If you’ve been buying shampoo the same way since college—whatever’s on sale, smells vaguely like coconut, and promises “shine”—this is your gentle-but-firm wake-up call. We’re switching from drugstore shampoo to Olaplex No. 4 Bond Maintenance Shampoo (Amazon), and honestly? It’s overdue.

Here’s the thing about your 30s: your hair has been through it. Heat styling. Highlights you don’t regret (and a few you do). Stress. Hormones. Dry shampoo as a personality trait. That $6 bottle from the drugstore isn’t cutting it anymore, no matter how aggressively it says “repair” on the label.

Olaplex No. 4 Bond Maintenance Shampoo (Amazon) isn’t just shampoo—it’s damage control. It’s designed to actually repair broken bonds in your hair, not just coat them with silicone and call it a day. Translation: less breakage, smoother strands, and hair that feels like hair again instead of straw with aspirations.

Yes, it costs more. But you also use less. And when you realize you’re washing your hair fewer times a week because it actually stays clean and healthy? Suddenly the math makes sense. This is “buy it once, cry once” energy.

Think of Olaplex No. 4 Bond Maintenance Shampoo (Amazon)  as skincare for your hair. You wouldn’t wash your face with body soap anymore (we hope), so why are you still treating your hair like an afterthought?

We’re not saying drugstore shampoo is evil. We’re just saying you’ve leveled up—and your hair routine should too.

Note: Olaplex is also available at Target and Walmart. Several times a week, we add Olaplex No. 5 Bond Maintenance Conditioner to our routine as well.
