Different and better than other shampoos
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
This shampoo is unlike any other I’ve used. I am a guy with fine blond hair that doesn’t do well with thick, heavy, goopy standard shampoos. They weigh down my hair and it ends up looking all flat and thin. I have a full head of hair. It just lays super flat, and cheapo conditioners dry it out and trash it with too much alcohol in them. This shampoo gives my fine hair volume without trashing it with a bunch of alcohol and harsh ingredients. It’s gentle. It smells nice, too, but now that I have been using it regularly, I unfortunately have become used to the fragrance and don’t notice it as readily. At first, I was a bit disappointed with the size of the bottle. It seemed small and expensive. It is definitely expensive, but it’s just high quality. It also doesn’t take much to get your hair clean, and for a guy, I have medium-length hair. I’m conservative with it, and together with the Hair Gloss for fine hair, it tames the daily greasies without frizzing out my hair. ... show more

Best sulfite free shampoo we have found

Works well for hair that is thick and traps oils- nice fragrance and makes hair really soft and shiny. Works great to use 2x a week on average!!

Perfect for my fine hair
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
I feel like I've tried all of the fine hair shampoos out there, and they either leave my hair flat or they seem to deposit a lot of product that leaves it feeling clumpy or dry after a couple of days. Most recently I was alternating between R&CO's Television and Dallas products to try to keep my hair looking good. I don't have to do that anymore! The shampoo cleans effectively with very little product. I use about a nickel size amount, which is far less than other brands I've tried. But what's better is it leaves my hair looking really silky and healthy, with a surprising amount of volume. It's not dried out or dull after a few days. I'm going to add the conditioner to my routine since this shampoo is doing so well. For reference I have fine, straight, naturally dark blonde hair. I do highlight it, but my highlights are about 6 months old right now, so my hair isn't dried out from the processing. I'm curious how this shampoo will do when I highlight my hair again, but I have high hopes. ... show more

Not for Dry/Thin Hair
Size: 10 Fl Oz (Pack of 1) Style: Fine Hair Shampoo - Full Size
Review Image by Morgan Long Morgan Long
This shampoo didn’t work for me, I personally found it to be pretty drying, both for my scalp, and especially my hair. It definitely makes you feel very CLEAN though, and I imagine it would be great for someone with oily hair that is on the thicker side. The scent was fine, I would not go out of my way to find another shampoo with this scent, but I didn’t have an issue with it. I do love the aesthetic of the bottle, it looks cute and minimal. Unfortunately the one thing I did like (aesthetic) isn’t a top concern on my shampoo choice, so I’ll be tossing the rest of this one. Ah well, onto the next! I gave it a 4/5 product score because while it didn’t work for me, I can imagine that it could potentially for someone with a different hair type. My hair: very thin strands, moderate amount of hair, length is several inches past my shoulders, wavy, light brown, ends are bleached (style is a half-bleached ombré, which is another reason why drying shampoos aren’t going to work for me), and it’s generally on the dryer side to begin with/typically only gets oily after a few days. Hope that helps. Best of luck! ... show more

Liquid gold for my hair
Size: 10 Fl Oz (Pack of 1) Style: Medium Hair Shampoo - Full Size
I was hesitant at first about spending the money on this shampoo and the matching conditioner but I’m so glad my fiancé talked me into it. I have always struggled with a flaky, itchy scalp that was an embarrassing issue for me. I have wavy, medium textured hair and a lot of it to boot. Every shampoo and conditioner I tried would dry out my hair but make my scalp so greasy. I could never find a happy medium of how often to wash my hair because I would develop flakes overnight and yes, I was rinsing my hair throughly and with the assistance of a scalp massager. With this, I now wash my hair two or three times a week depending on the weather and my activities at work (I work in a factory). My hair isn’t frizzy, it looks and feels healthy, and my scalp doesn’t bother me anymore. I shampoo my hair twice every time I wash it and I still have over half the bottle left and I get an excellent lather to clean my scalp. I definitely recommend trying. The smell can be strong for those who are sensitive to smells but it wasn’t horrible enough for me to be put off by it. I would also like to note that I’ve had this product for about 3 months now and I’m very happy with my results and look forward to expanding my of the products within this range for my hair. ... show more
