How does Laser Light Help Hair Growth?
Snappy Summary of This Article
- Boosts Blood Circulation: Laser light stimulates blood flow, nourishing hair follicles for healthier, thicker growth.
- Promotes Cell Regeneration: It accelerates cell renewal, rejuvenating scalp tissues and encouraging stronger hair strands.
- Increases Hair Density: Regular laser treatments can lead to fuller, denser hair by enhancing follicle activity.
- Reduces Hair Loss: Laser light therapy can slow down hair thinning by strengthening existing hair and supporting regrowth.
- Safe and Painless: This non-invasive treatment is comfortable, with no downtime or significant side effects.
- Enhances Hair Care Results: Laser therapy complements other hair growth treatments, boosting their effectiveness.
Introduction
Low-level laser therapy (LLLT), also known as photobiomodulation, has gained attention as a non-invasive method for stimulating hair growth by targeting cellular mechanisms in hair follicles, enhancing blood flow, and activating growth pathways. According to Healthline, this therapy, which varies in effectiveness among individuals, is supported by a range of laser devices and can be used synergistically with hair transplants to improve outcomes, with several providers offering these treatments in Singapore.
Mechanisms of Photobiomodulation in Hair Follicles
Photobiomodulation (PBM) stimulates hair growth through multiple mechanisms at the cellular level. The primary target appears to be cytochrome c oxidase in the mitochondrial electron transport chain, leading to increased ATP production and cellular energy. This boost in energy metabolism activates hair follicle stem cells and promotes their proliferation. PBM also generates low levels of reactive oxygen species (ROS), which activate the PI3K/AKT/GSK-3β signaling pathway. This pathway inhibits the degradation of β-catenin, a key protein in hair follicle stem cell activation and hair cycle progression.
Additionally, PBM enhances blood flow and oxygenation in the scalp, supporting follicular health. It stimulates the production and secretion of growth factors like WNTs from skin-derived precursor cells, which further activate β-catenin signaling in hair follicle stem cells. These combined effects push dormant follicles into the active growth (anagen) phase of the hair cycle. The optimal wavelengths for these effects appear to be in the red and near-infrared spectrum, typically between 630-660 nm and 810-850 nm. While individual responses can vary, these mechanisms collectively contribute to PBM’s ability to promote hair regrowth in conditions like androgenetic alopecia.
Comparative Analysis of Laser Devices for Hair Growth
Laser hair growth devices vary in design, power output, and treatment protocols, offering different options for addressing hair loss. The iRestore Professional 282 utilizes 282 lasers and LEDs, delivering 1,410 mW of power output in 25-minute sessions every other day. In contrast, the HairMax Ultima 9 LaserComb features 9 laser diodes for targeted treatment, allowing for more precise application to specific areas like the hairline. The Capillus ONE Hair Growth Laser Cap offers the shortest treatment time at just 6 minutes daily. Clinical studies have shown promising results for these devices, with the HairMax LaserComb demonstrating a significant increase of 19.8 hairs/cm² in mean terminal hair count over 26 weeks compared to a sham device. When choosing a device, factors to consider include treatment time, ease of use, and coverage area. While helmets like the iRestore provide full scalp coverage, handheld devices like the HairMax comb offer greater flexibility for targeted treatment. It’s important to note that results can vary, and consistent use over several months is typically required to see noticeable improvements in hair growth.
Synergistic Effects of Laser Therapy and Hair Transplants
Laser therapy can significantly enhance the effectiveness of hair transplant procedures, offering a synergistic approach to hair restoration. When used before a hair transplant, low-level laser therapy (LLLT) helps prepare the scalp by improving blood circulation and stimulating existing hair follicles, creating an optimal environment for transplanted grafts. Post-transplant, LLLT promotes healing, improves blood flow, and enhances the growth of both transplanted and existing hair. This combination approach has shown promising results, with laser therapy potentially increasing the success rate of hair transplants and accelerating the regrowth process. Additionally, some studies suggest that combining LLLT with other treatments like minoxidil and finasteride may produce even better outcomes, acting synergistically to enhance hair growth. While more research is needed to fully understand the long-term effects, the integration of laser therapy with hair transplantation appears to offer a comprehensive solution for those seeking to address hair loss.
Singapore LLLT Providers
In Singapore, several clinics and aesthetic centers offer Low-Level Laser Therapy (LLLT) for hair growth.
- Wellaholic is a notable provider, offering LLLT treatments as part of their comprehensive hair restoration services.
- Dr Tyng Tan Aesthetics and Hair Clinic is another option, providing LLLT using medical-grade lasers with stronger intensity for potentially faster results and wider scalp coverage.
- Sozo Clinic offers the iGrow® home hair laser device, which provides full scalp coverage and is hands-free, making it convenient for at-home use.
- For those seeking in-clinic treatments, Freia Medical offers the Revage 670 Hair Biostimulation laser system, which uses 30 laser diodes rotating around the scalp to stimulate blood flow to thinning hair follicles.
These providers offer various LLLT options, allowing patients to choose based on their preferences for in-clinic or at-home treatments, treatment frequency, and specific hair loss concerns.
