Famous as one of the twin daughters of hairstylist and Instagram sensation Jill Ehat, she frequently models elaborate hairstyles -- mostly braids -- on her mother's social media accounts.
She appeared in her first Instagram post -- captioned "Twin Double Dutch Braids!" -- on April 27, 2014.
Her mother's popular Instagram account has earned over 70,000 followers.
She and her twin sister, Brighton, grew up in Utah. They have an older brother named Cole.
Like YouTuber Mimi Ikonn, Hallie's mother rose to online fame for posting images and tutorials of hair braiding.
