I went to Arizona and my sister-in-law had a friend who had thin fine hair like mine but hers looked full and thick. I asked her what did she use. She told me big sexy. I live in a rural area and could not find it locally so I went on line. Of all places I found two conditionders and one large shampoo 34oz. each for around $40.00+ bucks and I ordered them. That was about six months ago and I have used about half of the shampoo and conditioner in one bottle. A little goes a long way. I don't like my hair to have sticky stuff in it and when I use this shampoo it cuts out the need for other products...
