PRP vs. LLLT (Low-Level Laser Therapy) for Hair Loss: Which Works Better?
|
Table of contents
Hair loss can feel overwhelming. When you notice extra strands in the shower or a thinning hairline, the first instinct is to look for solutions that actually work. Two of the most discussed treatments in the world of hair growth today are Platelet-Rich Plasma (PRP) therapy and Low-Level Laser Therapy (LLLT). Both are non-surgical, clinically backed, and promise to revive struggling follicles, but which one should you choose?
In this blog, we’ll explore PRP vs. LLLT in detail: how they work, their benefits, and what to expect from each. Then, we’ll look at why addressing the root cause of hair thinning is essential and introduce a smarter approach to achieving lasting results.
What is PRP Therapy?
Platelet-Rich Plasma therapy involves using your body’s own platelets to stimulate hair growth .
Here’s how it works:
A small amount of your blood is drawn and spun in a centrifuge to isolate platelets.
This platelet-rich plasma, full of growth factors, is then injected into the scalp.
- The growth factors signal follicles to heal and re-enter the growth phase.
Why people choose PRP:
Uses your body’s natural resources
Can improve follicle health and density
- Typically performed in clinical settings
What to keep in mind:
Multiple sessions are required (usually 3–6)
Some discomfort during injections
- Costs can be high and vary by clinic
What is LLLT (Low-Level Laser Therapy)?
LLLT is a non-invasive, light-based therapy that uses low-level lasers to stimulate follicles at a cellular level.
Emits red light at a specific wavelength (usually around 650 nm)
Improves blood flow and cellular metabolism in the scalp
- Encourages follicles to transition from the resting (telogen) to the active growth (anagen) phase
Why people choose LLLT:
Completely non-invasive and pain-free
No downtime — just a few minutes per session
Works for both men and women with thinning hair
What to keep in mind:
Requires consistent use (several times a week)
Best results seen after 3–6 months
- Works best when paired with other supportive treatments
PRP vs. LLLT: A Healthy Comparison
Both treatments aim for the same goal: stimulating hair growth . But the way they do it — and the experience they offer — is different.

The truth? Neither is a magic bullet. Hair loss is multi-factorial — hormones, stress, nutrition, inflammation, and scalp health all play a role. That’s why many experts recommend pairing solutions or choosing a system that addresses multiple angles.
Why Root-Cause Healing Matters
Here’s the hard truth: Quick fixes rarely last. If you’re only treating the surface without targeting underlying triggers like hormone imbalance or nutritional deficiencies, the results won’t stick.
