My wife comments on how much softer my hair is since I've been using the Lasercomb. However, we also put in one of those shower head filter units that BHD recommended (it is fantastic, BTW), and I'm sure that has helped too. Still, my hair is quite a bit softer than my wife's hair now, so that filter isn't the sole reason. I've also noticed that my hair looks much better and is more manageable since I've been using the Lasercomb. I've been using it a little less than two months. I also have significant regrowth and much better scalp coverage, but since I'm also using the big three and Folligen, I have no idea how much the Lasercomb has contributed to that.
