UPDATE: Product arrived late and I had to call to have it replaced. I’m using as directed. You need to go online to find directions. Also, maRK the outside of the jar with a pen and watch the product diminish with every use! There’s almost an immeasurable amount of product in the vial. Every drop you use (every drop) you’ll see the amount of product diminish. So for $100 you get very little product and I haven’t seen a result at all yet. And as fast as this product goes, I doubt I’ll have time to see any results so I can’t give a fair review. The lash stuff I get from my Dr works in there weeks and produces long and thick lashes. Almost too long. I’m going to see Kerafactor through to the end, but I’m almost sure I’ll end up giving it 1 star. Too expensive for what you get and no results in the short time frame you have to see results with so little product. Sorry guys, I went in with an open and hopeful mind. Also, I’ve had clients research this brand on Tiktoc to no avail.
