Brand Name: Nexxus
Deal Type: Campaign Face / Ambassador
Announced: April 8, 2026
Impact: Positions Aguilera as the face of protein science–driven hair repair, while strengthening Nexxus’ celebrity-led marketing strategy across digital, social, and out-of-home platforms
- Christina Aguilera is the new face of Nexxus’ Keraphix Collection, fronting the brand’s debut “Nexxtina” campaign rooted in protein science hair repair.
- The star product of the campaign is the new Keraphix Liquid Crystallizer Leave-In Treatment, with the first creative ad dropping April 23 across digital, social, and out-of-home. A preview projection is set for NYC’s Domino Sugar Factory on April 21.
- The Keraphix Liquid Crystallizer claims to deliver 34x stronger hair in just one use, powered by Nexxus’ proprietary Keratin Resistance Therapy (KRT) technology developed over 15 years of R&D.
- Nexxus has built a clear celebrity playbook, previously partnering with Lindsay Lohan, Sofia Richie Grainge, and Hailee Steinfeld, making Aguilera the biggest name yet in the brand’s growing roster.
Grammy-winning pop icon Christina Aguilera is the new face of Nexxus’ revamped Keraphix Collection, starring in the brand’s “Nexxtina” campaign announced April 8, 2026.
Aguilera says her hair has been through it all (bleaching, crimping, highlighting) which is exactly why she connected with the Keraphix line, calling it “a total game-changer for strengthening hair against breakage.”
The collection uses KRT (Keratin Resistance Therapy), a breakthrough technology that rebuilds hair from within using liquid crystal serine amino acid, strengthening strands from cuticle to cortex, not just patching damage on the surface.
The full line includes a Damage Repair Shampoo, Conditioner, and the hero Liquid Crystallizer Leave-In Treatment, available now at Ulta, Target, CVS, and Amazon.
The partnership fits into a well-established Nexxus celebrity playbook. In 2024, the Unilever-owned brand tapped Lindsay Lohan for the nostalgic “The Style Swap” campaign, then named Sofia Richie Grainge ambassador of its TikTok-inspired Styling Line. In 2025, Hailee Steinfeld fronted “Get Hy With NEXXUS.”
Aguilera now steps in as the biggest cultural name in the lineup, much like how Crystal Renee Hayslett partnered with ORS Hair Care in a similarly personal hair care collaboration built around authentic brand alignment.
For Aguilera, beauty partnerships aren’t new territory. She renewed her long-running fragrance license deal with Revlon in September 2025, with a new Gen Z-focused scent set to launch in 2026, extending a collaboration that has spanned over a decade.
In 2025, she also teamed up with LGBTQ+ dating app Grindr as a “wingwoman,” replacing the app’s signature notification sound with a clip from her hit “Come On Over Baby” ahead of her Portola Music Festival headline set.
The Nexxus deal, much like Normani’s expanding SHEIN partnership, shows how today’s top artists are layering brand deals that speak directly to their personal identity and fanbase.
Takeaways
Nexxus is clearly leaning into a formula that works: pair a pop culture icon with a product story that feels personal, not just promotional. Aguilera’s decades of bleaching and heat styling make her a credible spokesperson, this isn’t a random celebrity drop, it’s a calculated match.
The “Nexxtina” name itself is clever branding, fusing the artist’s identity with the product line to create a campaign that feels like a character moment rather than a commercial.
What’s also notable is that Nexxus is clearly upgrading its celebrity tier year over year: from Lohan and Richie Grainge to Steinfeld, and now Aguilera, who brings global recognition and a dedicated beauty-conscious fanbase. It signals the brand is investing seriously in reclaiming shelf relevance in a crowded haircare market.
With Nexxus working its way up the celebrity tier each year, who might they tap next, and is there a ceiling to how far celebrity science-backed haircare can go? Do celebrity-backed “science first” campaigns like “Nexxtina” make you more likely to try a new hair product?
