Noticeable Hair Thinning or Receding Hairline? Seoul Rappoel’s Rejuran Scalp PDRN Hair Treatment



Hair loss is no longer just a male concern — more and more women are experiencing receding hairlines and thinning at the crown. When hair-growth shampoos and supplements fail to deliver results, the real issue often lies at the follicle level: poor microcirculation and declining follicular cell activity cause hair to enter the resting (telogen) phase and stop growing. Seoul Rappoel Clinic offers Rejuran scalp PDRN injection therapy, delivering PDRN directly into the scalp dermis to activate the hair growth mechanism at the follicle level — a non-surgical, non-hormonal approach to hair restoration.

How PDRN Promotes Hair Growth

PDRN (Polydeoxyribonucleotide) works through multiple biological mechanisms in scalp treatment:

  • Angiogenesis: PDRN stimulates the formation of new micro-blood vessels in the scalp, increasing oxygen and nutrient supply to hair follicles
  • Anti-inflammatory repair: Improves chronic scalp inflammation, creating a healthier environment for follicle growth
  • Follicle stem cell activation: PDRN signaling molecules can awaken dormant telogen-phase follicles and shift them into the anagen (growth) phase
  • DHT protection: Improves the follicular microenvironment to indirectly reduce DHT-related follicle damage
  • Collagen regeneration: Strengthens the dermal structure of the scalp, providing better support for follicles

Rappoel’s Rejuran Scalp Protocol

  • Target zones: Hairline, vertex thinning area, and widened part line as priority treatment zones
  • Injection technique: Ultra-fine 32G needle with multi-point micro-injections across the scalp dermis
  • Treatment interval: Every 3–4 weeks, with 3–5 sessions comprising a full course
  • Session duration: Approximately 20–30 minutes per session
  • Combination therapy: Can be combined with growth factor serums and low-level laser therapy for enhanced results

Ideal Candidates

  • Early-to-moderate androgenetic alopecia (male or female pattern hair loss)
  • Postpartum hair loss (telogen effluvium) requiring accelerated recovery
  • Stress-induced hair thinning
  • M-shaped receding hairline or vertex thinning
  • Individuals wishing to avoid oral hair-loss medications (e.g., finasteride) and their potential side effects
  • Adjunctive maintenance therapy after hair transplant surgery

Expected Results

  • After 1–2 sessions: Reduced daily hair shedding; improved scalp oiliness and sensitivity
  • After 3–4 sessions: New vellus (fine) hairs begin to emerge; increased density at the part line
  • After full course: Noticeable increase in hair volume; new hairs gradually become thicker and longer
  • Maintenance: One booster session every 3–6 months after completing the initial course

Frequently Asked Questions

Is scalp Rejuran injection painful?
You may feel mild pricking sensations, but with a 32G ultra-fine needle, topical anesthetic, and skin cooling, most patients tolerate it easily. Each session takes only 20–30 minutes.
Rejuran vs oral finasteride — which is better?
They work through different mechanisms. Oral finasteride reduces hair loss by inhibiting DHT. Rejuran stimulates hair growth by improving follicular circulation and cell regeneration. Rejuran is a non-hormonal therapy with no systemic side effects, ideal for those wishing to avoid oral medication or those who cannot tolerate it.
How soon do results appear?
Reduced hair shedding is often noticeable after 1–2 sessions. New baby hairs typically emerge 2–3 months after 3–4 sessions, with the complete hair growth cycle taking about 6 months. The most visible results appear after completing the full 3–5 session course.
How is this different from a hair transplant?
Hair transplant surgically relocates follicles from the donor area to the recipient area. Rejuran scalp injections awaken existing dormant follicles. Rejuran is suitable for early intervention and post-transplant maintenance; transplants are for areas with no remaining active follicles.
Can I wash my hair after the treatment?
We recommend waiting 24 hours before washing, using lukewarm water and gentle cleansing. Avoid strenuous exercise and heavy sweating for 24 hours. You can resume normal activities and fly the same day.
