I thought that the leave in treatment would help my hair, and maybe it does- BUT, don't use a straight iron with it! The leave-in conditioner smells nice, coats strands of hair well, but dries a little stiff. So, since my hair was kinked in one direction, I pulled out my trusty chi straightener to straighten it, and then similar to polymers, I think that the heat kind of 'cured' the infusium 23 on my hair, resulting in little curliques of white plastic shavings! Very odd!! So, needless to say, I won't be using it very much, if I plan on straightening my hair. I must say that for a 'healing and repair' type of product, it's still quite cheap. I know my mom used it way back when, so I think it's a good product.
