    Most effective!!

    I didn't think I'd ever find a product that works like this serum. My eyebrows were almost gone. I thought I'd be using a fake looking pencil forever, but I honestly watched my brows begin to fill in within a couple weeks!!

    Yes and then some

    I read some 1 star reviews just for FYI. I can definitely relate with products that work well for others and not for me. This product is all it reports to be and then some for me. In fact, to be honest, my brows have gotten too dark and I resemble Maleficent (have to do something about that). I think the product darkens my brows more than assists the growth of the hair to make them fuller but I will take it. As for the amount of the product, I have to delay my auto-shipping all the time because there is plenty of product in the tube although I have never had the problem of a dry tube. Unfortunately, most products do not produce a permanent fix and you must use it all the time to get the results you want and it does cost A LOT (Example - Latisse)

    New Brows

    I’m in my late 50s and my eyebrows were basically disappearing over the years, and this has done wonders after just 3 weeks. Ive tried other eyebrow serums in the past but this has worked the best of any. New hairs are sprouting and it’s darkened them, which I love. There’s still a small area that was over plucked many years ago that I’m hoping will fill in over the weeks…. We shall see!

    This really does thicken eyebrows as well as darkens them. I noticed a big difference after about 6 weeks.

    Amazing

    I am 68 years and had lost most all of my eyebrows and after using I no longer need to use eyebrow pencil. So happy with this product!
