I never thought of myself as having SHORT lashes, I thought they were long but straight and light. I started using this in hopes they'd be darker or curlier (even though the product doesn't claim to do that), and worse case maybe a little bit longer wouldn't hurt either. started using 2/1 of this year. By 3/27 I thought maybe I was seeing results but wasn't sure. By 4/2, brow results were unmistakable, and by 4/15 it was the same with lashes. Lashes continued to improve until around 4/24 when I think results maxed out, but they were major. I don't think they got any darker or curlier, but they were much longer! I hadn't realized my lashes weren't quite as long as I thought they were. I had 3 people (family members that see me often) on separate occasions assume that I had fake lashes on! Including my BIL. I slacked off for a while and results faded to nothing, but now I've been back doing it twice a day for a few weeks and I'm noticing them coming back! So took a little while to see results but they were exactly what I hoped. Excellent product.
