Millie Bobby Brown shared an Instagram video on March 25 showing herself with a new, bleached blonde bob. Then on March 29, she shared a series of photos on Instagram of herself wearing a bikini and sporting longer brown hair on a beach.

“Stranger Things” actress Millie Bobby Brown, 21, made a dramatic hair change, swapping her platinum locks for her original deep brunette shade. Quite the beauty risk-taker, the starlet debuted her fresh new tresses on Thursday at the semi-final of the Miami Open, which was held at Hard Rock Stadium.

The 21-year-old "grew up with no money" before receiving the life-changing call that she had been cast on Netflix's "Stranger Things." In an appearance on the " Call Her Daddy " podcast, Brown said that her upbringing has had a profound effect on how she thinks about her finances.
