Community verdict
OUAI Scalp Serum receives mixed-to-positive feedback, with users frequently praising its lightweight, non-greasy formula that hydrates the scalp and encourages baby hair growth. Many reviewers appreciate how easily it absorbs without weighing down their hair, making it convenient for daily application. However, multiple buyers note that it is quite expensive, heavily perfumed, and primarily functions as a scalp conditioner rather than a dramatic solution for serious hair loss.

It doesn’t make my roots greasy and actually improves the overall texture of my hair.
Looking at the ingredients, there isn’t really anything for hair growth. There are some ingredients for a healthy scalp.
My hair is not “thicker” but i do have insanely and annoyingly long baby hairs at the front of my face... so it definitely helped grow something
I swear since using it it seems my scalp has been even more dry??? I have a lot of white flakes right at the top/front of my hairline.
