It does help. But only spray your hair with it when you plan on washing within an hour or 2. If left for long periods, it starts to over dry your hair and scalp, making your scalp itchy and flaky, and your hair dry and brittle.
Also, the salt from pet stores is better than normal table salt. They use it for aquariums to make the water just like ocean water in salinity.
