John Frieda ULTRAfiller+ Thickening Shampoo, Strengthening Shampoo for Damaged or Thin Hair, Infused with Biotin and Hyaluronic Acid to Strengthen Hair for Thicker Fuller Results, 8.3 Oz

This is quite possibly the best shampoo I have ever used. When I was younger, I had fine, perfectly straight hair that just hung there. As I have aged, the few gray hairs have come in coarser and a bit curly making my hair mixed. While I love John Frieda shampoos, I hate hate hate that they introduce them, I find one I like and then it just disappears and they come out with a new one. Let me keep the ones that I like! Anyway, I bought this one when they discontinued the last one. From the moment you start to lather, you will feel a difference. Thick, silky lather! I even checked the directions - you don't have to "lather, rinse & repeat". I usually do out of habit but have tried to lathering once and it does work. I want a shampoo to make my hair feel clean and not like it has left a bunch of gunk behind and this one does seem to rinse all out. And my hair feels different. Yes, it feels thicker - with more body - but more importantly to me, it feels really silky and smooth. Please don't discontinue this one - I want to keep using it!

I have never been impressed by a shampoo, until this one. My hair is now amazing, after having only used this for a few days. I will never bother trying another shampoo so long as they keep making this. I am 40+ years old and lately my hair has been meh. Dull, difficult, flat, and just lacking. I had done all the masks and treatments to no avail. Then I saw this won some sort of award for best volumizing product of the year, and it was on sale, so I thought I'd try it. It has, no joke, completely changed my life. I don't need hot tools or styling products or anything for regular day wear. Before finding this, my routine consisted of Drybar volume spray + blow dry, followed by Drybar heat protection spray + flat iron. My hair is shiny, healthy, and voluminous. I could not be happier.

Works great to make hair look fuller when used with the conditioner & spray and if you blow dry it. My hair is baby fine and shiny, this leaves my hair coarse which many dislike, but that is what makes it appear thicker. It also doesn't leave it very shiny but I was told they sell a spray for shine. My hair truly looks a lot thicker but I don't like blow drying my hair every day so I only use it when I want it to look thicker. I fear it might do damage if used every day. It doesn't leave hair greasy or sticky, the scent is nice & it is a good value for the price. I try different brands every time I read about one, this is the 1st that actually makes a difference.

My wife says it works great

I try to use this sparingly, because it does feel like it builds up in my hair, but it definitely helps to make hair look thicker, even if just temporarily. But it does also make it feel dryer and a bit stiff, which I guess is the concession for making it look thicker.
