The movie, which is based on the best-selling book by Trisha R. Thomas, follows a successful woman anticipating a wedding proposal from her longtime boyfriend. When he refuses to drop down on one knee, she cuts him off and her hair. The big chop leads her down a road of self-discovery.

When Lathan shaved off her own hair for the role last year, she revealed her new look on Instagram. "I feel so light, I could fly away," she said in the video.

"Nappily Ever After" will be available starting Sept. 21 on Netflix. Watch the trailer below.
