I use many of the Profectiv products: the shampoo, reconstructor, end strengthener, Breakfree conditioner, and the MegaMoisturizer. I like them all, particularly the MegaMoisturizer; it really IS self-heating! /images/graemlins/smile.gif I was taken completely by surprise the first time I used it: it really warmed up as I rubbed it between my palms to spread it on my hair. It was like a mini oil treatment. I have another bottle all lined up for when I finish off the current one, too. /images/graemlins/smile.gif
I use the Healthy Ends Strengthener on my ends each time I roller set; it moisturises my ends and helps them to cling to my magnetic rollers during my dry sets.
They all have the same pleasant, faintly coconutty scent, too. I applied the BreakFree to my hair just before I got my relaxer touch up last weekend (the Profectiv people actually recommend doing this immediately before relaxing) and my hairdresser went: "Mmmmmmmm! Your hair smells so nice! It smells like coconut!" Usually, I don't find coconut a particularly appealing scent in a hair product (that's why I still haven't bought the Suave Coconut Conditioner, despite the raves). The Profectiv scent is quite pleasant, though.
The products do an excellent job of moisturising my hair, leaving it lustrous, but without that greasy feeling.
By the way, there are more than four products, but I'm not sure how many.
