions or scalp infections may be at higher risk for complications and should be evaluated carefully before treatment.
Who Should Avoid PRP Injections?
While PRP injections are generally safe for most people, there are some individuals who should avoid this treatment:
- Those with active infections or skin diseases in the treatment area.
- People with bleeding disorders or those taking blood-thinning medications.
- Individuals with a history of keloid scarring.
- People with anemia, thyroid disorders, or certain types of cancer.
- Pregnant or breastfeeding women.
- Those who smoke heavily.
Discuss your medical history and any medications you're taking with your dermatologist before undergoing PRP injections to ensure the treatment is safe and appropriate for you.
Cost and Considerations for PRP Injections for Hair Loss
When considering PRP injections for hair loss, it's important to factor in the cost and understand the need for long-term commitment.
Average Prices per Session
The cost of PRP injections for hair loss can vary depending on factors such as geographic location, provider experience, and the number of sessions required.
On average, a single PRP treatment session can range from $400 to $1,500, with most patients needing three to six sessions for optimal results.
While the upfront cost of PRP injections may seem high, it's important to consider the potential long-term benefits of improved hair growth and the boost in self-confidence that comes with treatment.
Insurance Coverage and Payment Options
Most insurance plans do not cover PRP injections for hair loss, as they are considered a cosmetic procedure. However, some providers may offer financing options or payment plans to help make the treatment more accessible.
Long-Term Commitment
PRP for hair loss is not a one-time solution. Initial treatment typically involves multiple sessions spaced weeks apart, followed by maintenance treatments every 6 to 12 months to sustain results.
Because hair growth is a gradual process and hair loss can be ongoing, long-term commitment is necessary to preserve improvements and prevent regression over time.
PRP Injections for Hair Loss: Step-by-Step Process
Understanding what to expect during the PRP injection process can help you feel more comfortable and prepared for your treatment.
- Blood draw: A small sample of blood is taken from your arm and placed in a specialized tube.
- Centrifugation: The blood sample is processed in a centrifuge to separate the platelet-rich plasma from other blood components.
- PRP preparation: The concentrated PRP is drawn into a syringe, ready for injection.
- Scalp preparation: The treatment area is cleaned, and a topical numbing cream may be applied for comfort.
- PRP injection: The provider uses a fine needle to inject PRP into multiple sites across the scalp, focusing on areas of hair thinning or loss.
- Post-treatment care: You'll receive instructions for caring for your scalp after the procedure, which may include avoiding strenuous activity and direct sun exposure for a short period.
How Many Sessions Are Needed?
The number of PRP sessions required for optimal results varies depending on the individual and the extent of their hair loss. Most patients undergo a series of three to six treatments, spaced four to six weeks apart, to stimulate hair growth and improve hair density.
After the initial series of treatments, maintenance sessions are typically recommended every six to 12 months to sustain results and prevent further hair loss.
Scalp Care Before and After PRP Injections
Proper preparation and aftercare are essential for maximizing the benefits of PRP injections and minimizing the risk of complications.
Before your PRP treatment:
- Avoid blood-thinning medications, such as aspirin or ibuprofen, for at least a week before the procedure.
- Refrain from smoking and excessive alcohol consumption, as these can impair healing.
- Drink plenty of water to stay hydrated.
- Wash your hair and scalp thoroughly on the morning of your scheduled procedure, and avoid the use of styling products.
- Inform your provider of any medications or supplements you're taking.
After your PRP injections:
- Avoid washing your hair for at least 12 hours post-treatment.
- Refrain from using harsh hair products or heat styling tools for 48 hours.
- Protect your scalp from direct sun exposure, and wear a hat when outdoors.
- Gently massage your scalp to promote circulation and distribute the PRP evenly.
- Follow any additional instructions provided by your dermatologist.
Alternative and Complementary Treatments
While PRP injections can be a powerful tool in the fight against hair loss, they are often most effective when combined with other evidence-based treatments.
Some alternative and complementary treatments to consider include:
- Topical and oral medications: Minoxidil and finasteride are proven, effective treatments that can help slow hair loss and promote new hair growth.
- Low-level laser therapy (LLLT): This noninvasive treatment uses low-level light to stimulate hair follicles and improve hair thickness and density.
- Nutritional supplements: Certain vitamins and minerals, such as biotin, vitamin D, and iron, can support healthy hair growth when taken in appropriate doses.
- Scalp microneedling: Microneedling, or dermarolling, is a minimally invasive treatment that creates tiny channels in the scalp to stimulate collagen production and enhance the absorption of topical hair growth products.
New treatments are continually emerging, such as Happy Head’s Hair Serum, a lightweight formula containing biomimetic actives such as Procapil®, Capixyl®, and Redensyl® as well as powerful botanicals including saw palmetto, seabuckthorn, rosemary oil, and collagen.
PRP Injections for Hair Loss - Are They Right for You?
Deciding whether PRP is the right approach for your hair loss starts with understanding your unique condition, goals, and expectations.
While PRP can be an effective and minimally invasive option for many, it’s not a universal solution. The best outcomes are typically seen in those with early-stage thinning and active hair follicles.
A dermatologist can assess the cause and severity of your hair loss, review your medical history, and determine if PRP aligns with your needs or if another treatment may be more suitable. Personalized care is essential for achieving meaningful and lasting results.
If you're looking for a non-surgical way to stimulate natural hair regrowth, your next step should be a professional consultation to explore the potential of PRP injections for hair loss.
Talk to a board-certified dermatologist to discuss your goals and find the solution that is best for you.
