Restore Your ConfidenceHow Solis Red Light Therapy Transforms Hair Loss
Unlike topical treatments that struggle to penetrate beyond the scalp surface, Solis red light therapy effectively reaches 2-3mm below the epidermis to the critical dermal papilla and hair bulb. Our carefully selected 630nm/660nm red and 810nm/830nm near-infrared wavelengths are specifically designed to target these hair-generating structures where new growth begins.
When our therapeutic wavelengths reach hair follicle cells, they interact with photoreceptors in the mitochondria, boosting cellular metabolism and energy production. This revitalisation process provides the substantial energy required for active hair growth, essentially recharging follicles that have become sluggish or dormant without relying on harsh chemicals or hormonal interventions.
Red light therapy stimulates microcirculation in the scalp, increasing blood flow to follicular regions by up to 55%. This enhanced circulation creates a nutrient-rich environment around hair follicles, delivering vital oxygen, proteins, and vitamins while efficiently removing growth-inhibiting waste products that can accumulate in the scalp.
Unlike conventional treatments that often show diminishing returns, red light therapy's benefits amplify with consistent use. Regular sessions establish healthier follicular function and improved scalp conditions, gradually extending the growth phase of more hair follicles and creating cumulative improvements in density and thickness that continue to develop over 3-6 months of use.

What else does the science say?
Recent advances in hair restoration research have strengthened the scientific foundation for red light therapy's effectiveness. Clinical studies show these specific wavelengths activate dormant hair follicles, extend the anagen (growth) phase, and improve shaft diameter through enhanced cellular metabolism. Researchers have documented significant improvements in hair count, thickness, and growth rate in both men and women. This expanding evidence base explains why trichologists and dermatologists increasingly recommend professional-grade red light therapy as an essential component of comprehensive hair restoration programs.
In a landmark double-blind trial by Lanzafame et al. (2013), men with androgenetic alopecia used a helmet of 655 nm red lasers every other day. After 16 weeks, the treated men saw a 35–39% increase in hair counts, whereas the placebo group showed virtually no change. No side effects occurred. This dramatic improvement – achieved with wavelengths in the 650–660 nm range – highlights the hair-regrowing power of the same red light used in Solis devices.

A similar randomised trial in women by Lanzafame et al. (2014) found near four-fold greater hair regrowth with 655 nm light therapy compared to placebo. After 16 weeks, hair counts increased by ~48% in the red-light group versus only ~11% in the sham group This 37% higher relative gain underscores that Solis’s red wavelengths produce significant new hair growth for females, far outpacing no treatment.

In a large multicenter trial, Jimenez et al. (2014) tested an FDA-cleared 655 nm laser comb on men and women with hereditary hair loss. After 26 weeks (3 sessions per week), laser-comb users grew ~20 more terminal hairs per cm², while the sham-device group gained under 3 hairs in that same area. This was a highly significant improvement (p<0.0001) regardless of age or sex. Moreover, treated patients noticed fuller, thicker hair. These results confirm that the wavelengths utilized in every Solis device can substantially increase hair density in real-world users.

A 17-week trial by Friedman and Schnoor (2017) evaluated a 650 nm laser cap in women with thinning hair. The results were outstanding: laser-cap users achieved a 51% increase in hair counts, far outperforming the sham group’s ~6% increase, In practical terms, the treatment group grew about 5 times more new hairs than the placebo group (approximately +64 vs +12 hairs). This remarkable difference showcases how near-650 nm red light – like that emitted by Solis devices – can dramatically boost female hair regrowth.

Barikbin et al. (2017) compared pure red vs. red-plus-infrared light for pattern hair loss. Ninety patients were randomised to 655 nm red laser only, 655 nm + 808 nm (infrared) laser, or a no-treatment control. Both light therapy groups showed significant hair density gains (~+9 hairs per cm²), whereas the untreated controls actually lost hair (about –1.8 hairs/cm²). In other words, light therapy not only stopped ongoing hair loss but promoted new growth, while those without treatment continued to thin. With no adverse effects noted, this study demonstrates that combined 655 nm red and 808 nm near-infrared wavelengths (all within the Solis range) can safely yield superior hair preservation and regrowth.

Even autoimmune hair loss can respond to light therapy. Serrano et al. (2023) reported a case of alopecia areata treated with a 660 nm red laser as stand-alone therapy. An isolated bald patch received daily red light sessions, resulting in significant regrowth of pigmented hair within 7 days. By day 21, the previously bare spot was completely filled in with normal-thickness hairs. This rapid recovery, achieved without drugs, highlights the healing capability of Solis’s 660 nm wavelength in restoring hair even for immune-related loss.

A 2023 randomized trial (HAIRLASER) shows that near-infrared light therapy can help chemotherapy survivors regrow hair faster. Breast cancer patients were assigned to no treatment vs. thrice-weekly PBM sessions (medical lasers started at end of chemo). By 1 month post-chemotherapy, the light-treated group had significant hair regrowth according to blinded scalp assessments, whereas the control group’s hair recovery stayed stagnant. Treated patients also reported better quality of life and body image as their hair returned sooner. These findings suggest that Solis’s red/NIR wavelengths (e.g. 810–830 nm range) can safely jump-start hair regrowth after chemo, improving outcomes for cancer survivors.

Red Light Therapy for Thin Hair - My Findings
I can personally attest to the hair growth benefits of red light therapy. I have been using the Solis panel for the collagen building and anti-aging effects for 5 weeks. I also decided to start using it on my hairline and top of my head... I began using it on my head 4 weeks ago. Much to my surprise, I am getting TONS of hair regrowth. The areas that were receding... are coming in like crazy!

Hair Loss Usage Guide
Optimal Positioning
Position your Solis panel 4-6 inches from your scalp for maximum follicle stimulation. For targeted treatment of specific thinning areas, hold the panel closer (4 inches) and focus directly on those regions. For whole-head coverage, place the panel 6 inches above the crown while seated, allowing the light to cascade across your entire scalp. For receding hairlines or temple regions, angle the panel slightly to ensure these critical areas receive direct light exposure.
Dosage Protocol
For hair rejuvenation, consistent 10-20 minute daily sessions yield the best results. Activate both Red (630nm/660nm) and Near-Infrared (810nm/830nm/850nm) wavelengths together—this combination optimises both surface follicle stimulation and deeper dermal papilla activation. Morning sessions fit easily into most routines, but evening treatments can be equally effective. Begin with daily sessions for the first 8-12 weeks, when most users start seeing noticeable improvements, then maintain with 3-5 weekly sessions for ongoing results.
Habit Stacking
Scalp Massage Enhancement: Perform gentle scalp massage techniques during your red light session—the dual stimulation may further enhance blood flow and nutrient delivery to follicles.
Hair Treatment Enhancement: Apply your topical hair products (serums, oils) immediately before your red light session - the increased blood flow may enhance absorption and effectiveness of your existing hair care products.
Meditation & Hair Renewal: Use your red light therapy time for a brief mindfulness practice—nourishing both your follicles and mental wellbeing simultaneously.
Remember: Hair growth is a marathon, not a sprint. Most users see initial results around 8-12 weeks, with continued improvement through 6 months of consistent use. Take monthly progress photos from consistent angles to track your transformation.
