These days, Mandy Moore is best known as the matriarch, Rebecca Pearson, on This Is Us, sporting her classic brunette locks in an array of throwback styles. But the 33-year-old had a *very* different look when she burst onto the music scene as a sunny Cali blonde with her debut single 鈥淐andy鈥 back in 1999. Now, after 16 years of darker stands, it seems the 47 Meters Down actress is ready to return to the one hair hue that used to make her 鈥渟hudder.鈥

Immediately after wrapping filming on season two of the hit NBC show, Moore made a totally drastic change to her look, saying buh-bye to Rebecca鈥檚 signature strands.

The singer posed for a glam selfie with hairstylist, Ashley Streicher, which showed the ladies totally twinning with the prettiest beach blonde tresses for spring. Joking that she鈥檚 鈥渟lowly morphing into鈥 Streicher, she wrote, 鈥淣ow if I could only master those 鈥榗ool girl鈥 waves all on my own. And yes, I wasted no time changing up my hair as sooooon as wrapped up the season on #thisisus. As you do鈥 馃懐鈥嶁檧锔忊

The changeup was a seriously surprising one for the starlet, who told POPSUGAR as recently as October that her former blonde locks were not exactly her jam. 鈥淭here was definitely some dated hair that was not good. I look at anything from when I was a blonde, and I shudder a little bit to myself. I know it鈥檚 not terrible, and it was very of-the-moment, but it鈥檚 so not me. It seems so like a completely different person.鈥

Then again, this isn鈥檛 your typical bottle blonde, with celebrity colorist Tracey Cunningham opting for a soft, masterfully blended sunny do over the near-platinum tresses her client once rocked.

In fact, it just might be her best look yet!
