Nanogen Hair Thickening Keratin Fibres Black

Work pretty well. Water resistant As long as the fibers can grab on the thinning hair. Looks natural as long as you spray sprites then apply the hair fiber and then blow dry the rest away!The black well look grey at first but then becomes black so don't worry! I high recommend this for men that's fight hair loss!

Did not cover up well and would come off on to your clothes

it is kind of powder instead of being hair thickner!

Actually i'm disappointed that this Hair fibers did not work for me. I was having high expecations after i saw the reviews and ordered it. But when i applied it, it did not stand even for a day on my head. Forget about the bald area, even where i have thin hair, it was not sticking beyond a few minutes. I comb my hair after 30 minutes of applying the fibers, all those fibers were in my comb!!Product packing had a catalog which says i need to buy some hair spray for these fibers to stay longer......but no videos had that as a first step before pouring the hair fibers on our head.It will stay even when we go in the rain, take a shower, sweat out etc are all false statements!!I thought i had a solution for my thining hair...but looks like hair transplantation is the only permanament solution for thining hair and baldness.

Not worth money, difficult to use

I have been using it now for over a year and would recommend it.

nice product i would buy again!

This is the worst thing you can put on your hair, this product is supposed to help hair loss, yet you put this product on your scalp and it, irritates, causes itchy and redness. A lot of people don't realise that the very product they are putting on their scalp is causing them problems. This is not a natural product, next time you put this on your scalp see if your scalp is itchy or irritated, stop the product get a natural one and see the difference
