General Trends (Globally):
* Brown hair is statistically more common globally. Since a larger percentage of the world's population has dark hair naturally, even without considering dye, brown would be considered more popular in a statistical sense.
Trends (Specifically in Western Culture/Media):
* Blonde/Light Brown & Brownish-Blonde: Often considered more glamorous and desirable, especially in the media. This is often seen in Western cultures that strive for a "sun-kissed" look. Brownish-blonde tones have been very popular with salon requests.
Things to Consider:
* Region: Hair color preferences can vary widely between regions. For example, blonde is more common in Northern Europe than in East Asia.
* Current Fashion Trends: Trends fluctuate. What's popular one year might not be the next.
* Age Groups: Different age groups may have different preferences.
* "Popularity" can mean different things:
* Most common: Brown would win out.
* Most requested at salons (in some regions): The blonde/brownish blonde tones or highlights might be more requested in certain regions.
Conclusion:
While brown hair is statistically the most common, in many Western cultures, blonde or brown-blonde, and carefully styled and colored brown shades are often perceived as more popular or desirable, especially in fashion and media. Brownish-blonde has been trending for its blend of warmth and brightness.
