It's interesting to see the wide swath of opinions and reviews of people's impressions based on their individual chemistries and hair types. Personally, as an older gentlemen with very fine and thin hair, I found this shampoo to be wonderful. Nothing is going to make you imagine you have a full head of hair when, well, you don't. But this makes my hair feel very clean and fresh without being weighed down or coated. I only use a small quarter sized dollop and it gives sufficient coverage and cleansing while rinsing out easily. I expect it to last 6 months or more at this rate so although it's a bit pricey, I expect to be a repeat buyer. Previously, I've been using a seaweed based shampoo which I also love and have purchased repeatedly. I also like the simple graphics and sturdy metal container, though that has nothing to do with the shampoo performance.
