Maybe try something different than a curl cream, perhaps flaxseed or okra gel? Some like AG Re-coil which is a curl cream containing magnesium sulphate and hydrolysed proteins both of which are curl boosters. No idea how lightweight it is tho.

Choose your ingredients and products based on your hair properties and dew points/ humidity. Many of the Deva products contain glycerin which likely won't work for higher porosity hair in many dew points. Not sure which product you mean but the Evercurl sculpt and hold cream-gel is very rich in humectants including glycerin. The Evercurl hydracharge leave in cream contains cetyl esters which build up and weigh my hair down.
