Does Red Light Therapy Work for Hair Loss? Inside the CurrentBody LED Hair Growth Helmet.
As a skin expert with over 35 years of experience, I’ve spent much of my career working professionally with LED (Light Emitting Diode) technology. I’ve seen firsthand how specific wavelengths of light can support the skin’s repair processes, increase collagen production, boost cellular energy and influence everything from inflammation to wound healing.
Hair thinning and hair loss are extremely common concerns that affect both men and women. For many people, pinpointing the exact cause is difficult. It is often linked to hormones, stress, diet, medical conditions, weight loss injections or simply genetics. Because LED supports cellular repair and energy production, it makes complete sense to use the same technology to support scalp health and encourage stronger hair growth.
However, there is a catch. Unfortunately, it's not just as simple as taking the LED device you use on your face and popping it on your scalp for 10 minutes.
I’m excited to share that CurrentBody has given me an exclusive 20% discount code for their LED devices, but it’s only available for a limited time. Keep reading to discover the code and learn exactly what I, as a skin expert, look for in an LED hair growth helmet to ensure it truly delivers visible results.

The science behind LED and hair growth
LED may feel like the technology of the moment, but it is far from new. It was first explored by NASA engineers who used red and near-infrared LED light to support plant growth in space. During testing, researchers noticed accelerated wound healing and accelerated cellular repair in the skin. This sparked decades of clinical interest in how specific wavelengths of light can influence the body’s natural regeneration processes.
Think of LED as a battery charger for your cells, or like turning on a light switch. Light Emitting Diodes (LEDs) work by delivering precise 620-660nm wavelengths into different layers of the skin to help, renew, repair and restore cellular function. These wavelengths interact with the skin cells that surround the hair follicle, improving the follicle’s environment and in turn, helping it to grow stronger hair.
Red and near-infrared light support hair growth by influencing how your cells behave. LEDs encourage hair follicles to function more efficiently and remain in the growth phase for longer. This is particularly important for the dermal papilla, the “control room” that kick-starts and maintains hair growth.
Here is an in-depth look at how LED supports healthier, stronger hair:
1. Boosts cellular energy (ATP production)
LED stimulates ATP, the energy your hair and skin cells rely on to function. As we age, our ATP levels naturally decline. This impacts both the skin and hair. LEDs help increase ATP, which energises the dermal papilla and thus supports more productive hair growth.
2. Encourages a longer growth phase (anagen phase)
Hair thinning often happens because the anagen phase becomes shorter, and more hairs shift into the resting or shedding phase (telogen phase). This results in weaker, finer strands. LEDs help extend the anagen phase by improving cellular efficiency, allowing follicles to produce stronger, more resilient hair.
3. Improves scalp blood flow
Red and near-infrared wavelengths help increase local circulation. Better blood flow delivers more oxygen, nutrients and growth factors to the follicle. This creates an ideal environment for growth and repair.
4. Reduces inflammation around the follicle
Inflammation can disrupt follicle function and contribute to thinning. LED helps calm inflammatory processes, supporting a healthier scalp and a more stable growth cycle.
5. Strengthens existing follicles
LED cannot create new follicles, nor can it reactivate hair follicles that have completely shut down. It can, however, strengthen active hair follicles, helping them produce thicker, denser strands.
6. Supports overall scalp health
By improving cellular energy, circulation and oxygenation, LED helps maintain a healthier scalp. This is the foundation of long-term hair growth and resilience.
Overall, LED works at the base of the follicle, particularly within the dermal papilla and hair bulb. It boosts their energy and signalling pathways so the follicle can stay in the growth phase and produce stronger, more robust hair over time.
Who will benefit from using an LED Helmet?
Anyone noticing recent thinning or increased shedding
If your ponytail feels smaller, your parting looks wider, or you are seeing more hair in your brush or shower, and it is not seasonal shedding, LED can support the follicles that are still active and responsive.
People experiencing early signs of androgenetic alopecia
This is often known as genetic thinning or pattern hair loss. It is the most common cause of gradual thinning in both men and women. It is influenced by a mix of genes, hormones and age. The condition shortens the growth phase of each strand. LED can help extend this stage and support stronger regrowth.Those with stress-related hair changes
Periods of emotional or physical stress can increase cortisol. This shortens the anagen (growth) phase. The hair then spends more time resting or shedding. LED can help stabilise the cycle by improving cellular energy and reducing scalp inflammation.Anyone experiencing hormonal hair changes
Postpartum, perimenopause, menopause and even post-menopause can cause a sharp drop in oestrogen. This can push many follicles into the telogen (resting) phase simultaneously. LED can help support the follicles through this transition and encourage a return to healthier growth patterns.People with weakened or stressed hair follicles
Inflammatory scalp conditions, nutritional deficiencies, illness, postpartum recovery, and ageing can all compromise follicle strength. LED helps boost cellular repair and improve circulation around the follicle.Hair thinning after weight-loss injections
Changes in nutrients, hormones and cortisol can create a shock response in the hair cycle. This may lead to increased shedding. LED can help support recovery by energising the active follicles and improving scalp health.
