I've been using the Curl and Shine leave in for several months. I bought it because all I remembered from the board was that people like the GF leave-in. I didn't realize there was more than one kind! I like it because a very little amount is all I need (about pea-sized blob) and it doesn't weigh my hair down. I tend to get overconditioned so less moisture works better for me. Your poll didn't include the GF rinse-out conditioner for fine hair. I like it, too, for days when I need a little extra conditioner. It's nice and light, but does a good job of detangling and smoothing.
Couple of inches past shoulder length 3A. Shampoo every 3rd or 4th day w/ baby shampoo; Tigi Fashionista conditioner; back to Condition 3-in-1 mousse . Alternate days water rinse, conditioner and mousse.
