The Honest Company founder is no stranger to changing up her look — especially when it comes to her color.

In June last year, celebrity hairstylist Brittney Ryan opened up to PEOPLE about Alba dying her hair for a project at the time, saying "Jessica is always up for a change, and we decided to go dark brunette for an upcoming movie role that she will be filming soon."

While she loves to shake up her hair color, the mom of three typically sticks with an easy style that makes her look effortlessly put together — something that's important for someone who runs a billion-dollar empire.

"Jessica is constantly juggling between business woman, mom, content creator, and actress, so beachy textured waves with a middle part always works for her," Ryan explained. "It's been her go-to look for years because it can easily transition from being messy and textured to brushed out and smooth."

In September, Alba spoke to PEOPLE about how she built the Honest Company from the ground up, revealing that she worked tirelessly to get the ball rolling on her dream company.

"I actually had the biggest vision right away, and then I had to bring it down to earth," she said. "I just knew in my heart that this company should exist. If people knew that they could take their health and wellness into their own hands and make better choices, why wouldn't you? The hardest part was probably getting it off the ground."

Added Alba: "Every detail mattered. So I didn't sleep very much, and worked weekends and obsessed."
