【Caught in the Act: Promiscuous Sex Life of My D-Cup Mother in law】

Lupita Nyong'o has called out Grazia UK for photoshopping her hair on Caught in the Act: Promiscuous Sex Life of My D-Cup Mother in lawthe cover of its latest issue.

The 34-year-old Oscar winner expressed disappointment that the publication "edited out and smoothed my hair to fit a more Eurocentric notion of what beautiful hair looks like."

Nyong'o also shared a lengthier statement on Instagram, saying that there was still a "very long way to go to combat the unconscious prejudice against black women's complexion, hair style and texture."

She ended both her posts with the hashtag #dtmh (don't touch my hair), which was quickly picked up on Twitter.
