Low level laser therapy (LLLT) has been increasingly used worldwide for the treatment of Androgenetic alopecia and other forms of hair loss. Low level laser therapy (LLLT) is one of the very few non surgical modality of hair loss treatment approved by the US FDA (2007). The lasers used in LLLT are typically small (often handheld) units, and unlike surgical and aesthetic lasers, do not heat the targeted tissue. Instead, LLLT emits low levels of light that are absorbed by your mitochondria (the energy-producing organelles in many of your cells), which then can increase cellular energy production and ultimately help heal surrounding tissue. This process is comparable to plant photosynthesis, during which sunlight is absorbed by plants and converted to energy for the plants to grow.
