How does red light therapy help with hair loss?

Red light therapy at 630nm, 850nm and 940nm stimulates the mitochondria in hair follicle cells, increasing ATP production and cellular energy. This is associated with extended anagen (active growth) phase, reduced follicle miniaturisation, and improved scalp blood flow — all of which support hair density over time. The PHL Cap delivers three clinical wavelengths across 450 LEDs for full scalp coverage in every 20-minute session.

How long before I see results from the PHL Hair Growth Cap?

Hair growth is a slow biological process. Most users report reduced shedding within 6–8 weeks of consistent daily use, and visible density changes from 12–24 weeks. The clinical timeline for photobiomodulation hair research is 16–24 weeks of daily treatment. Consistency is the primary variable — irregular use significantly extends the timeline or prevents results.

How often should I use the PHL Cap?

Daily use of 20 minutes is the recommended protocol. Consistent daily treatment maintains the cumulative photobiomodulation stimulus needed for follicle transition through growth cycles. If daily isn't possible, minimum 5 sessions per week is the next best option — but results take longer.

What wavelengths does the PHL Cap use, and why three?

The PHL Cap uses 630nm, 850nm and 940nm. 630nm targets superficial skin and scalp tissue — supporting scalp health and surface-level blood flow. 850nm penetrates into the dermis where hair follicles are anchored — this is the primary wavelength for follicle photobiomodulation. 940nm reaches deeper tissue layers supporting scalp circulation and subcutaneous fat layer health. Using three wavelengths simultaneously addresses the follicle at every relevant tissue depth.

Can I use the PHL Cap with Minoxidil or other hair loss treatments?

Yes — red light therapy and Minoxidil have complementary mechanisms and are commonly used together in clinical settings. Minoxidil works on blood flow and follicle miniaturisation via a different pathway to photobiomodulation. There are no known negative interactions. You can use Minoxidil before or after your PHL Cap session — separate by at least 30 minutes to allow the topical to absorb.

Is the PHL Cap safe for all hair types?

Yes. Red and near-infrared light therapy is non-UV, non-ionising and produces no thermal damage at these power levels. It is safe for all hair types and scalp conditions including sensitive scalps. The PHL Cap is suitable for both men and women experiencing androgenetic alopecia (pattern hair loss). Consult a healthcare provider before use if you have a light-sensitive condition, are on photosensitising medications, or have active scalp lesions.

Health Benefits

Benefits that can come to you with consistent and proper use of the PHL Cap:

Stimulated Hair Growth

Quality Red light therapy is a safe, effective natural hair loss treatment that’s reliable for both male and female pattern baldness, as shown in countless studies. Red combined with NIR light at specific wavelengths and irradiance levels has increased hair counts, boosted hair thickness and helped people improve their appearance and confidence levels. If you’ve struggled with hair loss and unsuccessful treatments, here is the answer you have been seeking.

Red and NIR light therapy is backed up by a wealth of peer-reviewed clinical studies, trials, and meta-analyses. A 2019 meta-analysis examined 8 clinical studies, comprising a total of 11 double-blind randomised controlled trials. The quantitative analysis showed a significant increase in hair density for people who were treated with red light therapy.

Additional Benefits beyond hair growth and repair

Combat Brain Fog

This phenomenon could be due to many factors and pinpointing exactly what is the cause is often like trying to find a needle in a haystack. Just ask your doctor!

Dr Daniel Johnstone a medical scientist and lecturer at the University of Sydney’s medical research centre the Bosch Institute, has been involved in a number of animal experiments on the use of photobiomodulation for Alzheimer’s disease.

“If you can get the correct wavelength and intensity of light to vulnerable cells then you can afford them some level of protection against degeneration,” he stated “Red light is a mild stress which can stimulate cells to up-regulate their in-built defence systems to protect themselves against more severe subsequent insults.”

Your cells in your brain may be struggling to work effectively and if that is the case it is well worth supercharging via our smart cap and seeing the difference you will feel and potentially fend off any sinister diseases that might be heading your way.

Enhanced Brain Health

Amyloid deposits (an abnormal accumulation of proteins) in the brain are one of the major hypotheses for the cause of Alzheimer’s disease. Exposure to infrared light has been shown to decrease amyloid deposits in human neuroblastoma cells.

In 2017 a study was undertaken in which five patients with mild to moderate dementia were exposed to 12 weeks of daily transcranial infrared light therapy. They showed a significant improvement in Standardised Mini-Mental State Examination and Alzheimer’s Disease Assessment Scale tests at the end of the 12 weeks. Of note, there was also increased functionality, better sleep, and less anxiety and wandering in the trial participants. No adverse side effects were noted in the participants.

When Red light is directed at the brain, it impacts both the nerve cells and the blood vessels,” it concluded

THE SCIENCE

Red Light Therapy for Hair Loss: What the Research Shows

The PHL Hair Growth Cap delivers 630nm, 850nm and 940nm to the scalp via 450 LEDs. Three wavelengths address hair follicles at different tissue depths simultaneously. Here is the evidence base.

630nm

630nm Red Light: Scalp Skin and Surface Follicle Stimulation

630nm targets the superficial dermis and the upper portion of the hair follicle. Clinical research on 630nm photobiomodulation for hair growth includes improved ATP production in follicle cells, extension of the anagen (active growth) phase, and reduced scalp inflammation that contributes to follicle miniaturisation. Surface-level scalp health is a prerequisite for follicle function — and 630nm addresses this layer directly.

850nm

850nm Near-Infrared: Follicle Depth and Scalp Circulation

850nm penetrates deeper into the dermis where hair follicles are anchored. Research on 850nm scalp photobiomodulation covers improved dermal papilla cell activity, increased scalp blood flow and nutrient delivery, and reduced DHT-related follicle miniaturisation. This is the primary wavelength for direct follicle stimulation at the therapeutic depth.

940nm

940nm Deep NIR: Subcutaneous Layer and Systemic Scalp Health

940nm reaches the deepest tissue layer — the subcutaneous fat beneath the follicle. At this depth, 940nm supports scalp microcirculation, the fatty acid environment surrounding follicles, and overall tissue health in the scalp's deepest layer. Adding 940nm to the 630nm and 850nm combination creates a three-depth treatment that addresses the scalp from surface to sub-follicular tissue.

Scalp photobiomodulation for hair loss — stimulating follicle activity, extending the anagen growth phase and supporting scalp health through daily red light sessions.

The PHL Cap uses 630nm Red Light, 850nm Near-Infrared and 940nm Deep Near-Infrared across 450 LEDs for full scalp coverage.

For most red light therapy devices, sessions of 10 to 20 minutes per treatment area are the recommended starting point. The right session length depends on the device's irradiance, your distance from the device, and your treatment goal. Follow the protocol guide included with your device, and build up session time gradually if you are new to red light therapy.

Yes. Red and near-infrared light therapy at therapeutic wavelengths (600–1000nm) is non-ionising, produces no UV radiation, and carries no thermal damage risk at the power levels used in consumer devices. It is safe for daily use for most adults. Consult a healthcare provider before use if you have a light-sensitive condition, are on photosensitising medications, are pregnant, or have active cancer in the treatment area.
