Today is the kickoff to the Walmart Beauty Event, and Olaplex is on sale.
Starting on April 18, Walmart is hosting hundreds of its popular Rollbacks, and one of the best shampoo and conditioners I tested is only $32 right now.
With the Trump administration’s ever-evolving tariff claims and the uncertainty surrounding cosmetics prices on the rise, now’s the ideal time for a premium beauty stock-up during the Walmart Beauty Event — happening now through April 28.
Olaplex No. 4 Bond Maintenance Shampoo & No. 5 Conditioner
Olaplex products are renowned for their bond-building technology, which helps to strengthen and repair hair from the inside out. Regular use can lead to healthier, shinier and more manageable hair (trust me, it works!)
These products are especially beneficial for those with color-treated or chemically processed hair.​
The Olaplex No. 4 Bond Maintenance Shampoo and No. 5 Bond Maintenance Conditioner are part of the brand’s signature hair care line, which has gone viral due to its ability to repair and protect hair from everyday stress and chemical damage. These two products work hand in hand, with No. 4 cleansing and reinforcing hair structure while No. 5 provides moisture, strength and manageability.
Both are formulated using Olaplex’s patented bond-building technology, which targets broken disulfide bonds in the hair — the very bonds responsible for its strength, structure and stability.
The No. 4 Shampoo is a highly concentrated formula that gently cleanses the scalp and hair without stripping away natural oils. It’s sulfate-free, making it safe for color-treated and chemically processed hair. Infused with Olaplex’s bond-building ingredient, bis-aminopropyl diglycol dimaleate, this shampoo strengthens hair from within, helping to improve its texture and reducing breakage.
I find that the No. 5 Conditioner complements the shampoo perfectly by restoring hydration, elasticity and smoothness. It is a thick, creamy conditioner that glides easily through the hair, detangling and nourishing each strand. Like the shampoo, it is also free of sulfates, parabens and phthalates, which makes it ultra-gentle.
In daily use, the shampoo and conditioner provide a luxurious, salon-quality experience. The scent is light and clean, with a soft, slightly citrusy undertone that feels fresh without being overpowering. It’s the perfect duo to purchase at Walmart, while it’s still on sale.
