Thicker, fuller hair is a cosmetic goal and a boost in confidence that starts at the cellular level. Over-the-counter topical treatments offer only temporary surface-level fixes, but clinical treatments like Platelet-Rich Plasma (PRP) work from the inside out. This restoration process harnesses your body’s biological power to revitalize sleeping follicles and strengthen thinning strands.

What is PRP?

Platelet-Rich Plasma (PRP) is a high-concentration autologous serum derived from your own blood. Your blood contains platelets that are packed with alpha granules, which release essential growth factors, such as Vascular Endothelial Growth Factor (VEGF) and Transforming Growth Factor (TGF).

In the context of hair restoration, PRP acts as a biological fertilizer that delivers concentrated proteins directly to the root of the hair follicle to stimulate repair and regeneration.

At Lumiskins, our medical team uses advanced PRP systems designed for high platelet concentration and precision scalp delivery. Learn more about our clinical process for PRP hair restoration in Toronto.

How Does PRP Hair Treatment Work?

PRP is a medical procedure that uses centrifugal force to isolate regenerative cells. Here are the steps in detail:

    1. Blood Sampling: A small sample of blood (roughly 10ml to 30ml) is collected from the arm.
    2. Separation: The blood is placed in the Eclipse PRP® system. . This system spins at RPM (Revolutions Per Minute) to separate plasma from heavier red and white blood cells.
    3. Enrichment: Resulting plasma contains a platelet count up to 5–10 times higher than normal blood.
    4. The Administration: The enriched plasma is then injected into the scalp at the subdermal level, where the hair follicles reside, using a fine-gauge needle or a delivery device.

How Many PRP Sessions are Needed for Hair?

Consistency is the foundation of success with regenerative medicine. Hair growth cycles are slow, so treatment is structured in phases to match your biology.

Phase What Happens Typical Schedule Purpose
Initial Phase Series of sessions deliver concentrated growth factors to stimulate inactive follicles. 3–4 sessions
Every 4–6 weeks		 Jumpstarts follicles and begins regeneration.
Maintenance Phase Periodic treatments maintain results and address ongoing genetic thinning. Every 6–12 months Preserves density and supports long-term results.
Results (2–3 Months) Hair shedding noticeably decreases as follicles stabilize. Early response period Indicates treatment is working internally.
Results (4–6 Months) Visible thickness, density, and new hair growth appear. First full growth cycle Shows measurable cosmetic improvement.

What is the Success Rate of PRP?

In a clinical setting, success is defined by two primary metrics: a measurable increase in hair count per square centimeter and a visible increase in hair shaft diameter. According to the NIH’s clinical report, PRP results in 68% hair growth, 45% increase in hair thickness, and 54% improvement in hair quality.

Above all, the success of PRP also depends on platelet concentration. Systems like the Eclipse PRP® promise a high platelet yield, which is directly linked to better clinical outcomes. Moreover, the treatment uses your own biology, hence younger patients or those with high-nutrient diets (rich in Iron and Vitamin D) often see faster results.

Does PRP Regrow Hair?

PRP is highly effective at regrowing hair in follicles that have become lazy or miniaturized. It re-energizes the follicle by signaling the cells to enter the Anagen (growth) phase.
Note: While PRP reverses early-stage thinning, it cannot create new follicles on a completely bald scalp. For those with advanced hair loss, it is important to understand the differences between PRP vs. Transplants to choose the smarter solution for your specific needs.

Will My Hair Thicken After PRP?

Yes, hair thickening is often the most noticeable result of the treatment. Many people suffer from miniaturization, a process in which hair follicles shrink over time, producing progressively thinner, shorter, and more brittle strands.

PRP reverses hair growth by increasing the blood supply to the follicle and improving the health of the hair bulb. It also increases the hair shaft diameter, making your overall head of hair appear much denser and more voluminous.

How Long Does PRP Last?

PRP usually lasts 12 to 18 months with proper maintenance. Hair loss is often the result of continuous exposure to Dihydrotestosterone (DHT), so if this exposure is not maintained, the benefits of PRP will eventually fade.

What to Avoid After PRP Hair Treatment?

Follow these post-treatment guidelines to achieve the best results:

  • Do not wash your hair for at least 24 hours to allow the injection sites to close.
  • Avoid heavy exercise or activities that cause excessive sweating for 48 hours.
  • Avoid saunas, steam rooms, and hair coloring for at least 3 days.

What Are the Side Effects of PRP?

PRP is autologous (sourced from your own body), hence the risks of systemic side effects, allergic reactions, or rejection are non-existent. However, the physical process of injection can cause temporary reactions, e.g.:

  • Scalp Tenderness: A mild soreness that usually resolves within 24 hours.
  • Tightness: A feeling of pressure or fullness in the scalp immediately after the injections.
  • Minor Swelling: In some cases, slight swelling can occur near the forehead or at the injection site; it usually resolves within 48 hours.

What Are the Disadvantages of PRP?

The limitations or disadvantages of PRP treatment include:

  • Time Commitment: It requires multiple visits to achieve a cumulative effect.
  • Biology-Dependent: Your results are only as good as the quality of your own blood. Patients with low platelet counts or certain chronic illnesses may have fewer results.
  • Patience Required: It relies on the natural hair growth cycle,ycle so visible changes often show up in 3 to 6 months.

Is PRP Better Than Minoxidil?

PRP is often considered better for patients seeking a natural, high-potency treatment without the burden of daily maintenance. The two options are not mutually exclusive. Using PRP to rebuild the follicle’s internal health while using Minoxidil to maintain surface-level blood flow is a common clinical strategy for achievingmaximum density.

Feature PRP (Platelet-Rich Plasma) Minoxidil (Topical)
Primary Mechanism Regenerative: Uses growth factors to repair and rebuild the follicle itself. Vasodilator: Widens blood vessels to increase blood flow while the drug is present.
Application Periodic clinical sessions (usually every 4–6 weeks initially). Daily application (once or twice every single day) for life.
Delintoery Method Injected directly to the subdermal level at the hair bulb. Applied topically to the surface of the scalp.
Potency High concentration of 100% natural signaling proteins. Synthetic chemical compound.
Compliance No daily routine to remember. Low patients frequently forget or dislike the greasy texture.
Side Effects Temporary local swelling or tenderness. Possible scalp irritation, dryness, or unwanted facial hair growth.

Does PRP Worsen Hair Loss?

PRP does not worsen permanent hair loss, however, it can cause a temporary physiological shift that may look concerning to the untrained eye. The treatment restarts your hair’s natural growth clock. The follicles must first push out the old, weak, and thin hairs to make space for new, thicker hair to grow in.

Why is My Hair Loss So Much After PRP?

It can be alarming to see shedding shortly after your first session, but this is a clinical phenomenon known as “Shock Shedding” or Exogen. The sudden influx of growth factors pushes follicles from the Telogen (resting) phase into the Anagen (growth) phase. For the new, thicker hair to grow out, the old, weak, and thin hair must be shed first. It is a positive sign that the treatment is successfully resetting your hair growth cycle.

Final Words

Platelet-Rich Plasma therapy represents a shift from masking hair loss to actively repairing the biological foundations of hair growth. PRP provides a safe, natural, and clinically proven path to achieving sustainable hair density and thickness by utilizing your body’s own healing mechanisms. While the journey requires patience and a commitment to maintenance, the ability to wake up your own follicles offers a long-term solution that topical chemicals cannot match. If you are ready to move beyond surface-level fixes and invest in your hair’s health from the inside out, PRP is the definitive next step.
