Alexandra Grant has called out dangerous beauty standards while explaining why she does not dye her grey hair.

The artist, who is dating Keanu Reeves, discussed the subject on Instagram, where she posted a screenshot of a new study that found using permanent hair dyes and chemical straighteners is linked to an increased risk of breast cancer in women.

“Wow. Today’s news…” Grant wrote. “The numbers are staggering, especially for womxn of colour.” Womxn is an alternative spelling of women used to explicitly include transgender women and women of colour.

“I went grey prematurely in my early 20s… and dyed my hair every colour along the way until I couldn’t tolerate the toxicity of the dyes anymore,” she continued. “In my 30s I let my hair turn ‘blonde’... I love and support that every womxn can choose how she wants to look at every age. But/and, if womxn are perishing from beauty standards… then let’s talk about those beauty standards!”

The 46-year-old concluded the caption: “Love to all womxn!”

According to the study, published in the International Journal of Cancer, women who use permanent hair dye are nine per cent more likely to develop breast cancer than women who don’t use the products.

The risk is greater for black women, with the use of permanent hair dye associated with a 45 per cent higher risk of developing the disease.

In response to the post, Grant, who went public with her relationship with Reeves last month on the red carpet at the LACMA Art + Film Gala, has been praised for using her platform to advocate against harmful beauty standards.

“Thank you for sharing this insight and something so personal,” one person wrote.

Another said: “Thank you so much for sharing this important message.”

Grant and Reeves have been friends for years and previously worked together on the actor’s books Ode to Happiness and Shadows.

The couple also co-founded the publishing house X Artists’ Books, which publishes “thoughtful, high-quality, artist-centred books that fit within and between genres,” according to the website.
