GlossaryIncandescent Light

light produced by heating a filament until it glows

Incandescent light refers to a type of lighting produced by an incandescent lamp or bulb, which generates light by heating a filament wire to a high temperature until it glows. This process involves passing an electric current through the filament, typically made of tungsten, enclosed in a glass bulb filled with an inert gas to prevent oxidation. While incandescent lights are known for their warm, natural light quality, they are less energy-efficient compared to modern lighting technologies like LEDs and fluorescent lamps.

community 4 years on finasteride and Minoxidil with great success. Ask me stuff!

in Progress Pictures 950 upvotes 3 years ago

. ummwhatsure: No it doesn't. I started losing my hair around 27/28. This user has had great success with a combination of finasteride and Minoxidil, taking 1 milligram of finasteride per day and applying Minoxidil twice daily for 4 years, starting when they were 31. They experienced some shedding in the first two years, but now have thicker, fuller hair than before.
