I would first like to say that Hairguard's been a great company!! There customer service & support is absolutely GREAT and FIRST RATE!! They've always responded to all my questions and have always been super easy to work with - even with my returns. As far as product(s) go - I purchased their GrowComb several months ago and can say WITHOUT A DOUBT that it has been a life saver & HAIR SAVER. I started noticing a decrease in my hair fallout after about the first couple of weeks of using GrowComb (will refer to as GC). Today I notice just a few hairs that fallout, both in the shower & during styling. Before using GC I would always be stressed as to how much my hair would fallout while showering (as I could feel my hairs falling down my face when rinsing out the shampoo) and also see additional hairs in my sink when styling. Today, I am definitely much happier & less stressed because of the GC. On top of that I am saving much more money because for the last ten years I've been purchasing every kind of device & supplement to stop my hair fallout - yes, even purchased other light emitting devices/helmet. If you're still searching you MUST GIVE THE GROWCOMB a try. I have not regretted it at all.
