Getting your eyebrows right
According to brow experts, creating the perfect eyebrows is perfectly simple.
Kurtis Dam-Mikkelsen, also known as Miss Fame , says there are five simple steps.
She told Elle.com : "The first thing you're going to do is comb your hairs up to see where they need to be filled in, starting from the front working towards the tail of the brow."
