I'm torn. I use this a lot; practically daily, I routinely do wet pincurl sets and use Lottabody. I have fine, but fairly thick Scandinavian hair, around shoulderlength, slightly wavy, in a modified middy cut for a 30's to 50's kind of look, and partially colour-treated. It doesn't hold curls very well, Lottabody definitely helps with that. If I'm lucky I can stretch one set out for up to four days or so, with a bit of upkeep but without having to re-set it all over again.
However, finding just the right amount for your hair is not entirely easy, and it does get frizzy sometimes. Pointfix helps with the frizz, but still. In general, I set my hair towel dried, but still quite wet. I part it to the side and divide it into lengthwise sections about 2-3 cm wide, parallel to the part. I add 3-5 drops of Lottabody per section as I proceed, dividing each lengthwise section into 4-7 smaller strands and curling them. It's not an exact science, and I honestly don't know what the water to setting lotion ratio is; 2 to 1, perhaps? It's not optimal and the amount of trial and error you have to do to find a ratio that works for your hair is probably the biggest drawback with Lottabody; you need to do some work to make it work for you. It has to be diluted. It will turn out bad every once in a while, but every hairstyle does.
It does provide me with huge amounts of fluffy volume, which is a joy for someone with naturally flat and slippery hair, and apart from the occasional overdose, resulting in frizz, it performs very well. Setting lotions have become hard to come by where I live, but I have a reliable source of huge, inexpensive bottles of Lottabody and that alone makes it worth sticking with. I have never found it crunchy or sticky, but I always brush out my set when dry. Has a nice, unobtrusive old-fashioned barbershop kind of fragrance. All in all, troublesome but very much worth it.
