(CNN) —  

The California state assembly has passed a bill banning employers from discriminating against people with natural hair. It now heads to Gov. Gavin Newsom’s desk to be signed into law, making it the first statewide ban on natural hair discrimination.

SB 188 updates the state’s anti-discrimination laws so the definition of race includes “traits historically associated with race, including, but not limited to, hair texture and protective hairstyles.”

It passed the State Assembly on Thursday with a unanimous 69-0 vote.

The bill, which is also known as the C.R.O.W.N. Act (Create a Respectful and Open Workplace for Natural Hair), states that the standards of professional dress and grooming in workplaces and schools are often based on Eurocentric standards.

“Workplace dress code and grooming policies that prohibit natural hair, including afros, braids, twists, and locks, have a disparate impact on black individuals as these policies are more likely to deter black applicants and burden or punish black employees than any other group,” the bill says.

The bill will encourage schools and businesses to create grooming policies that foster inclusion and diversity, Mitchell said. African-American men and women have often had to endure expensive, painful and even dangerous chemical treatments to change their hair to conform to these beauty standards, she added.

In a speech before Monday’s vote, Mitchell said that African-American men and women have often had to endure expensive, painful and even dangerous chemical treatments to change their hair to conform to these beauty standards.

She said that until recently, an image search for “unprofessional hairstyles” only showed black women with natural hair, braids or twists.

“I believe that any law, policy or practice that sanctions a job description that immediately excludes me from a profession – not because of my capacity or my capabilities or my experience but because of my hairstyle choice – is long overdue for reform,” said Mitchell, who observed that she wears her hair in a natural style.

Mitchell said that similar state and federal laws protect against discrimination due to religious hairstyles and head coverings.

“However, there are still far too many cases of black employees and applicants denied employment or promotion – even terminated – because of the way they choose to wear their hair,” she said. “I have heard far too many reports of black children humiliated and sent home from school because their natural hair was deemed unruly or a distraction to others.”

Last year, a referee at a wrestling tournament in New Jersey drew widespread condemnation when he ordered a black high school wrestler to cut off his dreadlocks or forfeit his match. This month, a bill introduced in the New Jersey Legislature aims to ban discrimination based on hair.

In February, New York City passed similar protections on the right to maintain natural hairstyles that are closely associated with racial, ethnic or cultural identities.
