For some background, I am a 23-year-old male. Sadly, I was hit with severe and rapid hair loss in the front and back, initially noticeable when I was turning 21. I've been on Rogaine for about two years, and can't say that it has made any difference, so I figured I'd try something new.
I purchased the iGrow in June of 2017, have used it 2-3 times a week as directed, every single week since June 2017. It is now March of 2018, and I can't say there is even the slightest of difference in my hair density. If anything, I might have lost more since I purchased the device, but I think it's due to the progression of hair loss and nothing to do with the device, although I still believe the iGrow helmet hasn't made any difference.
I am unsure if it's a scam or if my hair loss is just severe enough that the ever so hyped lasers have no effect, but from my perspective, I would not recommend.
Bottom Line: No, I would not recommend this to a friend
