This sounds almost exactly like my regimen. Except I only use coconut oil to detangle pre-shampoo and use an olive blend for sealing & maintaining during the week. Ill add that I also dont usually apply product in between wash days, nor do I moisturize & manipulate every day. I just spritz my ends (what needs it most) work the excess up & into the hair and seal. IF i use product its lightly all over dry hair before I section and spritz and ill use a heavy cream or pudding type product on the very ends.
I seal the length of my hair to hold in moisture, but I always go in separately and seal my ends as well. That & weekly protein (when I DC) has made the hugest difference in length & moisture retention for me. I dont PS either, just braidouts mainly.. a loose messy bun is what I wear most.
