I have used this product for a short period and I think it is just as good as the more expensive products (many of which I have tried). I have noticed some growth but think I need to keep using this for longer to provide a more accurate assessment of the product. I would buy it again.
I have a small 'gap' (bald patch) in my brows (from over plucking in the 80s) and have used this product for the past 5 months, while I can't say I can see any significant re-growth - the gap in my brow is certainly much easier to 'fill-in' and disguise.
I will be purchasing this product again.
Saw results even after two weeks of use. Price really good given that you need to order again soon as opposed to other beauty products that last longer. See-through applicator also very convenient because you can see how much you have left.
