Dudes! Most of these (negative) comments are made by freaks! Don't listen to them. Here's my story using Kevis: The guy I spoke to was completely up front. He said I wouldn't see ANY results for about 6 months and then said I would get BACK to around 70-80% of where I was (at the time I had about 50-55% left). He explained the science and other products I asked about with an un-biased opinion. He also told me there was no money-back guarantee UP FRONT when I asked -so those of you whining about getting your money back... Doh! This product freakin' works!!!!!!! Just like the guy said-around month 6 or 7, I had about 10-15% added in thickness and I was actually strting to see new little baby hair on my crown. Yeah, baby! After 9 mos. they were getting longer and thicker. All the Rogaine in China hadn't done squat to my hair, up to when I started using Kevis. It's been almost two years since I started using Kevis. Now I only use it twice a week. I have about 75% of my hair-JUST LIKE THE GUY SAID!!!!!!!!! He emphasized using it correctly and long enoogh to get results. If you only use it 3 or 4 months, no duh, I wonder why it's not working? It's also pretty easy to use. Takes about 3 minutes after a shower. Also, every time I call Kevis, I speak to the same two people-there is no bankruptcy going on (which I asked about after reading this website) which they laughed about. I have a science background and everything these guys (and gals) are about-MAKES SENSE. If Kevis doesn't work for you-it probably means YOUR follicles are morte'- DEAD. Which they also tell you up front -by the way. Don't ruin the possibility for others. Geeeeezzzzzz!!!!!!!!!!!!
