Have you ever wondered how Oscar winner Jared Leto, acclaimed star of Dallas Buyers Club and the lead singer of 30 Seconds To Mars, maintains his long, radiant hair and gets that old-school rock star look?
As it turns out, it's the work of celebrity hair stylist Chase Kusero, who sat down with ET's Rocsi Diaz to reveal the secrets of the 42-year-old actor's long locks.
"He has a great eye, and he knows what he likes. He definitely has input," said Kusero, who has been styling Leto since 2009. "I think that, because I've been working with him for so long, he does have a lot of trust in me.
"He likes it to be a certain way, and I think that’s where I come in," Kusero added. "It's more of just controlling a natural look. Because he is very natural."
Another style secret? Kusero revealed that he used Vidal Sassoon Pro Series products on Jared for the Oscars.
