If you are a 4b then it's really tough going getting defined curls because your curl is sooo compact (like a nonstrected slinky). You need something that's going to stretch those curls to give you a more defined pattern. Now-- what to use? There aren't many great products that can be found on the ground but I've heard many type 4 curlies raving about DonnaMarie's Miracurls Curling Jelly.
My suggestion would be to go to the 4a or 4b rooms and get some solid advice. There is MUCH MUCH more traffic there vs. here and you'll definitely get great advice.
