"I’ve always had very sparse and thin eyebrows, and no matter how many products I tried, nothing worked. But after using this serum for 3 weeks, I started noticing tiny hairs popping up where there used to be almost nothing! It was such a small change, but by the 3-month mark, my eyebrows were completely transformed. They're so much thicker now, and I don't even need to fill them in with makeup anymore. This serum has completely changed the way I feel about my eyebrows!"
