Sadie Sink's Stunning Hair Transformation

While some celebs are nearly unrecognizable with their natural hair color, others are known for their God-given, signature shades. Sadie Sink lands among Hollywood's most iconic redheads, and the "Stranger Things" star has remained committed to the bold color throughout her career. "I've thought about it, but I've never dyed my hair," she told Glamour in 2025. "No matter where you stand, what you hear your entire life as a redhead is to never dye your hair. 'People pay so much money for that hair.' So I never have, and I don't think I will."

Though the Texas-born actress has maintained her redhead status, she's still experimented with different cuts and styles for red carpet appearances and magazine spreads. In this way, just as Sink has undergone a stunning style evolution, she's also experienced a major hair transformation since entering the industry as a child star. Trying out everything from straightened strands to edgy chops, she's consistently wowed us along the way.

Sadie Sink took on the role of an iconic redhead when she was only 11 years old, debuting as the titular "Annie" in a 2013 Broadway production. While the scream queen sported a familiar mop of curls onstage, she showed off her natural texture when performing at 106.7 LITE FM's Broadway in Bryant Park event. Her red tresses were pulled back from her face with a simple, bow-adorned headband while slight waves fell down her back. "My hair is very full," Sink told Refinery29 in 2023. "The waves that I've worn in the past, that's just how my hair is naturally."

Regardless of her natural texture, Sadie Sink has fully proven that she can turn heads with a straightened hairstyle. Back in 2017, the budding actress visited "Extra" to discuss her role in Season 2 of "Stranger Things," contrasting her character's tomboyish styling with an edgy menswear look that she rounded out with sleek lengths. Not only did the middle-parted styling contribute to the modern aesthetic of the chic ensemble, the moment showed off some major hair length. With such head-turning looks, we're not surprised that Sink quickly became known for her long, redheaded hairstyles.

Next, Sadie Sink added to the list of simple ways to style your hair that still look chic, attending the 75th Annual Golden Globe Awards with an elegant ponytail. The star's tresses were pulled together at the crown of her head and fell into gentle waves down her back while a velvet bow brought a sense of playful elegance to the look. Celebrity hairstylist Ryan Richman showed off a snapshot of the red carpet look on Instagram, shouting out Paul Mitchell products for helping craft the standout look.

Sadie Sink infused her signature red locks with Hollywood glamour at the 2020 SAG Awards, wearing her hair in a side-part with loose curls at the ends. She paired the elegant style with a polka-dotted Gucci gown, embellished with jewels, and a monochromatic makeup look, accentuating her blue eyes with a soft shade of pink. Not only does the entire ensemble balance a dreamy feel with red-carpet glam, but the shiny, healthy look of Sink's hair has us wishing she'd drop the haircare routine.

Sadie Sink proved that she has perfected the glamorous, lazy-girl mermaid waves when attending the Venice International Film Festival in 2022. For the "The Whale" red carpet, the Hollywood figure wore a floor-length Alexander McQueen gown featuring a lavender skirt and revealing bodice cutouts. She paired the high-fashion ensemble with uniform waves that felt fit for a magical sea maiden, with the middle-parted style falling well-past her shoulders. If you want to recreate a similar look, then it's time to invest in a hair tool like Revlon's 3 Barrel Jumbo Hair Waver.

Sadie Sink joined the list of celebs who made the leap from long to short hair in 2023, blowing fans away when she went the extra step and opted for a retro mullet. Celebrity hairstylist Tommy Buckett shared a snapshot of the voluminous look to Instagram, telling Vogue, "When I was doing it, I was thinking that people are either gonna love me or absolutely hate me." The remnants of the rockstar look were still present when Sink attended a Miu Miu event during The 80th Venice International Film Festival in September. While the cut is majorly different from the celeb's long lengths, it's undeniable that she wears a mullet with confidence and edge.

Sadie Sink put a modern spin on her shortened red hair during Paris Fashion Week in June 2024, sporting a slicked-back look to the high-profile event. The style definitely felt reminiscent of her '80s-channeling mullet, but brought a trendy edge with the faux-wet appearance. When speaking to Refinery29 in July 2023, the "Stranger Things" actress admitted that she initially cut her hair for a role. "I never really thought about cutting my hair in my own life. It never crossed my mind to do something like that," Sink said. "But once it happened, I felt very empowered by it."

Sadie Sink continued to sport shortened hairstyles in 2025, appearing at the opening night of "John Proctor is the Villain" with a collarbone-length cut. The Texas native wore her red tresses in a middle-part with casual, small curls around the chin and shoulders, pairing the 'do with a red lip, pendant necklace, and velvet gown. The overall ensemble definitely cultivated a "whimsigoth" aesthetic, channeling the '90s via the textiles and accessories and enhancing the witchy vibes with Sink's voluminous curls. For those ready to steal the witchy '90s aesthetic of "Practical Magic," this is definitely a look to add to the mood board.

Rounding out the actress's hair journey, Sadie Sink appeared at the premiere of "Stranger Things" Season 5 with her red locks styled into a majorly chic look. The middle-parted hairstyle featured distinct layers cut below the chin that were rounded inward for a face-framing effect. A behind-the-scenes TikTok shows that stylist Ryan Richman used JVN hair products to achieve the sleek look, including items like the JVN StyleFix Hair Wax Styling Stick. Given the star's stunning hair transformation so far, we're certain Sink will continue serving looks in the years to come.
