This works. Trust me.
I have really fine hair, and not heaps of it, and for years have looked for a product that gives my hair body, instead of being lifeless and limp. THIS STUFF WORKS!! I never use a hairdryer but just scrunch it through wet hair from roots to tips (you only need a tiny amount) and let it dry naturally. It's slightly 'crunchy' when first dry, but this quickly goes with more scrunching. I'm buying more because I don't want to risk ever being without it. It's seriously effective. Even after a couple of days, hair brushing and styling. Highly recommended.
