PRP Hair Therapy: How It Works and What Results to Expect

Platelet-Rich Plasma (PRP) therapy has emerged as one of the most popular and effective non-surgical treatments for hair loss. It uses your body's own healing mechanisms to stimulate dormant hair follicles and promote natural hair regrowth.

What Is PRP?

PRP is a concentrated solution derived from your own blood. Blood contains plasma (the liquid component), red blood cells, white blood cells, and platelets. Platelets are rich in growth factors — proteins that play crucial roles in tissue repair and regeneration.

When PRP is injected into the scalp, these growth factors:

• Stimulate dormant hair follicles to enter the active growth phase
• Increase blood supply to the follicles
• Strengthen existing hair shafts, reducing thinning
• Prolong the growth phase (anagen) of the hair cycle

The PRP Procedure: Step by Step

1. Blood Draw: A small amount of blood (15–20 ml) is drawn from your arm, similar to a routine blood test
2. Centrifugation: The blood is placed in a centrifuge machine that spins it at high speed, separating the components. The platelet-rich layer is isolated
3. Activation: The PRP may be activated with calcium chloride to release growth factors
4. Injection: Using fine needles, the PRP is injected into the scalp at the level of the hair follicles, focusing on areas of thinning
5. Duration: The entire procedure takes about 45–60 minutes

Who Is an Ideal Candidate?

PRP works best for:

• Early to moderate hair loss: When hair follicles are miniaturised but still alive
• Androgenetic alopecia: Both male and female pattern hair loss
• Telogen effluvium: Temporary hair shedding from stress, illness, or nutritional deficiency
• Post-hair transplant: Enhances graft survival and recovery

PRP is not effective for completely bald areas where follicles are no longer present (scarring alopecia).

Treatment Protocol

Phase	Frequency	Sessions
Initial Treatment	Once every 3–4 weeks	4–6 sessions
Maintenance	Once every 3–4 months	Ongoing as needed

What Results Can You Expect?

• 1–2 months: Reduced hair shedding is typically the first noticeable change
• 3–4 months: Early signs of new hair growth; existing hair appears thicker
• 6–9 months: Significant improvement in hair density and coverage
• 12+ months: Maximum results; maintenance sessions help sustain the gains

Results vary based on the degree of hair loss, age, overall health, and consistency with the treatment protocol. PRP works best as part of a comprehensive hair loss management plan that may include medications (minoxidil, finasteride), nutritional supplementation, and lifestyle modifications.

Is PRP Painful?

A topical numbing cream is applied to the scalp before the injections, making the procedure comfortable. Most patients describe it as mild discomfort. There's no downtime — you can return to normal activities immediately, though vigorous exercise should be avoided for 24–48 hours.

Side Effects

Since PRP uses your own blood, allergic reactions are virtually impossible. Common mild effects include:

• Mild scalp soreness for 1–2 days
• Temporary swelling at injection sites
• Minor bruising (rare)
