Stimulix
improvement in 7 minutes
Stimulix combines a 360° helmet with tri-spectrum medical LEDs (660 / 850 / 415 nm), a gentle pulsed electromagnetic field (PEMF) module and a photo-activating serum to
stimulate growth, thicken the fiber and purify the scalp — no surgery, no pain,
through photobiomodulation (PBM, formerly LLLT) and low-intensity electromagnetic stimulation. The protocol is designed to reactivate follicular metabolism,
improve scalp microcirculation and support a denser, healthier-looking hair cycle in short, repeatable sessions.
+15 to +39 % density in 12–26 weeks*
+10 to +18 % fiber thickness
3 sessions per week, 7 minutes
PEMF low-intensity electromagnetic stimulation
*Indicative results based on photobiomodulation literature and combined use of red / NIR / blue light
with topical actives. To be confirmed by clinical studies.
Stimulix is a wellness and cosmetic device concept. It is not a medical treatment for alopecia, and results may vary depending on
alopecia stage, age, adherence and scalp condition. Consult a dermatologist in case of pathological hair loss.

The science behind Stimulix
The system is based on photobiomodulation (PBM, formerly LLLT): red and near-infrared photons are
absorbed by cytochrome c oxidase (complex IV of the mitochondrial respiratory chain), which releases
nitric oxide (NO), increases ATP production and modulates reactive oxygen species (ROS). Result: follicles
exit the telogen phase, the anagen phase is extended and the scalp microenvironment is purified.
Each wavelength has a specific function.
Red spectrum • 630–680 nm
Energy boost for growth
Red light penetrates the superficial dermis (≈3–5 mm). Absorbed by cytochrome c oxidase, it
dissociates inhibitory NO, restores electron transport and increases ATP synthesis. This awakens
bulge stem cells (LGR5+, K15+), activates the Wnt/β-catenin pathway and extends the anagen phase.
Cytochrome c oxidaseATP ↑Wnt/β-cateninProlonged anagen
Near infrared • 810–850 nm
Deep action & anti-inflammatory
NIR reaches the dermal papilla (≈5–10 mm) through a favorable optical tissue window.
It reduces pro-inflammatory cytokines (TNF-α, IL-6), inhibits local 5-α-reductase, improves
microcirculation and stimulates papillary dermal cells that produce VEGF and IGF-1.
VEGF ↑IGF-1 ↑TNF-α ↓Microcirculation
Blue spectrum • 415 nm
Microbiome & sebum under control
Blue light targets endogenous porphyrins produced by Cutibacterium acnes and
Malassezia spp. on the scalp. The excitation generates localized singlet oxygen that reduces
bacterial load, regulates sebum secretion and limits seborrheic dermatitis and dandruff. Its contribution to visible regrowth is
mainly indirect, by improving scalp health rather than directly driving follicular density.
PorphyrinsC. acnes ↓Malassezia ↓Sebum regulated
Laser stimulation • 650 nm
Low-level laser therapy (LLLT)
LLLT uses coherent red light from diode lasers (typically 650 nm) to stimulate hair follicles. The laser energy is absorbed by cytochrome c oxidase, increasing ATP production and cellular activity. This panel summarizes adjacent literature; the Stimulix prototype itself uses LEDs rather than onboard laser emitters.
Coherent red laserATP ↑Anagen ↑Clinically proven
Cellular mechanisms & dosimetry
The efficacy of photobiomodulation follows a biphasic response (Arndt-Schulz law): too little light
activates nothing, too much light inhibits. Stimulix targets the therapeutic window described in the literature.
Simplified cascade: light reaches the mitochondria through skin and scalp, releases the inhibitory NO
bound to cytochrome c oxidase, restores ATP production and triggers pro-regenerative signaling toward the follicle.
Approximate penetration depth in soft tissues, per Anderson & Parrish (1981) and Avci (2014).
Triggered biological cascade
Absorption: photons 630–850 nm captured by cytochrome c oxidase (CcO, complex IV).
NO release: photodissociation of inhibitory NO bound to CcO.
↑ ATP & ↑ ROS: restoration of mitochondrial respiration and redox signaling.
Transcriptional activation: NF-κB, AP-1, HIF-1α, Wnt/β-catenin and Shh pathways.
Bulge stem cells: proliferation of LGR5+/K15+ cells → new anagen phase.
Dermal papilla: secretion of VEGF, IGF-1, KGF → fiber thickening.
Anti-inflammation: reduction of TNF-α, IL-1β, IL-6 and partial inhibition of 5-α-reductase.
Irradiance target: 8–20 mW/cm² at scalp contact, to be confirmed on the final product by spectrometric measurements.
Fluence target per session: 3–7 J/cm², within the therapeutic window described by Hamblin et al., pending final validation.
Duration: 7–15 min, 3 times/week for a minimum of 12 weeks.
Contact temperature: < 40 °C, monitored by NTC sensors + automatic shutoff.
Eye safety: compliant with IEC 62471 (risk group 1, exempt).
Coherence: non-coherent LEDs — equivalent efficacy to laser for PBM (Karu, 2010).
Hair regrowth physiology: 3 major activation pathways
The light architecture of Stimulix does more than heat the dermis. It induces precise photochemical reactions at the core of dormant hair follicles (telogen phase).
1. Cytochrome c Oxidase Pathway (CcO)
By absorbing red (660 nm) and near-infrared (850 nm) photons, the CcO (complex IV of the mitochondrial chain) releases the nitric oxide (NO) that was blocking it. Oxygen can bind again, massively restarting ATP synthesis. The highly energy-demanding dermal papilla cells regain the fuel needed to produce keratin.
2. Wnt / β-catenin Activation
Photobiomodulation transiently modifies the redox signal (physiological ROS), activating proliferation of stem cells housed in the bulge. Activation of the Wnt/β-catenin pathway forces follicles to switch from their resting phase to a new hair growth phase (anagen).
3. Vascular Network (VEGF)
Nitric oxide (NO) released by mitochondria also acts as a local vasodilator. In parallel, PBM stimulates the cellular machinery to produce VEGF growth factor, increasing micro-angiogenesis. The hair bulb is then massively supplied with organic nutrients.
Level of evidence

