"I was skeptical. Around month three my barber asked what I was doing differently. That was enough for me."

Science & results
Studied in trials. Explained in plain language.
Red light at 650 nm is absorbed by the mitochondria inside follicle cells, raising cellular energy and blood flow so dormant follicles re-enter growth. Decades of published research back the mechanism. Here is the evidence in plain language, and what it looks like when it works.
Evidence 2
Recognized mechanism: photobiomodulation
Red light absorption by cytochrome c oxidase in mitochondria increases ATP production and microcirculation, the pathway that shifts follicles back into the anagen (growth) phase.
Evidence 3
FDA-cleared device class
Laser therapy caps in this class are FDA-cleared for the treatment of androgenetic alopecia in men and women, the same regulatory pathway used by clinical devices.
What to expect
Hair grows on its own schedule. Here is the honest one.
Most people who quit do it in month two, expecting month-four results. Knowing the real timeline is the difference between stopping early and seeing it through.
Day 1
Ten minutes, and that's it
You put the cap on, it runs its cycle, it shuts itself off. Nothing to feel, nothing to clean up. The whole job is showing up again tomorrow.
Month 1
Less in the drain
The first change most people notice isn't growth, it's what stops. Less shedding in the shower, less on the pillow. Quiet, but it's the signal that follicles are waking up.
Month 3
Someone else notices
New growth comes in fine and short first, most visible along the part and hairline. This is usually where a barber, a partner, or an old photo makes the comparison for you.
Individual results vary. Consistent use as directed is required.
In their words
The part nobody talks about. Getting yourself back.
I stopped planning my life around lighting
"I used to check every photo before anyone else saw it, and I always picked the seat with my back to the window. That's gone now. I don't think about my hair when I walk into a room."
I wear it down again
"For two years everything was a bun or a clip because I didn't want anyone seeing my part. Last month I wore my hair down to a wedding and my sister noticed before I said a word."
My barber asked first
"He's cut my hair for nine years. He said there was more to work with on top, and asked what changed. I've never been so happy to answer a question at a barbershop."
The shedding stopped bothering me
"The first thing I noticed wasn't growth, it was that the drain stopped filling up. That alone took a weight off before I saw anything in the mirror."

FAQ
Questions, answered straight.
Red light in the 650 nm range is absorbed by mitochondria in hair follicle cells, increasing cellular energy (ATP) and blood flow to the scalp. This shifts dormant follicles back into their active growth phase. The mechanism is called photobiomodulation and has been studied in peer-reviewed clinical trials.
