Product Details
The StimuField® PEMF Cap is a wearable, non-invasive device that uses ICES® Pulsed Electromagnetic Field (PEMF) technology to support hair thickness, fullness, and scalp health. Developed by biomedical engineer Dr. Robert Dennis, whose ICES® PEMF technology was originally created from NASA research, in collaboration with Stimusil and Dr. Scott Gerrish, the cap delivers precisely tuned electromagnetic pulses to stimulate hair follicle stem cells at the cellular level, with no drugs, needles, or topical products required.
Designed for adults experiencing hair thinning, excessive shedding, or diminishing coverage, the cap is intended as a proactive, consistent-use wellness device.
Key Features:
ICES® PEMF Technology
Uses complex waveforms and dynamic frequencies to enhance the body’s natural ability to repair and regenerate hair follicle stem cells.
Intuitive User Interface
Single button to turn the device on and off, with automatic shut-off at the end of each session.
Washable Inner Liner
Designed for comfort and hygiene, the removable inner liner is fully washable, so patients can keep the device fresh anytime.
Long-Lasting Battery
Up to 2 weeks of daily use on a single charge.
Discreet, Everyday-Comfort Design
Under 0.5 inches thick and styled like a standard baseball cap, so it can be worn
How It Works
PEMF therapy uses low-intensity electromagnetic pulses to stimulate microcirculation and cellular repair processes in the scalp. StimuField’s ICES® technology uses complex, dynamic waveforms designed to enhance the body’s natural ability to repair and regenerate hair follicle stem cells while avoiding cellular habituation to the stimulation.
The cap’s multi-coil array is built into a breathable, cushioned liner, delivering overlapping electromagnetic fields across the scalp for full coverage. There’s no heat nor sensation, just a pure invisible energy. The device is suitable for all hair types and skin colors.
Clinical Evidence
In a 24-week pilot clinical study of healthy men and women experiencing hair thinning, daily StimuField use was associated with an average of 23 new hairs per cm2 and an 18% increase in hair density, alongside reduced shedding and increased hair volume, with minimal reported side effects such as mild itchiness or Dandruff.
Usage Protocol
Session length: 30 minutes per day
Onset of effect: Reduced shedding often begins within the first 4 weeks
Visible results: Typically appear between 3-6 months of consistent daily use
Operation: Press and hold the button for 3 seconds to power on and start the session, the cap automatically shuts off after 30 minutes; no app or smartphone required
Exceeding the recommended frequency or duration does not improve results and is not advised.
Product Overview
Available in two sizes to accommodate a range of head circumferences:
L: fits up to 22.5″ (57 cm)
XL: fits up to 24″ (61 cm), aligned with standard commercial cap sizing
Premium adjustable strap on both sizes for a personalized fit
Less than 0.5 inches thick, cordless, and discreet under everyday wear
Safety
The device is CE-marked and FCC compliant, and independently tested for safety, using low-intensity PEMF technology. The device is not recommended for users who: Have a pacemaker, defibrillator, or other implanted medical device Have a head implant made from magnetic or metallic materials. Are pregnant, nursing, undergoing cancer treatment, or have a diagnosed neurological condition. Have experienced a stroke or brain bleed. Have recently had or are planning surgery or a laser/cosmetic procedure
The device comes with several safety features such as battery temperaturecontrol and automatic session shut-off.
Ideal Candidate Profile
Adults with early-to-moderate hair thinning, diffuse shedding, or reduced density
Patients seeking a non-invasive, drug-free complement to existing treatments (e.g., PRP, minoxidil, FUE aftercare)
Not indicated for fully bald areas with no viable follicles
