Sexy Stars Turnin' Up the Heat With Spicy Red Hair

It's National Red Hair Day ... and, we've put together a gallery of stars with bright red locks lookin' spicier than a big bag of Flamin' Hot Cheetos.

While only about 4% of Americans are natural redheads, anyone can add a little rosy coloring to their hair ... just look at Megan Fox, who matched her glowing mane to her fierce nails!

Karol G put in similar coloring to her own long locks ... while Megan Thee Stallion decided to go with maroon instead of the more vibrant blazing red of these other stars.

Katseye's own Lara Raj also got adventurous with her hair choices ... throwing a little bit o' magenta in her hair and a sultry look on her face. Dua Lipa, Brittany Mahomes, Bella Thorne and more stars have hit their local salons to dye their locks, too!
