Luxurious hair results!
I have fine, straight, oily, frizzy, damaged (from coloring and using heat styling tools over the years) hair type.

Not good for fine coily hair
I watched a video by Ouai talking about stripping the gimmicky labels and giving a straight forward shampoo and conditioner set that tackles the common issues of each hair texture. FYI: Hair texture (not to be confused with surface texture) is the size of the hair strand. They come in fine, medium a...

This conditioner has been such a lovely surprise! I have fine hair with dry ends, so I need something that moisturizes without making my hair look flat. I love how creamy and smooth the formula feels. After rinsing, my hair feels noticeably softer, and the ends look much healthier and less frizzy. It gives my hair that silky, freshly styled feeling without weighing it down. Plus, the fragrance is amazing and stays in my hair beautifully! Gifted by OUAI.
Loveee
Gifted by OUAI. Having fine hair, I'm always careful with conditioners because most of them make my hair look flat or greasy. This one feels so lightweight but still gives my ends the softness and hydration they need. I love how easily I can brush through my hair afterward without dealing with tangles. My hair feels silky, smooth, and much more manageable without losing its natural volume. And the scent is absolutely beautiful! Such a lovely addition to my hair routine.
Perfect remedy for thin hair!
complimentary from ouai. I've really enjoyed using the OUAI Fine Hair Conditioner! 🤍 Since dealing with postpartum hair loss, my hair has become thinner, so I'm always looking for a conditioner that adds softness and moisture without weighing my hair down. This conditioner leaves my hair feeling smooth, hydrated, and easy to detangle without making it feel greasy or heavy. I love that my hair feels soft and manageable while still maintaining that lightweight feel. It's a great option for anyone with fine or thinning hair who wants hydrated, healthy-looking hair without sacrificing volume!

love
I really like how lightweight this conditioner is! Having fine hair, I always struggle to find conditioners that make my hair soft without leaving it feeling heavy or greasy. This one does a great job of making my hair feel smooth, hydrated, and easy to brush through. It also smells amazing and pairs perfectly with the shampoo! gifted by ouai

- Q
I would like to try your conditioner for fine hair (my niece loves it!) but have contact dermatitis and an allergy to linalool. Since you list parfum as an ingredient, does this contain linalool?
- Asked by MJBShopper
- Official Answer By OUAI - Brand EngageOur Fine Hair Conditioner does not contain linalool. You may find the full ingredients' list on the product page. However, we do not produce our products in linalool free facilities so we cannot make the claim that they are free of any linalool ingredients.Was this answer helpful to you
- Q
Should I use fine or medium shampoo/conditioner if some of my hair is fine and some is medium?
- Asked by Erin
- Official Answer By OUAI - Brand EngageYou can absolutely mix and match! It's important to do what feels best for your hair - everyone's routine is different! We recommend using Fine Shampoo or Conditioner when you're looking to add volume and bounce, and strengthen and thicken fine hair with just the right amount of hydration without leaving hair greasy or OUAI-ed down. We recommend Medium Shampoo & Conditioner if you're looking to add shine, eliminate frizz, or a little extra hydration.Was this answer helpful to you
- Q
Why is there isopropyl alcohol in this product? Wouldn't the alcohol tend to dry the hair?
- Asked by knitter
- Official Answer By OUAI - Brand EngageOUAI here! Isopropyl alcohol can sound drying, but in this case, it’s included in a very small amount to help the formula perform better. Isopropyl alcohol helps dissolve and evenly distribute key conditioning ingredients, ensuring they coat the hair smoothly. Because Fine Hair Conditioner is balanced with moisturizing and nourishing ingredients (like oils, butters, and emollients), the isopropyl alcohol doesn’t dry out the hair — it actually helps those ingredients absorb more effectively, leaving hair soft and manageable. So while “alcohol” can sometimes have a bad reputation, not all alcohols act the same way — in this formula, it plays a functional role that supports conditioning rather than drying. I hope this helps!Was this answer helpful to you
