I know what you went through! My hair fell out in clumps do to stress as well, what did you do to get yours to grow back?
I like using olive oil for a lot of things too. I've used it on rashes and bug bites like sand bugs. I was too afraid I'd burn to a crisp if I used it on my skin in the sun, never thought of it for my hair. I do use coconut oil on the tips of my hair so I will try a blend with olive oil. My cats are going to want to eat my hair soon! Hahaha!