Who Will Not Benefit From Using an LED Helmet
LED helmets are effective only when follicles are active or dormant. They cannot bring a dead follicle back to life, and they cannot create new follicles.
You are unlikely to see results if:
You have long-term bald patches
Long-standing baldness usually means the follicles are no longer active. LED can energise active follicles. It cannot regenerate ones that no longer exist.
You are undergoing chemotherapy
You should not use LED during chemotherapy. You can use it after treatment once your medical provider confirms it is safe.You have photosensitive disorders or are taking medication that triggers photosensitivity
Medical advice is essential in these cases because LED could worsen symptoms.You experience light-induced headaches or have epilepsy
Light-based devices can trigger symptoms and should be avoided.
Expected Results and Realistic Timelines
LED hair growth devices work by supporting the follicles you already have. So while results can be impressive, they certainly aren’t instant. Here’s what a realistic journey looks like:
0–4 weeks: Early cellular changes
You won’t see visible hair growth at this stage. Instead, LED is working behind the scenes to increase ATP production, improve scalp circulation, and reduce inflammation. Many people notice less itchiness or irritation and a slight improvement in scalp comfort.
8–12 weeks: Reduction in shedding
This is usually the first measurable change. As follicles receive more energy and stay in the anagen (growth) phase for longer, shedding often slows. Your hair may feel a touch fuller at the roots. This stage is subtle but important because it’s a sign the follicle is responding.
12–16 weeks: Early regrowth and improved density
Fine, short “baby hairs” often start appearing along the hairline or parting. Existing hair may feel stronger or look thicker because the follicle is producing better-quality strands.
16–24 weeks: Noticeable improvements
Most people see visible changes in volume, density and overall scalp coverage by this point. For many, their ponytail feels fuller and their parting appears narrower. Photos (taken monthly) make the difference clearer than the mirror will.
6–12 months: Maximum results
LED delivers its best results with long-term consistency. Hair grows in cycles, so it can take a full 12 months for all follicles to complete a growth cycle under LED stimulation. Results tend to plateau after this, so ongoing maintenance treatments are key.
What to expect overall
LED won’t create new follicles, but it can significantly strengthen active ones. With proper use, many people see denser, thicker, healthier-looking hair and a noticeable reduction in shedding
How to choose an effective LED device
Choosing the right LED device is essential if you want genuine results. Here is what to look for before you invest:
Correct wavelengths (620-670nm)
For hair growth, the device must use red wavelengths within the 620–670 nm range. These wavelengths have been shown to reach the hair follicle and influence the growth cycle. This is why placing a face LED mask on your scalp will not work as effectively. Face masks are designed for superficial skin layers, not follicle depth.Full-scalp coverage
Avoid small handheld LED tools that require moving across the head. They often give inconsistent coverage and are difficult to use regularly. A helmet-style device ensures the light evenly reaches all areas of the scalp.Visible before-and-after results
A reputable device should show real before-and-after images specifically for hair growth. This indicates both evidence and consumer usability. If a brand cannot provide this, it is usually a red flag.Proper sizing options
Fit matters. If the helmet is too large, the LEDs will sit too far from the scalp, reducing effectiveness. A good device should offer sizes or an adjustable fit to ensure close contact with the head.
CurrentBody LED Hair Growth Helmet
I have done the research for you, and here is why the CurrentBody LED Hair Growth Helmet is the best LED hair growth device:
Clinically proven to improve hair density and increase hair growth rate by up to 123% in 12 weeks, making it one of the strongest evidence-based at-home options available.
Used 2 x LED wavelengths (620nm and 660nm). These penetrate deeply into the scalp to energise the hair follicle and support cellular repair.
Red light at 620 nm helps reduce inflammation and supports scalp health.
660 nm red light reaches the hair bulb and dermal papilla. This is crucial for improving energy production, extending the growth phase, and strengthening hair at the root.
The helmet design provides full-scalp coverage, ensuring consistent, even light exposure.
Available in two sizes (medium and large), for a secure, close fit.
Hands-free, so you can use it while ironing, watching TV or getting ready in the morning.
Does it actually work?
Healthy hair grows about 1–1.25 cm per month, and that is before diet, stress, illness, age and hormones slow things down. LED doesn’t “force” hair to grow. Instead, it re-energises active follicles, supports the dermal papilla, and helps keep hairs in the growth phase for longer.
Daily use is key. The studies behind this device show visible improvements in 12–16 weeks, with fuller edges, less visible scalp along the parting, and stronger, denser new growth.
How to use the CurrentBody LED Hair Growth Helmet:
Take photos before you begin. You see your hair every day. The changes are gradual, so photos are the best way to track progress.
Consistency is key. I recommend using it daily for best results on a clean, dry scalp.
You can use the helmet alongside your usual hair-growth serums or scalp treatments, but apply them after your LED session.
Make it part of your routine so it becomes effortless.
