Introduction to Olaplex No.4 Bond Maintenance Shampoo

Olaplex No.4 Bond Maintenance Shampoo, Olaplex burst onto the haircare scene in 2014 as the world’s first bond-building treatment system. Founded by two California-based chemists, Olaplex pioneered a revolutionary technology that repairs hair damage on a molecular level. Their patented active ingredient, bis-aminopropyl diglycol dimaleate, works to actively seek out and mend broken disulfide bonds in the hair. This effectively rebuilds, strengthens, and protects hair strands from extreme chemical, thermal, and mechanical stressors.

After releasing their signature salon bonding treatment, Olaplex developed an at-home maintenance system in 2020. The No.4 Bond Maintenance Shampoo serves as the critical first step in this daily regimen. Formulated with the very same patented molecule, it gently cleanses even the most compromised hair while making meaningful internal repairs.

Keep reading to discover why Olaplex No.4 stands miles ahead of every other bond-building shampoo on the market. This article covers everything from its key features and customer reviews to where you can buy it.

How Olaplex’s Bond-Building Technology Works in No.4 Shampoo

Olaplex’s patented bonding molecule sets their products worlds apart from every other haircare brand. This pioneering technology works at a molecular level to actively find and mend broken bonds in the cortex of hair strands.

Overview of Hair Structure and Why It Breaks

Hair has a complex structure composed of:

• Cuticle: Outermost protective layer
• Cortex: Main bulk of the strand that contains protein chains of amino acids
• Medulla: Soft, innermost layer

Disulfide bonds within cortex cells act as crosslinks between organized keratin protein chains. These connections provide natural hair with structure, elasticity and strength. However, hair is vulnerable to damage from chemicals, heat tools, brushing, dying, bleaching etc. This can break disulfide bonds, strip protein, and create holes in the cortex.

How Bis-Aminopropyl Diglycol Dimaleate Repairs Hair

Olaplex’s active ingredient includes two reactive ends that seek out and bridge broken disulfide bonds to repair hair from the inside out.

Specifically, it works as a coupling agent, forming cross links between thiol groups to effectively re-link broken bonds. This allows damaged and compromised hair strands to regain cohesion, rebuild structure, restore elasticity and minimize frizz.

Olaplex confirmed the efficacy of their patented molecule through rigourous lab testing. They found it suitable for use on all hair types and textures including compromised, chemically treated, relaxed, bleached, colored, curly, coily and straight hair.

Use No.4 Shampoo for Multi-Faceted Repair

The No.4 Bond Maintenance Shampoo harnesses this same revolutionary bond-building technology to actively repair damage with each use.

As you lather and rinse, Olaplex molecules permeate the hair shaft to rebuild disulfide bonds and cortex structure. Simultaneously, the shampoo gently cleanses each strand of dirt, oil and product-buildup.

In this way, No.4 Shampoo provides multi-level fortification – making both internal and external repairs for healthier, shinier and more resilient hair overall.

How to Properly Use Olaplex No.4 Bond Maintenance Shampoo

Olaplex recommends integrating No.4 Bond Maintenance Shampoo into your regular hair washing regimen for optimal bonding benefits.

Here are simple usage guidelines:

• Frequency: Formulated for daily or every wash use
• Amount: Dispense a generous amount into palms, based on hair length/thickness
• Application: Work into wet hair and scalp, massaging to form a rich lather
• Focus Areas: Concentrate on roots and lengths, not skipping under layers
• Rinse: Rinse thoroughly until water runs clear; pat dry; style as usual
• Caution: Avoid direct eye contact

While No.4 Shampoo makes for an exceptional stand-alone wash, many users achieve enhanced strengthening and smoothing by pairing it with No.5 Bond Maintenance Conditioner. This complete system provides intense moisture while fortifying strands against future damage.

How Does Olaplex Compare to Other Bond-Repairing Shampoos?

Various shampoo brands now tout damage-erasing claims in an attempt to compete with Olaplex’s success. However, Olaplex still reigns supreme due to its patented active ingredient and dramatic treatment results.

Here’s an overview of how it stacks up against competitors:

Briogeo Farewell Frizz Shampoo

• Relies on rosehip, coconut and argan oil for conditioning
• Lacks protein-reinforcing abilities
• Cannot rebuild disulfide bonds in cortex

K18 Leave-In Molecular Repair Hair Mask

• Features peptide technology to repair keratin
• Effective but not as versatile as Olaplex
• Specifically formulated as a mask, not shampoo

Redken Extreme Bleach Recovery Shampoo

• Fortifies and hydrates with protein-enriched formula
• Does not actively repair broken disulfide bonds
• Mainly targets post-bleach porousness vs wide damage

Schwarzkopf Bonacure Bonding Shampoo

• Uses reparing silanes and conditioning agents
• Does not contain Olaplex’s patented bonding agent
• Limited ability to rebuild hair on a molecular level

As demonstrated above, while many brands offer strengthening, hydrating and reparative formulas, none contain the proprietary hero molecule that sets Olaplex apart.

Olaplex is the sole brand with patented technology that can actively find and fix broken disulfide bonds within the hair cortex. This is what enables dramatic repair and protection against all types of chemical, thermal and mechanical damage.

Before and After Transformations Documented in No.4 Reviews

Olaplex No.4 earns exceptional reviews for its dramatic damage-erasing abilities. It holds a 4.7 star average across leading retail sites like Sephora and Ulta. Actual users rave about remarkable improvements in hair strength, shine and manageability within weeks of incorporating this shampoo into their routines.

Here are some exciting before and after transformations people have experienced and documented in their No.4 Bond Maintenance Shampoo reviews:

“I didn’t think my hair could feel so hydrated and bouncy after so many years of mistreating it. The Olaplex shampoo makes my curls look polished instead of frizzy.”

“I religiously use the No.4 shampoo coupled with the No.5 conditioner to keep my highlights fresh in between appointments. It keeps the integrity so I can push touch ups for longer without losing dimension or vibrancy. Love this duo!”
