Does switching shampoos cause hair fall?

We hear this one all the time — and honestly, it makes sense. When your hair suddenly starts shedding after changing shampoos, it’s natural to panic. But here’s the truth: switching shampoos doesn’t cause hair fall on its own. Unless you’re reacting to a specific ingredient you're allergic to, most shampoos won’t directly trigger hair loss. So what’s really going on?

Let’s start with the basics: the job of a shampoo is to cleanse your scalp. That’s it. It’s meant to lift away excess oil, dirt, sweat, and leftover product — so your scalp stays clean, balanced, and healthy. But sometimes, your current shampoo might not be doing that very well. It could be too mild for your scalp type, not cleansing properly, or leaving behind buildup over time. So when you switch to a more effective formula (like ours 👀), things suddenly feel different.

Take 2.Oh!'s Reconstruction Shampoo, for example. It’s powered by our Tri-Surfactant Formula — a smart blend of three surfactants — each doing a different job — to give your scalp a thorough, balanced cleanse. Once that buildup gets cleared out, it might feel like you’re shedding more hair. Why? Because surfactants in the new shampoo are finally lifting off debris and unclogging follicles. And sometimes, that brings out weak or already-detached strands that were just... hanging on. This can look like sudden hair fall, but it’s actually your scalp pressing the reset button.

Also, every shampoo is formulated differently — some use gentler surfactants, others use stronger ones. The way your scalp and hair respond to this shift can make it feel like there’s more hair fall, especially in the first few washes. But don’t stress — this is often just a transitional phase. Once your scalp adjusts and your hair starts getting what it actually needs, you’ll likely notice less buildup, better product absorption, and healthier growth in the long run.

Bottom line: hair fall isn’t caused by the switch — it’s often what happens when your scalp finally starts getting a proper cleanse. Give it some time, stay consistent, and trust the process.
