Why does a baby's hair stand straight up?

Flyaway Hair in infants and young children is an Essential Fatty Acid deficiency. I recommend supplementing (age appropriately) Omega 6's, 3's and 9's in balance. Udo's 3 6 9 oil is good for that. Or you can do it yourself, with Fish oil, Hemp Oil and Coconut oil, changing the standard oils you cook with and eat with in the home. Olive oil on flaky scalp works to remove debris, but it is high in a type of acid that can strip the skin of protective oils so not to be used more than occasionally. For young babies, best way to introduce oils is to massage body or scalp -I recommend almond, avocado or coconut, and shea butter is always a winner. Good luck!
