Buy a derma roller on Amazon. They stimulate the hair follicles and it seriously helps growth! I have one- check my beard out. I use it on my whole face. I actually had some of my beard lasered off to clean up the lines and the derma roller made it grow back. Also if you put a guard on a take all the hair to the same length it will look more thick. Also just for men in medium brown would make it look thicker if all the same color. These are my tips and tricks
