I don't have low porosity hair, but I am also finding that I need less layers of product in the summer. Yesterday I used a leave in before my styler, which I had not been doing for the last couple of washes, and my hair was terrible. Frizzy as all get out, and feels gross and producty, too. And this is a condish that my hair usually LOVES. So I think my hair was suffocating under too much product.
I'm glad you're having a better hair day today! One thing I was going to suggest last night before my iPad died was to check out this article, posted by Firefox (I think) in another thread:
As soon as I read it, I checked my gel ingredients, put away the gels with the ingredients that are bad in high dews, and I've been having much more success. All stylers are not created equal!
