• Device type: headband
• Uses: red and blue light
• Treatment time: 15 minutes

• Why it’s Vogue-approved: Using targeted red light therapy this clever hat works by increasing ATP production within hair cells, essentially energising sluggish ones and encouraging them to rejuvenate. Better ATP production also means a better environment for scalp health in general to flourish, which means it’s good if you suffer from an itchy or flaky scalp too.

Foreo

FAQ™ 301 LED Hair Strengthening Scalp Massager

• Why it’s Vogue-approved: Designed to be used in conjunction with hair growth treatments like serums and drops, this LED device enhances absorption by temporarily dilating the pores on the scalp to allow active ingredients to penetrate deep into the follicles. The LED also helps extend the hair growth phase of each strand, helping to boost growth and strength and defend against further hair loss.
• Device type: Brush
• Uses: red light (650 nm)

FAQs

How do LED devices work for hair growth?

“LED hair growth devices typically use low-level light therapy (LLLT) to stimulate hair follicles,” explains Dr Bessam Farjo, hair loss expert and hair transplant surgeon at Farjo Hair Institute. “The light penetrates the scalp and is absorbed by cells within the follicle, helping to increase energy production and support hair growth. Some advanced devices use medical-grade lasers rather than LEDs (still using light energy), offering more focused light delivery. This can enhance penetration and potentially improve outcomes.”

Carole Amar, founder of NOOĀNCE Paris adds, “LED hair growth devices use photobiomodulation to stimulate hair follicles. Red and near-infrared wavelengths, particularly at 650 nm, penetrate the scalp to activate cellular energy in the follicles, increase blood circulation, and reduce inflammation. The wavelength is especially important, as it targets the optimal depth to reach the hair follicle bulb; a critical factor since different wavelengths interact with different layers of the skin. This specific wavelength is the most widely recognized for its effectiveness in promoting hair regrowth. By encouraging dormant or weakened follicles to re-enter the active growth phase (anagen), this light therapy creates an ideal environment for healthier, stronger, and denser hair over time.”

Can LED hair devices improve scalp health?

Given that hair health is so dependent on the condition of your scalp, LED devices can also offer huge health benefits if you are especially concerned about your scalp. “Yes, beyond promoting hair growth, these devices help improve overall scalp health by boosting blood flow and nutrient delivery to the scalp, as well as reducing inflammation,” explains Amar.

How is the technology different to that of an LED face mask?

“While both facial and hair devices rely on photobiomodulation, their design, light intensity, and wavelength application are tailored to different biological targets,” adds Amar. “LED face masks are typically designed to target surface-level skin concerns such as fine lines, while hair growth devices, such as helmets, are engineered to reach deeper into the scalp. Devices for the scalp can combine two types of light sources; lasers (at 650 nm) penetrate deeply and with precision to directly stimulate hair follicles at the root. Their action is focused and targeted. LEDs provide a broader, more diffuse stimulation at the cellular level, boosting ATP production, improving overall scalp health, and supporting the follicular environment. This combination forms a complementary system: lasers offer depth and accuracy, while LEDs ensure wide coverage and consistent cellular activation. Together, they create a mesh-like stimulation pattern that differs significantly from LED face masks, which are not designed to treat structures as deep as the hair follicles.”

How often should I use an LED hair/scalp device?

While it depends on the hair device, every expert will tell you that consistency of use is key if you want to see visible results. “Most manufacturers recommend using an LED or laser hair device around three times per week,” says Farjo. “Sessions are usually brief; some as short at 90 seconds per area of the scalp and usually no more than 10-15 minutes maximum, depending on the device. Regular and consistent use is essential, as results tend to develop gradually over several months.”

How long will it take to see results?

“Visible results usually start appearing after 12 to 16 weeks of regular use, though improvements can be seen in hair texture and scalp condition sooner,” says Amar. “Full hair growth benefits typically take 4 to 6 months, as hair growth cycles require time to show noticeable changes.”

Are they safe to use?

“Yes, low-level light therapy is generally considered safe and well-tolerated,” Farjo adds. “It’s non-invasive and does not involve heat, so side effects are minimal. Devices on the market today, particularly those that are FDA-cleared or CE-marked, have typically undergone safety testing. However, users with photosensitivity or scalp conditions should consult a hair loss expert before starting treatment.”

Is there anyone who won’t see results after using one?

“Those with advanced baldness where hair follicles are no longer present or fully destroyed,” says Amar. “A hair follicle can remain dormant but still viable for up to two years. During this time, even if no hair is being produced, it is possible to reactivate these follicles with consistent photobiomodulation. Therefore, many users with thinning hair or inactive follicles (that aren’t fully destroyed) can benefit from stimulation with hair growth devices.”
