Low-level laser therapy (LLLT) is a unique medical procedure that utilizes low-power lasers on the surface of the skin. By employing these low-power lasers, LLLT has demonstrated its ability to alleviate pain and enhance cellular functioning.
LLLT, an approved method by the FDA, employs laser technology to address hair loss and thinning hair concerns in both men and women. This non-invasive and painless approach utilizes light technology to stimulate hair follicles, resulting in the scientific regrowth of thicker and fuller hair.
LLLT offers an effective solution to combat hair loss and encourage hair growth. This innovative laser therapy has the potential to slow down or even halt hair loss progression. Furthermore, through consistent utilization, it has shown promising results in the growth and thickening of existing hair.
The recognition and acceptance of LLLT as a viable treatment for hair loss have evolved considerably in the past decade. Esteemed professionals specializing in hair restoration and hair transplant surgery, including globally renowned experts in the field of hair loss, have been persuaded by the compelling evidence derived from rigorous clinical trials.
Understanding the Mechanism of Low-Level Laser Therapy
To comprehend how low-level laser therapy (LLLT) operates, we turn to the Grotthuss-Draper law, the first law in photochemistry. It states that for a photochemical reaction to occur, light must be absorbed by a chemical substance.
Introducing the Key Player: Cytochrome c Oxidase
Within LLLT, the vital chemical substance involved is an enzyme called Cytochrome c oxidase. This enzyme plays a crucial role in the electron transport chain within mitochondria, the energy-producing powerhouses of cells.
The Process of Photo-Biostimulation
The phenomenon at play is known as photo-biostimulation. It begins when laser light with an optimal wavelength penetrates the skin tissue, reaching the hair follicle roots. The protons within the light stimulate the Cytochrome c oxidase enzyme, triggering an exciting reaction in the mitochondria responsible for energy production. Consequently, a series of pro-growth and follicle protective processes are set in motion.
Unveiling the Positive Outcomes
This chain of events leads to several favorable outcomes for hair health and growth:
Increased Energy Production: The mitochondria within the cells experience a boost in energy production, specifically in the form of adenosine triphosphate (ATP). This surge in energy levels contributes to the overall vitality of the hair follicles.
Modulation of Reactive Oxygen Species: The laser therapy also affects the balance of reactive oxygen species, which helps regulate the cellular environment. This modulation supports the health and functioning of the hair follicles.
Enhanced Gene Transcription: Through LLLT, there is an upregulation of gene transcription, which influences the expression of specific genes involved in hair growth and maintenance. This optimization contributes to the overall improvement of the hair follicles.
Promotion of Pro-Growth Processes: LLLT stimulates and enhances pro-growth processes within the follicular epithelium, the outer layer of the hair follicles. This stimulation helps foster a conducive environment for healthy hair growth.
The Desired Outcome
The cumulative effects of LLLT yield several positive changes:
Decreased Inflammation: The therapy aids in reducing inflammation in the scalp, providing relief to any existing inflammation that might hinder hair growth.
Reduced Impact of DHT: Dihydrotestosterone (DHT), a hormone known for its role in hair loss, has its negative effects mitigated through LLLT. This reduction in DHT’s influence helps maintain healthier hair.
Hair Thickening: LLLT contributes to hair thickening, resulting in fuller and denser-looking hair. The therapy promotes the overall thickness of individual hair strands.
Increased Growth Factors: By stimulating the necessary biological processes, LLLT encourages the release and activity of growth factors, further supporting hair growth and overall hair health.
Can Low Level Laser Therapy Really Help with Hair Loss?
Low Level Laser Therapy, commonly referred to as LLLT, is becoming an increasingly popular option for individuals experiencing mild to moderate “pattern hair loss.” This non-invasive treatment is believed to have a positive impact on blood circulation, potentially halting hair loss in approximately 85% of cases. Additionally, it shows promising results in stimulating new hair growth in about 55% of cases, as documented in various medical sources.
It is important to note that responses to laser therapy can vary significantly from person to person. While the majority of individuals may experience positive outcomes, it is not a guaranteed solution for everyone. Each person’s unique circumstances and characteristics play a role in determining the effectiveness of LLLT.
It is worth mentioning that the results obtained from laser therapy can be inconsistent. The medical community has reached a consensus that LLLT appears to work for a significant portion of individuals, but it may not deliver the desired outcomes for all. Several factors may contribute to this disparity, such as an individual’s overall health, the progression and type of hair loss, dietary habits, lifestyle choices, and genetic predisposition.
Exploring Options for Treating Hair Loss
When it comes to combating hair loss, there are two primary options available that utilize low level laser therapy. Although these options have the same ultimate goal of slowing down or stopping hair loss while promoting the growth of healthy hair, they differ in their approach and accessibility.
1. Visiting a Hair Loss Clinic
One option is to seek treatment at a hair loss clinic. These clinics offer in-clinic laser therapy for hair loss, which involves regular visits to the clinic, typically 2-3 times per week, over a period of up to 12 months. During these sessions, individuals sit beneath a dome that emits light onto the scalp, aiding in strengthening and stimulating hair growth. Each treatment session lasts approximately 30-40 minutes.
Challenges of In-Clinic Treatments
While in-clinic treatments can be effective, there are certain drawbacks associated with them. Firstly, the cost of these treatments can be substantial. Additionally, the need to visit the clinic multiple times per week for an extended period of time can be inconvenient for many individuals. Another concern is that the laser machines used in these clinics may be outdated and of lower quality compared to the modern at-home laser devices available today.
2. At-Home Products
Fortunately, advancements in technology have led to the emergence of more convenient and preferred alternatives for hair loss treatment. At-home low level laser therapy devices have gained popularity in the market, making traditional hair loss clinic laser machines less common.
