Scalp Serum - Sérum para el cuero cabelludo

I know this serum doesn’t actually have any hair growth ingredients, but I have seen a crazy increase in hair density and growth since starting to use this product consistently three years ago. The hydration this serum gives the scalp must be doing something right! I have tried basically every scalp serum on the market and even the ones people say are not greasy have always left my hair looking like I haven’t showered in a few days. This one is different, when I massage it in it dries perfectly dry and isn’t greasy. It has a pleasing smell that isn’t overbearing. I totally recommend this serum.

Smells amazing, okay results

Smells amazing! I think this did really hydrate my scalp well, but I didn’t see a difference in hair growth that I wanted. I want a perfume of this scent so badly!

This is a hard pass for me. This Made me feel terrible. I have no idea if it works because of how it has made me feel. The first time I used it I felt bad but was hoping it wasn't the hair serum making me feel bad a week later I used it again. I feel terrible once again.

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.

Love the smell and the feel. Leaves my scalp very clean even after it get oily, I’ll use it like a dry shampoo lol. Noticed a little bit of growth but nothing crazy

Not worth your money, did absolutely onthing to my hair event tho i was using it daily
