I think the only person these would work for (possibly) would be someone who shaved their brows completely and then used a concealer to cover any previous tattoo markings or someone without ANY hair. I have sparse brows with previous microblading. They don't work at all for me and I've tried on MULTIPLE occasions to make it work (cutting in half, whole, etc). And, the brown is red. You can ONLY get a refund if you send back any UPOPENED or UNUSED sheets. So, if you try each sheet you are SOL. :-(
They continued to shine and show the glue EVERY time and no amount of powder works.
