Concerning your question on gel for second day hair, I think it helps maintain your curls for more than one day. Sometimes, I use a curl cream instead of gel. It gives an excellent curl pattern to my hair, but by the next day it is more frizzy compared to using gel. You should try it (gel) and see if there is a difference for you.
