Cara Delevigne. Rihanna. Rachel Weisz. Julianne Hough. What do these women have in common? Magnetic personalities, yes. Top-of-the-line talent. Uh-huh. Drop-dead good looks. Yup. Amazing hair. True.

But what do you notice first in these four pictures?

Ladies, it’s their eyebrows.

Women tend to underestimate the power of a perfectly shaped brow. If your blowout and makeup are perfect, but your brows are unkempt, overplucked, meet in the middle…well, that’s just not going to work. Not only do these women have great brows, but they’re power brows. No fine lines here. Properly shaped brows should frame the face, lift the eye, draw attention, and two skinny anemic lines are not going to do that. These celebrity brows kick everything up a notch. They say, I deserve to be noticed. Now, don’t you want the same?

And another thing: don’t try this at home. Here at BLOWTOX we feel so strongly about good brows that we offer brow shaping seven days a week. Add it to your blowout and the service is only $20 in March (a $5 savings)! That’s $10 a brow! Not only that, a little brow pencil is a recovering pluck-aholic’s best friend. We’ve got that too, and we can show you how to use it.

So extend that spring cleaning thing to your brows this March—and unleash your brow power!
