Thin to Thick Shampoo by Jason - 8 Ounces (Packaging may vary)

My hair has always been thinner in the fall and winter, usually starting in September, with the beginning of the school year. With a little research, I realized that my hair probably needed more Biotin. So I picked up a bottle of Thin to Thick Shampoo with Biotin, and my hair began to improve from the first shampoo. Now I use Thin to Thick all the time. It's a quick, easy way to healthier, more beautiful hair.

Jason's "Thin to Thick" Extra Volume shampoo and conditioner have been long time favorites. I would love for it to come in a larger size bottle, but have searched everywhere and can't find any. My hair is very fine and although I have plenty of it. Because of the thinness of the strands, it lays flat on my head and requires either teasing or a volume producing shampoo/rinse. I highly recommend these products for clean feeling, pleasant smelling and easier to style hair..

I've always had thin hair. This shampoo works the first time u use it. You can feel it getting thicker as u wash your hair. You need a good conditioner afterwards. I love that! If you have thin hair, this is the way to go!

It really does make my hair better--more volumnous, but also silky and shiny--I have extremely fine hair and want more volume, but prefer non-harsh ingredients. The ingredients here say it all--excellent things in this shampoo.

My hair is very wavy but it lacked body and shine. This product contained both the body and shine, and I might say softness also. That I needed. I would recommend this product to anyone. Pricey but worth it.

I've been using it for a month, it really does make my hair feel fuller. My only complaint is it doesn't lather well do I feel like I have to use a lot of product. I like the smell too.

My two bottles arrived loose and unsealed and leaking in an Amazon package even though I ordered from Walmart. Since the white bottles are also different from the blue Jason bottles I am used to and the consistency is different I will not use them as I fear they may have been altered by the dealer who sent them....."Kory and Hammer"

Not the Jason Thin to Thick Shampoo I've been using for years. Item seems suspicious. Bottle arrived with no seal but packing tape over lid. Liquid is pearly white. Jason Thin to Thick Shampoo is clear. Smells like cheap toothpaste, not peppermint and other herbal essential oils that Jason Thin to Thick usually smells like. No lather, whatsoever. Just SO weird. I have no idea what I washed my hair with, but it wasn't Jason Thin to Thick!

I am terribly disappointed in the current shampoo. It does NOT do what the shampoo used to do. I wrote the company the return with the old formula, but they never responded, which is very poor for what was once a good company. Maybe, if more people complain, they listen???

i never got my order they sent the wrong item 3 times and charged me each time to correct it.
