Thin to Thick Extra Volume Shampoo Jason Natural Cosmetics 8 oz Liquid

Pleasant smell, tingly feeling and my husband only needs to use a little to wash his hair. He also doesn't need to wash twice to get his oily hair nice and clean. He likes the added body. I notice his hair looks fluffy and I like that! He hasn't been using it long so we can't say it is making his thinning hair thinker, but it's a great shampoo!

I have waited a while to rate this to give it plenty of time. I can only say that it is better for fine, thin hair than a harsh chemical shampoo. I also believe it didn't lighten my hair and helped it maintain its color as that always happens to me. As far as thickening my hair? NO Will I continue to use this? Maybe, for sure over a regular shampoo but I am open to trying other things that may help my situation. Also, a little bit goes a long way and I find I don't use as much as a regular shampoo.

I ran out of this 2 weeks ago and have used several other shampoos I found around here- even other volumizing ones. I have been embarrassed of my flat hair every day until this arrived ✔

I've been using this healthy thickening shampoo for years. A couple of times I used another shampoo and I couldn't believe the difference in my hair. This shampoo keeps my hair looking shiny and very thick and manageable. I also use the same product, but it's the thickening conditioner. Both amazing.

I have been buying this product for a few years and it was perfect for my thin hair. Ever since you changed the formula to “new and improved” my hair has become oilier and needs washed more often. It is no longer thick. You have lost a long time customer.

I have fine thin long hair. Extremely oily scalp, and very dry at the ends of my hair.This shampoo has NOT thickened my hair after 2 months of use. My Hair does NOT look more full or have more volume, nor do my wide partings look any narrower.However, this shampoo has made my hair and scalp less oily.Paired with its conditioner for the lower half of my hair (my scalp does NOT need more oil), my hair now looks even on top and bottom. On Day 2, even though its more oily than day 1, its no longer unmanageable.I still prefer to wash my hair everyday, but in the worst case, I can manage another day without a hair wash.This is the first time I can say that in more than a decade.I give this shampoo and its conditioner 5 stars.

The Jason company must think we buyers are idiots. This company has drastically scaled down the size of items-- like shampoo, conditioner, toothpaste. The containers are much smaller and they are not filled.

I love this product, and have used it for over 20 years. It really works well on my hair making it look nice and fluffy.What is even better is that the new scent is amazing, it smells great on men, without being too noticeable so its a great new feature that I just noticed.
