Just over a month ago, I received this product free from Influenster. Since the new year, I've been getting much more into hair and skin products. I'm not getting any younger, so I'm trying to look my best and move into my 40s with grace. I really like the scent of this product, which is kind of mi...

I am really impressed with this scalp serum so far! I have been using it for a few weeks to help with hair thinning. I use it nightly before I go to bed and I am excited to see how it ends up working!

I've been using the Ouai Scalp Serum gifted by ouai for a few weeks now, and honestly, I wasn't sure what to expect. My hair is thin and gets oily fast, so most scalp treatments either leave it feeling greasy or weighed down. Luckily, this one was different. The consistency is super light—almost like water rather than an oil—so it soaks in quickly without any sticky or heavy feeling. I usually apply a few drops before bed, massage it in, and by morning, my scalp feels refreshed instead of greasy. I've even noticed that my roots don't get as oily as quickly, which is a huge plus. I can't say I've seen major hair growth changes yet, but my scalp definitely feels healthier and less irritated. There's also no strong fragrance, just a light, clean scent. The only downside is the price—it's a bit expensive for the size, but since you don't need much per use, it should last a while. If you have thin, oily hair and need something to keep your scalp balanced without making it greasy, this is definitely worth trying. It won't give you instant thick hair, but it helps create a good foundation for healthier growth.
Loved it

I was gifted by the Ouai to try this product this serum is a game-changer! It's lightweight, smells good, and keeps my scalp hydrated without buildup. My hair looks shinier but never oily—effortless addition to my routine!

Gifted by Ouai in exchange for my review. If you're looking for a scalp serum just to provide your hair with a nice boost of moisture, this will provide that but nothing else. I noticed no difference in the fullness of my hair and feel this did next to nothing for me. Definitely not a product I would regularly seek out.