Synergy & Medical Treatments
The local action of photobiomodulation is an ideal complement to approved medical treatments (pharmacology) for androgenetic alopecia.
Minoxidil (Topical / Oral)
Action: Peripheral vasodilator, it prolongs the anagen phase (growth) and delays the telogen phase.
PBM Synergy: Red light increases micro-circulation and skin permeability, allowing better absorption of the lotion. Apply topical Minoxidil only after the helmet session, on a fully dry scalp.
⚠️ Caution — Sebo-Control + topical Minoxidil: Sebo-Control contains salicylic acid (2 %, keratolytic) and essential oils (tea tree, lemon) that transiently reduce skin barrier function. Topical Minoxidil, typically formulated with propylene glycol (already an irritant), applied on a freshly exfoliated scalp significantly raises the risk of contact dermatitis. Do not apply topical Minoxidil within 8 hours of Sebo-Control use. Use on separate days. Oral Minoxidil is not subject to this restriction. Consult your dermatologist if combining both.
Finasteride / Dutasteride
Action: 5-alpha reductase inhibitors. They block the conversion of Testosterone to DHT (responsible for follicular miniaturization).
PBM Synergy: Two-level biochemical action. The drug stops the hormonal trigger (DHT) while the helmet restarts the energy machinery (ATP) to thicken the saved hair.
PRP & Hair transplant
Action: Injection of platelet-rich plasma to stimulate stem cells, or extraction surgery (FUE/FUT).
PBM Synergy: The anti-inflammatory effect of post-operative PBM considerably accelerates tissue healing, reduces redness and boosts the survival of transplanted grafts.
Positioning & use cases
Stimulix is positioned as a non-invasive hair regeneration technology, at the intersection of
advanced cosmetics, medical light and connected devices.
Target
End users
Men 25–55 with early-stage alopecia, post-partum women, people prone to seasonal hair loss or irritated scalp, helmet and PPE wearers.
Stimulix Pro (720° high-density LED helmet), Stimulix Pocket (beard & temples), Stimulix Clinic (high-power version for
professionals).
Target alopecia stages
PBM reactivates dormant or miniaturized follicles — it cannot regenerate follicles that are fully and permanently destroyed. Early to moderate stages offer the greatest benefit potential. A dermatologist consultation is recommended to confirm staging before starting.
Men — Norwood-Hamilton scale
Stages I → IV ✓ V–VI ◑ VII ✗
Stages I–IV (early to moderate recession / vertex): optimal target — follicles are miniaturized but viable. Stages V–VI: limited results expected. Stage VII (complete crown loss): not recommended — irreversible follicular destruction.
Women — Ludwig scale
Ludwig I – II ✓ III ◑
Ludwig I (mild diffuse thinning at crown) and II (moderate): primary target, best expected response. Ludwig III (severe diffuse loss, visible scalp): limited benefit. Post-partum telogen effluvium also responds well at any stage.
Key principle
Earlier = better
PBM efficacy is directly linked to residual follicle viability. The sooner treatment begins in the hair cycle decline, the greater the potential response. Hair trichoscopy is the recommended staging tool.

