Barrymore shared a sweet snapshot to Instagram showing her getting her hair dyed alongside her little girl. Olive clearly didn't want to miss out on the fun, so her mom noted that stylist Tracey Cunningham "puts conditioner in foils on her for solidarity."
Barrymore isn't content with simply getting styled, however. The actress also shared a video of one aspect of her rigorous exercise regime, which includes yoga, stretching and lunges.
"Start training with @marniealton and lose 10 pounds by eating super clean with @_kimberlysnyder who helped me lose 20 pounds for season one," Barrymore captioned the sweat-drenched clip. "After all the #santaclaritadiet is pretty severe. Gotta get back on track."
"[Turning into a zombie] becomes an awakening for [Sheila's] life, and that gave me one too," Barrymore shared. "I lost like, 20 pounds playing her and had an attitudinal shift and plucked my eyebrows and, I don’t know, just started thinking like a woman again. And it was amazing."
"[Sheila] has got this great feminist empowerment thing going for her that I think was very positive for me," Barrymore added, joking, "in a very sick and wrong way." Check out the video below to hear more.
