Remember in the '90s when everyone had uber-skinny, highly-arched brows?

Those days are over, as women are 86-ing their tweezers in favor of a no-arch look, according to a new study in the Clinical Plastic Surgery journal that predicts an arched brow will soon be obsolete.

The ideal eyebrow has been moving lower to the eye for a whopping 60 years now, the Independent notes. The result? Our brows are making us look more masculine.

For a recent study, analyzers at the University of Southern California examined the brows of models and women in fashion magazines from 1946 onward and found an interesting trend: not only have eyebrows gotten progressively fuller, but the peak of them has moved further from the nose; in other words, brows are getting flatter. Bye bye, sperm brows!

The secret reason for this? Fluid gender dynamics, according to Mark Soldin, a spokesman for the British Association of Plastic, Reconstructive and Aesthetic Surgeons, who told the Independent:

"Upward curvature of the eyebrows was considered to be an attractive feminine feature in the past. We are finding that more and more women are looking for a flatter, straighter, more masculine look. I think it has to do with the increasing equality of the sexes. Women are subconsciously favouring a masculine brow."

Subconscious gender flux or not, the fuller brow has been in for some time, modeled by young Hollywood royalty like Emma Watson and Camilla Belle. Some women are even turning to hair transplant surgery to fill in their overplucked brows.
