Study: That blue hair likely signals her depression and volatility

Critics of woke western women have been thinking it for years, and a scientific study confirms it: blue-dyed hair shows a clear correlation with mental illness.
Okay, so we should know that in nature, if an animal is poisonous, it often wears a loud, bright outfit—think neon frog—that basically screams, “Eat me and regret your life choices.”
Exhibit B:
Here are four prominent news stories from the US and English-speaking world involving women with brightly colored blue, pink, or purple hair who were linked to publicized crimes, controversial acts, or protests. These examples span various contexts, from vandalism and environmental activism to civil unrest and historical riots.

- Victoria Jayne Bay (Blue Hair -photo above) – Anti-Trump Vandalism (US, 2016) A 37-year-old woman with blue hair was arrested in Los Angeles for scrawling anti-Donald Trump graffiti on multiple government buildings using blue spray paint. Surveillance footage captured her defacing walls with vulgarities about the president-elect, leading to charges of felony vandalism. She was held on $10,000 bail.
- Phoebe Plummer (Pink Hair) – Just Stop Oil Protests (UK, 2023-2024) The 22-year-old “poster girl” for the environmental group Just Stop Oil, known for her pink hair, has been arrested multiple times for disruptive protests. Notable incidents include throwing tomato soup on Vincent van Gogh’s “Sunflowers” painting at the National Gallery in London (a controversial act of vandalism) and breaching bail conditions while delivering a letter to a politician’s home. She vowed to be arrested “at least five” more times in a short period to draw attention to climate issues.
- Rebecca Ann Leathers (Purple Hair) – Anti-ICE Protest Assault (US, 2026) During a Memphis protest against a fatal ICE-involved shooting, a woman with purple hair was arrested for assaulting officers. She allegedly banged on a state trooper’s vehicle windshield and window while screaming and attempting to enter it, refusing to cooperate. She faced charges including disorderly conduct and resisting detention amid heightened tensions at the rally.
- Marsha P. Johnson (Brightly Colored Wigs, Including Vivid Hues) – Stonewall Riots (US, 1969) The iconic transgender activist and drag performer, often seen in bright wigs (frequently in bold colors like pink or purple shades as part of her flamboyant style), played a key role in the Stonewall Riots in New York City. She was involved in the violent protests against police raids on the Stonewall Inn, a pivotal event in LGBTQ+ history that involved clashes, arrests, and resistance to authority, sparking the modern gay rights movement.
The above are verified newsworthy events and controversies and there are many more out there if you look for them.

Results
- Main Findings: Unnatural hair color was associated with poorer mental health (β = -0.33 in simple model, reducing to -0.23 in full model with all controls). This indicates a moderate correlation, persisting after adjustments.
- Other Correlations: Vegetarianism (β = -0.19), bisexuality (especially in females, β = -0.23), polyamory (β = -0.14), and certain body types (e.g., overweight, β = -0.59) also linked to worse mental health. Conservatives reported better mental health (β = 0.54 vs. liberals). Tattoos showed weaker or non-significant effects.
And just for extra conspiracy-theory flavor, in the current world of mass political protests there’s been a noticeable boom in both rainbow hair and public discussions about mental health, particularly among left-leaning folks. Coincidence?

It appears we’re witnessing a slow-motion, follicle-based alarm system evolving in real time. So next time you see a magnificent lavender mohawk, maybe don’t just compliment it—consider it a public service announcement.
Discussion and Conclusion
The study confirms a correlation (not causation) between unnatural hair dye and poorer mental health, even after extensive controls. The authors suggest unnatural hair color may serve as a “behavioral marker” for underlying instability, similar to other non-conformist traits. Limitations include self-reported data (potential bias) and the dataset’s focus on daters (not general population). Future research could explore causality, e.g., via longitudinal studies.
