can leaving salt spray in hair...

yes

 

Sea salt makes them felt like crazy ^^ but I never spray salt on my scalp.. my bf told me why salt desinfects wounds: it literally BURNS away part of the tissue. Thats why you die if you eat a cup of salt.

 

While it may burn your mouth and stomach tissue, eating so much salt would dehydrate you. Humans are made of mostly water (that's what's in all of those cells!), and salt absorbs water.

Conversely, you can die from having too much water as well.

Too much of anything will kill you,
