At least once a day.
I have chronic dry hair. Isk even know what to do about it anymore. It could be my diet. I Dc every week and that doesnt help either.
Maybe you have a porosity problem? Ever try Porosity control? I use that plus I do oil rinsing when my hair is really dry (See Sareca's thread). Lifesaver! Especially during 17 week stretches.
I usually moisturize everyday at least once before I wrap my hair and put on my scarf. Yesterday I did a braid-out w/ cholesterol shea butter plus (used as leave-in), sealed w/ castor oil and my hair is so moist and lively looking so, I'll see how long I can go w/o moisturizing.
