Natural hair and moisture

On my previous post I talked about how I had flat-ironed my hair but was never flatironing it again. I noticed that while it was flatironed, the longer I went without moisture (spritzing my hair with my water bottle and adding extra virgin olive oil) to it nightly because I didn't want it to revert back after how long it took me to flat iron, the more brittle my ends got and how much my hair seemed to break off..now that I have went back to washing it and adding water and olive oil to it nightly, my hair is so soft and is back to life. I can definitely say that moisture is key to having healthy natural hair and I had to learn that the hard way.
