What do no tear shampoos have?



I remember my mother buying them for me when I was little but I still remember them still hurting my eyes. I suppose they irritate less than the other ones but how do they work?

Some people are probably going to comment here saying “no tears” means the other kind of tear, as in it won’t break your hair, which is just plain wrong. Because if any shampoo is *tearing your hair*, you probably shouldn’t use it.

Eyes are very sensitive, and normal soap or shampoo has a higher pH than the water in your eyes does. “No tears” shampoo has the same pH as our eyes to prevent that strong stinging sensation. But getting anything foreign in your eyes could still feel irritating, so if you apply the shampoo directly into your eyes it might still hurt.
