What is Low level laser therapy and why is it used ?

Low-level laser therapy (LLLT) , also known as laser hair therapy or cold laser therapy, is a non-invasive treatment method that uses low-energy laser light to stimulate hair growth and improve the health of hair follicles. It involves the use of red or near-infrared light wavelengths, typically emitted by a device such as a laser cap, laser comb, or laser helmet.

LLLT is used primarily for the treatment of androgenetic alopecia (male or female pattern baldness) and other forms of hair loss. The specific mechanisms of action of LLLT are not yet fully understood, but it is believed to work through several potential mechanisms:

Increased blood flow: LLLT may improve blood circulation in the scalp, delivering more oxygen and nutrients to the hair follicles, which can promote hair growth and improve follicular health.
Stimulation of hair follicles: The laser light energy is absorbed by the hair follicles, potentially stimulating cellular metabolism and promoting the production of ATP (adenosine triphosphate), which is crucial for cellular function and hair growth.
Reduction of inflammation: LLLT may have anti-inflammatory effects, helping to reduce scalp inflammation, which can contribute to hair loss.
Prolonging the anagen (growth) phase: LLLT has been suggested to prolong the active growth phase of the hair follicles (anagen phase), resulting in longer and thicker hair strands.

LLLT is typically performed in a clinic setting, but there are also portable devices available for home use. Treatment sessions are usually scheduled multiple times per week and can vary in duration. It’s important to note that LLLT may require ongoing maintenance treatments to maintain the results.

While LLLT has shown promise in stimulating hair growth and improving the density and quality of hair, its effectiveness can vary among individuals. It is generally considered a low-risk treatment with minimal side effects, but it may not be suitable for everyone. Consulting with a healthcare professional or a dermatologist specializing in hair loss can help determine if LLLT is a suitable option for your specific condition and provide guidance on the most appropriate treatment approach.
