I'm new to this natural curly hair, and during the winter time I will always flat iron my hair. Now that I put all that away I'm trying to figure out how would I style my hair for the winter time. What leave in to use? and how often do I deep condition my hair so it won't dry up? Also the diffuser doesn't completely dry my hair and I know the cold would damage my hair when it's wet. So would I co wash my hair the night before and let it dry over night?
