OLAPLEX, CREATORS OF THE #1 PRESTIGE SHAMPOO AND CONDITIONER* EXPANDS ITS BEST-SELLING RANGE WITH HIGHLY REQUESTED FORMULAS FOR FINE HAIR.
New launch marks continued expansion of OLAPLEX’s wash care range, delivering customizable solutions across hair types.
OLAPLEX Holdings, Inc. (“OLAPLEX”), a foundational health and beauty leader renowned for its pioneering bond-building technology, announces the launch of its newest innovation: No.4FINE and No.5FINE Bond Maintenance® Shampoo and Conditioner, the first-ever system from OLAPLEX designed specifically for fine hair. This clinically proven duo delivers 2X volume and 2X strength—instantly and all day—with a featherlight formula that never weighs hair down.
The No.4FINE and No.5FINE system combines the brand’s breakthrough bond-building technology with a new level of tailored care, equipping professionals and clients alike with performance-driven products that meet the unique needs of fine hair. This launch represents a pivotal moment in OLAPLEX’s wash care evolution—rooted in scientifically advanced formulas, designed for customizable routines, and delivering instant, visible results.
At the heart of this innovation is a mild amino acid-based surfactant that gently opens the cuticle just enough to cleanse effectively without stripping. This advanced cleansing technology is specifically suited for fine hair and works in tandem with OLAPLEX’s bond-building molecule. Working in synergy, the regimen hydrates, repairs, and strengthens while delivering volume and structure that fine hair can feel instantly.
The system is powered by a trio of advanced, fine-hair-friendly ingredients that deliver visible volume without compromise. Flexible Polymers help lift hair at the root, creating long-lasting volume and body without stiffness or buildup. Low Molecular Weight Hyaluronic Acid infuses strands with deep hydration, leaving hair soft, supple, and light as air. Finally, OLAPLEX’s proprietary Hydra-Balancing Matrix ensures weightless moisture and oil control, keeping fine hair clean, fresh, and bouncy throughout the day.
No.4FINE Bond Maintenance® Shampoo is an ultra-light, clinically proven formula that strengthens, repairs, and helps prevent future damage caused by heat styling, environmental stressors, and salon services.** It gently removes buildup without stripping essential moisture, leaving fine hair soft, clean, and full of lasting volume. The result is hair that feels refreshed, protected, and visibly lifted at the roots for effortless movement and body.
No.5FINE Bond Maintenance® Conditioner complements the shampoo with a weightless, high-performance formula that hydrates, detangles, and smoothes without flattening fine hair. Clinically proven to reinforce the hair fiber, it nourishes each strand to improve softness, resilience, and shine—while helping build volume, body, and bounce that lasts throughout the day.
When used together, the No.4FINE and No.5FINE system delivers transformative, visible results—2X volume instantly and all day, a 60% reduction in breakage, and clinically proven strength, repair, and protection against future damage** all while being silicone-free, sulfate-free and color safe.
“We’ve listened to our pros and our community—there was an overwhelming demand for more customized routines tailored to hair type,” says Amanda Baldwin, CEO of OLAPLEX. “This launch is more than just a new system—it’s a strategic evolution of OLAPLEX’s wash care portfolio, expanding our presence in the prestige hair care category and reinforcing our commitment to delivering personalized, high-performance solutions for every client, every hair type. Shampoo and conditioner aren’t just the beginning of your wash day—they’re the beginning of every style, every look, every possibility.”
This expansion comes on the heels of OLAPLEX’s original No.4 and No.5 Bond Maintenance® Shampoo and Conditioner—now the #1 Prestige Shampoo and Conditioner in the U.S., according to Circana*. With this momentum, the brand continues to lead the industry with its category-defining performance and strategic product innovation.
“A great hair day is a confidence boost, and OLAPLEX exists to make that a daily reality,” Baldwin adds. “Our products will repair and transform in the most extraordinary of circumstances—but it’s their daily power to build foundational hair health and deliver lasting results. Better science means better hair days, and endless possibilities.”
The launch of No.4FINE and No.5FINE marks a pivotal moment in the ongoing evolution of OLAPLEX’s wash care portfolio, reinforcing the brand’s commitment to delivering personalized, high-performance solutions for every hair type—now available for both consumers and professionals, including back bar sizes for salon use. The existing range already includes beloved staples such as No.4 and No.5 Bond Maintenance®, the original duo formulated for all hair types; No.4P and No.5P Blonde Enhancer Toning System, designed to brighten and neutralize tones in blonde, lightened, and gray hair; and No.4C Clarifying Shampoo, created to effectively remove buildup and reset the scalp and strands. With the addition of No.4FINE and No.5FINE, the collection now offers a truly customizable routine that spans damage repair, hydration, scalp health, and now targeted volume and strength for fine hair.
OLAPLEX is innovating beyond damage repair to unlock foundational hair health. Guided by a science-first approach, the brand continues to equip professional stylists with the tools to transform hair at the chair, while empowering consumers with the freedom to style without compromise.
