i think you're reffering to Joico.. I love their products too :)
And one of my secrets for the smoothest, most hydrated and healthy hair is the olive oil. Besides my normal hair masks that I use on a weekly basis, once a month.. or whenever I feel that my hair needs a little boost, I use extra-virgin olive oil as a mask. As much as my hair needs, so the quantity varies from person to person.. And I also mix it with a spoon of rum, brandy.. anything that has alcohol, to make the rinsing go easier.
I know there are lots of products, professional products for the hair care that can help you out, but I always turn to the natural stuff from time to time. And I love olive oil :)
