My hair is better with diffusing as well. The DevaCurl line is tricky, because you have to watch your dew points. It does wonders for my hair in the summer, but makes my hair super dry and frizzy in the winter. These products are loaded with glycerin, so this could be why. They are really great products, but you have to be careful with them.
If you like aloe based products, I highly, highly, highly recommend Komaza Care Aloe My Hair Leave In. It's fantastic for me year round, and it's pretty light. Great conditioning also.
