The "Younger" star took to Instagram on Friday, where she showed off her flawless face with a makeup-free selfie.
In the candid snap, Duff poses for the camera without a stitch of makeup on as her new long locks are styled in loose waves.
"My hair my hair... Magically grew over night #nomakeupalldayfeltsoright #thankgodforfilters," she captioned the pretty pic.
While Hilary clearly added some extensions, she showed off her cute shoulder-length 'do earlier this week when she attended the Justin Bieber's Los Angeles concert with her sister Haylie Duff and some friends.

The mother-of-one can pretty much pull off any look she wants, though!
