I'm in my 60's; my hair is long (down to my hips). I've used every shampoo out there and always quick to try those suggested by the salon, in hopes of finding something that made my hair feel healthy and manageable, but have never been fully satisfied. So, I've always thought I had a head of trouble... until now. Before my first shampoo, I stripped my hair to get any build up off so I'd have a fresh start with Oribe. I needed only about 1/3 of the amount it would usually required to wash and condition my hair. My comb slid through my hair like I've never experienced before. No tangles! It dried very quickly. It stayed clean for a week! And it looked stunning. It looked healthy and shiny like it did when I was a kid! WOW! After a week, it was still beautiful, manageable, and fairly clean but we were going out so I washed it again. On my 2nd wash, I used less than 1/4 the amount than what I typically would use. It dried faster than it has ever dried before and again, looks like a child's hair, not old lady hair. And that's not just my opinion... I got 2 compliments from strangers when we were out! It may seem price prohibitive, but do understand that if you are like me, you will need much, much less. For me, this makes Oribe less expensive than what I was using. Oh! Also, for the first couple days after I washed it, I kept getting whiffs of very pleasant fragrances in the air, but I was by myself then realized it was my hair! It's the gift that keeps on giving!
