Mandy Moore is more than willing to change up her look 鈥 we see proof every week on This Is Us, when the 33-year-old is transformed into a 66-year-old woman for her role as Rebecca Pearson . Yet there鈥檚 one hairstyle in particular the singer says she鈥檚 definitely not in a hurry to revisit anytime soon: her former blonde hue.

In an interview with POPSUGAR , Moore opened up about her symbolically darkest hair days of yore, saying, 鈥淭here was definitely some dated hair that was no good. I look at anything from when I was a blonde, and I shudder a little bit to myself.鈥

As we previously reported , the newly engaged star鈥檚 big tress transformation came after taking on the role of Jamie Sullivan in A Walk to Remember at just 16 years old. 鈥淚t was transformative because it came at a time in my life when I was only seen in the pop music landscape and through that lens. There was real significance to coloring my hair,鈥 she explained.

Needless to say, the natural brunette (yep, it鈥檚 true 鈥 Moore ISN鈥橳 a natural blonde. Who knew?) never looked back 鈥 and for good reason. 鈥淚 know it鈥檚 not terrible, and it was very of-the-moment, but it鈥檚 so not me,鈥 she relays to POPSUGAR now. 鈥淚t seems like a completely different person.鈥

She also wasn鈥檛 here for her former character鈥檚 wispy fringe. 鈥淚 have told my close friend and boyfriend (now fianc茅!) if I ever talk about cutting my bangs again to pull me aside and remind me not to. Because, anytime I cut my bangs, it鈥檚 that immediate sense of, 鈥楥ool! I鈥檓 already growing out my bangs again鈥︹ They鈥檙e pretty unfortunate, and they were really hard to grow out,鈥 she says.

Nowadays, she鈥檚 found her perfect happy medium. 鈥淚 definitely feel like where I am right now feels like the most me. It鈥檚 a little darker than I think my natural color is. It鈥檚 a bit warmer. I tend to be a bit ashier. [This is] the one that requires the least maintenance. And at this point in my life, that鈥檚 what I鈥檓 grateful for.鈥

Fair enough!
