Milani also makes a good brow kit (I looked, and discovered Milani began selling in Romania in 2012).
Here's a link to the Milani brow kit from the Milani website:

If your brows are both sparse
and light, for the most natural look I'd recommend you use a powder or pencil to fill in your brows
and something to tint your brow hairs as well. I make my own brow tint using e.l.f. Essential Wet Gloss Lash & Brow Clear Mascara (
http://www.eyeslipsface.com/elf/eyes/mascara/wet_gloss_lash_and_brow_clear_mascara). I take the tip of the brush from the Lash & Brow Clear Mascara (either end will do), and touch it to the tip of the brush from a regular colored mascara (
not waterproof - either brown, dark brown, or black). When I've picked up a bit of the colored mascara on the brush, I insert the brush from the clear mascara back into the tube, and swirl it around a bit. This tints the clear product and when you apply it to your brows, it will tint the hairs as well. If the results aren't dark enough, just repeat the process until the clear is tinted according to your liking.
Because this tints the brow hairs with a translucent color (as opposed to opaque), the result is quite natural in appearance (with the added benefit of keeping your brow hairs in place).
