Hair loss can be stressful, affecting confidence and quality of life — whether it’s thinning hair, early pattern baldness, or gradual shedding. In dermatology and aesthetic medicine, two popular non-surgical hair restoration treatments are gaining attention today: the Hair Threading Treatment (also known as PDO scalp threads) and PRP (Platelet-Rich Plasma) Therapy. Both aim to stimulate hair regrowth without surgery, but they work very differently. Let’s break down what each does, how they compare, and how to choose the best option for your hair loss goals.
What Is Hair Threading Treatment (PDO Threads)?
Hair Threading Treatment (often called PDO scalp threading) involves inserting tiny, absorbable threads made of polydioxanone (PDO) into the scalp. These medical-grade threads are placed directly in areas of thinning to create a micro-environment that encourages natural hair regrowth.
How It Works
- PDO threads stimulate collagen production and activate fibroblast cells important for tissue repair.
- They improve blood circulation around hair follicles, bringing oxygen and nutrients to dormant or weakened hair roots.
- The threads create a controlled biological response, essentially “telling” the scalp to begin repair and regeneration.
Benefits
- Minimally invasive: No cutting, no stitches, no major downtime.
- Improves scalp health: Better circulation and collagen can strengthen hair roots.
- Gradual, natural results: Hair often appears thicker and healthier over months as regeneration continues.
- Can be combined: Works well with other therapies like PRP, GFC, or mesotherapy to maximize results.
Expectations & Timeline
- Typically, 2–3 sessions spaced weeks apart are recommended.
- Threads dissolve over several months, but their stimulatory effect can last even longer.
- Visible improvement often starts after 8–12 weeks.
What Is PRP (Platelet-Rich Plasma) Therapy?
PRP therapy increases growth of new hair by using your own blood. A small volume of blood is drawn, spun in a centrifuge to concentrate platelets and growth factors, and then injected back into the scalp.
How It Works
- PRP is rich in growth factors and cytokines that can encourage dormant hair follicles to re-enter the growth phase.
- When injected into the scalp, these growth factors may improve blood supply and follicle health, potentially promoting denser, thicker hair.
Benefits
- Natural & safe: uses your own blood; there is little chance of an adverse reaction.
- Non-surgical: Quick sessions with little to no recovery time.
- Well-studied: Numerous studies show improvements in hair thickness and density with consistent sessions.
Expectations & Timeline
- Usually, 3 initial sessions one month apart, with maintenance sessions every 3–6 months.
- Results are often gradual, with full benefits visible around 3–6 months after the start.
Hair Threading vs PRP -Detailed Comparison
| Feature/Goal | Hair Threading (PDO Threads) | PRP Therapy |
| Mechanism | Physical stimulation, collagen induction, scaffolding effect | Growth factor injection from your own blood |
| Invasiveness | Minimally invasive | Injectable, minimally invasive |
| Best for | Early to moderate thinning, scalp health improvement | Mild to moderate hair loss from miniaturized follicles |
| Number of Sessions | ~2–3 sessions | ~3–6 sessions plus maintenance |
| Downtime | Little to none | Little to none |
| Pain Level | Mild to moderate with local numbing | Mild injections with optional numbing |
| Cost | Moderate | Moderate-to-high |
Scientific Evidence Snapshot
- PRP has multiple clinical studies showing increased hair density and thickness in pattern hair loss.
- PDO thread treatments are newer, with research indicating scalp stimulation and improved follicle environment.
- Emerging evidence suggests combining PDO threads with PRP can harness the benefits of both scaffold support from threads plus growth-factor stimulation from PRP.
Which Is Better? A Simple Guide
✔️ Choose Hair Threading If:
- You want a structural, regenerative stimulation of your scalp.
- Your hair loss is early to moderate, and you want to strengthen the hair environment.
- You prefer fewer sessions with long-lasting stimuli.
✔️ Choose PRP If:
- You want growth-factor-focused stimulation rooted in your own biology.
- You have mild thinning where follicles are still active.
- You are fine with multiple sessions over months for gradual improvement.
Best Results Often Come from Combination Plans: Many dermatologists now recommend combining PDO threading with PRP threads set the stage by improving circulation and collagen, while PRP nourishes follicles with powerful growth signals.
Realistic Results & Expectations
Hair regrowth treatments take time and consistency. Neither PRP nor PDO threads are instant cures. Expect visible improvements within months, not days. And while both can slow shedding and improve density, results vary depending on genetics, age, scalp health, and degree of follicle miniaturization.
Both treatments work best when combined with:
- Dermatologic check-ups
- Nutritional support
- Scalp care routines
- Adjunct therapies like topical minoxidil or GFC
