I wonder if it might be the protein. When I use a protein free gel - my Aussie Instant Freeze - my hair is not as dry as when I use gels with protein. I have LALSG and Hugo Naturals. The Hugo gel in particular dries me out and it has more protein than LALSG, but LALSG dries me out too.
That's me with FSG as my styler!!
