Query: good product with surprising benefit

Not only has it helped with hair volume but it actually kept my hair from frizzing when I was in Florida (where it ALWAYS frizzes), which was a nice surprise.As for the hair growth, since I've also been taking supplements (horsehair, biotin, Biosil, and iron), I don't know if it's this product or those supplements or the whole combinaton that has resulted in new hair around my hairline. Whatever reason, I'm using the combination. This product does help with volume, though, without drying out your hair.
