Scalp Serum - Sérum pour le cuir chevelu

Zero star - doesn’t help with scalp/hair health

I purchased this product on a whim after seeing so many positive reviews. I already struggle with hair issues and regularly test new products, but unfortunately this one made things worse. My hair loss increased, and it also caused noticeable scalp irritation. I wouldn’t recommend this product.

Hair loss

I honestly think this made me lose even more hair around my hairline. It’s not greasy which is nice but I’ve gone thru a full bottle and pretty sure i have less hair than what I started with.

Didn’t irritate my scalp but didn’t do much if anything towards hair growth. Super expensive for not that big of a bottle

The best Ouai product

I needed a scalp serum for my dry/itchy scalp and chose this one for the added benefit of thickening. To be honest I thought Ouai products were mostly for the aesthetic but omg it’s only been a month and I have soo much new growth. And it worked to balance my itchy but oily scalp

Made a big difference already

I’ve only been using this for a little over 2 weeks and there is already a huge difference in the thickness in my hair!! Highly recommend

Visible difference in hair growth and scalp health

I noticed a difference in the first bottle I used! I saw more density that even my hair stylist noticed. However I’m on bottle 3 and I’m not seeing much of difference anymore, however it great at calming my scalp in between washes.

Severe hair loss! Not recommended at all

After two days of use I had severe hair loss, literally a bunch of hair coming of my head. I lost so much hair that I was scared I was going to have hair loss patches over my scalp. I stopped and started again and same result.

Hydrating for Scalp, Minimal Results

The scalp serum does make my scalp feel hydrated, but I went through the bottle fairly quickly. In terms “fuller hair”, I didn’t really notice a difference. The scent was pleasant and not too strong, which I appreciated. It was nice for hydration, but I would need to use more frequently to determine if there are “true” results or not. At the price point, I don’t myself wanting to repeatedly purchase to see “thickness” results. If you were strictly looking for hydration, this would be good. Since this is advertised for thickness, I wouldn’t recommend.

Couldn't use longer than a week

I was applying this nightly for a week and I felt like it gave me headaches. Nice smell though. Also felt like my hair was probably falling out even more

Holy grail

Make my hair grow like grass this product is worth every penny literally!!! Would keep purchasing this product every time I finish a bottle !! I see result only after the second use of this product 🤩 magic potion for the hair

I purchased this on a whim a few months ago hoping to find something to help my excessive hair fall. I have been using it religiously since the day o got it and I can say this is working so well! My hairbrush was needing to be cleaned out every week because it was so full, but here I am My over 3 weeks without even. Reading to empty it! The hair on my bathroom floor has all but vanished and when I wash my hair in th shower, nothing is coming out. Highly recommend!!
