I bought a very simple 5mw line generating red laser with a power supply from a company that imports laser diodes from Asia. Cost is about $15. You know what? This works way better than the magpulser which I've had and used for a bout a year and not really seen any significant change in my hair. After two 20min session with the laser my 42yr old limp lifeless looking hair now seems like it has come back to life. The shafts look thicker, stronger, more lusterous, and stand up straighter than they have in years. Also used it on my 15yr old dog who now looks like he has puppy hair coming in on his coat (Bichon Frise). I am not selling anything and you can buy these from any laser diode supply house. Here is where I got mine though: http://mfgcn.com/_wsn/page5.html I am totally convinced these things work based on scientific evidence that lasers in the 635-670nm range stimulate ATP and other growth hormones on a cellular level. So you can use these all over the body to heal, stimulate growth, strengthen immune system, and the list goes on. Star Trek was right with the pulsing laser (phaser?), remember the wand "Bones" used to heal people in "sick bay"? Today it is a reality. These lasers diodes are now available to everyone and are cheap! Only caution is be careful not to shine directly into your eyes as they are very bright. Check it out.
