If I sell you shampoo with hydrochloric acid in it, and some gets in your eyes and you're permanently blinded, should I be held blameless because "obviously getting soap in your eyes hurts?"
It is my right to buy shampoo with hydrochloric acid in it without the nanny state getting in the way. Sane adults don't blame someone else when they put hydrochloric acid in their own eyes.
I would say that it's my right to have the guarantee that there is no hydrochloric acid in a hygiene product, especially one that can get near sensible parts of the body like your face and your eyes. Sane adults can blame someone when they buy a product whose properties do not match those of what the product is supposed to be.
It may be your right to buy hydrochloric acid and to pour it over your head, but actually, that's wildly different to what you said.
I honestly can't tell if you're being sarcastic or not.
On the off chance that you're not, though: you can buy hydrochloric acid and pour it in your eyes if you really want to, but you should also have an expectation that ordinary hair care products won't have surprise deadly acid in them. Similarly, you can pour boiling water in your lap on purpose if that turns you on, but no one should be handing you a cup of flesh-melting liquid and telling you that it's fit for immediate consumption.
