For the past six months, journalist Braelyn Wood has been testing the HigherDose Red Light Showerhead Filter, a device that combines a water filtration system with red light therapy. The product, which launched last year, retails for $599 and is designed to fit into a daily shower routine without adding extra steps.
The showerhead features a 10-stage filtration system that reduces contaminants such as chlorine, heavy metals like lead and mercury, volatile organic compounds, microplastics, and mineral residue. It also includes a detachable red light ring that emits dual wavelengths of 650 nanometers red and 850 nanometers near-infrared light. The company says the device delivers 200 milliwatts per square centimeter of light energy from head to toe during a shower.
According to Wood, the red light component can be removed from the showerhead entirely. The charging dock doubles as a stand, allowing the ring to be used as a standalone red light device anywhere in the home. The product is available in three finishes.
Wood reported that installation took less than 10 minutes. The kit includes the showerhead, red light ring, charging dock, charging adapter and cable, a wrench, plumber’s tape, and a manual. A remote control allows users to set a timer for 5, 10, or 15 minutes for a red light session. The battery lasts about a month before needing a recharge, and the light connects to the showerhead with a turn-and-lock system that can be easily disconnected. Filter replacement is recommended every 75 days at a cost of $45 per filter, totaling about $180 per year.
Skin and Hair Changes
Wood noticed several changes in her skin and hair after regular use of the device. She observed that her skin appeared more radiant and less prone to breakouts. During a trip to Europe, where she did not have access to the filter, she experienced dry, tight skin and breakouts along her T-zone, including blackheads and whiteheads. She attributed the difference to the absence of the shower filter.
A 2024 dermatology review cited by Wood indicates that photobiomodulation, the mechanism behind red light therapy, can promote skin rejuvenation and reduce acne. She also noted that hard water, which is high in calcium and magnesium, can interact with soap to form a residue that clogs pores and prevents moisture absorption, leading to dry skin and pimples.
Wood also reported improvements in her hair health. During her trip to Europe, her hair became dry and brittle. After returning home and resuming use of the filter, her hair felt softer within a week. She noted that despite being overdue for a haircut by five months, hair stylists told her that her long strands appeared healthy.
A 2021 study found that 650 nanometer red light promoted the growth of human hair follicles and delayed the transition from the growth phase to the shedding phase in laboratory tests. The near-infrared wavelength at 850 nanometers penetrates deeper into the scalp to support circulation, which is important for follicle health. Filtered water free of chlorine and mineral buildup also contributes to a healthier scalp environment.
Mood and Calm
Wood expressed caution about claims that the device elevates mood. The product page suggests red light can improve mood, and emerging research on photobiomodulation indicates effects on the nervous system and circadian rhythm. A 2025 systematic review on the topic is referenced but not detailed in the source material.
Wood concluded that the device is worth the investment, especially for those who have struggled to maintain a consistent red light therapy routine. She noted that the filter adds no extra time or stress to her daily routine. A discount code is available for $90 off the purchase price.
