It does work!
The product does what it claims.  After seeing it, I waited more than 2 months before buying; afraid it would be a waste of money.  It isn't.  I only use it when it's raining or very humid.  I use it sparingly on wet hair before blow drying.  It does keep my hair from frizzing or curling when there's a lot of moisture in the air.  The product was not supplied to me by any company to try.
