I move you try a series of experiments as I'm not sure the length could have changed it that much. I think it's more styling technique or how innately curly the hair is. (The reason I say this is because I can change my hair back to wavy really easily and make it more curly easily depending on what I do and what I use.) Try one day just mousse. If that doesn't work, mousse plus a modicum of gel. If your hair is healthier now it should retain its curl even without product. My hair is a very healthy 2C now without product and it takes a modest amount of product to boost it. That wasn't the case two months ago. I imagine your hair is wayyy healthier than mine after all the TLC you've been supplying it.
