As a hairstylist with over two decades of experience, I've seen countless clients struggle with dandruff. When Head & Shoulders launched their shampoo bar, many asked me: "Is this plastic-free version as good as the original?" Let's break down what really works - and what might be causing more harm than good.
How the Bar Formula Stacks Up
The bar contains the same 1% pyrithione zinc that makes the liquid version effective against dandruff. However, there are crucial differences:
- Higher sulfate concentration to create lather in bar form
- Fewer moisturizing ingredients than the liquid version
- More alkaline pH (around 8.0 vs 7.5 in liquid)
The Sulfate Problem You Should Know About
While the active ingredient fights fungus, the sulfates create a vicious cycle:
- Strips natural oils from scalp
- Causes overproduction of oil
- Creates ideal environment for more dandruff
Who Should (And Shouldn't) Use This Bar
Good candidates:
- Those with severe, persistent dandruff
- People with very oily scalps
- Eco-conscious users wanting plastic-free options
Not ideal for:
- Anyone with dry or sensitive scalps
- Color-treated hair (sulfates fade color faster)
- Those seeking long-term scalp balance
My Professional Recommendation
For occasional flare-ups, the bar can help. But if you're dealing with chronic scalp issues, consider gentler, pH-balanced alternatives with natural antifungal properties like tea tree oil or fermented rice water.
