      Results With One Use

       

      For wavy hair

      Specific improvements brought by Olaplex:

      Solve the problem of "oily scalp, dry ends": No.4 thoroughly cleanses the scalp, resolving oiliness at the roots. Simultaneously, its repairing ingredients nourish dry hair ends.

      Increase hair texture and volume: Wavy hair is most prone to flatness and loss of shape. While repairing, No.4's formula provides excellent support, leaving hair very voluminous after washing, with fuller, more elastic waves.

      Control frizz and enhance shine:       Like with curly hair, it effectively smooths frizz on the surface of wavy hair, especially in humid conditions, making waves smoother and shinier.

      For coily hair

      Specific improvements brought by Olaplex:

      Revolutionary Strengthening and Breakage Prevention: Due to its tight spiral structure, coiled hair is the most prone to breakage. OLAPLEX's repair function directly targets this, strengthening hair strands from the inside out, allowing it to withstand daily combing and styling, significantly reducing breakage and split ends. This is its core value.

      Enhanced Shine: Healthy hair reflects light better, resulting in a rare, healthy shine in repaired coiled hair.

      Improved Manageability: Stronger, smoother hair means easier styling (such as twists and braids) with less breakage.

      For curly hair

      Specific improvements brought by Olaplex:

      Repair and Strengthen: Curly hair is inherently fragile and prone to breakage, especially chemically straightened or dyed curls. No.4 significantly reduces breakage, making spiral curls more elastic and stronger.

      Reduce Frizz:       Frizz is essentially caused by numerous tiny hair breaks and raised cuticles. By repairing internal disulfide bonds and closed cuticles, No.4 delivers unprecedented smoothness, making curls more defined and defined, rather than a frizzy "cotton ball."

      Enhance Shine:       Healthy hair has a smoother surface and reflects light more effectively. Repaired curls will have a healthy shine.

      Key Repairing Ingredient:

      Bis-Aminopropyl Diglycol Dimaleate: This is the soul of the product. While cleansing, it penetrates deep into the hair shaft to repair disulfide bonds.

      The foundation of OLAPLEX lies in its patented ingredient, Bis-Aminopropyl Diglycol Dimaleate. In shampoo, this ingredient is designated as OLAPLEX Bond Building Technology.

      This ingredient can find and reconnect disulfide bonds in hair that have broken due to chemical treatments (such as perming, dyeing, and bleaching), heat styling, and environmental damage.

      Disulfide bonds are the most critical chemical bonds that determine the strength and structural integrity of hair. Repairing them fundamentally “repairs” the hair, not just provides a surface coating.

      Other auxiliary ingredients:

      Cleaning system:

      • unfold_more_doublerefreshcontent_copy

        Sodium lauryl ether sulfate:

        This is a powerful yet relatively gentle sulfate surfactant. It produces rich, dense foam and has strong cleaning power. This is why many people feel it "cleans very well." This might be a concern for users with extremely sensitive hair or those seeking a completely sulfate-free solution.But OLAPLEX has balanced it with other ingredients to make it gentle on damaged hair.

      • unfold_less_doublerefreshcontent_copy

        Cocamidopropyl betaine:

        It possesses mild moisturizing properties. As an amphoteric surfactant, it can be used as a co-cleaning agent to reduce the irritation of the main surfactant and enhance foam richness. It exhibits excellent compatibility with anionic, cationic, and nonionic surfactants, thus allowing for flexible addition to various cleaning formulations without affecting system stability.

        Conditioning and moisturizing system:

        • stat_1refreshcontent_copy

          Polyquaternium-37, Spiny Cloud Gum:

          These cationic polymers and natural gels can form a thin film on the hair surface, making the hair smooth and increasing its volume and texture.

        • stat_2refreshcontent_copy

          Glycerin, panthenol, glycosylation:

          Highly effective moisturizers and humectants can capture and lock in moisture in the hair, preventing dryness and raised cuticles, and increasing the hair's softness and shine.

        • stat_3refreshcontent_copy

          Propylene glycol didecanoate:

          This lightweight moisturizing cream penetrates deep into the hair strands, replenishing and leaving them smoother and shinier, while also providing comprehensive repair for the hair.

          Auxiliary ingredients

          • stat_minus_2refreshcontent_copy

            Functional ingredients:

            Niacinamide and arginine: These ingredients are designed to help improve scalp health and strengthen hair roots, but given the short time that shampoo stays on the scalp, their main function may be to help maintain the scalp environment.

