Platelet Rich Plasma (PRP) Hair Restoration Injections in St. Louis, MO
Hair loss is a common concern that can affect anyone, regardless of gender or age. From hormonal changes to genetics and lifestyle factors, there are multiple reasons why people experience thinning hair or hair loss. If you are looking for a non-surgical, minimally invasive way to help restore your hair’s natural thickness and vitality, Platelet-Rich Plasma (PRP) hair restoration may be an option worth exploring.
What Is Platelet Rich Plasma (PRP) Hair Restoration?
PRP hair restoration is a procedure that uses your body’s own growth factors to stimulate and enhance hair growth. PRP, or Platelet-Rich Plasma, is derived from your own blood and is rich in platelets, growth factors, and specialized proteins. When injected into the scalp, these components may help promote tissue repair, reduce inflammation, and potentially awaken dormant hair follicles to encourage healthier, thicker hair growth.
How Is the Process Done?
- Blood Draw - The first step involves taking a small sample of your blood—usually a small vial from your arm, similar to a routine blood test.
- Centrifugation - The drawn blood is then placed in a centrifuge, a specialized machine that spins the sample at a high speed. This process separates the blood components into layers. The top layer is the platelet-rich plasma, which is what we use for the treatment.
- Preparation of the PRP - After centrifugation, the concentrated platelet-rich plasma is carefully extracted into a syringe, ready for injection.
- Scalp Injection - The PRP is injected into areas of the scalp where thinning or hair loss is most apparent. Typically, multiple injections are administered to ensure even coverage across the target area. Your provider may apply a numbing cream or use other techniques to minimize discomfort. The entire process usually takes about 30–60 minutes, depending on the size of the treated area.
- Repeat Sessions - PRP hair restoration is not a one-time procedure. Typically, multiple sessions spaced about 4–6 weeks apart are recommended. Maintenance treatments may be suggested every 3–6 months, depending on individual response and hair goals.
How Does PRP Work for Hair Growth?
PRP therapy leverages the healing properties of your own blood. Platelets contain a variety of growth factors and proteins that are known to:
- Stimulate Cell Growth: Growth factors can signal cells in hair follicles to enter a more active growth phase.
- Boost Collagen Production: Collagen supports healthy hair follicles and scalp tissue.
- Improve Blood Supply: Enhanced blood flow to the scalp can help follicles receive more nutrients and oxygen, further encouraging hair growth.
By directly injecting these growth factors into areas of hair loss, PRP can potentially “kickstart” dormant or weaker hair follicles, resulting in thicker, healthier hair over time.
What Is PRP Used For?
- Androgenic Alopecia (Male/Female Pattern Baldness): One of the most common forms of hair loss. PRP can help slow down or sometimes reverse the thinning process.
- Hair Thinning: Anyone experiencing generalized hair thinning or patchy loss may benefit.
- Supplement to Hair Transplant Surgery: PRP can also be used to help improve the success of hair transplants, both before and after the procedure.
Who Is a Good Candidate?
PRP hair restoration may be a good option for:
- Individuals in the early stages of hair loss or those experiencing thinning hair.
- People with androgenic alopecia, or pattern baldness, who still have functioning hair follicles.
- Individuals looking for a non-surgical procedure to help slow hair loss or enhance existing hair.
Who Might Not Be an Ideal Candidate?
- Those with severe hair loss or completely inactive follicles (e.g., advanced baldness) might see limited results.
- Anyone with underlying medical conditions (like certain blood disorders, chronic illness, or autoimmune diseases) should consult with a healthcare provider, as PRP might not be advised or might require extra caution.
- People on blood thinners or with platelet dysfunction syndromes could experience less effective results.
Possible Side Effects
Since PRP uses your own blood, the risk of allergic reaction is exceptionally low. However, as with any medical procedure, there are still some potential side effects:
- Mild Pain or Discomfort at the Injection Site: The injections can cause slight stinging or pressure.
- Scalp Tenderness: Some people may feel mild soreness or tightness in the treated areas.
- Redness or Swelling: This typically subsides within a day or two.
- Bruising: A small amount of bruising may occur where injections were made.
- Infection: While rare, any time needles are used, there is a slight risk of infection at the injection site.
Most individuals can return to their normal routine immediately following treatment, but your provider may recommend avoiding strenuous exercise or direct sun exposure to the treated areas for at least 24 hours.
Benefits of PRP Hair Restoration
- Minimally Invasive: No surgery, incisions, or lengthy recovery is required.
- Natural-Looking Results: Because PRP works with your existing follicles, results typically appear natural over time.
- Low Risk of Allergic Reaction: You’re using your own blood components, minimizing rejection risks.
- Short Procedure Time: Appointments usually last under an hour.
- Can Be Combined with Other Treatments: Often used alongside topical or oral hair loss medications, or after hair transplant surgery to boost outcomes.
General Questions
- How many sessions will I need? Most providers recommend an initial series of 3 to 4 treatments, spaced about 4–6 weeks apart. Afterward, maintenance sessions might be needed every few months.
- When will I see results? Hair growth cycles take time. Noticeable improvements typically start to appear in about 3–6 months after the first session, with more significant changes visible at around 6–12 months.
- Is it painful? Most patients report only mild discomfort. A topical numbing agent or local anesthetic is often used to minimize pain. Some compare the sensation to a series of small pinpricks.
- Can I go back to work immediately after PRP? Yes, in most cases. Some people experience mild soreness or redness, but it generally doesn’t prevent returning to your normal routine right away.
- Is PRP safe? PRP is considered very safe because it uses your own blood components. Complications are rare, but as with any procedure involving injections, slight risks of bleeding, infection, or bruising exist.
- How long do the effects last? Results vary, and hair growth maintenance can require ongoing sessions. The benefits can last as long as you continue with the recommended treatment plan.
Additional Tips and Considerations
- Pre-Treatment Preparation: Your provider may suggest you stay well-hydrated, avoid blood thinners (if medically appropriate), and discontinue certain supplements that could increase bleeding risk for at least a week before treatment.
- Post-Treatment Care: Avoid harsh chemical hair treatments, direct sun exposure, or intensive workout on the same day as your PRP session. Follow any post-care instructions from your provider to optimize results.
- Lifestyle Factors: Healthy diet, adequate sleep, and stress management can support overall hair health. Speak to a professional about vitamins or supplements that may help promote hair growth in conjunction with PRP.
PRP hair restoration offers a promising solution for those looking to combat hair thinning or early-stage hair loss without surgery. By using your body’s own growth factors, PRP can potentially rejuvenate hair follicles, leading to thicker, healthier hair over time. While individual results vary, many patients find that PRP is a valuable part of their long-term hair-care strategy.

factors. These growth factors stimulate the body’s repair mechanisms, leading to tissue regeneration and accelerated healing. - Reduced Risk of Allergic Reaction: Because PRP is autologous (from the patient’s own blood), there is minimal risk of adverse or allergic reactions.
- Quick Procedure: A standard PRP treatment can be done in an hour or less (blood draw, centrifugation, and injection/topical
application). - Minimal Recovery: Most patients resume normal activities shortly after treatment, although mild redness, swelling, or soreness may occur.
