Stem Cell DHI is Este Leon's highest-tier protocol — a combination of PRP (Platelet-Rich Plasma) stem cell therapy with Pen DHI implantation. It is designed for patients who want to maximise graft survival, accelerate recovery, and achieve the highest possible density from their procedure.
This article explains the science clearly: what stem cells and PRP actually are in this context, why they improve results, and who benefits most from the upgraded protocol.
What "stem cell hair transplant" means at Este Leon: It refers to PRP (Platelet-Rich Plasma) enriched with growth factors derived from your own blood, applied to grafts during implantation and to the scalp post-procedure. It enhances graft survival, reduces shock loss, and accelerates healing — not a separate surgical technique, but a significant enhancement to DHI.
The Science: What Is PRP?
Platelets are the components of your blood responsible for clotting and healing. They contain growth factors — proteins that signal cells to regenerate, multiply, and repair tissue. When concentrated into Platelet-Rich Plasma (PRP), these growth factors are present at 3–8× their normal blood concentration.
Applied to hair follicles during and after a transplant, PRP growth factors have been shown to:
- Increase follicle viability (graft survival rate) by stimulating cellular energy
- Accelerate healing in both donor and recipient areas
- Reduce inflammation and shock loss severity
- Stimulate surrounding native hair follicles — potentially improving density beyond just the transplanted area
- Shorten the dormant phase, leading to earlier visible growth
The Este Leon Stem Cell DHI Protocol
Blood Draw
A small blood sample is taken from the patient on the day of the procedure — approximately 30–60ml.
PRP Preparation
The sample is centrifuged to separate and concentrate the platelet-rich plasma — a gold-coloured serum rich in growth factors.
Graft Treatment
Extracted grafts are stored in PRP solution during the procedure — bathing follicles in growth factors before implantation.
Scalp Injection
PRP is injected into the recipient scalp — stimulating native follicles and creating an optimal environment for graft integration.
DHI Implantation
Pen DHI proceeds as normal — grafts implanted with the Choi pen, directly into the PRP-prepared scalp.
Post-Procedure PRP
Remaining PRP is applied to the donor area — accelerating healing, reducing scarring, and stimulating regrowth in donor follicles.
Stem Cell DHI vs Standard DHI: What's the Difference?
Standard Pen DHI is already superior to conventional FUE — the Choi pen technique produces higher density and better graft survival than channel-and-place FUE. Stem Cell DHI enhances these results further by adding the biological environment that follicles need to integrate optimally.
The key clinical differences:
- Higher graft survival percentage: PRP-treated grafts have enhanced viability compared to grafts stored in standard saline solution
- Reduced shock loss: The growth factor environment minimises the severity of the temporary shedding phase at 4–8 weeks
- Earlier growth onset: Some patients begin seeing new hair emergence at 2–3 months rather than 3–4 months
- Better donor recovery: The donor area heals faster and more completely with PRP treatment
- Stimulation of surrounding native hair: PRP injected into the scalp can revitalise thinning native follicles in the vicinity, providing an additional density benefit
Who Benefits Most From Stem Cell DHI?
While all patients benefit from the PRP protocol, Stem Cell DHI is particularly recommended for:
- Advanced hair loss (Norwood 5–7): Large sessions benefit most from the enhanced graft survival
- Patients over 45: Healing efficiency and follicle regeneration tend to benefit more from the growth factor environment
- Smokers: Smoking significantly impairs circulation and healing; PRP partially compensates for this
- Second or revision procedures: Scar tissue from previous procedures creates a more challenging environment — PRP helps grafts integrate despite this
- Patients with diffuse thinning: PRP's stimulation of native follicles can produce a broader density benefit
- Eyebrow transplant: The small graft count makes every single follicle's survival critical — PRP maximises it
Is It Safe? Is It Proven?
PRP for hair restoration is well-established in medical literature with hundreds of published studies demonstrating its safety and efficacy. Because the PRP is derived from the patient's own blood, there is no risk of allergic reaction or rejection. The procedure adds approximately 30–45 minutes to the overall session.
