OUAI Scalp Serum - Balancing Hair Serum with Red Clover Extract, Siberian Ginseng and Peptides for Thicker and Fuller-Looking Hair - Paraben, Phthalate and Sulfate Free Scalp Care (2 Fl Oz)

I love this product! I have thin fine hair and this helps make my scalp less greasy. I use it after I get out of the shower and it is not oily and dries quickly. It’s expensive, but it is worth it! This also helps with dryness and itchiness. I have psoriasis on my scalp and this helps tremendously. I also absolutely love the smell!

I’ve been using since Sept of 2024. In May of 2025, I can see actual growth! I love it. My hair is thicker and stronger, even my hairdresser commented!

5 stars because I am obsessed with this scalp serum! Best product to balance out oily and dry hair, I love using before I use the OUAI shampoo on my hair then following that the OUAI conditioner! My hair feels so soft and my scalp feels perfectly hydrated and balanced out not too oily and dry but just right there where my hair feels like it’s flowing in the wind 🥰❤️

I love this hair oil! I feel like it is working I’m not as consistent as I should be applying it but I do notice my hair being thicker

Love it my hair feels amazing

Way too expensive, doesnt work

I really like this product. Just wish is wasn't so expensive. Makes my hair soft and I have new hair growth.

I’d say the price is accurate for the quality. Doesn’t give me dirty hair. Makes my hair smell good and my scalp feels refreshed! The serum doesn’t feel oily either. It has helped my hair a lot with hydration.
