I don't understand how it is necessary. I think it would just dry your hair. How is drying the same thing as removing product build up? Pantene has salt for sure, and I THINK Suave does too. erplexed
Hmmm... maybe they work like a scrub? I dunno, but u can add baking soda to ur shampoo to clarify as well. Maybe salt works the same way as baking soda.
I'm pretty sure they add salt in there FOR its drying (absorbing oils and build up) purposes.
I've seen that too.. and I wonder about the amount that is actually added.
I'm hoping that it's just a very very small amount just so it helps to clump up and absorb any "waste materials" on your scalp/in your hair.
I think I know the answer to this one. It's because when people have hard water (that is, water with minerals like calcium in it) and they use water softener systems, the systems often rely on salt -- because salt softens water. You'll sometimes see salt in soaps too, especially in countries where there is a lot of hard water (like this one *points to location*).
hi,
think the answer is that most build up is due to salth that is not water soluble e.g calcium carbonate, when you add salt (Nacl), the reaction btw the two forms more soluble salt e.g calcium chloride (cacl2). obviously there is intermediate step involved i think an acidic solution will be needed.
Anyway you get the gist graduated from high school 10yrs ago so cant remember much of high school chemistry.
