    • Thick, lustrous, bouncy FULL head of hair ---this shampoo smells incredible and works FANTASTIC!
Size: 8.5 Fl Oz (Pack of 1)
This thickening shampoo is amazing and smells wonderful. It makes your hair so clean, thick, and lustrous. Yes, it's expensive, but you only need a quarter size in your hand to get a full use. Lathers easily and fills the whole bathroom with a beautiful scent. It makes my hair shiny and bouncy. My hair stays clean and full-looking for up to three days. I was really surprised with how long it actually keeps my hair feeling super clean and super thick. I am excited to try the thickening conditioner, as well as, other products from R+Co. The way I found out about this shampoo line is from a sample pack of thickening shampoo and conditioner that I received 'free' with some perfume samples from a department store in Las Vegas. I was traveling and thought I would try out the sample pack and was blown away with the super high quality so when I got back from vacation, I made sure to search Amazon and found this wonderful full size 8.5 oz bottle. I ordered it through my Prime account with free shipping. I REALLY love this shampoo and encourage others to not think twice about the price. Get your hands on this stellar product; you will be a customer for life. ... show more

    • Excellent quality, shampoo and thickener.
Size: 8.5 Fl Oz (Pack of 1)
My wife purchases this product many times and it thickens and nourishes her hair, which looks beautiful at 75 years old.

    • I love it, but I know why you might not.
Size: 8.5 Fl Oz (Pack of 1)
After 24 years of using whatever shampoo and conditioner my mother bought, I realized I’m definitely using products way too heavy for my fine hair. I did a lot of online research and found that this was one of the most recommended shampoos for fine hair. So far, I love it. I’ve used it a few weeks now and my hair seems so light and bouncy. The smell is good, not as strong and yummy as my old Bed Head shampoo and conditioner but it’s definitely not a bad smell. Since I cut my hair about collar bone length, all I use is this shampoo, no conditioner, and no more oil for my ends and things have been GREAT. Now, the poor reviews do hold weight so here’s why this shampoo might not be for you. People were complaining that it takes a lot of shampoo to get it sudsy and clean their hair and here’s how I found this is true. On a normal day, it takes me less than a quarter amount and it suds up just fine and cleans my hair great. BUT last week I curled my hair, used a texture spray, and wore it for two days applying more texture spray in between. When I went to wash it, it did not clean my hair. I woke up to greasy oily hair. So here’s the thing, if you have longer hair or use hair products on the daily, then no this shampoo is probably not worth it. You will need a large amount to clean your hair. If you’re like me, if you have short hair that’s usually always free from products, you’ll be just fine and your hair will look and feel amazing! ... show more

    • Clean hair, wallet cares
Size: 8.5 Fl Oz (Pack of 1)
This product smells nice and leaves hair feeling very clean and conditioned. It is easy to use but is on the expensive side for the size.

    • Scent don’t make sense, but a really effective product
Size: 8.5 Fl Oz (Pack of 1)
To start, I love the shampoo. It works really well, it does a great job actually cleaning my hair, and offers great volume. It’s very thick and rich, and lasts a surprisingly long time for the size. I wash my hair every other day on average. My hair is greasy by the time I get to washing it and this stuff powers through that and dry shampoo no problem. Apparently I’m the only one that has an issue with the scent? It’s totally manageable, but it smells exactly like several of my husband‘s products. It’s not overwhelmingly masculine, but the scent is more what I would consider to be a male-oriented profile. It doesn’t linger too much after it’s washed out, especially not if you use a different conditioner. But it’s something worth noting. Definitely doesn’t diminish the value or remove any stars. It was just surprising the first time I tried it. ... show more

    • Unsure of effectiveness
Size: 8.5 Fl Oz (Pack of 1)
It smells nice and lathers well. A little goes a long way. I don’t think it does anything for strengthening or lengthening, so I’d probably opt for something cheaper or more effective.

    • Beautiful product, not sure I see a difference
Size: 8.5 Fl Oz (Pack of 1)
I am 74 with thinner hair than I've had all my life. I bought this product and while it is super concentrated and I only need a tiny bit honestly I don't know if I can tell a difference. It's very very expensive. I love the line, I've always had good results with the company but I don't think I'll buy it again. ... show more
