Choosing between a 3-session and a 6-session protocol for Platelet-Rich Plasma injection in riyadh(حقن البلازما للشعر في الرياض) (PRP) therapy often feels like a gamble, but it’s actually a matter of matching the "dose" to the degree of hair thinning.

Here is a breakdown to help you decide which path aligns with your goals.

🏗️ The Core Difference

PRP works by using your own platelets to stimulate dormant follicles. Think of it like a garden: some lawns just need a seasonal fertilizer (3 sessions), while others need a complete soil overhaul (6 sessions).

🟢 When 3 Sessions is Enough

If you are catching hair loss in its infancy, three sessions is the industry standard for a "loading dose."

• Preventative Care: You have a family history of hair loss but haven't seen significant scalp exposure yet.

• Quality Boost: Your hair feels "limp" or "tired," and you want to increase the diameter of individual hair shafts.

• Post-Transplant: Many surgeons recommend a short 3-session burst to help newly transplanted grafts "take" and heal faster.

🔴 When 6 Sessions is Better

If you’ve been noticing "miniaturization" (hairs becoming thinner and shorter) for over a year, three sessions might leave you underwhelmed.

• Advanced Thinning: If you can easily see your scalp under bright lights, you likely need the cumulative growth factors of a longer cycle.

• Chronic Telogen Effluvium: For those recovering from significant stress or illness-related shedding, more sessions help "reset" the growth cycle.

• The "Slow Responder": Some individuals have lower baseline platelet counts; doubling the sessions ensures the scalp receives an adequate biological signal to restart growth.

💡 Factors That Outweigh Session Count

The number of sessions matters, but the quality of the plasma is the real kicker. Even 10 sessions won't help if the protocol is weak.

1. Concentration Levels: Ensure your provider is using a double-spin centrifuge. You want a concentration that is at least $5\times$ to $7\times$ your baseline platelet levels.

2. Depth of Delivery: The plasma must reach the bulb of the follicle, typically 4mm to 6mm deep.

3. The "Booster" Effect: Many modern protocols combine PRP with Microneedling or Exosomes to create a synergistic effect.

Is it worth the jump?

Going from 3 to 6 sessions is a commitment of both time and money. If you're unsure, most dermatologists suggest starting with 3 sessions and evaluating your progress at the 4-month mark. Because hair grows in cycles, you won't see the full "win" of those sessions immediately anyway.
