Most Helpful Positive Review Luxurious hair results! I have fine, straight, oily, frizzy, damaged (from coloring and using heat styling tools over the years) hair type. My scalp tends to get oily but have dry, brittle strands and been in search for hair products that'll help replenish/repair, add volume, and reduce frizz all while not weighing my hair down. I was excited to try Ouai Shampoo and Conditioner for fine hair texture and been using it for a few weeks now. The 3 key ingredients as described are Biotin: helps strengthen hair, Chia seed oil: helps thicken and adds volume, and Hydrolyzed Keratin: reduces frizz and flyaways. This is everything I was looking for in a shampoo and conditioner and the results are excellent exceeded my expectations! I distinctly noticed that it adds volume while leaving my hair soft and smooth but doesn't weigh my hair down. It also has a nice refreshing scent which makes my hair smell good all day. Price may be a bit costly however, the quality of Ouai hair products is worth it imo. Highly recommend! [Disclaimer: I received this complimentary sample product for testing purposes.]
Most Helpful Critical Review Smells wonderful, but that's about it. I have fine, straight hair and I got this shampoo hoping that it would give me a boost of volume and make it look less fine. My concerns are: oily at the top, frizz at the bottom, flat hair, and fine hair.
PROS:
It does make my hair soft, as it claims it will. It tames my frizz, which is something I really enjoy. It smells SO good. A lot of people hate it, but I love it. The smell lasts the whole time in between washes, and I can't stop smelling my hair. That's the only reason why I continued to use this shampoo.
CONS:
It doesn't add any volume at all. It actually makes my hair look even flatter and thinner than before. After using this for a couple of weeks now, it looks like I have almost half the amount of hair than I did before. My scalp is now super flat and feels/gets oily more often. If your hair type is like mine, don't get this shampoo.
The cons outweigh the pros and I really wish this worked for me because I haven't found a shampoo that has a long lasting smell like this one does.

My extremely thin, oily, pin-straight, sensitive hair has been living it's best life ever since I began using this shampoo around four months ago. Like, I mean THRIVING. Magic volume all day and my shedding I was experiencing for 10 months has even slowed down. It's spendy but 1000% worth it imo because a good hair day = a good day, amirite? I could keep going, I'm so thankful after a huge struggle with hair shedding to find this miracle shampoo! The scent might put some off, but I think it smells luxurious and my whole shower smells ✨ fancy ✨ Thank you, Ouai!
Hairstylist opinion 5
Lee lee from Pflugerville
I think they entered ouai line is worth the money if you're willing to spend that much on it. The smells are very floral but I personally don't mind it.
Not for my hair 2
Lin from Greensboro
Left my hair dry, dull and feeling weird. Chunky design bottle hard to squeeze for small senior hands. Returned it after 3 shampoos. Went back to my usual shampoo, Living Proof Restore and my hair looked and felt great.

Horrible
Considering buying again 4
Kris from York, pa
Used this for a few days - hair seems more volumized but not sure about stronger yet.
So so so worth it. 5
wwp from Chicago
I'm not big on spending anything more than $10 on a shampoo since my hair is super low-maintenance. I tried this after getting a little spending money & I will never use anything else. My super flat hair looks so good that even my clueless boyfriend noticed! I love the scent & the fact that it smells amazing ALL DAY. So worth the buy! Definitely getting the refill next time.
Worked Great for Me! 5
LifeasLizzy from San Antonio, TX
My stylist at Ulta recommended this to me. When I first started using it I wasn't crazy about the scent but it grew on me. I know everyone's hair is different but this product has worked great for me! I notice after I shower my hair is not weighed down by this product at all. My hair is also not as frizzy as it used to be when I blow dry it. I have very fine hair but it has natural body due to the waviness. I style my hair with red men 25 benefits spray and then Dry Bar southern bell blowout mouse- I use hot tools and it creates a decent blowout for not going to the salon.
Shiny soft hair 5
Blondie from Sonora, California
I see a lot of mixed reviews on this, and if I would have read those first, I would probably not buy this. But I was at the store, saw it, wanted to try this brand and purchased both shampoo and conditioner for thin hair. I could not believe how amazing my hair felt. I would always alternate between salon quality shampoos and drugstore brands, because the first would weigh my hair down, and the second would dry it out, and alternating between them seemed to leave it ok. I have long hair to my waist, thin, but lots of it. This shampoo makes it feel amazing after every wash, never too dry or weighed down. Just bouncy, clean and fresh-smelling. I just ordered the 32 oz refills for both because I'm scared to go back to any other brand.
Allergic to something and it smells awful 1
MarcieM from Orlando, FL
My daughter and I both had the same reaction after using the shampoo and conditioner one time. We both have red blotches all over our back arms and face. And then the smell of the shampoo was just awful!
Would never buy this again 2
Allyssa from CA
I never write reviews but for this I had to. I have naturally pin straight hair, it's always soft no matter what I put in my hair, I have thin hair strands but a lot of hair and zero volume and I'm constantly having to wash my hair every day to avoid becoming a greaseball. I tried this really hoping I would like it and .... 30 days later it's getting exchanged for something else. It multiplied the amount of grease I usually experience, made my hair fall out and the matching conditioner made my hair coarse. I love the smell of it but not the product itself.
Do not recommend 1
Disappointed from Midwest
I really wanted to love this product, but I am beyond disappointed. My hair started falling out and not just normal shedding. I thought it was stress but it's this shampoo. Do not recommend this to anyone unless you want to thin out your hair.
Never again... hair falls out 1
stephanie from wisconsin
I initially loved this product a few years back . I purchased a box of OUAI hair products for myself and was excited to use it. Used the shampoo and after my shower i had a huge clump of hair sitting down by the drain!! I threw all the product in the garbage. never again
Made my hair fall out 1
Kris from CA
I'm not one to normally write reviews but in this case I felt compelled to. I started using this one month ago and initially loved it after my first wash. My hair felt clean and full of volume. Over the following weeks I noticed LARGE clumps of hair starting to come out in the shower. Even my boyfriend commented on seeing strands of my hair all over the house. I was optimistic (naive) hoping it was something else causing it and not the shampoo. Now 30 days in, I have bald spots all over my head and close to no hair around my temples. I've switched to a milder ACV shampoo and have noticed an immediate decrease in hair loss. At this point I now have to invest in haircare and vitamins to start the growth process, which is going to be a long battle. Hoping this review saves someone from the trouble I've had to experience.

