When it comes to reinvention,nothing changes a look like new hair--and these celebrities prove it. Here, an ongoing look at the biggest length, bangs and color changes in Hollywood.

 


Emily Ratajkowski

While prepping for the 2018 Met Gala, EmRata debuted a shocking pixie cut on Instagram. Her hairstylist Jennifer Yepez hinted that it was a crazy-convincing wig, writing, "Saving this one so stay tuned." Ratajkowski said the same: "Didn’t work out for tonight butttt...stay tuned!"

 

 

Demi Lovato

The singer, whose super long hair has been a signature look, debuted a new chin-length bob cut by César Ramirez on March 31.

 

 

Chrissy Teigen

On the 2018 Grammys red carpet, the model debuted a brand new look. Her usually long, caramel strands were updated with a short, shaggy bob cut.

 

 
Blake Lively

The actress shared a short clip on Instagram in January 2018, revealing a dramatically different hairstyle. Even though this might be a wig, as Lively is currently filming a movie called The Rhythm Section, the short brown style totally suits the usually blonde actress.
