Gabrielle Union, Keke Palmer, Uzo Aduba and Marsai Martin are joining forces to end Black hair discrimination.

To help raise awareness about the harmful biases against Black women because of their hair, the ladies have teamed up with the Crown Coalition and Glamour to speak out against society's racist standards of beauty.

Earlier this week, Glamour officially released their hair issue, as well as a PSA that featured all four actresses sharing their experiences with hair discrimination. Union began, "I've been told it's too big. When I first started pageants, I was told by many to never let my hair be natural for competition. The first time I walked into the office with my natural hair, my supervisor asked if it was forever."

Palmer, 27, added that she had to deal with unsolicited advice. She explained, "I've been told it blocks people's view. HR told me my hair looked more professional pulled back and in a bun than it did out and curly. I am not my hair, but my hair is a part of who I am and it deserves the same respect as the person beneath it."

Meanwhile, Black-ish star Martin revealed that she has dealt with bullying. She said, "I've been mocked and ridiculed for the frizzy coils that escape my tightly-wound bun. I've seen children humiliated at school. Getting suspended. The baby girl whose teacher cut her hair because her beads were making too much noise? Those actions are bullying, discrimination, microaggressions and acts of racial injustice."

Aduba also mentioned that she's been on the receiving end of backhanded compliments because of her hair. She added, "I had someone tell me, 'Your dreadlocks are so nice and clean!'"

Towards the end of the PSA video, it's revealed that there is now state-level legislation that prohibits race-based hair discrimination at school and in the workplace, known as the CROWN (Creating a Respectful and Open World for Natural Hair) Act. Since research has shown that Black women are more likely to be judged harshly because of their appearance and sent home from work because of their hair, the campaign is now fighting for their right to wear certain hairstyles without facing consequences.

Palmer said, "My hair has a purpose greater than myself and I will not put it away to comply with white culture's standards of beauty."

Union also added, "This isn't just a hair issue. Hair discrimination is racial discrimination. Period. Together, we can make our schools and workplaces safer and equal for all."
