The $17 Hair Color Tate McRae Used For the 2026 Grammys

When it comes to sourcing new beauty inspiration, we can always count on celebrities on the red carpet to introduce us to a new product or show-stopping trend. Last year, we saw the return of some old favorites — like Taylor Swift's trusted red lip and the controversial jellyfish haircut — and this year, we're already seeing some affordable beauty surprises (we're talking under $20!).

While celebrity glam is more typically associated with high-end, luxury beauty products, many celebrities use more budget-friendly products for their red carpet looks. Tate McRae used a $17 hair gloss; "Love Island" star Olandria Carthen used $10 body oil for her red carpet glow; Keke Palmer grabbed $9 mousse to keep her hair frizz-free; Selena Gomez opted for a $16 cleanser to prep her skin; and Kendall Jenner kept her rainy Met Gala look in tact with a $14 setting spray.

Ahead, we rounded up the best affordable beauty products under $40 that today's biggest stars relied on for their red carpet appearances this year. From drugstore favorites to hair-care staples to plenty of editor-approved skin-care products, these beauty must haves will make it easy to achieve A-list glam — even if you're on a budget.
