Extended exposure to sodium chloride (swimming in salt water, etc. ) can cause the hair to become dry and brittle. Always wash and condition your hair after salt exposure.
Sodium chloride (salt) removes moisture from your air. Prolonged use will dry and damage your hair because it will break off. Even adding oil will not help the drying effect.
Sodium Chloride is very commonly used as a chemical hair straightner. It has to be used very carefully, and only by a professional, because it is very damaging to the hair, and to skin.

That's sodium hydroxide you're thinking of. Yes, it can be dangerous and should only be used by a professional. But sodium chloride is a completely different thing. add a comment
