The iGrow is one of the most powerful hair growth systems developed for home use, and has an equivalent output to most in-office hair lasers. Furthermore, the iGrow’s patented headphone design maintains a fixed distance of 3cm from the scalp. In addition, the iGrow® can be used conveniently at home, the office, or any convenient location-while listening to your favorite music on your iPod® or MP3 player.
