Before hair removal, stretch your beard or shave your beard and shine light to remove it. The effect is the same whether you stretch or shave your beard. You haven't pulled your beard, right? Hair removal on the beard is ineffective without hair roots. If you have removed the beard, grow the beard and then shave with "Regenerate the roots of the hair". Pain depends on the type of treatment. Laser, light, needle, etc. Simply put, the laser feels like a rubber band. Light is less than half the pain of a laser. Needles are more painful than lasers. There is hair loss, but I can't say anything at some stores, but at my house I have to go 18,20 courses for over a year. You can search online to find the number of answers you need.
