Then vertical haircuts came along.
M&M Friseure Salon in Germany is challenging the whole notion of a good old-fashion trim with a recent Instagram post that's making its way around the world.
The video, which has nearly 100,000 views at publish time, features a stylist sectioning wet hair into four different ponytails and pulling each straight up into the air like a Troll doll. (There's likely some pomade or wax to help with the whole defying-gravity issue.)
The stylist then lobs off about an inch on each section before turning her scissors downward to cut vertically into each ponytail, a technique that's often used to create layers. A snip here, a snip there and she's done. Yes, that's really it!

She pulls out the ties, blow-dries the hair and voila! For all of you skeptics out there, the haircut is actually gorgeous. That same stylist even took on another client.
Now the question is: Will this crazy technique actually catch on stateside? Love them or hate them, the Kardashians are often at the forefront of trends and none other than Kendall Jenner seemingly underwent a major chop in a similar fashion before posing for Vogue's September issue cover.
According to her hairstylist, Garren of R+CO haircare, looks can be a bit deceiving.
"I was just chopping off a chunk of hair," Garren said, explaining that the "vertical haircutting" technique refers specifically to cutting down into the ponytail to create layers. "Kendall wanted a picture like Karlie Kloss had from when I chopped her hair off. She thought it would be fun to recreate it."
As for vertical cutting itself, Garren explained that the technique is not exactly new. Dating back to the 1970s, celebrity hairstylist John Sahag was known for creating shag haircutsby pulling hair forward before cutting layers. It's now used as a way to create piece-y styles — like the beloved "Rachel" from Jennifer Aniston's "Friends" days.
"It's not so happening now," Garren said of the layered look. "Hair is not as shattered looking and has more blunt (ends) these days."
But in case layers make a comeback — as trends often do — Garren cautioned that it's not the best look for everyone.
"It's important to consider the texture of the hair. It works well for medium-to-thick straight or wavy hair, but never do it on curly, frizzy or fine hair," he said.
And always go to a professional, he added. "It's a progression to learn the technique," Garren said. "It's not something that is taught right at the beginning. You have to be trained to slice into the hair."
With all of that in mind, would you be brave enough to ask for this technique?
