Love this product❤️
I’m really impressed with this hair mask. The texture is lightweight, so it doesn’t weigh down fine hair, but it still delivers a deep level of moisture. After using it, my hair feels soft, hydrated, and much more manageable. It smooths frizz, adds shine, and leaves my hair looking healthier overall. I also love that it rinses out easily without leaving a heavy or greasy residue. The subtle scent is fresh and pleasant, making it feel like a little spa treatment at home. It’s a great option for anyone with fine hair who still needs extra moisture without the heaviness.

Love it!
Absolutely love this! From the very first use, my hair felt noticeably softer, smoother, and more hydrated. It deeply conditions without feeling heavy or greasy, and my hair looks shinier and healthier every time I use it. It also helped tame frizz and made my hair much easier to detangle and style. This is now a must-have in my hair care routine!!! highly recommend! 💖✨

My favorite hair mask!
This is the BEST hair mask. It always leaves my hair feeling thick and smooth, and looking very shiny! And it smells AMAZING!! I will never use another hair mask brand again. On weeks where I don’t use this mask, I use Ouai hair oil and Ouai leave in conditioner. These are the absolute best hair care products and they last a long time, I feel like they are priced very well for as long as they last me.

Aromatherapy for your hair
I love the creaminess of this product and the smell. It is a little trip to the spa in my own shower. I do think it makes my hair more shiny and less dry and I will buy more when I run out.

Intense conditioning
I purchased this brands shampoo and conditioner in the past and was able to choose a free sample which I thought was this product. I remember loving the smell of the sample and decided to purchase this deep conditioner after my other ran out. I wasn’t as in love the scent as I remember and wonder if I got a different one in the past. But this deep conditioner does work well and I notice my hair is much softer after I use it. Usually I use it to detangle the dreadlock that forms in my daughter’s hair because that’s the only way to break it up. I like the simple branding of this brand and the color of the jar is neutral and clean. It’s a bit pricy but I am a true believer in high quality hair products because I get highlights and don’t get my hair trimmed as often as I should.

Best hair mask for my long, thick and dry hair. Worth the money! Makes my hair so silky smooth and healthy! Highly recommended. Little bit goes a long way and I use this one to two times a week.

OUAI Thick Hair Mask: The Parisian Declaration to End "Straw Hair"
The name OUAI Thick Hair Mask itself instills a certain confidence—a feeling of "Yes, this is the one." As a self-proclaimed Senior Household Hair Care Project Manager (yes, I’m the one who buys all the "magic potions" for the wife), I sourced this mask for my wife, three months ago. To be honest, upon first glance at the marketing copy, I had a cynical "another brand selling itself too hard" thought. After all, the journey to save damaged strands in our house is more complex than the NYC Subway maps. Its performance, however? Well, it absolutely proved that OUAI Means Yes. The formula of this hair mask is robust and professional; it doesn't stop at just "smelling nice," but truly lets its ingredients do the talking. Restoration and Resilience (Hydrolyzed Keratin & Pea Protein): Due to styling and coloring, Chloe’s ends were constantly "disobedient"—or, in professional terms, the cuticle structure needed optimization. After three months of consistent use (twice a week, strictly observing the 5-minute "meditation ritual"), we’ve clearly seen a significant boost in the hair’s resistance to breakage. That alarming "snap" sound when brushing has become a rare, almost forgotten memory. Deep Nourishment (Almond Oil, Olive Oil, Macadamia Oil, Shea & Ilipe Butters): This blend of oils and butters is like a Michelin-star nutritional feast for the hair. The texture is incredibly rich, yet a little goes a long way. Following the "quarter-size amount" direction is sufficient for My wife’s medium-length hair. Most importantly, it rinses out completely clean, avoiding that greasy, "fake smooth" feeling that plagues many heavy masks. It nails the balance. The instructions are remarkably simple: "Squeeze out excess water, apply, chill out for 5 minutes, then rinse." This perfectly aligns with the modern philosophy of Made For Effortless Routines. Five minutes—that’s just enough time for me, to brew a coffee or scroll through a few short videos, while her hair completes its transformation from "Dry Hay" to "Silky M odel." The only "con"—if I'm forced to find one—is the fragrance. It is beautiful, but if you are sensitive to strong scents, you might need a moment to adjust. For us, however, the scent provides an immediate "I just left a high-end salon" ambiance; it's a warm and joyful experience. In the past, we've used various products marketed as "repairing holy grails," which often fell into two extremes: either too light and ineffective or too heavy and greasy. The OUAI mask cleverly finds the golden mean. While providing professional deep conditioning, it maintains the hair's volume and shine. Unlike some competitors that leave the hair plastered to the scalp, looking like it hasn't been washed in three days, this mask nourishes without weighing it down, ensuring the strands possess that "Like A Virgin Hair" natural vitality. The Good (Pros): Professional Ingredients: Contains Hydrolyzed Keratin and multiple premium natural oils, delivering immediate, noticeable repair results. Quick & Efficient: Only 5 minutes for deep conditioning, perfect for a busy schedule. Clean Rinse: Leaves no heavy residue, maintains volume, and avoids the "flat top" look. The Areas for Improvement (Cons): Price Point: Sits in the mid-to-high-end segment, requiring a commitment to the budget. Strong Fragrance: While pleasant, it may be overpowering for scent-sensitive users. Tub Packaging: Less travel-friendly; requires decanting for trips. Final Verdict The OUAI Thick Hair Mask is a product that withstands both professional and (non-professional) long-term testing. It’s a genuine "hair repair secret weapon," not just a marketing trick. Who is this for? All hair types (especially damaged strands). Users seeking efficiency, quality, and who refuse to trade time for results. If you are looking for a mask that can truly repair damaged strands, eliminate split ends and frizz, and infuse a bit of "French nonchalant charm" into your routine, then, Live Life Your OUAI, buy it!

Quite pricey, but the quality really stands out. It leaves my hair well-moisturised, feels soft and smooth, and the scent is absolutely lovely. My hair looks much healthier since I started using it. I don’t usually spend more when there are cheaper alternatives, but this one genuinely convinced me to repurchase. I’ll definitely be coming back for more.

I tend to heat style my hair pretty often, and I bleach my roots without fail every month. I also use purple shampoo (which is very drying) at least twice a week. As you might imagine, my hair has been rather like a doomed man clawing his way through the Sahara, knowing all too well that the sun and sand will soon swallow him whole. Or something like that. Anyway, this hair mask was like an oasis. My hair has so much less frizz, is softer, and tangles less. I also noticed that my natural curl pattern (which has been conspicuously absent for a few years) seemed to return a little. Not sure if it actually repairs split ends, but my hair does feel much smoother. Apply it after shampooing (but before conditioning) and leave it on for at least five minutes, rinse out, then condition after as normal.
