Selenium has been used since the 1960s in dandruff shampoos and topical medications for such skin disorders as folliculitis ("hot tub" syndrome) and tinea versicolor, a mild infection of the skin caused by the yeast-like fungus Pityrosporum
Can selenium sulfide be used in treatment for lice?
Selenium sulfide is used against tinea capitis.
The selenium cell was used in an optical telephone developed by Alexander Graham Bell in 1879
Selenium does not directly interact with light. However, selenium is used in the production of photocells, which convert light energy into electrical energy. Selenium can also be used in some photovoltaic applications to generate electricity from sunlight.

To make a copy ,the image of the material to be copied is projected onto the selenium coated surface.
In the past, selenium was mainly used in the production of glass to remove color caused by impurities and to make glass more transparent. It was also employed in photographic paper to increase sensitivity to light. Additionally, selenium was used in early electronics as a rectifying agent in devices like rectifiers and photovoltaic cells.
The element Selenium is very poisonous, yet your body needs tiny amount of it to be healthy. Most commonly, selenium is found in dandruff shampoos.
The property of selenium used in photocopiers and laser printers is its photoconductivity. Selenium becomes more conductive when light is shone on it, allowing images to be formed and transferred onto paper in these devices.
The chief commercial uses for selenium today are in glassmaking and in pigments. Selenium is a semiconductor and is used in photocells. Uses in electronics, once important, have been mostly supplanted by silicon semiconductor devices. Selenium continues to be used in a few types of DC power surge protectors and one type of fluorescent quantum dot.
Se4Br7 is the chemical formula for selenium tetrabromide. It is a compound composed of selenium and bromine atoms, with four selenium atoms and seven bromine atoms in each molecule. Selenium tetrabromide is a red-brown solid that is primarily used in chemical synthesis.
Clinics in Dermatology was created in 1983.
