I really don't speak the language of science so can someone explain what humectants and dew points really mean for hair and what role glycerin in products really plays in all this. Also opinions on if I'm a wavy or curly? Sometimes I get tight ringlets but it has more characteristics of a wave, like it looks better if I apply product when damp etcWhat are humectants? And other questions, help!-imageuploadedbycurltalk1359672968.652450.jpgWhat are humectants? And other questions, help!-imageuploadedbycurltalk1359672982.749342.jpg
