Almost every baby shampoo you will find in a store doesn’t hurt your eyes but any other type will. What is the actual reason behind that? Why not make every shampoo safe for our eyes?
In: Chemistry
The thing that hurts your eyes (as mentioned by u/PierogInTheButt SLS) is strong and cheap/widely available. Making ‘adult’ shampoos not hurt your eyes would make them more expensive and/or not as good (which means you’d need more of it, making it even more expensive). You *can* get eye-safe shampoos for adults, but most people chose the cheaper/better ‘normal’ shampoos, because they’re good at not getting it in their eyes.
It’s sodium laurel sulfate (SLS) that hurts your eyes – it’s a strong detergent. Shampoos without SLS that aren’t meant for babies exist, just look at the list of ingredients and take the one that doesn’t have it.
The tears in the slogan “No more tears” by Loreal is not tears from your eyes, but tears in your hair, you know, like tearing paper apart.
