It used to be that we had to stay up late to get pitched miracle hair regrowth devices that stop male-pattern balding in its tracks. These days? A scroll on social media at any hour can feel like you’re binge-watching late-night infomercials — the magic bullets are aplenty. Recently, laser hair growth devices have gained popularity.
“How often are the social-media campaigns leading with ‘Does this look like you?’ or ‘Does your hair do this?’ with corresponding potential vitamin deficiencies but no specifics?” asked Jess Poynter, a certified clinical trichologist and the founder of Scalp Haven Hair Studio. “That’s the overwhelming norm. Enter the latest ‘miracle product’ while also claiming it will be the last thing you’ll need, as it will finally cure all your issues. “
However, Poynter noted that the “fixes” only apply to specific conditions, and she fears this point is rarely discussed in reels, campaigns, and captions. Experts, including Poynter, emphasize the importance of understanding what laser hair growth devices can and cannot treat, as well as key considerations to make before choosing one. They shared their insights below.
Do laser hair growth devices work?
Hair loss experts say that laser hair growth devices can work as promised, but results can vary. It might be helpful to review and discuss what those promises entail.
“Laser hair growth devices are intended to prevent or reverse hair loss,” said Dr. Anna Chacon, MD, a clinical dermatologist. “They can also encourage hair growth and treat hair thinning.”
Dr. Chacon has seen the results go both ways. Some guys notice fuller heads of hair, while others don’t report a difference.
“The results vary person to person and seem to be inconsistent across the board, so it’s best to consult with your doctor to create the best plan of action for your desired results and you specifically,” Dr. Chacon said.
Dr. Viktoryia Kazlouskaya, MD, Ph.D., a board-certified dermatologist and CEO of Dermatology Circle PLLC, says she’s upfront wth patients, telling them, “Laser devices are less effective than FDA-approved medications.”
Still, Dr. Kazlouskaya echoed Dr. Chacon’s sentiments.
“They can still be helpful, especially for pattern hair loss,” Dr. Kazlouskaya said. “Low-level light therapy — LLLT — is the most extensively studied method, with numerous home-based and in-office devices available. They work by stimulating the mitochondria in hair follicles, encouraging hair growth. In-office hair specialists also use additional laser devices to stimulate the scalp and aid in medication delivery.”
What to consider before opting for laser hair growth
Dr. Chacon says it’s critical to do your homework before purchasing a laser hair growth device, which can retail for more than $500. In-office treatments can also be costly and time-consuming.
“You also want to make sure the product and ingredients are good quality that actually work so that you also don’t end up doing more harm than good to your hair,” Dr. Chacon cautioned.
Here’s what to consider before opting for laser hair regrowth.
Talk to a doctor
Hair loss experts stress that not every Rx is appropriate for every guy.
“Before investing in a device, it’s crucial to see a hair loss specialist to understand what type of hair loss you’re dealing with,” Dr. Kazlouskaya said. “Laser devices are most effective for pattern hair loss, but won’t help much with inflammatory or scarring types of alopecia.”
Dr. Chacon said some medications can interfere with treatments.
FDA clearance
Poynter prefers to direct clients toward FDA-cleared laser hair devices.
“This is not a measure of guaranteed regrowth after using the product,” she said. “However, having this [clearance on] the product says that this device has been reviewed for safety and performance.”
Decode the label
Next, you’ll want to learn the lingo used to describe laser hair treatments as you search for an Rx that has the best chance of working for you.
- Diodes. Diodes are tiny light sources. Poynter says guys hoping to preserve hair but who aren’t concerned about regrowth are usually happy with fewer diodes (80-100range), while those hoping to regrow hair will want to opt for a full cap in the 200-300-diode range.
- Wavelength. Wavelength indicates how deeply light penetrates the skin. “Ideally, to reach the systems that will improve hair regrowth and all its ‘supporting cast,’ a device would need to be in the 630-nm range,” Poynter said.
- J/cm2 Energy Dose. Poynter reported that this metric indicates “how much energy is getting to the scalp during each treatment. “Essentially, this is the indicator to see how effective this device will really be for someone,” she said. Poynter recommended looking for laser devices in the 3-6 J/cm² range for hair growth.
Discuss alternatives
It’s a good idea to consider options besides laser hair growth devices. Dr. Kazlouskaya suggests:
- FDA-approved medications, like finasteride and minoxidil
- Regenerative treatments, like PRP injections
- Ultrasound-based treatments like TED
Dr. Chacon suggests discussing serums — they aren’t just for skin — and supplements. She suggests checking labels for ingredients like:
- Vitamin B
- Biotin
- Keratin
- Iron
- Vitamin C
- Vitamin A
“Serums are applied directly to the hair and can help strengthen your hair and help with hair thinning,” Dr. Chacon said.
Laser hair growth products to consider
Still a bit confused about what to choose? Try these two expert-recommended laser hair growth devices.
- Original LaserCap. Poynter suggests the original LaserCap for at-home LLLT devices. “I’ve tried other devices, but something is always not quite right,” Poynter said.
- HigherDose Red Hat Light. For starters, Dr. Chacon likes that this product is FDA-cleared. “It helps with hair growth, strengthening the hair and reducing hair shedding,” she said. “It fits like a ball cap, so it’s super comfortable and adjustable. The treatment time is only 10 minutes, so it is very doable to work into your schedule.”
Takeaway
Laser hair treatments can help stimulate regrowth for men experiencing male pattern baldness. However, they aren’t a guarantee and are unlikely to help guys with hair loss caused by other issues, such as scarring. Consult with your healthcare team, such as a dermatologist, before trying one. They can help you determine if a device is worth trying and if any medications you’re taking increase your risk of issues. Experts recommend opting for an FDA-cleared device, which signifies that the product has undergone safety testing. Consider your goals (growth or preservation) when looking at diodes and wavelength. Alternatives, like medication and serums, may be a better fit for you.
