When adding moisture to protective styles you have a few simple daily options. You can mist your hair with a mixture of rosemary water, glycerin, and an oil of your choice, or add a light coconut hair lotion to it. I sometimes opt to use conditioning as a daily moisturizing option. Don't assume that tucked away hair means automatic reserved hair moisture. Be sure to choose head coverings that will not dry the hair. It is good to invest in hats with linings that are smooth/silky to the touch that will not extract moisture from the hair when it is covered.
Stay moist my Naturals!
Ciao for now!
