How Does LLLT Work?
Low-level light therapy (LLLT) works for hair growth by using low-intensity light energy to stimulate cellular activity in hair follicles. This process is also known as photo biomodulation.
The light waves penetrate the scalp and reach the base of the hair follicles, where they trigger metabolic changes that increase energy production, improve cellular function, and promote hair growth.
LLLT stimulates the production of adenosine triphosphate (ATP), the fuel source for cells, which leads to increased cellular activity and division. Additionally, LLLT improves blood flow and oxygenation to the scalp, which supports the growth and health of hair follicles. By using LLLT, hair follicles can become stronger and healthier, resulting in thicker and fuller hair.
How Our TripleWave™ Tech Works
TripleWave™ Technology uses three types of red light (615nm, 635nm, and 650nm) to target different layers of your scalp.
Each wavelength reaches a different depth, helping to wake up hair follicles from top to bottom. This means more energy, better blood flow, and faster, fuller hair growth.
It’s like giving your scalp a full-coverage power-up, not just hitting one layer like older devices.
What Determines LLLT Success?
1. Wavelength (Light Type):
This is the specific colour of red light used. The most effective range for hair growth is 600–700nm, with 650nm being the gold standard.
2. Irradiance (Power):
This measures how much light energy hits your scalp. Think of it like how bright a torch is when held close. Too low, and it's ineffective. Too high, and it can cause diminishing returns.
3. Fluence (Dosage):
This is the total amount of energy delivered over time. It's not just about power—it’s also about how long and how evenly the light is applied. The RedLight Hat Pro is designed to hit the ideal balance: effective energy, full scalp coverage, and a proven 15-minute daily routine.
Is laser still the most advanced option?
Not anymore. Lasers use pinpoint beams that only cover small areas of the scalp, often under 5mm² per diode.
Our TripleWave™ diodes penetrate just as deep as lasers but cover up to 10x more scalp per diode.
That means more consistent coverage, better follicle activation, and no gaps in treatment.
