JASONThin-to-Thick Extra Volume Shampoo, 8 oz. (Packaging May Vary)

I have fine, wavy, and thick (meaning a ton of it) hair that also happens to get pretty oily, especially after working out or not washing it for a couple of days. Most conditioners I’ve found are too heavy/will make my hair soft in the morning after a wash but end up making it look greasy and attract dirt by the end of the day, especially on days when I just rinse/throw in some conditioner and wash it out. I decided to give this conditioner a shot, and I was pleasantly surprised! It restores my hair’s natural volume, keeps it wavy, shiny, soft and best of all, does not make it greasy by the end of the day! I use a blueberry sized amount applied to my mid-lengths to ends, which seems to be enough for my shoulder length hair. I would strongly recommend this for fine, oily hair types that need just a little hydration boost. This works well with the shampoo I currently use (NaturOli Soapnut Shampoo for Oily Hair) as well as on its own when I just rinse my hair with water. It doesn’t smell great (I hate how most of the Jason products smell), but the smell does go away by the time my hair dries. If how it smells is a dealbreaker for you, though, I would probably avoid this. But for me, since it just makes my hair look and feel so great, I will probably keep putting up with how it smells.UPDATE:I’ve been using this for a couple of months now, and I still find it definitely worth the cost and putting up with the fragrance. I get the best results when I put a quarter size amount in my mid-lengths to ends, put my hair up in a shower cap, and leave it in for 3-5 minutes before rinsing it out with cold water. My hair is soft, detangled, and most importantly still has its wavy volume and is not weighed down, or greasy. I’ve switched shampoos (serial shampoo switcher here), but it still works well with my new one (OGX Hydrating Sunflower Blonde).

The first time I bought this shampoo, it was so hard to lather up I felt like I was pulling out more hairs than saving them. Then they came out with this formula and I gave it a try.Finally it lathers up quickly the first time you apply it. If you're especially grimy and need a second application, it lathers up even better and faster. No more struggling to get this stuff to clean your hair to give it volume and thickness.The old formula was so heavy that even after using 2 applications, by the next day my hair was oily looking. Now after 24 hours it still looks clean and fuller. I tried using it with Thin to Thick Extra Volume Conditioner 8 oz, which I didn't particularly care for as it is a very heavy conditioner. You really have to spend a few minutes washing it out of your hair or later in the day your hair will get that greasy look to it.Mostly I just use Jason's Shampoo and use NEXXUS Diametress Luscious Volume Conditioner, 13.5 Fluid Ounce, which is also quite a remarkable product. One time I forgot to rinse out the conditioner, towel-dried my hair, and later realized what I had done. Well, not only was my hair soft and fuller, but it didn't feel oily a day later.So now I use Jason's as my shampoo and Nexxus as my conditioner (and wash it out). The latter you can buy at CVS or Walgreens, while the former can only be bought online.But how does it work? Fantastic! As a person who has thinning hair and developing the after-40 bald spot, Jason's shampoo simply makes it look fuller, as if I had more strands of hair. How do I know this? Just by looking at before and after pictures. Before you could see my scalp and now it's beneath full head of hair. Granted, I wasn't going "bald" but it was getting bad enough where I felt uncomfortable about myself. Now I don't and it sure beats trying to remember to use Minoxidil every day and learning that it's only a temporary solution (stop using Minoxidil, hair goes back to being thin).This at least gives the appearance of a fuller head of hair so I'll keep using it as long as Jason keeps making it!

Nice fragrance. The product leaves fine hair feeling light and lovely. I do agree with another review that the manufacturer definitely needs to start taping the flip up lids so that during shipment the contents don’t leak out. My order had partially leaked during shipment and a simple piece of clear tape would’ve prevented that. I used to purchase this product a long time ago elsewhere before the present company bought Jason Naturals. I hope they didn’t cheapen the current product by cheapening ingredients or removing beneficial ones. I’m hoping to continue purchasing and using the shampoos if desired results are observed.

This shampoo helped me bounce back after losing most of my hair after having my son. It was easy to use and had no long wait time for it to work. Showed thickening hair within the first two weeks. Love, I have my hair back.

Bottles fell in shower. Both plastic bottles broke on the bottom exposing chunky shampoo. Is this a legitimate shampoo? Buying at Whole Foods, no problem. Buying on Amazon, problem.

I have no issue with this product as I have been using it for years but I was disappointed that it arrived rolling around in the packing box with a loose lid and part of the product caked to the bottle. It’s too much hassle to return it.

I like this product for my fine, naturally blond hair. It does seem to make a difference and my hair looks & feels thicker

Nice product
