Reviews

great stuff.

"Love this stuff. Takes such a tiny amount to do the job. It smells wonderful, suds up great, rinses well. Would buy it again."

— Nanette B. (5/5)

Smells great, makes my hair look fuller

"This shampoo smells amazing, but more importantly, it also gives me volume I don’t naturally have without any further styling necessary."

— Gabriela C. (5/5)

"Altho it felt like the products did not fully rinse out even after much effort, the result is shiny wavy hair. Day two looks good as well. Waiting to see if day 3 is ok also."

— Valerie (5/5)

"I have been using Ouai products for years now, and was so excited to see a jumbo bottle with a pump! I have an auto-immune disease that makes it hard to squeeze the normal bottles. Thank you for an amazing product and now an awesome bottle to go along with it!"

— Erin (5/5)

Great shampoo!!

"This is the best shampoo I found for my fine thin hair. I feel like I’ve tried them all. Though nothing will really thicken my hair, it does help and gives me back some confidence."

— Sherry C. (5/5)

Very Good for Fine Hair

"This OUAI shampoo does cost more than my prior shampoo, but I can feel and see the difference - my thin hair appears noticeably. thicker when I look in the mirror. So I am hooked!"

— DR F. (5/5)

Best shampoo for fine hair but please fix bottle!

"This is the best shampoo I've found for my fine hair. My only gripe is that the bottle leaks between the cap and the bottle. If they just fixed this issue, this shampoo would be perfect!"

— V (4/5)

"Love the fragrance, and the way my hair feels, after every wash! I even use it for my 5, and 7 year old granddaughters, cuz they both have gorgeous, long hair. When I comb their hair, the comb glides through!❤️"

— RoseAnne (5/5)

Noticed only a little more

"Noticed only a little more volume. Repeated use left my hair feeling dry and straw like. Pump on bottle stopped working after 3 uses. Expected better quality than that."

— Janet W. (3/5)

"The shampoo has a strong smell, but the product is very nice."

— Andrea (5/5)

Q&A

How to open bottle that does not have pump fine hair shampoo.
Hi Linda, Our standard-size Fine Hair Shampoo does not come with a pump. To open, look for the small indentation on the cap and press down on that area — the lid will pop open for easy use. ✨ I hope this helps! Please let us know if you have any further questions :).
If it sulfate free why is sulfate listed as an ingrident and sodium? Is it actually color safe?
Hi Maya, That's a great question-- All OUAI products are produced without the use of parabens, phthalates, and sulfates. The ingredient you are referring to Sodium C14-15 Olefin Sulfonate, is not a sulfate. Sodium C14-16 Olefin Sulfonate" (also known as Sodium C14-16 Alpha Olefin Sulfonate or AOS) is not the same as a sulfate; it's an olefin sulfonate, a different class of anionic surfactant with similar cleansing properties but a slightly different chemical structure. All of our products are SLS and SLES free. Which means OUAI uses alternative ingredients to help cleanse and nourish. Hope this helps!
Hello Ouai I LOVE YOUR PRODUCTS! especially the smell! But which of your four scents is the fine hair shampoo and conditioner?
Hi Kamille, Our Fine Hair Shampoo has the Mercer Street scent. It is is an outspoken fragrance that a-OUAI-kens the senses with notes of Italian lemon, Turkish rose, jasmine sambac, iris, lily, and white musk.
Is this product vegan?
Hi Maddie! Our Shampoos and Conditioners (including Fine Hair Shampoo) contain hydrolyzed keratin which comes from sheep's wool--no worries, no sheep was harmed during the process (they are basically being groomed)! OUAI Haircare products are produced without the use of parabens, phthalates and sulfates.
How often can I use a fine shampoo?
You can use our FINE HAIR Shampoo as often as often as you'd like! Some customers prefer it as their daily/regular shampoo. However, our Daily Care Shampoo's are tailored to be used as often as your hair needs!