Guide & Usage Procedures
To ensure optimal clinical results and the longevity of your device, strictly follow this daily protocol and maintenance instructions.
1
Scalp preparation
If using Sebo-Control serum, apply it the evening before (D1, D3, D5). The next morning, on dry (or damp but towel-dried) hair, apply 2 to 3 drops of Photo-activating serum with protective actives before the photobiomodulation session.
2
Helmet placement
Place the Stimulix 360° helmet on your head. Adjust the occipital dial (head circumference 52–62 cm). The medical silicone micro-studs should be in gentle contact with the scalp to effectively part the hair.
3
Irradiation & Safety
Start your program (e.g. Boost mode, 7min) via the button or the app. The 150 medical-grade LEDs deliver the calibrated dose (3–7 J/cm²). The device monitors temperature and automatically shuts off once the irradiation cycle is complete. Avoid looking directly at the LEDs.

Wireless 360° helmet in ABS + medical silicone, 450 g. The PEMF module uses a low-voltage pulsed-current stage
to drive an external coil, generating a low-intensity time-varying magnetic field. In the device architecture, a
microcontroller sends a PWM signal to a MOSFET driver, which switches the coil in controlled pulses intended to
support local comfort, scalp microcirculation and repeatable contact conditions during the session.

Frequently asked questions
Answers to the most common questions about Stimulix.
PBM technology (or LLLT for Low Level Laser Therapy) is non-invasive, emits no harmful heat, and has no mutagenic effects (no UV). Stimulix is designed according to strict aesthetic/medical device standards. Under normal use, eye exposure remains within IEC 62471 guidance and users should simply avoid staring directly into the LEDs. There are no major side effects reported in the PBM literature. You may feel slight tingling or a very gentle warmth sensation due to increased microcirculation.
From 4 to 8 weeks, many users first notice better scalp balance (less dandruff, less inflammation, reduced sebum) and reduced shedding. More visible density changes usually require 12+ weeks and can extend to 3 to 6 months depending on alopecia stage, age, adherence and baseline scalp health. Be consistent.
Yes, transient shedding can occur at the start. As with other follicle-stimulation approaches, dormant telogen hairs may be released before a new cycle starts. This phase is usually short-lived (often 2 to 4 weeks) and does not necessarily indicate treatment failure.
Yes, it can generally be combined with Minoxidil, nutritional support or physician-prescribed Finasteride. PBM may complement these approaches, but the exact magnitude of synergy varies by user and protocol. Apply topical Minoxidil only once the scalp is fully dry, after the PBM session, to avoid interfering with light penetration.
⚠️ Important — Sebo-Control + topical Minoxidil: Sebo-Control contains salicylic acid (2 %) and essential oils (tea tree, lemon) that temporarily compromise the skin barrier. Topical Minoxidil (typically propylene glycol-based, already irritating) applied on a freshly exfoliated scalp significantly raises the risk of contact dermatitis. Maintain at least an 8-hour gap, or use Sebo-Control and Minoxidil on alternating days. Oral Minoxidil does not present this interaction. Consult your dermatologist when combining multiple actives.
As a precaution, do not use the device on active scalp lesions, known scalp cancer history, marked drug-induced photosensitivity or acute inflammatory flare-ups. Pregnancy and breastfeeding should be discussed with a physician first, even though PBM is generally well tolerated.
Try not to interrupt the protocol for more than 2 weeks during the first months if you want to maintain momentum. The device battery covers about 10 cycles, which makes travel use easier without requiring a power adapter for short trips.
We offer an extended 1-year manufacturer warranty on electronic components and LED arrays (50,000 hours lifespan). Good news: unlike depilatory or depigmenting lasers, red PBM (650nm) works safely regardless of melanin levels across phototypes I to VI.
Hair scan images and progress data are intended to be processed with privacy-by-design principles. For European commercialization, data handling is expected to follow GDPR requirements, with user consent, secure storage and export/delete controls in the final app release.
