Low-Level Laser Therapy for Regrowth in Hair Treatment

Low-Level Laser Therapy (LLLT) is a non-invasive treatment that uses low-intensity light to stimulate hair growth. It works on the principle of photobiomodulation, where laser light penetrates the scalp to promote cellular activity within hair follicles. This process enhances blood flow, increases cellular metabolism, and reduces inflammation, creating an optimal environment for hair regrowth. LLLT is primarily used for treating androgenetic alopecia (male and female pattern hair loss), but it has also shown potential in managing other types of hair loss, including telogen effluvium and alopecia areata.

The mechanism of LLLT involves the use of red or near-infrared light, typically within the 600-1100 nanometre wavelength range. The light energy is absorbed by cytochrome c oxidase within the mitochondria, boosting adenosine triphosphate (ATP) production. This biochemical change promotes hair follicle activity, encouraging the transition of hair follicles from the telogen (resting) phase to the anagen (growth) phase.

Clinical Evidence Supporting LLLT

Several studies have evaluated the efficacy of LLLT in promoting hair regrowth. A 2017 meta-analysis published in the Journal of the American Academy of Dermatology reviewed clinical trials on LLLT for androgenetic alopecia. The results showed significant increases in hair density and thickness in patients using LLLT compared to placebo groups .

Another randomised controlled trial, published in the International Journal of Trichology, examined the use of LLLT in both men and women with pattern hair loss. The study demonstrated a 35% increase in hair density after 16 weeks of treatment, highlighting LLLT as a viable option for hair restoration without significant side effects.

How LLLT Compares to Other Hair Loss Treatments

LLLT offers a non-invasive alternative to pharmacological treatments like finasteride and topical minoxidil, which can have potential side effects such as hormonal changes or skin irritation. Unlike surgical options, including Follicular Unit Extraction (FUE) hair transplants, LLLT does not involve recovery time or surgical risks. However, the results of LLLT may not be as dramatic as those achieved with a hair transplant, particularly in advanced hair loss cases where follicular damage is extensive.

Who Can Benefit from LLLT?

LLLT is most effective in the early stages of hair loss when the follicles are still active but underperforming. Patients with widespread or advanced hair loss may find that LLLT alone is insufficient and may benefit from a combination of treatments, including FUE hair transplantation. At My Hair UK, we often recommend a tailored approach, integrating LLLT as part of a holistic hair restoration plan that aligns with each patient’s specific needs.

Cost of Hair Transplant vs LLLT

The cost of a hair transplant at My Hair UK depends on the number of grafts required. Prices typically range from £3,000 to £7,000, offering a permanent solution to hair loss. LLLT, on the other hand, involves an ongoing cost as it requires repeated sessions or investment in a home-use laser device, which can cost anywhere from £500 to £2,000.

When considering treatment options, it is important to weigh the cost against the potential benefits. While LLLT may appear more affordable initially, its long-term costs can accumulate, especially if ongoing treatment is required to maintain results. For those seeking a more definitive solution, a hair transplant may provide better value over time.

What to Expect from LLLT Treatment

During LLLT sessions, patients typically wear a cap or use a handheld device emitting laser light. Each session lasts around 20 to 30 minutes, with treatments recommended two to three times per week. Most patients begin to see visible results after three to six months of consistent use. The treatment is painless, and there are no known severe side effects, making it a safe option for most individuals.
