I used to do this earlier in my HJ because I was still learning how to retain moisture with my porous strands. I used to section my hair into quadrants, spritz with warm water, moisturize, and apply oil (or just mix the moisturizer & oil together). Now I don't spritz to moisturize...mainly because I've found moisturizers that work well without the additional help...but spraying with water can definitely work
I do the same thing on dry hair now: 4 sections, moisturize, seal. I am currently loving Darcy Botanical's Daily Conditioner
(don't quote me though, I just started using it). Before, I used NTM leave-in for a VERY long time. I seal with Africa's Best Herbal Oil for ceramides.
