Hair loss stemming from different types of alopecia, such as androgenic alopecia and alopecia areata, negatively affects over half the population and, in many circumstances, causes serious psychosocial distress. Current treatment options for alopecia, such as minoxidil, anthralin, and intralesional corticosteroids, vary efficacy and side effect profiles. It is known that low-level laser/light therapies (LLLT), or photobiomodulations, such as the US FDA-cleared HairMax Lasercomb®, He-Ne laser, and excimer laser, are relatively affordable, user-friendly, safe, and effective forms of treatment for hair loss...

Background In a retrospective study, the success rates of laserdacryoplasty using a diode laser were defined and compared to success rates using an erbium : YAG laser. Using a diode laser at a wave length of 980 nm, thermal destruction of tissue leads to recanalization. Using an erbium : YAG laser at a wave length of 2940 nm, recanalization of punctual stenosis is achieved by formation of a cavitation bubble in a closed system. Materials and Methods 94 patients (64 women, 30 men, mean age 60.8 years) with 107 absolute lacrimal duct stenoses who were treated by laserdacryoplasty using a diode laser were included in a retrospective study...
