Customers say
Customers find this shampoo effective for fine hair, making it feel thicker and softer with a smooth, lotion-like texture. The product adds copious amounts of volume and leaves hair looking fuller, with one customer noting it works particularly well for limp hair. While some customers say it’s worth the price, others find it too expensive for the small bottle size. Opinions on oiliness are mixed, with some reporting no more oily hair while others find it makes their hair greasy.

Skeptical Expectations turned to Happy Results
Happy Update: I had forgotten all about trying this shampoo (and the conditioner) 2 years ago when I came across it again and ordered the travel size of the shampoo. How could I have forgotten what this did to my hair? I recently moved to another state and something in the water, air, something was making my hair fall flat. I tried 3 different shampoos and all still same result: dull flat hair that looked limp and/or dirty the next morning. I ordered this and after one shampoo I remembered why I loved it so much! Shiny, healthy, fuller hair – look, this is no miracle treatment, but there is a noticeable difference to my hair than from the use of Biolage, Pur D’Or, and Paul Mitchel – this R+CO outshines them all (literally!). I walked in the room after I dried my hair and my granddaughter commented on how nice my hair looked and how shiny it was. And the next morning and in to the next day, so far, my hair doesn’t look limp and dirty.I’ll be ordering the full size!——–This shampoo and conditioner gave me such volume for my baby fine thinner hair! I really am impressed. My hair is shiny and soft and full and stayed that way all day. The scent is very nice too. If you are scent-sensitive, you may not like this really apparent spicy scent but I enjoyed the experience. I ordered the sample to try as I’ve been disappointed before by shampoo and conditioner claims, but this is one I will definitely re-order in the full size.Lather: Enough lather for me – I’m used to sulfate-free shampoos that don’t lather a lot.Rinsing out: The shampoo and conditioner both rinse out easily, and my hair feels thicker in the shower–there is a bit of a ‘squeaky clean’ feel, and that helps with baby fine hair.Look of hair: Very full and my hair even has some body, which it rarely does. Lots of shine.Feel of hair: soft but not too slippery (baby fine hair can be too slippery sometimes and fall flat). It feels as if I’ve been to the salon.Very happy with my order.

Thick, lustrous, bouncy FULL head of hair —this shampoo smells incredible and works FANTASTIC!
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.

Great shampoo!
Hands down the best volumizing shampoo! A little pricey but a little goes a long way. Leaves my hair full of volume without drying it out. Highly recommend

Doesnât cause new growth
This is a nice sulphate-free shampoo that cleans very well and smells nice. Butâ¦I have been using it for about 5 years and there has been no change whatsoever in my hair growth or thickness. Since the price has gone up so much, I probably will look for a cheaper alternative now. If it actually DID cause new hair to grow or my hair to become thicker, I would continue with it. But it doesnât. Itâs just a nice-smelling average shampoo.

Iâm picky.
Works well but too expensive for the volume in the bottle. Good shampoo but save your money.

Es muy caro, inviertan en el kit, el tamaño es muy pequeño y te reseca mucho el cabello, por no tener todo el kitTe alcanza para un viaje, siento que esa presentación es una muestra del producto, DEMASIADO COSTOSA
