So you want to know how to achieve long, thick lashes without having to put falsies on? I have THEE perfect mascara combo and it won't cost you a fortune either!
FIRST! Start by combing your lashes, honestly any one will do. I use this retractable Sonia Kashuk Lash Comb. Combing them out beforehand will separate the lashes so that they can grab the mascara and take better shape.
Then I go right into applying 2 coats of L'Oreal Voluminous False Fiber Lashes Mascara. After each coat, let it dry and then comb it out.
Finally, apply 2 more coats of the L'Oreal False Fiber Lashes Mascara, making sure to dry and comb through between coats. And that's it! Sounds like a lot more work than it really is. =]
