Do you find your hair does not get matted when you moisturize in other situations? Frequent moisturizing always causes my hair to tangle or, eventually, mat. Because hair shrinks up more when wet, tangling more. It's why Im the rare person who doesn't believe in moisturizing my hair all the time; I get bad results. I moisturize once, at most twice, in between washes, when I also detangle.
But as a rule, I notice less matting and tangling in braids than anything else, because they hair can move around less.