This made shampoo and conditioner made my hair fall out by the hand fulls!!! I've always had alot of hair, but now I have bald spots and very very thin hair. Very disappointed and now have to get my hair to grow back!!
Itchy scalp, tangled hair 1
Annie from NYC
This shampoo (along with the matching conditioner) left my scalp feel so itchy - not sure what is causing this reaction but my scalp is now extremely uncomfortable. I will not use anymore.
The shampoo also left my hair incredibly tangled and the conditioner did not help. I lost lots of hair trying to detangle after.
Not happy at all about this shampoo + conditioner.
Almost perfect 4
AmberL from Virginia
This left my fine hair so soft! Including my damaged ends. But from the first use, it also made my hair more frizzy somehow? And it felt almost thinner than before. Softer but thinner.
Smells wonderful, but that's about it. 3

The smell is too much. 3
Walelia from Woodbridge, VA
I returned this shampoo and conditioner because of the smell. It reminds me of my grandmother's perfume that was too old making it smell "off." I prefer a strong smelling shampoo, but I just couldn't get past the rancid floral scent. I use OUAI texture spray which smells similar, but for the formulation of the shampoo, the smell is just very unpleasant. The shampoo and conditioner work fine, but it is nothing special. Definitely not worth trying to ignore the scent.
I wouldn't buy this again 2
Ashley from CT
I really wanted to love this product and after a few months of testing it out, I just don't think its for me. I think its an awesome formula for people with fine hair like myself but for some reason it left my scalp SO ITCHY. I'm not sure if it was due to the fragrance or what but my scalp isn't a fan. In addition to my ANGRY scalp I found that my hair was thinning out more after using it than before. Lastly, like many others have mentioned the smell is a very overwhelming floral scent, so if that is not your jam I would avoid it.
Disappointed 2
Jojo from Washington
Left my fine curly hair feeling soft and detangled after following with the conditioner, only problem is the smell! Lingers around for days, and left my scalp super itchy so unfortunately for me it's going back :( If you are sensitive to floral heads up!

Horrible smell, had seemingly no effect on my hair. Returned.
Love, Love, Love!!! 5
NurseOnTheRun from Phoenix, Maryland
I was hesitant about purchasing this product because of the price and some reviews complaining about the scent. I am actually really surprised that some people don't like the scent. I love it! Smells expensive and clean. My hair is so soft and shiny with added volume. It's not weighed down like with other products. Highly recommend!
My new hair brand obsession 5
KAVino from Greenville, SC
I am in LOVE with this shampoo (and conditioner). I first started using the OUAI hairspray and loved how well it worked and how great it smelled....so I decided to try this shampoo and conditioner since I have fine hair. It makes my hair soft and gives it volume. Also, the fragrance is intoxicating!! It smells so great but doesn't overpower. It's worth paying the extra price in my opinion.
Adds volume to my straight, fine hair; scent is nice 3
Sofia from Dallas
I have both the shampoo and the conditioner and I definitely see a difference when I use this vs other products. My hair dries with more volume and I love the scent. Idk why a lot of people seem to have an issue with it, I don't think it's that overwhelming. It's subtle and floral. I will probably keep using. My hair actually takes longer to get oily when using this product.
Amazing for my fine hair! 5
Sav from Pensacola FL
I have struggled for YEARS to find a shampoo that can hold up with my super fine and flat hair, but also still smells good for awhile since I don't wash everyday! I work at UPS and I sweat, ALOT! I still don't wash my hair cause I just have to go back the next day, so I only wash once a week. The smell lasts all week long! I'm telling you!!!! And if I need to go out and have my hair nice, the dry shampoo does wonders if it's not a wash day! Love it! And love the fact you can buy refills!
