Review (4/5): Know how to use it.
I have been using this for about 3 years now. I have lighter blond hair when it comes to my eyebrows so it looks like I only have half an eyebrow. Let me tell you chicks don't like that. I tried this product and to me nothing beats it so far. You can go as dark as you would like because it depends on how long you leave it on. For me the best method is to cover the very light part of my eyebrows and Link that on for about 30 seconds then apply to the rest of the eyebrow and leave that on for about another 30 seconds. Mine come out perfect each time. Do not full bleed wash your face right afterwards and I would not take a shower for at least 2 or 3 hours afterwards to let the colorful fully set. If you do one minute intervals you will not die the skin and you will keep yourself from going to dark and working absolutely weird. I use the extra on my beard just to give it a little more Darkness around the mustache. To me it varies on how long it lasts. I have gotten about a month out of it off one application and then I have had to reapply after two weeks. The more of the cream you put in the longer you will need to let it set otherwise to me it fades a lot faster.
