Has anyone used this and have any opinions?

I've been hearing about it for ages, and at the pharmacy the other day they had little mini samples of it for $3 so I bought one to try.

I washed my hair this morning, and applied it as directed (to towel dried hair, through the ends then scruff it through the rest) and so far my hair feels really nice and isn't as fluffy as usual - much tamer - its still wet but usually by this stage its all fluffy and frizzy.

It just occurred to me though that I have no idea what to expect from it because I've only really heard all the hype from ads and sales people!
