Olympic synchronized swimmers take J-E-L-L-O steps in perfecting their hair

Go for the gold with this gelatin trick.

Need to make a statement in the water? The U.S. Olympic synchronized swimmers revealed their best secret in maintaining their hair in the pool: Jell-O.

Synchronized swimmers, Anita Alvarez, 19, and Mariya Koroleva, 26, not only dished on their make-up tips in the water, they gave gelatin a shout out!

The duet swimming partners told Vogue that they use Knox gelatin ($6) in their wet hair, since they don’t wear swim caps. “You comb or brush that into your hair, put it up in a bun, and put a headpiece over that, so when it dries, it gets really hard and your hair doesn’t fall out when you swim,” the swimmers said. “We like to add glitter and other decorations to it—it’s easy.”

Another tip Alvarez and Koroleva divulged? To waterproof their eyeshadow, they use Aqua Seal ($21).

The women, who have been performing for two years together, are fans of MAC eye shadows in particular. “There’s a rule in synchro that your makeup has to be natural — not real-people natural, but synchro natural. We use neutral browns, and MAC’s Honesty ($16) is a nice one with some sparkle. Then we’ll put white or silver shadow ($16) under the brow to accentuate the eye a little more.”

As for a waterproof base? Team USA’s swim duo likes to use Make Up For Ever Ultra HD Invisible Cover Foundation ($43).

To maintain that bright red lip, the partners prefer matte over gloss, especially in the water.

Unlike other sports, the make-up is crucial for practical reasons and beauty reasons. “You’re swimming far from the judges and the audience, so you have to put on a lot to help your features show from far away,” Alvarez said.
