"LLLT triggers biostimulative-regenerative processes inside the cell and subsequently causes revitalisation of the issue as well. Second effect of LLLT refers to the vasodilatation and neovascularisation of local blood and lymph vessels, thus causing a better removal of waste products and, on the other hand, improved oxygenation and nutrition of damaged tissue. Analgesic and anti-inflammatory effects of LLLT are also significant when irradiating certain dermatological changes." 1Zlatko Simunovic, M.D., F.M.H., 2Tatjana Trobonjaca, M.D. 1Pain Clinic-Laser Center, Locarno, Switzerland 2Laser Center, Opatija, Croatia
A 1986 paper on LLLT by the International Laser Group Association states "..... it normalisers metabolism of tissues, improves blood cell nutrition, and assures a regular sebaceous secretion .... if we start from a normal quantity of hair bulbs per square cm of the various subjects involved, we can state that there was strengthening of hair bulbs ..... hair growth could be actually ascertained - also it being darker than before".
