If not what is a natural effective alternative? I don't want to use Lastisse
Castor oil has absolutely no scientific proof behind it that it will work. It will definitely keep your lashes moist. But that's about it. Latisse is the only FDA approved treatment to grow your lashes longer, thicker, and darker. There isn't a natural alternative or anything that has any scientific or medical backing behind it.
