“In my experience, yes, red light therapy can stimulate hair growth and slow hair loss in some patients,” Dr. Ross Kopelman, a hair transplant surgeon and restoration specialist, told The Post.
“That said, I do not put it at the top of my treatment list.”
Here’s all the things you need to know about red mild therapy for hair loss — including how to discover a machine that truly shines.
Does red mild therapy for hair loss work?
“Red LED is scientifically proven technology that has been demonstrated to be effective in proper studies,” said Dr. Jessica Weiser, a board-certified dermatologist who works with KeraFactor, a company specializing in hair loss and revitalization therapies.
In one research, dermatologists discovered that low-level laser red mild therapy was just as efficient at regrowing hair as minoxidil, a medication generally used to deal with sample hair loss.

In another, girls with androgenetic alopecia noticed a 37% increase in hair rely after utilizing the treatment in contrast to a placebo group.
Still, Weiser said that the hair-growth market is packed with fads that don’t live up to the hype, including utilizing rosemary oil and rice water on the scalp.
She also recommends against taking dietary supplements with sprawling ingredient lists and steering clear of extraordinarily high-dose biotin. While the vitamin can help shield hair from breakage, she said it gained’t truly grow new strands.
How does red mild therapy assist hair growth?
“Red LED works through a process known as photobiomodulation,” Weiser said.
The red mild stimulates the mitochondria in the cells of the hair follicles to produce more power molecules, which may reactivate dormant follicles and prolong the growth part of the hair cycle, she explained.
“This results in more effective and more rapid growth of the hair within each hair follicle,” Weiser said. “Additionally, LED reduces inflammation and stimulates circulation at the scalp and hair follicle level to further support a healthier scalp and improved hair growth.”
But getting outcomes requires a regular, long-term dedication.
“The reality is, you have to use it consistently, usually three times a week for 15 to 20 minutes, for months to see any difference,” Kopelman said.
Are there any downsides to utilizing red mild therapy for hair loss?
“In terms of side effects, it is generally very safe,” Kopelman said. “You might experience mild scalp warmth or tingling, but that is about it.”

The larger issues, he famous, are price and the time required to keep outcomes.
“Good devices are expensive, and if you stop using them, any benefits you gained can be lost,” Kopelman explained.
“It is also not a standalone cure,” he added. “For most people, it works best as part of a comprehensive plan that might include topical or oral medications.”
What issues most when selecting a red mild machine?
“The two most important things are wavelength and power density,” Kopelman said. “You want a device that uses clinically studied wavelengths, usually around 650 nanometers, and delivers enough energy to the scalp.”
Bulb rely is another key issue.
“Many of the caps, helmets, and hats have minimal scalp coverage with fewer than 100 to 150 bulbs or lasers,” Weiser said.
“Look for devices with high bulb count, such as Kerafactor’s KeraFlex Duo that contains 312 medical grade laser diodes and dual wavelength technology,” she beneficial. “[That’s] the highest bulb count on the market, delivering the most robust treatment with a very short treatment time.”

Kopelman emphasised the significance of coverage.
“A cap that treats your entire scalp is better than a small handheld unit that requires constant repositioning,” he said.
Price ought to also be a red flag when it’s too good to be true.
“I would avoid cheap LED caps in general, partly because they will have minimal if any efficacy and partly because they probably do not have consistent wavelengths,” Weiser said.
Is FDA approval important for red mild therapy devices?
“I always tell patients to go with an FDA cleared device,” Kopelman said.
That clearance doesn’t essentially guarantee outcomes, he explained, but it does make sure the machine meets sure security and manufacturing requirements.
“The caps you see on Amazon or even on ultra cheap sites like Shein are often unregulated, may not deliver the right wavelength or power, and could be a complete waste of money,” Kopelman said.
How are you able to enhance the effectiveness of your red mild machine?
“To further increase the efficacy of red LED hair and scalp treatment, there are certain scalp serums that contain growth factors and other active ingredients that can further enhance results,” Weiser said.
Look for merchandise that embody quite a few follicle-stimulating growth elements and scalp-supporting peptides, along with lively ingredients like PDRN, which promotes mobile turnover and regeneration, and nanofluorosomes, which give both anti-inflammatory and anti-androgenic advantages.
At the end of the day, Kopelman views red mild therapy as a helpful instrument somewhat than a must-have treatment.
“It can be a good option if you cannot take hair loss medications, if you are pregnant or breastfeeding, or if you want to add something noninvasive to your routine,” he said.
“But overall, I do not usually recommend it as my first-line approach because the price can be high, protocols vary widely and compliance is everything — and that is where most patients fall short.”
