Kelis turns a young 38 today and though we’ll forever appreciate the singer for the girl power anthems she’s given us over the years — hello “Milkshake” and “Caught Out There” — it’s her mane that keeps Kelis forever in our minds.

Kelis was natural before natural was a thing, and throughout her career she’s showed us what hair is really all about — expression and having fun! Truthfully, Kelis has rocked more looks in more colors than we can recount but we’re shouting out some of our faves today in honor of the birthday girl. Tell us which looks you love the most.
