After I had my baby, I lost a lot of hair (thanks, hormones) and had a few sparse spots that made me feel very self conscious. My hair dresser recommended this and I love it. It's slightly darker than my natural hair color, but it really doesn't seem to make a difference. A little goes a long way and makes the spartan parts of my hair look fuller and thicker. My hair has since grown back, but I have fine hair so I still use it in places. Love it!
