The ’90s are back this fall.

Yes, again. Whether you call it ombre, “unicorn hair” or simply wacky colored highlights, it’s evident that the rainbow-inspired manes of decades past are back, enthusiastically revived by celebrities like Lena Dunham, Cara Delevingne and Kylie Jenner.

Colored hair has also been spotted everywhere on the fall runways, from Ashish to Jeremy Scott. Perhaps most notably, the rising swath of pastel looks can be traced to the fall Gucci show, where stylist Paul Hanlon added pops of pink to models’ tresses.
