My previously sparse eyelashes look amazing these days - because I have extensions! I opted for mink extensions, because mink lash extensions look very real. However, they are not for everyone, partly due to the cost, so if you cannot afford them, I would suggest you opt for an enhancer for lashes instead. Lash enhancing products like make eyelashes longer and thicker; but the effect is temporary.
Theres a spate of products on the market that make eyelashes thicker and longer, at least temporarily. DivaDerme, Dream Lash, and Talika all lengthen and thicken eyelashes considerably; application can be tricky, but once the technique is mastered, your eyelashes will definitely take on that fairytale princess look.