          • stat_2refreshcontent_copy

            Anti-corrosion system:

            Hexanediol, octyl glycol, and phenoxyethanol: This is a relatively modern and safe combination of preservatives. The three ingredients work synergistically to provide broad-spectrum preservative activity, inhibiting the growth of bacteria and fungi.

            Say goodbye to greasiness and embrace freshness

            • Exclusive patented repair technology strengthens hair from the root.

              This is not just surface treatment, but repairs hair at the molecular level. Its unique Bis-Aminopropyl Diglycol Dimaleate ingredient acts like "molecular glue," finding and reconnecting disulfide bonds broken by perming, dyeing, bleaching, and heat damage.

            • The effects are visible to the naked eye; witness the miracle of "withered grass coming back to life".

              The improvement in hair condition after use is immediate. Most users experience significant changes after the first use. After washing, hair is silky smooth, requires minimal resistance when combing, and has a healthy shine.

            • Concentrated and highly effective, requiring very little dosage, it offers excellent value for money in the long run.

              Although the price is higher, its highly concentrated formula requires only a small amount to thoroughly cleanse the scalp. Therefore, the cost per use is not high.

              Suggestions on how to use

              • Use sparingly: Because it is very concentrated, start with a small amount (such as half the size of a one-yuan coin).

              • Lather thoroughly: Add water to your palms and lather to create a rich foam before applying to your hair, or massage directly into damp hair to create foam.

              • Focus on cleaning the scalp: Massage the scalp with your fingertips, allowing the foam to flow naturally through the hair strands. If needed, you can further lather a small amount of foam into particularly damaged areas from the mid-lengths to the ends of your hair.

              • Pair with No. 5 Conditioner: OLAPLEX strongly recommends using it in conjunction with the No. 5 Bond Conditioner from the same line for optimal repair and moisturizing effects. The conditioner has a higher concentration of repairing ingredients, further strengthening and replenishing the repaired hair.

              • Regular Use: Depending on hair condition, use 2-3 times per week, or alternate with other gentle shampoos.

              WHY OLAPLEX No.4 Bond Maintenance ?

              This is its most core and irreplaceable advantage.

              Fundamental repair vs. superficial covering

              Regular/premium shampoos: Their main function is cleaning and temporary improvement. Ingredients like silicone oil and cationic conditioners form a thin film on the hair surface, making it feel smooth and shiny. This is like repainting a cracked wall; it looks better, but the internal structure remains fragile.

              OLAPLEX No.4: It utilizes the patented ingredient Bis-Aminopropyl Diglycol Dimaleate to penetrate deep into the hair shaft, locating and repairing broken disulfide bonds (the source of hair strength and elasticity). This is equivalent to reinforcing a cracked wall from the inside. It doesn't "cover" the damage, but rather "heals" it.

              Why choose it? Because what you want is truly strong, healthy, and break-resistant hair, not just hair that looks smooth.

              For the target audience, its effects are revolutionary.

              Results-oriented: Solving specific, challenging hair problems

              Regular shampoo: Designed to meet basic daily needs: cleansing, smoothing, adding volume, or moisturizing.

              OLAPLEX No.4: It's designed to solve problems. It most effectively:

              Significantly reduces breakage and split ends: Strengthens hair from the inside, making it more resilient to physical and chemical stresses.

              Rescues severely damaged hair: Especially hair that has become "straw-like" after frequent perming, dyeing, and bleaching.

              Provides long-lasting frizz control:               Reduces frizz caused by damage at its source by repairing the cuticle and internal structure.

              Why choose it? Because you are facing problems such as fragile, brittle, and severely damaged hair that ordinary shampoos cannot solve.

              Although it is expensive, it offers a worthwhile overall value.

              Unparalleled sense of value and experience.

              Regular Shampoo: Typically watery in texture, requiring a larger amount to lather.

              OLAPLEX No.4:

              Concentrated Formula: Thick texture, producing incredibly rich and creamy lather with minimal usage. One bottle lasts a very long time, making each use cost-effective.

              High-End Salon Experience: From packaging and texture to fragrance and feel, it offers a luxurious hair care experience, transforming everyday shampooing into an enjoyable experience.

              Targeted Systemic Care: It works synergistically with other products in the same line, such as the No.5 Conditioner and No.3 Hair Mask, forming a complete repair system with effects greater than the sum of its parts.

              Why choose it? Because you're not just looking for a product, but a smart investment in your hair health and an effective, enjoyable self-care ritual.
