I tried the kiss my face upper management gel recently and so did my boyfriend who is 3a/3b. I used when it banding my hair overnight and it seemed to give my hair nice texture. It's hard to tell if it helped with shrinkage since banding in and of itself helps. I'm going to air dry with it in a wash n go today to see how it really works.
The kiss my face gel definitely seems to leave my boyfriends hair straighter. His hair is already straight at the roots anyway but I notice that most regular gels make his hair look curlier like 3b, especially LA Looks gel. The kiss my face gel makes it look 3a. It also leaves it really soft and not coated. Hes been using that everyday in place of the la looks gel.
