iRestore Laser Hair Growth Helmet. iRestore has been clinically studied by doctors and has been proven to promote hair growth for men and women in a recent 2017 research study. In this clinical study, an astonishing 100% of active male and female users saw visible hair growth with an average increase of 43.2% in hair count. I bought this helmet for hair loss due to a medication and liked it so much that I recently upgraded to the next-tier model (which is why I am selling this one). I am a haircare and skincare device junkie, and the science is there on this one! I recommend checking out Dr. Dray's YouTube videos (google "Dr. Dray + iRestore) for more information/a comprehensive overview of the tech (she also covers how it works for more standard forms of hair loss—androgenic alopecia, hormonal hair loss). I also think this device would be great for anyone generally committed to the health of their scalp/hair and/or looking to take preventative action against hair thinning (that is basically why I am using it at this point.) Device is used but has been well cared for and maintained. Device was purchased directly from the iRestore/Freedom Laser Therapy Amazon store. Please note that all of the photos and videos are of the exact device that you will receive (except for the last one, which is a screenshot of my receipt). The weird video is because the device (by design!) will not start a session until it is positioned on a head. (This is important to note if you buy it!)
