How often are you washing? A lot of times dry hair is actually caused by over washing which strips the hair of its natural oils. I've never used the Organix shampoo, but I do use pure virgin coconut oil on my hair & it has helped it a lot after going from dark brown to blonde. I only wash my hair thrice a week, I generally use coconut oil twice a week (though when I started I was using it every other day to help my hair during the bleaching process.) If cutting down on washing doesn't help, you might want to look into some deep conditioning treatments (most salons offer several options, depending on your hair type & individual needs.)
