3 Advanced Hair Growth Techniques That Actually Work!
There are tons of hair growth remedies floating around, but the truth is, if it’s not working on a cellular level, it’s just hype. That’s why today, we’re diving into 3 advanced hair growth techniques that are backed by real science.
We’re talking red light therapy, PRP (platelet-rich plasma) therapy, and dermarolling—what they do, how they work, and how you can use them to extend the anagen phase (active hair growth phase), boost scalp circulation, and wake up dormant follicles! Let’s get into it!
Red Light Therapy – ATP Energy Boost for Faster Growth
Red light therapy is basically like flipping a switch on your follicles and saying, “Wake up, it’s time to grow!” And it's actually rooted in science.
How It Works
When red light (at 650–850nm wavelengths) penetrates your scalp, it stimulates mitochondria inside the follicle cells to produce more ATP (adenosine triphosphate). ATP is the energy powerhouse that fuels cell function, and more ATP means follicles stay in the anagen (growth) phase longer.
Why This Matters
- More Energy = More Growth – Follicles with more ATP don’t tap out early; they keep producing hair.
- Increased Blood Circulation – Red light stimulates tiny blood vessels, ensuring your follicles get the oxygen and nutrients they need.
- Reduces Shedding & Inflammation – It calms down inflammatory cytokines, which means less hair loss and healthier scalp conditions.
How to Use It
- At-home laser caps and combs for consistent scalp therapy.
- Professional in-clinic laser treatments for deeper penetration and faster results.
PRP Therapy – Your Own Growth Factors for Stronger, Healthier Hair
If you’re dealing with thinning edges, postpartum shedding, or early-stage hair loss, PRP therapy might be your best bet. This treatment uses your own blood’s platelets, which are LOADED with growth factors that stimulate hair follicles.
How It Works
A dermatologist draws a small amount of your blood, spins it in a centrifuge to separate the platelet-rich plasma (PRP), then injects it directly into your scalp. This plasma is packed with PDGF (platelet-derived growth factor), VEGF (vascular endothelial growth factor), and IGF-1 (insulin-like growth factor-1), all of which kickstart follicle regeneration and extend the anagen phase.
What This Means for Hair Growth
- Thicker hair – Growth factors activate follicle stem cells, making your hair denser and fuller.
- Better blood supply – PRP stimulates new blood vessel formation, so your scalp gets the nutrients it needs.
- Stronger follicles – PRP reduces inflammation and miniaturization, preventing further thinning.
How to Use It
- Done professionally by dermatologists or trichologists.
- Recommended for thinning edges, traction alopecia, and overall hair density improvements.
Dermarolling – Microneedling to Wake Up Dormant Follicles
Okay, let’s talk about dermarolling—aka microneedling for the scalp. If you want to revive thinning areas and make your hair growth serums work 10x better, this is the technique for you!
How It Works
A dermaroller with tiny needles (0.5mm–1.5mm) creates micro-injuries in the scalp, triggering the wound-healing process. This causes your body to release growth factors like PDGF and fibroblast growth factor (FGF-7), which signal your follicles to start growing again!
Why It’s Effective
- Boosts Follicle Activity – These tiny injuries jumpstart the follicle regeneration process.
- Increases Scalp Circulation – More blood flow = more oxygen and nutrients for your hair.
- Enhances Absorption of Growth Serums – If you use hair growth oils, peptides, or caffeine-based treatments, dermarolling helps them penetrate deeper for maximum results.
How to Use It
- At-home dermarollers (0.5mm–1.0mm) – Use 1–2 times per week with a growth serum.
- Professional microneedling (1.5mm–2.0mm) – Done in-office for deeper follicle stimulation.
Which One Should You Try?
If you’re dealing with slow growth, thinning, or weak strands, here’s how to decide:
✔ Use Red Light Therapy if you want to stimulate follicles and extend the growth phase.
✔ Try PRP Therapy if you need to wake up thinning areas and restore density.
✔ Incorporate Dermarolling if you want to supercharge your scalp and maximize hair growth products.
The key is science-backed hair care that works WITH your follicles...not against them.
