My 4 year old has fine spirals (3A/B, I think) but recently her top layer has become extremely dry and stringy and is losing its curl. Perhaps this has something to do with the weather? We're in extremely humid New Orleans. Our normal routine: "co-wash" twice a week with Curl Junkie Daily Fix, deep condition with Curl Junkie Deep Fix, and detangle/leave-in Kinky Curly Knot Today. Now all of a sudden it's not working anymore.

Any suggestions? A different deep conditioner perhaps?
